(2) Procedure
(a) In the event of a foreign object strike, an inspection is
required before further flight. If the inspection reveals
one or more of the following indications, the propeller
must be removed from the aircraft, disassembled and
overhauled in accordance with the applicable propeller
and blade maintenance manuals.
1 A loose blade in the hub.
2 Any noticeable or suspected damage to the pitch
change mechanism.
3 A bent blade (out of track or angle).
4 Any blade diameter reduction.
5 A bent, cracked, or failed engine shaft.
6 Vibration during operation that was not present
before the event.
(b) Nicks, gouges, and scratches on blade surfaces
or the leading and trailing edges must be removed
before flight. Refer to the Blade Repairs section in the
Maintenance Practices chapter of this manual.
(c) For engine mounted accessories - for example,
governors, pumps, and propeller control units
manufactured by Hartzell Propeller Inc. - if the
foreign object strike resulted in a sudden stop of the
engine, the unit must be disassembled and inspected
in accordance with the applicable maintenance
manual.
(d) Regardless of the degree of damage, make a log book
entry to document the foreign object strike incident
and any corrective action(s) taken.
