AirVenture 2008AirVenturewas another big success. Although EAAreported attendance as "about the same as last year;' itdidn't reel quite as crowded. There were still enoughairplanes and people to boggle the mind.The ABS tent was again busy and amacted good crowds.Lots of good hangar flying, some excellent technical presentationsand merchandise sales were healthy. I knolV it wasbecause of the camaraderie and opportunities for technicalenrichment, and nOlthe free soft drinks and popcorn!Two things have really enhanced the ABS Oshkosh tentexperience: the air conditioner in the general area and the flatscreenTV monitor in the presentation area. Both were contribmedby Kevin O' Halloran of Cordell, Oklahoma-a longtimefriend and supporter and volunteer extraordinaire.Kevin not only helps ABS but is the principal reason thatBonanzas to Oshkosh gets to park in the same area and enmasse. EAA does not allow any "reserved" parking atAirVenture but Kevin, with the help of his young friend MaxRingo, manages to hold off the brand C, P and Ms so B20shcan park and camp together. In addition, when the B20shersclimb out of their planes, there's Kevin with his famous margaritamachine, beer and pizza.Larry Gaines, the leader of the B20sh flight, wanted to dosomething special for Kevin and Max this year. So he invitedMax to fly Larry's plane and lead the B20sh flight. Larrymonitored everything from the right seat, and actually onlyspoke once on the radio-a new record for this talkative guy.Larry flew with Max a couple of months ago to give himsome experience in the left seat of his plane, and to give himsome pointers on leading the flight. And it came to pass, andMax (and Larry) did an excellent job.Larry is not only benevolent to young people like Maxbut is correspondingly so to. ahem, mature graybeards like.Kevin O'Holloron-o long-time supporter and ASS member~ntributed a flotscreenTV monitor for use 01 ABS events. The big screen really enhanced the ABSTent Topic presentations.for instance, me. He invited me tojoin him and Jim Sanders, CFO atHawker Beechcraft, in the 3-shiplead element of the flight. It was anhonor that I truly appreciated.If you haven't yet experiencedthe B20sh flight, you're missing thepremier Beechcraft flying event of the year. When the towercontroller in Rockford says, "Bonanza lead and flight, clearedfor takeoff," that's clearance for about 100 (this year 93)Bonanzas and Barons. And when about an hour later, Oshkoshtower says, "Bonanza flight , cleared to land, and welcome toOshkosh;' that's clearnnce for the entire flight and the tradi ­tional beginning of AirVenture.This is the safest way to get to Oshkosh as well as themost efficient and the most fun. The entire flight lands in about14 minutes! There is no other way that about 100 airplanescould land from the Fisk/Ripon approach in anywhere nearthat time.Larry has also been very generous with his time andadvice to other type formation groups. He has helped a groupof Grumman pilots develop their formation skills and at thisyear's Stockton (California) formation clinic I met severalenthusiastic Cirrus pilots, including the current and past presidentsof the Cirrus Pilots Association. Larry also providedsome critical advice to the Cessna pilots to avoid violating theEAA's parking rules.Next year Larry is contemplating a world record B20shflight! If you're not up on your formation skills, contact him orcheck the B20sh.org website for a clinic near you. Pan of aworld record; now that will be something!Our new ABS websiteIsn't it great! I know it seems like it took forever, but wewere able to make real progress when IT Specialist KurtSchneweis was hired. With guidance from Director Steve Blytheand Media Committee Chairman Bill Stovall, and, of course,input from the entire staff, the project finally came together.Now that we have the new homepage in place, check itoften for improvements in all supporting pages.Lexington ConventionOur convention is almost upon us and I'm looking forwardto it. If you haven't registered yet, don't despair. Youhave missed the Early-Bird discount, but even so, it 's still thebest bargain in Beechcraft education, entertainment and funwith your fellow Beech lovers and a great trade show to boot.Check the Ride Share page on the website and travel for afrnction of the cost. I hope to see you there! -ArtABS September 2008 www.bononza.org Page 10932


BEECHCRRfT OF THE MO~THN211EBAllan BergBrooklyn, New York1969 D55BERG'S BEAUTIFULBLACK BARONy first ride in an airplane came~when I was about six. My fathernew me over the Hudson River inan Aeronca Champ. We were fairlylow and for as far as I could see therewere boats tied together in groups of 5to 15 where they had been mothballedsome years after the end of WW11. To ayoungster, this was very exciting.Actually, it would have been exciting toanyone!It was a long time after that fustride that I started nying. I went througha progression of Cessnas, a Commanderand then a Cessna 303-my first twin. Itwas a great plane, but a little on the slowside. Next I bought a Cessna 340, then Igot a Bonanza A36.After I sold the Bonanza, it just sohappened that a friend was selling his1969 Baron. I had been looking aroundfor a newer plane, but when I saw whathe had done to this 055, I decided it wasthe ship for me.N211 EB had been brought up todate and should be a no-problem airplane.And that is exactly the way it hasbeen. Many upgrades had been completedbefore I acquired the plane andeverything was in excellent workingcondition.Making it beautifulAfter acquiring a plane in excellentmechanical condition, I had the enjoyabletask of beautifying. So I had theentire interior redone and added a fewnew touches of my own. These includedtwo-tone leather, the Beechcraft logoburned into the headrests, and angularpockets on the back of the front seats.Super-soundproofing really helpedquiet it down .After the interior was completed, Ihad a very good-looking and comfonableinterior, but the exterior was reallytired. Several friends had their planespainted at Sky Harbour in Goderich,Ontario, Canada. So when I new toGoderich to pick up one of them, I hadan opponunity to discuss the possibilityof having my plane redone.When I finally decided to do thepaint job, I new to Canada again and metwith Sky Harbour's design people. Overa few e-mails, we hammered out an aUblackdesign with a chameleon accent.This was the first airplane at SkyHarbour to have the chameleon paint.

But then I felt itstill needed a little something more. Soa year later I flew back to Sky Harbourto add a beautiful metallic go ld accentstriping. This really made the paint jobsparkle! They laid down that pai nt like itwas a sheet of glass.Sky Harbour has an excellent staffand runs a very professional operation. Ireceive lots of positive comments on myBaron. Many times when I fly into newairports, the controllers comment on theoutstanding paint design.The enttre mterior was redone including having theBeechcroft logo burned info the heodrests.One thing led to anotherWhile I was redoing it, I alsoreplaced the windshield and the pilotand copilot side windows. I added ventsin both windows. All the rest of theglass was in excellent shape; just neededto be polished out a little.Then I added some Teflon tape onthe leading edges of everything, andinstalled new wing root seals. I had thestep rechromed, put on new door sealsand had the spinners and fuel caps polished.By the time I finished at SkyHarbour, I had spent much more than Ihad planned!The engines were on the high-timeside and running strong until this lastannual when one engine just didn'tmake it. At that point I felt it was timefor both of them to be replaced. So Ichose RAM IO-52OCB engines. RAMwas an excellent choice and their techsupport i terrific.After deciding to replace bothengines, I felt it would be best to do thefirewalls forward. WeU, it turned out Icould have put a whole new addition onmy house for what aU that cost! But thegood thing is that, where I previouslyflight-planned at 195 knots, I now haveseen as high as 200 knots. What a bargain!I have learned that you practicallycannot overload this Baron model; it hasa useful load of 1,941 Ibs. I normallycruise at 195 knots and burn 24 to 26gph at 8,000' to 9,000'.The difference between this twinand almost any single is that I can climbout at up to 2,500 feet per minute. Veryfew singles can cruise at speeds up to200 knots and I have tbe safety of twoengines. At 24 gph. I burn only about 8gph more than a single engine-and stillshow between 190 to 195 knots (2,500rpm at 8,000' to 9,000').The airframe now has about 3,700hours. All in all, this is a great airplanethat outperforms many others and is areal eye-catcher.@

