Probable cause
A partial loss of engine power due to the No. 3 cylinder’s stuck exhaust valve.
NTSB analysis
The student pilot and flight instructor reported that the engine lost partial power during cruise flight. The instructor assumed control of the airplane, attempted to restore power, and performed a forced landing to a cleared area of wooded terrain, resulting in substantial damage to the airplane. The postaccident examination of the engine revealed that the exhaust valve in the No. 3 cylinder was stuck in the open position. Based on this finding, it is likely that the partial loss of engine power was the result of the No. 3 cylinder’s stuck exhaust valve. The engine maintenance records were not available for review, and the maintenance history of the engine could not be determined.
