NTSB Narrative Summary Released at Completion of Accident

The 2,292-hour flight instructor reported that after takeoff, the engine lost power. After initiating a forced landing to a field, the left wing impacted a tree during landing roll and the airplane came to rest upright. Review of the engine logbooks revealed that the starter clutch assembly was replaced twice within 15.64 hours. Examination of the engine revealed that the starter-clutch assembly would not rotate freely, and the starter-clutch shaft was severed into two pieces. The bolts that attach the accessory drive-gear to the camshaft were also severed.

NTSB Probable Cause Narrative

The loss of engine power due to the separation of the accessory drive gear bolts, and the failure of the starter-clutch assembly. A contributing factor was the lack of suitable terrain for the forced landing.
