AD 2005-19-11

October 3, 2005

AD 2005-19-11, Lycoming Engines AEIO-360, IO-360, O-360, LIO-360, AEIO-540, IO-540, O-540 and TIO-540 Series Reciprocating Engines. 

Summary:  The FAA is adopting a new AD for certain Lycoming Engines (formerly Textron Lycoming) AEIO-360, IO-360, O-360, LIO-360, AEIO-540, IO-540, O-540 and TIO-540 series reciprocating engines rated at 300 horsepower or lower.  This AD requires replacing certain crankshafts.  This AD results from reports of 12 crankshaft failures in Lycoming 350 and 540 series engines rated at 300 HP or lower.  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. 

DATES:  This AD becomes effective October 21, 2005.