Why the"might be able to do" part? This customerand I share a passion for the classiclook and feel of an older Bonanza, Inthe nostalgic spirit of that idea, wewanted to achieve a panel design thatwas the best of two worlds, one beingthe appeal of aforementioned classicvintage Bonanza, the other blending inas much state-of-the-art glass equipmentas possible,After a couple of pilot-to-pilotmeetings, priorities began to take shapeon paper. As we discussed the manydetails and possibilities, we selected,sketched, moved, resketched and deleteda number of options,Not all panel ideas are as undefmedat startup as this one was, Some are morestraightforward, often allowing the customerto have an accumte design drawingwhen the airplane is dropped off, Thispanel was unique to the point that thiscustomer left with preliminary sketchesthat defined three groupings of details,Group one is all the stuff I knolV lVe cando, Group two is all the stuff I'lIlfairlycerrain lVe can do , And finally, there isgroup three, the long-shot sllIffI know this sounds a little precariousbut if you are trying to build a trulyPage 10937www,bonanza,orgABS September 2008


custom panel , tailored to the needs of aspecific pilot, this initial assessment ofundetermined possibilities is necessary.No matter how experienced and creativea panel builder is, there's alwaysroom to leam new ways of doing things.This open-mindedness is fundamental toachieving a higher level of success.There is nothing "custom" about doingthe same things over and over.A trusting partnership between theowner-pilot and the panel builder is thekey to the success of this process.Usually it's about one-third of the waythrough the job when a tinal drawing issent to the customer. The parties mustbe in close communication as the variousoptions are explored and finalized.Do we end up with every componentexactly where we want it? No. Themission is to build a functional panel fora specific customer with as few compromisesas possible.We, like many panel builders, havesome tried-and-true designs that withminimal changes will work well formany of our customers. With newequipment coming to the market almostevery month, this panel design gamewill probably remain in a constant stateof flux. 1 love it'A word to the wise: Precheck everysystem and component related to thepanel before starting the teardown. Weeven do a pitot and static leak check.Not all of the problems in these systemswill be behind the panel. U the problemis in an instrument, it can be sent out forrepair while the panel work is beingdone. Good planning saves down time.Pretesting protects both the customerand the installer by estabushing,up front, the status of those often oldand certainly delicate components. Thiseliminates the potential for the fingerpomtlngcontest of HIt was workingwhen [ brought the airplane in." Onecan spend a lot of time troubleshootingnewly installed wiring only to find outthat the box is bad.TIME TO GET ORGANIZEDWith the plan and wish list in hand,it's time to get organized and tear into theproject. The key word here is "organization."Have lots of plastic sandwich bagsfor small components and related parts. Adigital camera will help a less-than-perfectmemory keep track of lots of details.Never unhook or cut a wire withoutfirst understanding and confinning itsfunction. That means that a thoroughstart-up check of all systems is anabsolute must. "An ounce of preventionis worth a pound of cure." Remember tomark every wire.The actual teardown process beginsby removing the crew seats, left forwardside panel, right side kick panel, lowerpedestal, fl oor carpets and paddedglareshield.Start thinking of ways to keep stufffrom falling into critical places below thefloorboards or into the control cable tunnellocated immediately and below thethrottle/prop/mixture controls. We havemore than once found something like ahose clamp that had fa llen down intothis area and lodged itself between apulley and a cable. This resulted in afrayed cable and a worn pulley, obviouslyrequiring replacement of theseexpensive components.To prevent this from happening, welike to stuff appropriately shaped piecesof 2" thick upholstery foam into theodd-shaped openings around these criticalareas. This works great and doesn'tcost much money.STRUCTURAL RELATIONSHIPSBefore we start drilling off the oldpanel components, it's important tounderstand the structural relationshipthese pieces have with the airframe. Thelower span-wise truss and the old aluminum,permanently-attached paneloverlay are part of the support structurefor the center control console components,as well as a span-wise cabin supportthat helps maintain the structuralintegrity of the main cabin and doorframeat the forward end.Due to the structural importance ofthese pieces, it's important that the newAn example of a poorly designed and fabricated subpenel truss that had failed in service, allowing the centerthrottle quodranllo move about liB· vertically.If ever there were two jobs made to be done together inBonanzas and Barons. it would be installing a new windshieldat the time a new instrument panel is being built. The panelproject is so much easier 10 do with Ihe windshieldremoved. We have certainly installed a lot of custom panels inBonanzas and Barons with the windshield in place, but cautionmust be taken to protect the windshield.The use of double layers of good masking paper workswell. But with the windshield masked off. you can no longer seeas well behind the ponel. so many access, clearance. checking.removal and installation tasks are just a lot more difficult.If you're able to. plan to do these two jobs at the same time.ABS September 2008 www.bonanzo.org Page 10938


Tempora ry support for the center throttle quadrantpanel be equal to the original in strength.Check out the picture of a homemadesubpanel that was poorly constructed andunder-designed to the point that it failedin service and, as you can guess. therewas no logbook entry for this bogusinstallation. That's just one example ofthings we can find when we disassemblea panel for something as relativelyunchallenging as painting it. No one eversaid this job would be boring'It is very important to support thelower subpanel structure during thepanel-building process. If not supported,the center quadrant will sag, result-ing in the two support subpanel piecesdropping toward the center of the panel.Keep an eye out for this phenomenon asyou look at custom panels; you willeventually find one with this ai lment.The not-so-high-tech solution tothis problem is cutting a genuine "FAAapproved"I" x 2" piece of wood andsecuring it between the floor structureand the base of the center quadrant. Thiswill support the entire lower panelstructure in its designed position as thepanel is being built.OUT WITH THE OLD ...Now it's finally time to remove theold panel overlay and fixed defroster.We do this with all the instrumentsinstalled and the radios removed fromtheir dust covers. Use an appropriatelysized drill bit and remove the mountingrivets around the perimeter of the paneloverlay and defroster. With these piecesremoved, you now have open access tothe instruments that are mounted on theshock-mounted subpanel. Be Slife to ragaI/wires alld lilies.Be very thorough about taping orcapping off all the pitot, static and pressurelines and fittings. And do the sameon the instruments, too. A little dirt goesa long way.Another tip: The original sixinstrumentcluster contains some verydelicate irreplaceable fuel-quantity temperatureand pressure gauges. Protectthe faces of these obsolete and veryvaluable instruments immediately witha piece of stiff cardboard.If you're dealing with a very earlyBonanza with a mercury vapor oil temperaturegauge, be sure to temporarilysecure the instrument to protect the verydelicate and small-diameter coppervapor line. These old gauges can beexpensive to repair.Properly protected engine and fuel gouges... . BUT SAVE THE PARTSIf you plan to replace these unitswith modem equivalents, make sure tosave the old ones. They could bringgood money on eBay, and you are helpingyourself and another old Bonanzaowner by making these treasures available.We save these coveted pieces forour in-house projects. We won't chargeour customers for these often pricelesscomponents as we've inherited themfrom previous projects.Having these parts allows us towork on these old panels. Sometimesjust painting a panel can cause an oldinstrument to fail, and our on-handstock can save the day.With the instruments removed andsafely stored, it is time to remove the oldshock-mounted instrument panel, shockmountingbrackets, battery box, old insu-All the old stuff removedOur hIgh-tech circuit protection device.Page 10939www.bononzo.orgABS September 2008

POWERPLANT lll :MAKING METAL?The most crucial aspect ofengine-condition monitoring isto ensure that nothing is comingapart inside the crankcase. Areyou sure that you and your A&Pare doing it right?Ihad been working with a Bonanzaowner in Memph is for severalweeks, helping him chase down aproblem with his Lycoming engine. Yes,Lycoming-the aircraft was an A36with a Machen conversion to a 350-hpLycoming TJO-540-J2BD engine. Theowner initially reponed that the enginehad exhibited several episodes of roughrunning after stanup, but that it seemedto run smoothl y once it warmed up.The owner e-mai led me a datadump from his JPI engine monitor,which confirmed my suspicion that his" morning sickness" was caused by acouple of sticky exhaust val ves in cylinders#4 and #5 . This is a fairly commonmalady in Lycomings, which is whyLycoming Service Bulletin 388C andService lnstruction 1481 A call fordoing a "valve wobble test" every 400or 1,000 hours (depending on what kindof exhaust valve guides are installed).The owner wound up taking hissick engi ne to John Jewell Aircraft, anexcellent engine shop in Holly Springs,Mississippi Gust southeast ofMemphis). Jewell pu lled the rocker cov-ers and fou nd the #4 exhaust val vesprings bl ack with carbon from a badlyleaking exhaust valve guide; #5 had thesame problem, but not quite as bad.But this anicle isn't about stickyvalves. It's about something much moreserious.Flying nozzleJewell inspected the cam to makesure it was not damaged by the valvestickingepisodes . In a Lycoming(unlike a Continental), you can'tremove the lifters from the outside ofthe engine, so the only way to inspectthe cam is to pull a j ug.Jewell proceeded to pull cylinder#4, and it turned out to be a lucky thingthey did. The ow ner em ailed me:"They found evidence of damage froma screw hommering the bonom of the piston.They olso found morks on thecrankcase on one side of the cylinderbose. The engine was removed and torndown. They found that the #1 cylinder oilspray noule and its helicoil hod corne out,bounced around inside the engine forsome indeterminate period of time, managedto hit all six pistons, and scored twoconnecting rod end cops."What is strange is there was no indicationof this in the oil analysis or any evidencewhen we cut open the oil filter ateach oil change. However, when I took yourmaintenance seminar in Tulsa a fewmonths ago, I learned that Lycomingengines have on oil pickup screen that yousaid is supposed to be removed andinspected for metal at every oil change. Itwas this screen that caught the metal fromthe disintegrating oil spray nozzle and itshelicoil, which is why the metal nevermode it to the filter."I checked with the shop that does myoil changes, and they admined that theydidn't know about the oil screen-they'remoslly Continental dudes. I didn't knowabout this screen (until I took your recentcloss), so I didn't remove it either. After this,I will never forget it, and I'll make sure myA&Ps don't forget it."The inside of the engine, althoughmarked by the flying noule, was extremelyclean. The crankcase has to be repairedand certified as well as the camshaft, lillieevidence of rust was detected on the lifters.All pistons and cylinders will be replaced.The turbocharger will also be overhauled. Itlooks like I'll be down for a couple ofmonths. When I get the plane bock, I'llneed flying lessons again.Here's whal's lett of the Lycoming's flying oil nozzle.The particles were too big to pass through the oilpickup screen, so they were never spoHed duringregular oil filler inspections.This lycoming piston was damaged by the flying oil nozzle. All six pistons, MO connecting rod cops and theinside of the crankcase were damaged.


