DE-ICE AND ENGINE SYSTEM CHECKS TO
PERFORM AFTER A PROPELLER LIGHTNING
STRIKE.
(1) General
(a) In the event of a propeller lightning strike, an inspection
is required before further flight. It may be permissible
for a propeller to be operated for an additional ten (10)
hours if the propeller is not severely damaged and
meets the requirements in paragraph 5.B.(2).

the propeller must be removed from the aircraft,
disassembled, evaluated, and/or repaired by a
certified propeller repair station with the
appropriate rating.
(2) Procedure for Temporary Operation
If temporary additional operation is desired before propeller
removal and disassembly:
(a) Remove spinner dome and perform visual inspection
of propeller, spinner, and de-ice system for evidence
of significant damage that would require repair before
fl

propeller hub).

LIMITS FOR ANY ADDITIONAL FLIGHT.
(b) If the only evident damage is slight arcing burns to the
blades, then operation for ten (10) hours is acceptable
before disassembly and inspection.
(c) Perform a functional check of the propeller de-ice
system (if installed) in accordance with aircraft
maintenance manual procedures.
