Probable cause
The partial loss of engine power due to a stuck exhaust valve.
NTSB analysis
The noncertificated pilot and two passengers were departing the airport for a local flight. On departure, the pilot noted that the airplane's engine did not produce full power and that the airplane would not climb as expected. The airplane collided with a sign and a vehicle before coming to rest on a golf course. Examination of the engine found that the No. 1 cylinder exhaust valve was stuck in the open position; no other anomalies were detected with the airframe and engine. It is likely that the reduced engine power was a result of the stuck exhaust valve, which would have severely limited the airplane's climb performance.