"I wonder how much longer it wouldhave token for this to couse a catastrophicengine failure. I believe monitoring theengine helped find this. but clearly it wouldhave been found much. much earlier hodwe been inspecting the pickup screen on aregular basis:Monitoring for metalThe oi l system of any piston aircraftengine provides two levels of filtration.There's a relat ively coarsescreen at the oil pickup tube to catchlarge chunks of metal before they canget to the oil pump (and possibly damageit). Then there's either a fine oilscreen or a full-flow oil filter after theoil pump to catch tiny pieces of metalbefore they can get to the engine's bearings(and possibly contaminate them).When implementing a comprehensiveengine condition-monitoring program,it's crucial to understand thatthere are three distinct sizes of metalparticles we are looking for:Large particles or flakes that cannotpass through the oil pickup screen.Tiny particles that are too small to becaught by the pickup screen and gettrapped in the oil filter.Microscopic particles that are toosmall to be trapped by the oil filter.Therefore, our condition-monitoringprogram must comprise three distinctelements:I. Since microscopic particles aretoo small to be trapped by the oi l filter(and too small to see with the naked eyeeven if some were trapped), we mustplace the engine on a spectrographic oilanalysisprogram to detect abnormalwear events that throw off such particles.An oil sample should be captured atevery oil change and sent to the lab foranalysis. I recommend AviationLaboratories in Houston, Texas(hnp:llwww.avlab.com). and BlackstoneLaboratories in Ft. Wayne, Indiana(http://www.blackstone-Iabs.com).2. To detect tiny particles, wemust remove and cut open the oil filterat every oil change. Tiny particles canbe hard to see, so it's essential to cut thefilter media off its spool, spread it outflat, and carefully inspect each pleatunder a bright light (and preferably witha magnifying glass). For engines thathave only a fine oil screen instead of aspin-on full-flow oil filter, I stronglyrecommend adding a full-flow filterbecause it does a far better job of protectingthe engine and provides a farbetter means for detecting problemsbefore they cause a lot of damage.3. To detect large particles orflakes, we cannot rely on filter inspectionor oil analysis, because large stuffnever makes it to the filter or into thesample jar. For Lycoming engines, wemust remove and inspect the oil pickupscreen at eve,)' oil change. As we'veseen, this step is often neglected and,shockingly, some A&Ps don't evenknow about it!Unfortunately, TCM engines do notpermit the oil pickup screen to beremoved and inspected. (To gain accessto the screen you must drop the oil pan,something that usually can't be donewhile the engine is mounted in the aircraft.)So for TCM engines, about thebest we can do is (I) drain the oilthrough a piece of window screen orcheesecloth and then inspect it for anylarge panicles or flakes of metal; and(2) run a magnetic pickup tool around inthe oi l drain bucket and see if it picks upany pieces of ferrous metal. (This isn't abad idea for Lycomings, too.)Alas, very few A&Ps or aircraftowners perfoml these steps. The resultis that the worst engine problems-theones that throw off large chunks orflakes of metal-often go undetecteduntil it's too late. There's no excuse forthis if we're doing our condition-monitoringjob correctly.If you do your own oil changes,make absolutely sure that you'reIf there 's something like this f100ting around insideyour engine. you really want to know about it!Running a mechanic's magnetic pickup toolaround in the drained oil is a good ideo for anyengine, but particularty for TeM engines where theoil pickup screen cannot be inspected.inspecting the oil pickup screen if yourengi ne is a Lycoming, and that you'rechecking the drained oil for metal(using a screen and a magnet) if yourengine is a Continental.

This is the story of one of my stupidmistakes, and I certainly learned fromit. I hope others can benefit fromthis if only to reinforce what theyalready know.Show me someone who has neverdone anything stupid and I'll show yousomeone who has never done anything.My "old man" used to say, "I hope I canlearn from the mistakes of othersbecause I won't live long enough tomake all the mistakes myself."Well, I made a zinger of a stupidmistake when flying my TwinComanche. the plane I owned before mycurrent F33A.Knowing the reputation of PA-30s Iconsoled myself that my airplane was alot safer than others, with the extrapower of Miller mods and the betterhandling of Robertson STOL.After an excellent meeting in SanDiego and a great visit with my daughter,my wife and I were ready to roll onMontgomery Field's Runway 28L.To understand what happened next,note my propellers would not synch upat full duottle. This is in spite of fairlyrecent overhauls. So after takeoff andreaching 400' or 500' above groundlevel, I usually gave the prop controls alittle tweak to eliminate the annoyingbeat from the asynchronous props. Noproblem! Heck, I've been doing this fora long time. Right? o. not necessarily.Back on the runway, we werecleared for takeoff. I watched thegauges as the throttles advanced andeverything was OK. We started downthe center line. But just as we started tolift off, the pilot (who would rather notuse the first-person pronoun here)decided to adjust the props. Seemed likea good idea at the time. But it was not.That airplane veered right, thenbanged back on the ground and veeredleft off the runway faster than you couldbelieve! At this point it was chop thepower, hold on and steer clear of anythingbad.The bad in this case was an airplaneon taxiway D. The reason I rememberthat is because the lesser bad was a taxiwaysign with a big D on it. So it was aninstant choice: Take out the sign or takeout the plane?We zoomed through the muddyfield, tore out the sign. shot across thetaxiway in front of the startled Cherokeepilot and rolled to a stop, having dissipated75 to 85 mph.WHRT HRPPENED?As the plane stopped, the rightengine was idling normally, oblivious tothe excitement and scare. The leftengine was shut down with the propfeathered. The left propeller control wasfull aft.I' ve done a bit of soul searching andoffered a few prayers since this experience.Apparently, as I anempted to syncthe props at the moment of rotation, theleft control was inadvertently pulled allthe way back. It happened so fast I didn'tnotice the lurch to the right caused bythe pitch change of the left prop. Mywife felt herself being strongly lurchedto the left as the plane veered right. Andthis lurch caused my hand on the propcontrol to come all the way back, featheringthe left prop.But the real reason is: It was a stupidthing to do. And this comes from a pilotwith more than 1,600 hours-330 in aCessna 195 and almost 500 in the TwinComanche before moving into an F33A.Along with a huge dose of humilitycame a renewed respect for flying and acouple of real object lessons:J Ie 11col' a a ntl I tin nl rexI

Swing isworse at higher rpm. Does not seem tobe sensitive to load or any of thestrobelbeacon circuits. The battery is anew Concorde RG-24-15 installedunder a Wilco STC. There is a very softwhine in the headsets (Gannin 530 withBose ANR sets) that follows the swingand rpm changes in pitCh and intensit y.We have changed the alternatorsw itchlbreaker assembly to the newer -73 PIN. We found and cleaned somecorrosion in the battery ground circuit.Static checks through the chasging systemseem 0 K. 1 do not want to justthrow parts at this. Is there any way thebattery could be causing this swing?The owner claims the problemstarted after the battery was installed.Otherwise 1 would not think the alternatoritself would run up and down, whichleaves the controller or maybe a faultynew switch as the culprit.A: It sounds like you may have a badrectifier diode in the alternator causingthat section to produce AC instead ofDC. This will produce the whine, whichfollows the throttle, and also wi ll causethe ammeter to oscillate.I cannot think of any reason whythe battery would be at fault unless therehappens to be a weak or bad cell.

It wasn't bad, so 1 took offand the vibration continued for about 3seconds, then stopped. 1 didn't feel anythingbefore 1 reached 65 kts and didn'tfeel anything upon landing. Could thisbe the shimmy dampener, and if so, isthat something an owner can service?A: What you describe is usuallycaused by a nose wheel tire/wheel out ofbalance. I f the tire is not abnonnallyworn, it can be statically balanced usingautomotive stick-on weights to achievea balanced condition. Also check thenose gear torque links for excessive freeplay and the shimmy dampener forfluid.These checks are items an ownercan complete, but when it comes to thecorrective action, you will need to havea mechanic do the work or superviseyour work for sign-off. (And as always,others may have a different opinion asto what an owner can do.) - AMSpark plugsJoe King, Bakersfield, CaliforniaQ: I need a spark-plug change on anon-turbo'd 10-520. What does ABSrecommend: Standard or Iridium? Costis not a factor if compensated by otheradvantages.A: If we use Champion spark plugsas a popular example, we find anIridium RHB-32S fi ne-wire plug at$74.25 vs. a RHB-32E massive electrodeat $21.75 (Spruce). The Iridiumwill not last three and one-half timeslonger than the massive, and with equalmagneto and plug wire condition, theperfonnance difference is not usuallydetectable.


With that said, I run lridiums. Theirplug life can be greatly extended if theperson doing the abrasive cleaning wiIIdo so at 55-60 psi and 1101 at the normalshop air pressure of 120 psi. Speak toyour mechanic about this if you are running"precious-metal" plugs. -BACurly cordsJeffrey Stultz, Zionsville, IndianaQ: I have a 1968 E33A.

