Analysis

During an emergency off airport landing, subsequent to a power failure, the aircraft experienced a nose over and suffered substantial damage. The pilot reported no injuries. Investigation after the accident revealed a valve sticking problem in the engine. During the post acc exam the eng would run at high setting but quit when reduced to cruise pwr. The valve stem clearances were found to meet specs however there were excessive carbon deposits at the base of the stems on the intake valves. The engine had been overhauled 350 hours previously and had a 100 hour inspection 49 hours previously.
