AD NUMBER: 2004-10-14
MANUFACTURER: Textron Lycoming (CORRECTION)
SUBJECT: Airworthiness Directive 2004-10-14
SUMMARY: The FAA is adopting a new airworthiness
directive (AD) that supersedes an existing AD, for Lycoming Engines
(formerly Textron Lycoming), direct-drive reciprocating engines
(except O-145, O-320H, O-360E, LO-360E, LTO -360E, O-435, and
TIO-541 series engines). That AD currently requires inspection of
the crankshaft gear installation and rework or replacement of the
gears where necessary after a propeller strike, sudden stop page,
at overhaul, or whenever gear train repair is required. This AD
requires the same actions but makes the correction that the
existing gear retaining bolt and lock plate be removed from service
and new hardware installed, and revises the definitions for sudden
stoppage and propeller strike. This AD results from a change to the
definition of a propeller strike or sudden stoppage. We are issuing
this AD to prevent loosening or failure of the crankshaft gear
retaining bolt, which may cause sudden engine failure.The FAA is