He asked me to find out ifthis is permissible (he could not find thedata in his manual) and what if any, arethe limits for movement. Also, if theyneed to be replaced, where can 1 go forreplacement parts?A: There should be no play in the ruddervatorpush rods. There is a rod endbearing on each end of the push rod. Thepart number for all four is MD46-15. 1suggest replacing all four as long as youhave the rod out of the aircraft.Pay close anention to the overalllength before you remove the old rodend bearings as this length is critical tothe rigging of the ruddervators.Parts can be obtained from anyBeech parts supplier such as ElliotAviation (800-978-7253) or fromRAPID (888-727-4344), where you canuse your ASS Visa for parts discount.- BRCowl flap actuatorsKen Clark.

When we came torefit the senders, they would not workand showed no resistance whenchecked. I sent them to John Wolf forrepair. We wired up the repaired sendersand established that the gauge in the aircraftwas working as it should. We thenrefitted the senders.With the aircraft back in service,the tank showed a full indication untilthe level fell to about one-quarter, whenthe gauge would move from full to quarter-fullwith no intermediate reading. Itolerated this until the plane was in formajor maintenance a few months ago.We removed the senders and determinedthat the inboard sender was"earthing out" (grounding) on the tank.We refined and the tank level readexactly as it should - for 28 days. At thattime, I filled the tank and found thegauge showed only a quarter full. I tookthe plane in to check thi s out, suspectingthat one of the senders may be earthingout. However, we have rechecked thefining, which is as it should be, but cannotmake the senders give any sensiblereading on the gauge.Do you have any ideas? Could thewiring be wrong? I am returning thesenders to John Wolf to check them out.My engineer believes that whilst there isa variable resistance on one of these nder wires, there is nothing on theother wire. (I may be describing thisincorrectly because I have no electricalknowledge at all!)A: If the inboard sender contacts theaircraft surface, it will ground and causeimproper readings. The outboard sendershould be grounded to the aircraft witha bonding jumper. One wire from theoutboard sender connects to tertninal #4on the inboard sender. Wire #Q6A 18connects to terminal # I on the inboardsender, and wire #Q4C 18 connects toterminal #2 on the inboard sender.

NBARON CHARGING SYSTEMS - The Baron chargingsystem went through an evaluation process with at least threedefined generations. The first had generators. Then there wereoptional alternators from the factory and third came aftermarketalternators. There were also factory alternators with variationsas standard equipment.When troubleshooting, make sure you know which systemyou are deal ing with, and have the correct wiring diagram,The difference can throw you off when deciding where youshould have power or grounds.Recent testing was done on a Baron that had no chargingon one side. It was correctly suggested by one of the ABStechs to add a good ground from the alternator to the airframe.When it still did not work, the tech suggested the membercheck (with the engine not running, and the master switch on)for voltage at both the field wire (small) and the output wire(large).When there is no power at the output terminal it meansthere is an "open" between the alternator and the buss. In thi scase it was a 50-amp circuit breaker that had not popped theindicator button but which had popped open internally. Pullingand resetting the breaker solved the problem.Over-voltage disconnects on single-engine models cansometimes be reset by turning off the master and alternatorswitches for a minute or two and resetting. This is difficult infMC. Earlier Barons can usually be switched to the other regulatorsince they only use one regulator at a time for bothalternators.Imbalanced loads on Baron alternators many times aredue to differences in the resistance in the circuits while receivingthe same level of excitation from the regulator.Voltmeters are still the most useful instrument in monitoringor troubleshooting alternators. Generators on the earlyBarons, "Delcos," regulate the grounds ide of the field.

Remember when refilling with oilthat it should only cover the gear contact areas. The box shouldnot be completely fi lled. The filler plug is a vent and should beclear. Oi l dripping from the hand crank is usually due 10 thegearbox being overfilled or a solid plug having been put in thefiller hole.E-SERIES ENGINE PROPELLERS - Lew Gage's book fromthe ABS Store is an outstanding reference on many areas of theearly Bonanzas, including propellers. The type certificate datasheet (TCDS) on the FAA website (www.faa.gov) is a goodreference, but you need to look at airframe, engine and propellerTCDSs to get all the information, including rpm limitsfor the various combinations. Most of us agree that the 2 I 5 isa better prop and that running them in manual causes less wearthan operating in automatic.If you have the Hanzell propeller or are looking to buy aHanzell, become educated about which model hubs haverecurrent Airwonhiness Directive inspections. Hanzell investedits own capital in the redesign and sold them at a reducedprice for an extended period of time. Now they charge what itreally costs to produce, and a new Hartzell for an E-engine isvery expensive.@Page 10949 www.bonanza.org ABS September 2008


FAA INFORMATIONAD 2008-14-07-INSPECTION AND REPLACEMENT OF FUEL-INJECTION LINESThe FAA has issued AD 2008-14-07. colling for inspectionand replacement as necessary of fuel-injection lines. This AD.which affects 10-360-B1 B engines installed on fuel-injected TravelAirs. supersedes AD 2002-26-01 . It contains the some compliancerequirements as the eorlier AD but odds to the list of affectedengine models.Travel Airs thai are in compliance with 2002-26-01 arealready in compliance with the new AO_ but owners should updatethe AD record for their aircrafl to reflect the new AD number.See AD 2008-14-07 for compliance criteria.The FAA in July 2008 issued aSpecial Airworthiness Information Bulletin(SAl B) suggesting repetitive inspection ofSlick (Unison) magnetos.From the SAIB:There have been field reports of prematurewear of the corban brushes in acertain serial number range of magnetos.Premature brush wear could lead to failureof the magneto to provide consistentspork. which could result in possible lossof engine power.The actions required by UnisonIndustries Service Bulletin SB3-08 do notprovide a solution or terminating action. Theactions specified in the SB are intended todetect signs of wear before damage grows.which could result in magneto failure.The service bulletin will be updatedwhen terminating action is implementedby Unison. Meanwhile. the SB inspectionrequirements will remain in effect.SAIB CE-08-33-REPETITIVE INSPECTION OF SLICK (UNISON) MAGNETOSThere may be additional inspectionrequirements or other corrective actionsdefined by your respective engine and aircraftmanufacturer's service informationconcerning this service difficulty issue.At this time. this airworthiness concernis not considered on unsafe conditionthat would warrant on airworthiness directive.The FAA recommends compliancewith Unison Industries Service BulletinSB3-08 as follows:- Magnetos with serial numbers0409XXXX through 0611 XXXX. and all(Slick] magnetos that have hod a corbanbrush or distributor block replaced betweenSeptember 1. 2004. and November 30.2006. should be inspected at 250-hourintervals. Affected magnetos with over 250hours since new or distributor blockreplacement should be inspected within50 additional operating hours and at 250hours in service thereafter.• Magnetos with serial numbers0612XXXX and up and all magnetos thathave hod a carbon brush or distributorblock replaced on or after December 1.2006. with less than 50 hours in serviceshould be inspected within 5 additionaloperating hours and then reinspected at15 to 20 operating hours until reaching 50hours in service. Afterword. and for allaffected magnetos with more than 50hours in service. the requirements for serialnumbers 0409XXXX through 0611 XXXX(first bullet point) apply.The FAA issues SAIBs when operationalexperience shows a trend that doesnot meet FAA criteria for issuing on airworthinessdirective. Compliance with SAIBs isvoluntary but recommended.For detOils and specific inspectionrequirements. see FAA SAIB CE-08-33 andUnison Service Bulletin SB3-08. @ABS September 2008www.bononzo.orgPage 10950


BARON SINGLE-ENGINEPROCEDUREBY CRAIG KERN, DAYTON, OHIOYOU are estab lished on the lLS to your home field andweather is at minimums, You are inside the finalapproach fix. gear down, approach flaps, airspeedwhere it should be and the needles centered,As you approach the decision altitude (DA), you notice,in your scan, the clouds appear a little thicker than before youstaned the approach, Sure enough, the run way environmentdoes not emerge at DA so you execute a missed approach:Power up, pitch up and clean up,As you pitch up, you notice the aircraft yaws to one sideand doesn't seem to climb as it should, You immediately tumback to the heading bug that you set on the runway headingand realize you've lost an engine, You then pitch down toestablish Vyse (blue line) and immediately stan to clean upthe aircraft It is very important to accomplish this in an expeditiousmanner since your climb performance is seriouslydegraded, Even after you clean up the aircraft, you have lostapproximately 81 % of your climb performance,During a normal climb, under some conditions, manyBarons can be expected to achieve a 1,525 fpm rate of climbat a twin engine Vy of 107 knots, With one engine shut downand feathered, the same aircraft, under the same conditions,might only achieve a 290 fpm rate of climb at a Vyse speedof 100 knots,The Baron Pilot'S Operating Handbook states that continuedflight requires immediate pilot response to the followingprocedures:Mixtures full forwardPropellers full forwardThrottles full forwardFlaps up• Gear up• Identify inoperative engine, idle foot, idle engine• Verify illoperative ellgille (Reduce throttle onsuspected dead engine. If there is no changein control inputs or sounds, you have correctlyidentified the inoperative engine,)Propeller lever of inoperative engine; featherWhy clean up in this order?We want to get rid of the drag items as quickly as possible.If you remember performing a drag demonstration (eitherduring your training or at a BPPP clinic), you found out thatthe landing gear causes about 400 fpm degradation in performance;fl aps cause about 400 fpm degradation and a wi ndmillingpropeller causes about 800-900 fpm degradation,Therefore, until we get the propeller feathered, we are unableto climb (or even fly level), However, one doesn't want tofeather an engine that isn't properly identified. as there is apossibility of choosing the wrong one,After feathering the engine and controlling the airplane,you explain your plight to ATC, ask for either the sameapproach again or to go to yo ur alternate (given the weatherscenario, an airport with better weather should be considered),Once you are safely at an altitude. you can incorporaterudder trim to relieve the pressure on your leg and thenaccomplish the rest of the engine securing checklist (mixture,fuel selector, fuel boost pump, magneto switch, alternatorswitch, cowl flap), Now you can concentrate on flying youraircraft for a successful single-engine approach,Once you have decided on a course of action, BPPP recommendsthat you neutralize the rudder Dim (that is, set it to 0degrees), outside the final approach fix, You will have to maintaina rudder pressure toward the live engine while you have itpowered up, but the rudder pressure will decrea e as youdecrease power on the operating engine close to the runway,Interestingly, as you retard the throttle on the operatingengine to idle, you will actually have to apply rudder pressuretoward the inoperative engi ne, This is because the windmillingengine will create more drag than the dead enginewith the feathered propeller.Before your next night, take a few moments to reviewthe Engine Failure after Lift-off Checklist to make sure youknow the proper procedures for fl ying the airplane and securingthe failed engine.

