| Confidence Rating: |  Accident investigation report completed and information captured |
Witnesses reported seeing and hearing the airplane prior to its impact with the terrain. Several of these witnesses reported hearing the engine "sputtering" or "popping." A post crash fire engulfed the airplane, consuming all but the forward four feet of the fuselage. Control system integrity could not be conclusively determined; however, no evidence of a pre-impact failure was found. The engine was able to be rotated but damage from the post crash fire precluded determination as to the reason for the presumed loss of engine power. The terrain where the accident occurred was rising with vegetation about 8 to 12 inches tall. The ground scars and aircraft damage indicate that the bulkhead located just aft of the nose landing gear dug in during the forced landing resulting in the airplane nosing over.
Probable Cause: The loss of engine power for an undetermined reason. Contributing to the accident was the unsuitable terrain that was encountered by the pilot during the forced landing.
