Aircraft Accident/Incident Report

Healdsburg, California 95448
Thursday, August 30, 2012 12:00 PDT

NTSB Narrative Summary Released at Completion of Accident

The pilot reported that during cruise flight, the engine lost power, and he performed the emergency procedures; however, the engine would not restart. The pilot then performed a forced landing to an open field. During the landing roll, the nose gear collapsed. Postaccident examination of the engine revealed that the fuel pump would not pump fuel when the driveshaft was actuated. Further, during testing, the fuel pump did not produce adequate pressure without the test bench priming pump in operation. The fuel pump was removed and disassembled, and unidentified pliable debris was found in the vapor return jet. The debris was removed from the vapor return jet, and the fuel pump was reassembled. Following reinstallation on the test bench, the fuel pump was found to operate and produced pressure in excess of the manufacturer specifications. It is likely that the debris restricted the fuel flow and the engine subsequently lost power. Due to the compromise of the fuel system during the accident, the source of the debris could not be determined.

NTSB Probable Cause Narrative

The loss of engine power during cruise flight due to the failure of the engine-driven fuel pump as a result of unidentified debris within the vapor return jet.