ELECTRICAL PROBLEMSIn this month's column I am covering some commonelectrical problems that ABS members have askedme about over the years.Troubleshooting fuel gauge(s)& associated components.Warning: First, an important caulion is in order. The electricalsystem has changed so many times over the years, oftenwithin model years, that allY specific advice 1I1lISr be based 011rhe serialllulIlber of rhe aircraft. There are different theoriesof circuit operation as well as wiring interconnection that mustbe understood to troubleshoot a problem. J found 19 differentfuel gauge circuits just for the V-tails, with a slightly lowernumber for other models.Documentation: Beech has documented the wiring diagramsin the shop manuals for the early models, and in separatewiring diagram manuals after 1975. All the wires that camefrom the factory have identifying numbers in the followingformat: FNNWZZS where F is a letter identifying the circuitfunction area, NN is the circuit number, W is the wire segment,ZZ is the wire size and S is the suffix.An example of a wire in the fuel gauge circuit for my1968 V35A D8663 is Q8A18. Q is the designator for fuel andoil circuits, the circuit number is 8, the wire segment is A andthe wire size is 18. There is no suffix.With the proper wiring diagram handy, one can locate thewire, even if it is in a bundle, and know exactly what it shou ldattach to if you refer to the wiring diagram. So if you disconnecta wire and don't mark it, all is not lost.Fuel gauge circuits: There are three types of fuel gauge circuitsfound in the Bonanza, Baron and Travel Air. But not allvariations are covered in these descriptions. I have discussedthe most common systems, so you need to verify rhe specificwirillg diagram for your aircraft before you jump imo lroubleshoolillgIhe syslem.Common to all systems, good connections-especially toground-is important and should always be checked.Early systems: The early systems are based on a resistivepotentiometer-like transmitter that is wired to a gauge thatreads current through the transmitter-the higher the current,the lower the indication. Most of the transmitters are of the 30-ohm variety. When the tank is full, the transtttitter will read 30ohms to ground. When the tank is empty, the transmitter willread close to zero ohms.On aircraft with aux tanks, there is usually a switch toselect the tank indicating on the gauge and some of the earliestaircraft share a single gauge with the left and right tanks.Some of the aux tanks have two transmitters that are wired inseries. For dual transmitters, each is about 15 ohms, adding to30 ohms when full and zero ohms when empty.To troubleshoot the system, remove the inspection panelabove the fuel transmitter. Remove the wire from the transmitterthat goes to the gauge. The gauge should read over full.If you short the wire to ground, it should read empty.The fuel transmitter should read 30 ohms when full andzero when empty. You can purchase a 30- to 50-ohm wirewoundpotentiometer and connect it to the wire going to thegauge and vary the resistance between 0 and 30 ohms to checkgauge calibration. At 15 ohms thegauge should read half. At 7.5 ohmsthe gauge should read 1/4, and at22.5 ohms it should read 3/4.To be within specification, thegauge needle should touch any partof the E mark when empty and anypan of the F mark when full.The only adjustment in thesystem is by bending the arm on~.-... the fuel transmitter to obtain a betterresult.1. au.. bar2. ruel quantity indicator drcult b"aker3, Fuel qua.ntlty Indicator4.

The transmitters

Onegauge movement coil pulls theneedle toward the full positionand the other pu lls it towardthe empty position.The gauge-full positioncoil is attached to 12 vo ltsthrough a circuit breake r.

Therefore the gauge indicates empty.When the voltage output from the transmitter is at 6 volts,the current is the same in both the fu ll position coil and theempty position coi l because they both have 6 volts acrossthem. Therefore the needle indicates half full (or half empty ifyou are a pessimist).There are two vintages of transmitters and they can beintermixed. The original transmitters have four studs(i nboard) and two studs (outboard). The replacementtl'Onsmittel'Shave two studs (inboard) and one srud (outboard).To troubleshoot the system, remove the inspection panelabove the inboard fuel transminer. With the master switch on,verify that you have + 12 vo lts on srud #2 of the transminer.1EMPTYSrud #1 has the wire that goes to the gauge. If you removethe wire fro m stud #1 (open), the gauge should read half-scale.If you ground the wire terminal lug, the gauge should read full.If you touch the tenni nal lug to the #2 stud (+ 12 vo lts), thegauge should read empty. Turn off the master switch. If YOllrgallge doesn't read proper/y, have it overhallied.The inboard fuel transmitter case should be isolated fromground by a felt washer (Figure 3). If it is not, the gauge willread full until the acrual fuel level is close to 2/3 and then WIllmove the rest of the way faster than the change in the fuellevel , although it will read correctly when the tank is empty.Remove the wire attached to the case and that connects tothe outbound fuel transmitter. Verify that the case is not grounded.If the case is grounded, reseat or replace the felt washer.


With the wire from #1 stud and the case still removed, theresistance between the #2 stud and the case should be around76 ohms. The transmitter wiper (stud #1) should vary betweenthe full resistance value (when empty) and zero, reaching zerowell before being topped off (around 2/3).The outbound fuel transmitter measured between post #4and the case should be about 43 ohms when empty and zerowhen full.1 97O-and-after modelsThe later 40-gallon systems use dual transmitters in serieswith one another. There is only a single post for the wiper andthe case is the other terminal. The inboard transmitter is 76 ohmsand the outboard transmitter is 43 ohms. The transmitters read119 ohms added together when full and zero when empty.Each side's transmitters are attached to a printed circuit. module mounted above the fuel gauges under the angle mountfor the glareshield suppon (Figure 4). On the rear lefthand sideof each module is a slotted adjustment that allows the full indicationto be adjusted on the indicator.If the gauge becomes flaky and bounces around or is completelydead, it is often the printed circuit module. It is relativelyeasy to swap the connectors on the back of the left andright modules to help isolate the problem module. If the faultgoes with the module, it is time to send it Ollt for repair. BirksAviation Products (309-686-0614) rebuilds and exchangesthese modules for a flat $430. Birks advenises in the classified-adsection of the ABS Magazille.The fuel gauge should read the following values +/- 2 mvacross the gauge terminals for the respective fuel load of 114,112,3/4 and full: 36 mv, 60 mv, 86 mv and 103 mv. For empty,the gauge should read 6 mv +/- I mv.The inboard fuel transmitter has one post that connects tothe printed circuit module (Figure 5). The case is the other terminaland is attached to the outboard transmitter. The circuit iscompleted by the outboard transmitter, which is grounded to theairframe.The inboard fuel transmitter has a felt washer under thecase to isolate it from ground. If this is missing, the case will begrounded and the tank will never read above 2/3. If the outboardtransmitter is shoned internally, it will cause the same symptom.You can troubleshoot the transmitters by removing theinspection panel s. Remove the wires attached to both thetransmitter posts and make sure the outboard wire is notgrounded to the airframe or you will get a false ground readingon the case of the inboard transmitter.

emoved from the inboard ruel transmitter, the gauge shouldread above full. With the wire shorted to ground, the gaugeshould read empty.When the tanks are full , measure the resistance of theinboard transmitter from the post to the case and verify it is closeto 76 ohms. Verify the case is nOt shorted to ground; if it is, verifythe felt washer is installed and isolating the case from ground.Verify the outboard transmitter is close to 43 ohms, postto ground. If you remove the transmitters, they shouldsmoothly vary in resistance between zero and the maximumvalue as they are moved through the float arm range.If one or both of the fuel transmitters or a gauge needs tobe overhauled, Airparts of Lock Haven (1-800-443-3117 -http://airpartsofiockhaven.comJ) is one company that can performthe overhaul. There are other companies that provide thesame service.In fLllUre colLlmns, I will offer troLlbleshooting tips for electrolLlminoLlspanels (EL panels) and false altemator-oLlt indications.John Collins.

