B. MAINTENANCE PRACTICES
(1) REMOVAL
(a) Remove the spinner.
(b) Cut and remove the safety wire from the propeller bolts.
(c) Remove the propeller bolts. Assistance may be needed to hold the propeller and
aft spinner bulkhead.
(2) INSPECTION
(a) Examine the propeller blades for corrosion, cracks, nicks, or dents beyond the
permissible limits. (These limits will be found in the propeller manufacturer's
service manuals). If the propeller is unserviceable, replace it with a new one and
return the damaged propeller to the factory.
(b) Inspect the attaching bolts for worn or damaged threads and heads. Replace
damaged bolts with new ones.
(c) Inspect the spinner bulkheads for cracks or broken brackets. Replace on
condition.

rear/mounting face of the propeller, and the pilot bore. Carefully examine each
surface and especially examine the end of the crankshaft pilot stub. Even minor
nicks or burrs must be smoothed.
(b) MAKE SURE the propeller attaching bolts, and the threads in the drive bushings
or retaining nuts are clean and dry.
(c) Be certain that the magneto switches are off, and that both magnetos are
grounded.
(d) Place the aft spinner bulkhead on the crankshaft flange, oriented so that the
propeller will be centered over the 2 crankshaft flange bushings that are flush.
Tape in place.
(e) Position the front spinner bulkhead over the front of the propeller and insert the
bolts with washers.
(f) Position the propeller so that it is centered over the two crankshaft flange
bushings that are flush and tighten the bolts snug.
