Gust locks Lee Elson Tujunga, California Q: Raytheon has released SB 27-3459 regarding gust locks. They say this is a MandalOry Bulletin and that they've requested an AD. As near as [ can tell , they want me to buy one of their gust locks. I currently have an Avibank Ball-Lok (MS 17985-550) with a yellow warning flag that works just fine. Assuming that the AD (when issued) will just refer to this SB, what are my options Any idea how much the Beech gust lock costs A: For Pan 91 operations, a Mandatory Service Bulletin is only mandatory if it becomes an Airworthiness Directive. We successfully fought the AD on this and it came out as an SAIB instead, which is advisory only. The Beech gust lock is expensive as it had 10 be designed to prevent takeoff due to owners making the ultimate mistake. We felt this was a training issue, not maintenance. Beech, of course, needed something for protection, so they issued the Service Bulletin. We feel any effect ive gust lock with warning flags should be ok. This does not include a ground-down tractor bolt. Local instructors Rondal Wojciehoski Stevens Point. Wisconsin Q: Who do you recommend as a Bonanza instructor in Wisconsin [ have three panners in this plane and we would like training. A: ABS Director Craig Bailey (847-646- 8866) is in nonhem lIIinois and would also know other BPPP instructors in the area. Tip tanks Greg Porker Cedar Rapids. Iowa Q: I am looking for paperwork for the original 12-ga\. flight extender tip tanks. I have the Fornl 337, but Beryl D'Shannon says it can't provide paperwork. A: As you have a 337 for the original installation, it should be evident that you aren't bootlegging an installation but need data for continuing maintenance. Therefore it's legal for anyone who has what you need 10 provide copies to you. D'Shannon will provide, for a mininlum fee, copies of the early versions if they have it and if you have proof of original installation. This is a reasonable requirement. Members: Can anyone help us out Tip tank problems Ray Phelan Portland, Oregon Q: I have Flight Extender RB4-1 00 tip tanks, STC SA28EA. I am looking for the schematic for the tank system, and Beryl D'Shannon does not have it. Any suggestions The question we are trying to resolve is that the line feeding from the RH tank has a check valve installed and two lines branching out to the fuel selector. The LH tank goes straight into the selector. Why Is this correct The aircraft at one time had ferry tanks in it, and [ wonder if this is left over from that. Can the tip tanks just feed straight from the tank to the fuel selector or should one or both tanks have this check valve A: I suspect that was from the ferry tanks. It probably was not a factory installation, so there wo uldn't be anything there. The problem is that the systems evolved and one generation is a lot different than later ones, although still legal, except there's no data available. Sometimes someone knows one variation and thinks they were all that way and that any other types are wrong. We have to be detectives and son out how yours became what it is. Kind of hard if records are lost or incomplete. Members: Any feedback to help us out here Wing bolt fittings Bil/Hoglan Georgetown. Texas Q: I have a 1955 F35 and am having trouble locating the part number for the clips that rivet to the bathtub fitling wing bolt covers. I have looked in the parts book, old magazines and ABS CD-ROM. Can you help A: The wing bolt cover ctip pan numbers are 35-105005-4 and 35-105005-6. Broken aileron trim Loren Bouman Lewisville, North Carolina Q: I own a 1975 V35B with center control yoke on which the spring in the central aileron ABS Fe b ruary 2003
