Aircraft Accident/Incident Report

Merced, California 95340

NTSB Narrative Summary Released at Completion of Accident

The pilot stated that he had departed the Merced airport approximately 1400. He climbed upwind until reaching an indicated altitude of 700 feet, and then began a left turn to 210 degrees for an on-course heading to Frazier Lake. At this point, he began to feel a slight loss of engine power, followed by a slow reduction of engine power, which eventually reached a nearly wind milling condition. He pumped the throttle, but the engine did not respond. He attempted to return to the airport, but realized he was too far away to land on the runway. He landed in a plowed field, where the airplane nosed over. According to the pilot, the wing tanks were empty at the time of departure, and the only tank in use was the fuselage tank. He stated that a possible cause of the engine failure was the use of a nonvented fuel tank cap. A post accident examination of the engine revealed the only discrepancy was a nonvented fuel cap on the fuselage tank. As fuel was being drained from the tank through the carburetor the drain flow ceased. The fuselage fuel tank cap was removed, a vacuum sound was heard, and the drain flow began again. The pilot stated he had switched the fuselage fuel tank cap prior to the last annual inspection that occurred 6 months and 8 hours prior to this flight.

NTSB Probable Cause Narrative

The pilot's improper modification of the airplane when he switched a nonvented fuel cap to the fuselage tank. A factor was the inadequate annual inspection.
