Confidence Rating: Accident investigation report completed and information captured
The pilot was conducting a local flight when the engine started to surge and run rough. He attempted to troubleshoot the problem, but was not able to restore engine power and located a precautionary landing site at an abandoned airstrip. During the landing roll, the airplane drifted right, and the right wing impacted vegetation, which resulted in a ground loop and substantial damage to the airplane.
A postaccident examination of the engine, airframe, and propeller revealed no anomalies that would have precluded normal operation, and the reason for the partial loss of engine power could not be determined.

Probable Cause: The pilot's failure to maintain directional control during a precautionary landing, which resulted in a ground loop. Contributing to the accident was a partial loss of engine power for reasons that could not be determined.