Johnowned and operated an FBO. with a vionics shop, for six years.AVIONICS Q&AABS MEMBERS SEEK ANSWERS FROM JOHN COLLINS TO THEIR AVIONICS QUESTIONSJAMES DEVANY, Joyce, WA, isinstalling a KLN-94 with an NSD 360for IFR operations in his G35. Heexplains that he has had a VFR KLN-89prior to this. His question:Do you know of an STC I can useas a reference on the POH supplement?Or is a better plan to get a FieldApproval for POH and FAA Form 337purposes?COLLINS: All the information youneed is avai lable free on the HoneywellBendix-King website, but you need tohave your dealer download it. My dealerwill do it free when the documentsare on their website and are available forfree download, as is the case for you.Your local dealer should also be able toget it for you free. Ask for a copy of thelatest install manual that has an appendixwith the Sample AFMS and it referencesan STC on a Mooney.Follow any of the relevant instructionsin the install manual for an IFRinstallation. Then your avionics shop orIA can approve the installation andreturn the aircraft to service with a logbookentry, a placard stating the GPS isVFR on ly and an appropriate 337 forthe installation.You will need to modify the AFMSfrom the install manual to match yourinstallation and submit it with a separate337 to your FSDO requesting a fieldapproval. Once it is returned, you canremove the VFR-only placard and replaceit with one called OUt in the manual.The shop or the lA returns the aircraftto service for IFR by signing thefield-approved 337.MICHAEL LEBLANC, Orangeville,CA, noticed on the May 2008 ABSMaga:ine cover that Jim Greene had tiptanks installed on his Bonanza and mentionedhe had an S-Tec 30 autopilotinstalled. He says:I was told by my avionics peoplethat S-Tec would not allow their autopilotsto be installed in a Bonanzaequipped with tip tanks. Could you shedsome light on this? I would really like toupgrade my 1952 C35 with this newerautopilot.COLLINS: My understanding is thatthe S-Tec's STC hasn't been tested withtip tanks. Often the autopilot is installedbefore tips are added. It is up to the lAwho signs off the tip tank installation toverify there are no conflicts.Not all avionics shops will care orcheck if there is an issue installing anautopilot if there are tip tanks. I personallyam aware of numerous aircraft withboth tips and S-Tec autopilots. I haven'tchecked into it, but my guess is thesame would be true for Bendix-King,Century and Garmin.JEFFREY QUIN, Camarillo, CA,installed a new JPI EDM 760 last yearin his 1977 95-B55 and reports that he isstill having prOblems with the Garmin400 interface. He says:Using takeoff power, the RS-232interface between the EDM 760 andGPS 400 goes down. The JPI unit hasthe memory stick download. I assumethe higher ruel flow causes the issue.When power is reduced to a cruise setting,the interface starts working again.I used a loaner unit with the standarddownload interface (not a USB)and this unit worked without a problem.The avionics shop checked the Gartninunit and reported that all was well.Have you heard of anyone reportingthis problem with a Baron? JPI tellsmy shop (Cruiseair in Ramona) that noone else has reported the problem,although the users with the memorystickinterface seem to be mainlyBonanzas.COLLINS: I have not heard of thisbefore, but based on the fact that theserial interface worked as advertisedwith the loaner unit, I would request awarranty replacement from JPI. If theproblem continued, then JPI has adesign issue. But I suspect a replacementunit will solve the problem.@


CIRCUIT BREAKERAD 2008-13-1 7BY CHARLES HAR~SO[\j. SARASOTA. F'ORIDAIwas aware that the circuit breaker AD (2008-13-17) waslurking in the background, but when I received the noticevia the FAA automatic Airworthiness Directive distributionwebsite, it was an unwelcome surprise. J suspect most of youwill deliver your bird to a trusted shop to accomplish the AD.1 am fortunate to have an A&P who supervises my work andis helping me prepare for A&P certification, so it wi ll becomea learning experience for me.The AD cites Hawker 8eechcraft Service 8ulletins S8-24-3735 and S8-24,3807. J went to the A8S website, whichrejected my log-in (a problem since resolved), so I calledHawker 8eechcraft at the telephone number listed in the AD,The first contact indicated that the company was not planningto provide kits of the required replacement parts by aircraftserial number, which meant 1 would have to order by part numbers.So I was transferred to tech support where Sarah 8all wasmost helpful. She e-mailed both bulletins within the hour.S8-24-3807 deals only with the G58. S8-24-3735 spellsout a long list of models and serial numbers and provides across-reference between the original circuit breaker partnumber and the replacement part number. The AD and bothS8s are available on the A8S website.The learning begins. TheATP CD that I bought fromABS has the electrical wiring manual for my SSP. 1 started bymaking a computer spreadsheet of each circuit breaker andswitch located on the subpanel in the aircraft. Then I discoveredSection 24, Electrical Power Distribution, which detailsall the parts, including the affected circuit breakers.Remember, 1 said it was going to be a learning experience!There are several lists in Section 24, grouped by aircraftmodel and a range of serial numbers. Within the list for myserial number (TJ-150), there were a couple of circuit breakersthat have more than one part number listed. The right-handcolumn in the listing shows an applicability code number. Atthe end of the list-and in my case several pages away-wasa cross-reference between the applicability code and a subgroupof aircraft serial numbers.It was confusing at first, but it soon made sense, and I wasable to compile the list shown here for my aircraft.Stay tuned for how this turns out.

•AFT CABIN DRAFT R~ Ie A.LSHIDDEN CORROSIONTOM KENVILLE. HORACE. NORTH DAKOTAread with interest the July 2008 Tech Tips item from DavidCox titled "Hat-shelf draft." My 1972 Baron 58 has thesame cold atmosphere in the club-seating area. I have spentmore than $ I ,000 auempting 10 correct this problem.The aircraft is based in Fargo, Nonh Dakota, so we knowwhat cold really feels like. At 10,000' 10 12,000' this is a continuousproblem on days without direct sunlight. I feel that thereal issue in this case is the building of pressure in the rearbulkhead.I built an additional bulkhead in front of the rear luggagecompartment. While this improved the cabin appearance, itcreated an increase in low pressure in the rear luggage compartmentarea so the cold air coming forward actuallyincreased in volume and pressure, and got colder.This cold air travels between the outside skin of the Baronand the upholstery of the cabin. The passengers actuallythought the windows were leaking air, but it is the cold airbuilding pressure in the rear of the aircraft and coming forward.This pressure is more prominent on the port side. Thecargo doors on the starboard side block the cold air at the reardoorframe.I received FAA approval (337) to install an electric heaterin the rear of the Baron in place of the seat by the cargo door.There has not been much improvement, as the cold air surroundsthe passengers like a cold blanket.I installed an exhaust vent on the port side and a vent onthe rear cargo bulkhead. I have used this with and withoUlthetube for airflow, with liule or no success.I used aeronautical adhesive (duct tape) to cover the holeson the outside for the cut-outs in the rudder and elevator controlsurfaces, making sure the cables did nOl contact the tape.There was very liule improvement.It was suggested by the ABS technicians (after I had visitedthe technical folks at Beechcraft) that I should install anadditional Belly Scoop exhaust in the Baron's rear compartmentand I accomplished that at its last annual.When the A&P removed the floor panel, which is not partof a normal annual, he discovered corrosion-and that is themajor reason for writing to ABS.I am contemplating installing heated seats in the Baron(similar to those found in some vehicles). I'm very frustra!edwith the cold rear compartment of my Baron. As a last resort,1 intend to duct-tape the upholstery as ABS Tech Neil Pobanzsuggested in the July issue.The serious issue is the corrosion under the floor plate, ascan be seen in the photos. This corrosion problem may be afleetwide issue, since this panel is not removed under normalconditions or during annual inspections. @ABS September 2008 www.bononzo.org Page 10957


