Read the full NTSB narrative
According to the pilot, while conducting a local flight, he heard a "pop" followed by a partial loss of engine power. The airframe started shaking badly, he pulled power to idle, established best glide, and contacted Air Traffic Control (ATC). ATC provided alternate airports and current weather information. Unable to maintain altitude, he initiated a forced landing to a clearing on the beach. During the landing roll, the airplane impacted a rock retaining wall, which resulted in substantial damage to the fuselage and left horizontal stabilizer. Examination of the engine revealed that the No. 4 exhaust valve was fractured. Metallurgical examination of the fracture surfaces on the exhaust valve revealed that it had fractured due to fatigue. The fatigue fracture of the No. 4 exhaust valve likely led to the partial loss of engine power.
