Aircraft Accident/Incident Report

Elma, Washington 98541
Wednesday, February 27, 2002 15:30 PST

NTSB Narrative Summary Released at Completion of Accident

The pilot reported that while turning from downwind to base leg, the engine surged, coughed, then quit. The pilot tried unsuccessfully to restart the engine. Unable to reach the runway, the pilot initiated a forced landing to an open field. During the landing roll on the soft terrain, the aircraft nosed over. During the post-accident inspection of the engine, no evidence was found to indicate a mechanical failure or malfunction. Local weather conditions indicated carburetor icing conditions favorable for serious icing at cruise or climb power. The pilot reported that he had been using carburetor heat.

NTSB Probable Cause Narrative

Loss of engine power for undetermined reasons. Soft terrain was a factor.