"There are f:hase wha halle ...and f:hose who won ' f: • .. -A new mantra:Landing gear-relatedmishaps (LGRMS)BY THOMAS P TURNER. ABS TECHNICAL SERVICES MANAGERAt the end of a long day as instructor in a new Beech Boron. my studentpilot and I were on a left downwind to Wichita Mid-Continent Airp ort inKansa s when I reached up and reduced throttle on the left engine to simulateon engine failure. As expected. the familiar "beep-beep-beep' of thelanding-gear warning horn sounded as the throttle moved toward idle.The drill was intended to have my student identify and secure the foiledengine and then land with the "dead' engine set at zero thrust. But in thisinstance. there was a catch. It was windy and turbulent.Turning bose and then final. the Boron's groundspeed slowed to a crowl.We were on about a ha lf-mile fina l when I realized that the student hod forgottento lower the landing gear- and I hod forgotten to check. The lowgroundspeed and turbulence resulting from the strong low-level winds conspiredto make airplane performance appear as if the gear was down.It can happen to anyoneAfter years of giving engine-outb'aining I was conditioned to ignore thegear warning horn, so that particularsafeguard did not hold my attention. Itwas fortunate for us that I realized theoversight in time. Since then, I have dramaticallychanged the way I teach landing-gearextension.If your training was similar tomine, your introduction to retractablegearairplanes consisted of three or fourlandings before you were sent off solo.However, the accident records show thata few times around the patch might notbe enough to prepare students to avoidgear-up landings.The "resignation" mindset"There are those who have, andthose who will." I'm sure you have oftenheard that remark when pilots talk aboutlanding retractable-gear airplanes withthe gear up. I think this statement is afine example of a "resignation" mindsetthat goes something like: "Oh, well, agear-up landing sometime is inevitable,and there's nothing we can do to avoidlanding gear-related mishaps."I suggest we learn a new mantra:"There are those who have ... alld thosewho \vOIl'I. "Unfortunately, landing gear-relatedmishaps (LGRMs) in retractable-gearairplanes are common. FAA preliminaryincident reports show that morethan half of aU accidents inVOlving pistonretracts are LGRMs. And they occuroften-as many as six or seven a week!Because they rarely cause inj ury orreportable damage (most LGRMs don'tmeet the requirements for a NationalTransportation Safety Board report orinvestigation), they seldom are reflectedin the statistics used to compute the general-aviationsafety record . This i sdespite the fact that the average cost ofrepairing an airplane involved in anLGRM runs over $60,000. And thoughthey rarely cau se injury, they frequently"total" the airplane because of repaircost and may render a pilot uninsurablefor up to fi ve years!LGRMS COME IN THREE TYPES:The "Oops. I forgot.' or classic gear-uplanding.The gear collapses on the landing roll. butnot because of any known mechanicalproblem . Chances are the squat switchfoiled when the pilot inodvertenlly put thegear switch in the up position. A side loadduring a too-vigorous turn may open thesquat switch momentarily. allowing thegear to retract. My research shows thatsquat switches do nat open until the airplanehas slowed nea rly to a stop on landingbut close early in the takeoff roll. Sothey won't protect against gear-switch activationfor most of a takeoff ar landing. andnot at all in a touch-and-go.The true mechanical fa ilure. in whichthere's nothing thai can be done from thecockpit to completely extend the gear.Historically, LGRMs are aboutevenly split between the first two scenarios,with a comparatively few truemechanical failures.In many cases, strong surfacewinds or other distractions (like doorsopening in flight or electrical fai lures)are contributing factors in the gear-uplanding. Gear collapses often resultwhen a pilot is in a hurry to clean up theairplane during the landing roll, orwhile performing a touch and go, andinadvertently moves the landing-gearhandle instead of the flap switch.How can we avoid thisall-too-common mishap?Simply being aware there is a hazard maymake pilots work harder to ovoid it.Spend more time on the retractable-gearcheckout. Take nme to introduce proper landingijearextension and verification discipline.and proctice it enough that the potternsbecome second nature. Perform the emergency-landing-gearextension procedure(using the checklist) as port of the checkout.Review the POH. Use a prelonding checklist(printed ondlor mnemonic) and reinforceusing it in the cockpit. Make sure you knowhow the gear system works and how tomanually extend the gear if it doesn't.Verifiy that the landing gear is down andalso confirm that the gear goes down andlocks. I like to hold onto the gear-extensionswitch as a reminder until I have the timePage 10958www.b o nanza.orgASS Se p tember 2008


to scan the down-ond-tocked indicotors.Many airptanes have externat rnirrors thatallow you to see when the gear is down.Deal with distractions during retractablegeartraining. Make sure you can rememberto lower the gear when other thingsintrude on your oHention. Dilen studentswill forget to extend the tanding gear duringpractice emergency tandings. Theymake the runway or emergency fietd in finefashion, only to be faced with on unfortunatesurprise at the end.Remember that on tanding, the pilot shoutdnot reconfigure the airplane until it comesto a complete stop. tn almost half of theLGRMs, the pitot inadvertently retracts thegear during the landing roll in the rush toclean up the airplane.Avoid touch-and-go practice in retractableoirplanes.A lot happens in a very short timeduring a touch and go, and many times thepilot inadvertently retracts the landing gear(instead of flops), causing a mishap. Makeall your landings full stop to reinforce thediscipline of stopping before reconfiguringthe airplane.If you're on instructor, don't try to conduct acheckout in on airplane with which you'renot completely familiar. Do yourself a favorby finding on instructor expert in a newairplane'soperation, if you're not familiar withthe type.Be vigilant. You're the lost line of defense inavoiding a gear-related occident.LGRMs put pilots at physical andfinancial ri sk_ They remove good airplanesfrom the active inventory andresult in increased insurance cost asunderwriters pay to repair airplanes.

Use youpchecklistsR':~N FROM THE 0 ,PTEMBER 2aJ5 ABS MAGAZINEBY JOHN M MILLER. POUGHKEEPSIE. NEW YORKWhen you get into your car to drive somewhere, youjust turn the key and go. Yes, you might look atthe fue l gauge, but that is about all. It seems thatsame procedure is infecting some general-aviation pilots inrelation to flying their airplanes.One very cold day in winter I happened to see a pilotremove the tiedowns on his airplane and. without even lookinginto the fuel tanks, jump aboard, start the engine and instantly,wi thout bothering to warm up the engine, run it practically fu llpower to get moving in the snow to the taxyway. He taxied tothe takeoff end of the runway and took off.An accidem did not happen, but the incident got me reminiscingabout the olden days of flying, when checklists wereso rare there was not even a name for them.I remember when I was flying for UAL in 1936, wordcame to us that TWA and PAA were using takeoff and landingchecklists and that we were going to be required to use themalso. Some of the older pilots grumbled when it was required,but Walt Addems, the chief pi lot at Chicago, insisted that achecklist he supplied be used. After all, the new Boeing247-D, the fIrst modern airliner-the first to have a retractablelanding gear-had a built-in potential for a gear-up landing. Italso had several new features that could be forgo tten and causetrouble, since they did not exist on the previously used Fordtri-engine monoplane and the single-engine mail biplanes.Too many gear-up landingsToday, it seems that one of the principal causes of accidentsin our Bonanzas and Barons is gear-up landings, which is proofthat a landing checklist was not used. Believe it or not, I actuallysaw three gear-ups in one day at POU, my home airport-{)neBonanza, one Cessna and one Staggerwing. Years ago I also witnesseda beautifully restored Bonanza land gear-up on Runway27 at OSH during the first-day rush.I witnessed two touchdowns with gear up, but go-aroundswere accomplished at the last moments. One was a militarybiplane that touched down with its tail wheel and the pilot realizedthe gear was up. He poured on the coal, but the nosewould not come up with full back control stick while the tailwheelwas on the runway until enough airspeed had beengained to lift the airplane off. There was no damage, but thepilot was grounded for a week.Another time, a Cessna "push-pull " passed a half dozen ofus who witnessed it. When the pilot felt the tips of the rear propellerclipping the runway, he opened to full power and wentaround for a proper landing. The rear propeller blade tips werebent over about an inch, the little bulges on the wheel well coverswere worn through from being dragged on the concrete,and the pilot was embarrassed.One Bonanza came to the shop at POU for a gear-up repair.It had had three previous gear-ups, and the repairs were so crudethey had to be redone.In my more than 80 years of flying I have seen many moregear-ups, but these are enough ro make you aware of the importanceof checklist use at landing time. Remember, there arethose who have done it and those who haven't yetiOther neglected checklistsIt isn't only the landing gear that is forgonen due ro fai lureto use a checklist, but other very serious mistakes occur. I haveknown several cases in which pilots took off wi th the fuel selectorvalve still on an almost empty tank, which had been left thatway after a previous flight, resulting in very serious accidentswhen the engine stopped soon after takeoff.There have been takeoffs made with the from cooling airinlets still plugged, so the engine overheated and failed. I havewitnessed them .Page 10960 www.bonanza.org ABS September 2008


IF elrer" pilot Iftelftber of ASS would diligentl" adhere to the Forlftallt"of checklists, we could IIkel" double our alread" good saFet" record.There have been cases when takeoffs were made with theengine cowling not fastened. Some very serious accidents haveoccurred with piston-engine airplanes taking off wi thout havingthe carburetors cleared of ice by using carburetor heat justbefore takeoff. That will sometimes occur after the engine hasbeen run up properly, but then a long wait occurs for a takeoffclearance while idling. Such incidents could have been avoidedby use of checklists.The checklist should contain a last look at the wings of theairplane before takeoff to detect ice or snow. There have beenmany serious accidents due to taking off with a very thin coatingof snow or ice on the wings and tai l. That is checked on theorigi nal walk-around inspection of the aiIplane, but can accumulateshonly afterward.It takes only a very, very thin coating of snow or ice todestroy the lift of the wings. In fact, I know of one case whena Boeing 247 failed to get off with such a thin coating of snowon the wings that the NC numbers could still be clearly readon the wings from the cockpit. In another instance, a DC-8crashed after takeoff at JFK when only an extremely thin coatingof ice collected on the wings, during a wait for takeoffclearance.Of course, that is what occurred in 1982 at WaShington,D.C., when the Air Florida 737 crashed into the bridge, with78 sad and unnecessary fatali ties. I saw one such accident rightat my home airpon when a twin-engine airliner, with only athin coating of snow, crashed to a total washout after takeoffwhen it could not lift out of ground effect.When I was flying my own helicopter under FAA Pan 135after my retirement from EAL, I was on a cross-country flightwhen the rotor blades took on ice and slowed down. [ had tomake three landings in hayfields to break the ice off of them,using a wood stick.When I taught my first grandson to fly from scratch in myBonanza at 16 years of age, I had him use the checklist foreverything: Before staning the engine to shutting it down,taxying. before takeoffs, before landings and after landings.I do not use touch-and-go landings wi thout a full stop, butafter clearing the runway and coming to a full stop the fl apswere raised, making cenain that the proper switch was used,and an after-landing check list used, every time.The checklists were the biggest pan of the instruction formy grandson. He learned landings beller that way, actuallyfaster than other students making touch-and-goes on the samefield at the same time. It gave him more time to think about hisprevious landing and his next one and corrections to be made.Touch-and-goes are absolutely improper in such an airplane,without using a checklist. He was given takeoffs afterrolling on touchdown, for emergencies, only shonly before solo.He learned faster and did a beller job of flying than the other students,and flew away in my Bonanza without me aboard whilethey watched with surprise and envy.In airline flying, the use of checklists is absolutelyrequired and checked by both pilots, one read ing the list andthe other checking each item. If every pilot member of ABSwould diligently adhere to the formality of checklists, wecou ld likely double our already good safety record.EDITOR'S NOTE: Johll Miller passed away ollhe age of 102 allJlllle 23, 2008.