control knob is broken. I understand the knob can be disassembled (left-hand threads) but I can't fmd an order number for the spring. Could you provide that pan number If it is not available, how can this be repaired A: The unit was originally built by Aircraftsmen in Oklahoma City, but they are no longer in business. I have heard that Woodland Aviation (530- 662-9631) could find parts or try Crossroads Aviation (972-239-0263). If you are doing it yourself, there is an excellent anicle on the aileron trim disassembly in the May 1991 ABS Magazine, page 2785. Trim tabs Tom Henderson Ventura, California Q: We have a 1966 35-C33A. At annual, our IA replaced the bushings at the elevator trim tab horns (PIN 105740X-ZHOIl5). He also replaced the retaining hardware with self-locking nuts (i.e. nyloc), which he tightened up very securely. The old hardware was the original (AN bolts, nuts and cotter pins). [ know ABS recommends that those bolts be loose enough to spin with your fingers on V-tail aircraft. Should they be similarly loose on our Debonair A: The pans book calls for castellated nuts and cotter keys. On the 35 models, they should be loose enough that they don't flex the cable in the swaged fitting end. On the 33, with the fork tightened on the bushing, they should be where the bolt is tight to the fork but does its fl ex between the bolt shank and the bushing. Broken trim switch John Lyman Mounf Kisco, New York Q: I have a 1979 B55, TC-2210, with a KFC-200 AP/FD. I managed to break the trim switch on the yoke. Do you know any source for these switches other than King (which wants $850) A: Try Elliott's Avionics (309-799- 3183), lenkins Air Service (775-33 1- 4905) and Crossroads (972-239-0263). Elevator corrosion Dory/Aaron Houston. Texas Q: [have a 1965 B55 in annual. The mechanic says there is corrosion that must be repaired on the elevators. He says the repair options are: Repair it, reskin it or replace them with aluminum elevators. [ know you have not seen the amount of corrosion on the control surface, but what would be your recommendation to handle this problem properly Who is the contact to get the aluminum replacement parts A: Talk to Glen Biggs in your area (405-947-3361). Others are Crossroads Aviation (972-239-0263), Stebbins (800- 852-8155) and Princeton (763-389-2 134). Minor corrosion that can be mechanically removed by Scotchbrite (not over .(02) can then be treated and repainted. More than that should be reskinned. Many times corrosion returns because the rinse after the treatment with Magnadyne isn't dried enough and moisture is trapped between the skin and the primer. Zinc chromate isn't good, as zinc and magnesium react. Likewise, methylchloride strippers must really be neutralized, as it reacts. Oxygen tank, panel blanks George Cotalano Scottsdale. Arizona Q: [ have a 1968 V35A-TC with factory oxygen. The tank is located directly in front of the front seats. I had heard that a Kevlar tank was STC'd for a rear bulkhead installation. Is this true and do you know if the mounting is anything special or panicularly difficult I'm trying to get the leg room and approach plate book area back in the from seat area when I do a new interior. Also, does anyone sell uncut panel blanks for this model V-util A: Check with Nelson Oxygen (800- 547-2558) and Air Mod Interiors (5 13- 732-6688). For dashboard panels, try Arrell (805-604-0439). Hail damage Paul Prior Pismo Beach. California Q: I have a 1972 V35B that was hailed on while tied down at CYS, Cheyenne, Wyoming. I think it is going to require reskinning from the forward spar aft on the wings, ailerons and flaps. The tail feathers are also going to require some reskinning. The consensus is that the damage is cosmetic and has not affected airwonhiness. I would appreciate any guidance you can offer, as well as suggestions of shops that can handle such repairs, preferably in the central California area. A: We agree that, unless the skin is torn , it can be flown. Try Barber Aviation in Madera (209-675-0183), Woodland (530-662-963 1), or Cheyenne Airrnotive (307-778-2000). Spare POH Haywood Schmidt Winchester, Massachusetts Q: Where is the best place to get a POH to keep at the house for reference A: Beech's tech material distribution center (TMDC) (800-796-2665) is the best source. Another is Essco (330-644- 7724). Give your serial number. Of course, any supplements you have added will not be there. Manuals PaulOdum Oklahoma City. Oklahoma Q: Where can I get a pans and maintenance manual for a 1960 M Bonanza Also, I am planning to do the 10-520BB mod. Can [ get the parts and maintenance manuals in hard copy and CD A: Hard copy is available from Beech TMDC (800-796-2665). A CD is available from the ABS Company Store ABS February 2003 Page 7665
