Aircraft Accident/Incident Report

Lompoc, California 93436
Thursday, September 30, 1993 16:48 PDT

NTSB Narrative Summary Released at Completion of Accident

According to the pilot, during initial climb on the maintenance test flight the airplane gained between 250 and 300 feet altitude when the engine backfired two times and quit. The pilot stated that he turned the airplane to avoid colliding with obstacles and crashed into a plowed wet field. Exam of the airframe and engine did not reveal any mechanical failures. Fuel was found in both fuel tanks and the fuel pumps were found functional. No fuel was found in the carburetor. Prior to the accident flight, the pilot, who was also an A & P mechanic, had performed maintenance on the airplane. The last annual inspection had been completed over seven years earlier, and the airplane had not been flown since that time.

NTSB Probable Cause Narrative

was fuel starvation. A factor in the accident was the mechanic's inadequate inspection of the airplane.
