| Confidence Rating: |  Accident investigation report completed and information captured |
The pilot reported that about 5 miles from the destination the engine started to run rough, and about 20 seconds later the engine lost power. His attempts to restore engine power were unsuccessful. The pilot subsequently performed a forced landing to a field. During the landing roll the airplane nosed over on the soft field. A postaccident examination revealed that the No.3 cylinder exhaust valve push rod had buckled and fractured near mid-length. The push rod fracture surfaces showed failure signatures consistent with overload precipitated by a stuck valve. No other engine anomalies were observed.
Probable Cause: A loss of engine power due to a fractured push rod precipitated by a stuck exhaust valve.
