C. SERVICING
The following practices will add to the service life of your wood propeller.
(a) Inspect and check propeller attaching bolt torque at least every 50 hours
according to the Bolt Torque Check Procedure. More frequent inspections may
be necessary when climate changes are extreme, such as a change of seasons.
(b) When the propeller is not in use, place the propeller in a horizontal position and if
it is exposed to the weather, cover it with a waterproof cover.
(c) Do not use the propeller as a tow-bar to move your aircraft.
(d) Protect your propeller from moisture and UV exposure by waxing with an
automotive type paste wax at least once a year. Keep the tip drain holes in metal
tipping clear.
(e) Avoid running the engine up in areas containing loose stones and gravel.
(f) Finish loss off the leading edge is a normal wear item, and is dependent on the
amount of operation in rain and grit.
(g) Touch up worn finish areas and scratches with spar varnish. Return the propeller
to the factory or approved repair station for total worn areas larger than 4x4" or
scratches deeper than 1/32".
(h) Inspect frequently for bruises, scars, or other damage to wood and blade leading
edge protection.
(i) Damage to the wood or leading edge that is 1/16" deep or less without breaking
the finish is acceptable.
(1) REMOVAL
(a) Mark the aft bulkhead propeller and spinner with tape, so they are reinstalled in
the same orientation.
(b) Remove the spinner.
(c) Remove the safety wire on the propeller mounting bolts.
(d) Remove the propeller bolts.
