Overhaul schedule
Gebhard Munz, Schorndorf, Germany
I have some questions about the overhaul schedule from the Bonanza
Q: shop manual. My V35B plane has been in Germany since new, and always
privately owned. It has complete logs, with total time 2208 hours, 1954 logged
landings, and no damage history. Can you give me your advice about the
following components regarding the TBO?
x Landing gear actuator – shop manual states 2000 hr
x Trim tab actuator – 2000 hr
x Flap flexible shaft, gearbox, motor and drives, actuator – all 2000 hr
A:
In the USA when operating under Part 91 (private flying only), we do not
have to adhere to the recommendations in the maintenance manual.
The following items are suggested due to history on many aircraft:
Every 500 hours –
x Complete 500 hour magneto inspection.
x Overhaul alternator (IO-520 and IO-550 gear-driven units).
x Replace main system air pump if using a dry pump.
x Replace paper air inlet filter elements per AD 84-26-02.
Every 2000 hours –
x Replace nose gear retract rod bearings (3 each), tension spring, aft
rod attach bolt and shear pin.
x Replace or overhaul landing gear motor.
x Overhaul landing gear actuator if leaking, or if at any time it is hitting
the internal stops.
Every 20 years –
x Replace wing bolts.
German regulations may differ on whether maintenance manual recommendations
are mandatory —BR
Q:
A:
Hurricane damage
Raymond Gill, Milford, Connecticut
The airport was underwater after Hurricane Sandy, and the water level
was about at my 1947 Bonanza’s wheel hub. Is it required to change the
bearing and races, or can they been cleaned and repacked?
If the wheel was partially submerged, I recommend removing the wheel
completely and breaking it down as if you were changing the tire.
By doing this you can inspect the inside of the wheel halves, tire bead,
bolts, bearings, and races. If all looks normal, clean and dry the assembly
and then reassemble normally. As long as no rust has formed on the bearings
or races, you can clean, dry, and service them with fresh grease. If there is
any doubt in their airworthiness, replace them. —CB
