A pilot experienced an engine failure in cruise flight while returning from a nearby airport where he had completed a biennial flight review. The aircraft landed in rough terrain and nosed over, with no mechanical issues found during post-accident testing.
What happened
The pilot departed his home airport to travel approximately 45 nautical miles to a different facility for the purpose of renewing an expired biennial flight review. After successfully completing the required flight check at that location, he began his return journey to his home base.
During the cruise portion of the flight back, the engine ceased operation. The pilot was forced to execute a landing in rough terrain. Upon impact, the aircraft nosed over.
The investigation
Following the accident, mechanics performed an engine test run to determine the cause of the in-flight failure. The inspection did not disclose any mechanical failures or malfunctions within the powerplant that would explain the loss of power.
Probable cause
The engine failed during cruise flight for reasons that could not be determined, as post-accident testing revealed no mechanical issues.
