paint. Apply with a cloth or a soft brush
soaked in the mixture.
(3) Wipe off excess mixture. When ap
plying the mixture take care that as little as
possible is deposited on exhaust pipes or col
lector rings to avoid a fire hazard when the en
gine is started. Keep the ignition wires, pro
peller anti-icer feed hose, tires, and other rub
ber parts free of the mixture.
d. Most parts of landing gear wheels are
made from magnesium or aluminum alloys
which corrode rapidly unless carefully pro
tected. When the aircraft operates near salt
water and off coral beaches, the corrosion can
be very rapid. Inspect wheels to determine the
paint condition.
e. Refinish portions of a wheel where
paint has deteriorated, peeled, or chipped.
b. Where maximum corrosion protection
is desired on stationary parts, use exterior sur
face corrosion preventive compound, Specifi
cation MIL-C-16173, grade I.
c. Wipe the exposed portion of the land
ing gear shock strut piston with a cloth soaked
in the applicable hydraulic fluid.
f. Except for friction and bearing sur
faces, apply a protective coating to all parts of
wheels and brake assemblies.