Thoughtmembers would want to know.-John Ornellas, Avon, MassachusettsMore thanks & kudosIn the July Tech Tips (page 10859)a fellow from Kearney, ebraska, askedif any ABS techs had an engine blockheater they might recommend for his10-550. Neil Pobanz recommendedTanis, which he said was "the Cadillacof heaters. III just want to back up that recommendationfrom my own experience,having replaced my oil-pan-only heaterthat was already on my 10-520 when Ipurchased the aircraft.On a very clear but cold winter daylast year, I flew to Glenwood,Minnesota, where Tanis is located, andgot the red-carpet treatment from BobKrueger, president of Tanis, and hisentire crew. They pulled my V35B intothe hangar and gave me a tour of theplant and a personal demo of how theirheater system works.And now, having used it severaltimes since I purchased the heater, I cansay with confidence that the combinationof oil pan and cylinder-head heatersworks great. By the time those cylinderheads heat up, you could almost fry anegg on them (but not recommended!).Bob and his staff are very friendly,easy-to-work-with folks. You will betreated right and get an excellent heaterto boot.On the topic of being treated right,another fellow I would like to givekudos to is Joe Richardson and his crewat Air 51 in Lexington , Kentucky(KLEX). My wife and I flew there tocheck out the venues in Lexington forthe September ABS convention. Again,the red carpet was rolled out for us aswe taxied under the large canopy infront of their FBO.

I'm speaking of anongoing problem with pilots who do notknow there is a difference in cylindertemperatures taken at two differentlocations of the probe. When Mikespeaks about limiting the cylinder temperaturesto 400°F, it should be clearlydefined exactly where these temperaturesare measured.Most members are aware thatcylinder temperatures are measured andthe limits established on some enginesat the bottom spark plug. (E Bonanzaengines are one example.) Temperaturestaken at that location will run about40°F higher than a probe at the threadedboss lower on the cylinder ("the well").As I have written in several pastanicles, I limit the temperatures in myE-225 to 440°F, which would be Mike's400°F at the "wei!''' The actual listedlim it is 525°F at the bottom spark plug,a temperature reading that we all knowshould be avoided by any availablemeans.What I am saying is that 400°F is agood operational limit, but it sure getsall my E-people excited when they areshowing 425° to 450° if they are meas­IIring the temperatllres at the spark plllgalld are either not kllowledgeable or areforgetflll abollt the differellce ill temperaturesbetween the two locatiolls. Thereis no way to keep the #2 and #4 cylinderson an E engine below about 420° to450° during summer operations-again,measured at the bottom spark plug.In my July anicle (page 10874), Imentioned the split temperature readingbetween the two spots and the fact thatone must add 40°F to a "well" readingto get to the real temperature at thespark plug, the place where 525°F is theredline and that defines the temperatureof concern in those engines.- Lew Gage. ASS Currents columnistThanks to BPPPIn May I attended the BPPP clinicin Columbus, Ohio, and as usual, it wasoutstanding. Unfortunately, I became illprior to the flight review.

THE BARON & FUELCONSUMPTION ISSUESBY JACK SHANNON. BELLEVUE. WASHINGTONThe high cost of fuel and the image of the Baron as an inefficientairplane because it has two engines prompt me tosubmit the graph shown here.For comparision purposes. I selected a group of singleengineairplanes that one might own if one was considering theSSP. For consistency, I used performance data fromLandings.com. This reference provides fuel capacity, cruiseHow the 58P compares to selected single-engine airplanes70.0,--------------------,60.0~.; 50.0(!);;:040.0-L.LQ). ...i: 30 0-""oo~20 . 0 -10.0P210~ _ -. 5SP _ -B36TCA A PA-46-350P MalibuV35ATC & V35BTCA-~ Meridianspeed and range for a large number of airplanes. Range andcruise speed data allow a computation of uip time. That time,with a 3D-minute reserve, allows a computation of the rate of fuelconsumption.What is interesting about the graph is that the Baron appearsto have a higher rate of fuel consumption because it goes faster.In fact, it appears that fuel consumption is a function of cruisespeed rather than the number of engines.To verify this conclusion, I assumed that the four airplanesat the bottom of the graph define an average drag coefficient andaverage rate of fuel consumption for the required horsepower.Then I scaled that fuel consumption by cruise speed cubed.Cubed, because that average drag coefficient needs to be multipliedby velocity squared to get drag, and that drag (or enginethrust) must be multiplied by velocity again to get the proportionalincrease in horsepower, which has dictated the increase infuel flow. That's the dotted line in the graph, and it fits very well.Actually, the drag is a function of at least the weight, sizeand configuration; no two engines have the same specific fuelconsumption, particularly at partial power.

Itis these studs that are making the circular spots on the discs (yellow arrows) .When the brake linings become well worn (red arrows), theends of the studs come into contact with the discs. When thathappens, it leaves a tell-tale circular spot on the disc, These spatsindicate it's time to replace your metallic broke linings because ifleft unchecked, the stud would soon wear a groove in the disc,causing a very expensive repair.Interestingly, we found that this condition occurs primarily with metallicbroke linings (usually installed on wheel size 6.50 x 8). Spots do not appearon discs with organic broke linings (usually installed on wheel size 7,00 x 6)because the linings are attached to their backing plates with rivets, not studs.LTC (Ret) Adrian A.

Every year a surprising number of insurance claims arefiled on accidents that occur during taxiing. Learningto taxi an aircraft is one of the first operations astudent pilot is taught, but appare ntly it is one that is easilyforgotten. Maybe taxiing appears to be so elementary thatpilots become complacent.Operating an airplane on the ground during higherthan-normalor gusty wind conditions, or in close proxi mityto turbine-powered aircraft, can be hazardous for our smallgeneral-av iation aircraft. Many claims are filed each year thathave been caused by taxiing off the side of runways andtaxiways, striking run way markers, hangars or other aircraft,and running into potholes. This creates damage to wingtips,propellers and landing gear.The offending pilot is embarrassed to explain suchaccidents to the insurance company as well as the FAAinvestigator because there is seldom an acceptable reason fora taxi accident.The training rules all pilots study advise not to taxi anyfaster than a person can walk at a fast pace. The aircraftshould be taxied slowly enough that it will stop instantlywhen the brakes are applied, or that it will stop on its ownwhen the throttles are closed.Adhering to the fallowing taxi rules will help you avoidbeing a ground-operations accident statistic.• Stay alert while taxiing.• Taxi slowly and cautiously.• Check your brakes before moving more than the lengthof the aircraft.• Keep a sharp lookout outside the cockpit. This is not thetime to be reading maps, programming a GPS, using achecklist or copying ATC clearances.• If the clearance between objects looks too small , it probablyis. Stop the aircraft and shut down the engine, or getsomeone to wing-walk you through a congested area.• Avoid taxiing behind large aircraft, turbine aircraft or inhigh or gusty wind conditions.Propeller accidentsOther ground accidents that could be avoided involvepropellers. For instance, if at all pas ible, hand-proppingshould be avoided. Many people ignore safety precautionsand attempt to hand-prop the engine without having someonequalified at the controls of the aircraft. The person turning thepropeller should be properly trained in the hand-crankingtechnique. Do not ever consider hand-propping an aircraft byyourself!Another accident that happens too often involves deplaningpassengers who walk into spinning propellers. Many peopleare not accustomed to being around aircraft and maybecome disoriented or fail to see a moving propeller. This hashappened with both single- and twin-engine aircraft. Forsafety, engines should be shut down when picking up ordropping off passengers .Please remember, ABS members, that any of us can havea ground accident. So stay alert and stay cautious! @II IU .... en ...... IUIr 'I .. nlel eI ....... ,.. ..... US .r.ln. ".'11,.II'11II•• flle.1 '1.lr.leI .... e._ ' •• n .. •• a.n C.I,..
