| Confidence Rating: |  Accident investigation report completed and information captured |
The pilot reported that while cruising at 11,500 feet MSL over 10,000 foot terrain, he 'noticed the oil pressure gauge was reading 0.' Approximately 5 minutes later, the engine 'clanked and started to break apart internally.' Subsequently, a 'few minutes' after that, the engine seized. The pilot executed a forced landing between trees on a rocky ridge top. During the landing roll, the airplane hit a rock, nosed over and came to rest in an inverted position. Postcrash examination of the engine revealed extensive internal damage. Subsequently, the parts were sent to a metallurgical laboratory for analysis. It was determined that the number one piston had developed in-service fatigue cracks and subsequently disintegrated; which in turn caused the general failure of the engine.
Probable Cause: The loss of engine power due to the fatigue failure of the number one piston. A factor was the lack of suitable terrain for the forced landing.
