Probable cause

The loss of engine power due to the failure of the engine exhaust valve in the no. 2 cylinder and the disregard of the Lycoming service bulletin by company maintenance personnel. Contributing to the accident was the high vegetation and trees located at the forced landing site.

Sequence of events

NTSB’s coding before 2008: each occurrence and phase of flight, and the causes and factors under it. The codes are defined in NTSB’s coding manual.

Analysis

The pilot executed an autorotation into high vegetation and trees following an engine failure. Post accident exam of the engine revealed the no. 2 cylinder exhaust valve failed. Examination of the engine logbook revealed Lycoming service bulletin 388A had not been accomplished.
