MANUFACTURER: Textron Lycoming
SUBJECT: Airworthiness Directive 2006-06-16 SUMMARY: The FAA is
adopting a new airworthiness directive (AD) for certain Lycoming
Engines (formerlyTextron Lycoming) AEIO-360, IO-360, O-360,
LIO-360, and LO-360 series reciprocating engines.
This AD requires replacing certain crankshafts. This AD results
from a crankshaft failure in a Lycoming LO-360-A1H6 reciprocating
We are issuing this AD to prevent failure of the crankshaft,
which could result in total engine power loss, in-flight engine
failure, and possible loss of the aircraft.
