Probable cause

The NTSB’s determination of the probable cause, and any contributing factors.

The total loss of engine power for undetermined reasons. A contributing factor was the lack of suitable terrain on which to make the forced landing.

Analysis

The pilot stated that while at cruise flight at 3,700 feet MSL, he made a power reduction in preparation to descend to 3,000 feet. At that time he heard a loud bang and the engine quit suddenly and completely. No problems were found with the fuel or the airplane's fuel or electrical systems. The engine operated normally on a test stand, and was disassembled and later returned to service with no problems noted.
