## Probable cause

The partial loss of engine power due to the exhaust valve rocker retaining stud backing out of the cylinder head, which resulted in the exhaust valve being stuck in the closed position. Contributing to the accident was the pilot’s failure to configure the airplane and fly it in a manner that would allow him to make  the emergency landing in the field rather than overfly it, and the pilot’s failure to have the engine overhauled according to the recommended overhaul interval.
