NTSB narrative
The airplane was in cruise flight about 2,500 feet, when the engine experienced a total loss of power. The pilot attempted to troubleshoot during the descent, but could not restore engine power. In close proximity to the ground, the pilot determined that the airplane would not clear the power lines in its path, turned away from the power lines, and noted that the airspeed was "under a hundred" as he initiated the turn. The pilot could not recall the remainder of the flight, and stated that his next recollection was waking up in the wreckage. After the accident, the engine was placed in a test cell and started, but it would not sustain operation without application of auxiliary fuel pressure. The engine was stopped, and examination revealed that the engine-driven fuel pump gasket was leaking, and the pump displayed considerable fuel staining on its exterior. Tightening of the pump produced the same results. The engine-driven fuel pump was removed, and replaced by a slave pump. The engine then started immediately, accelerated smoothly, and ran continuously without interruption with no application of auxiliary fuel pressure.
Probable cause
A total loss of engine power due to a leaking fuel pump gasket.

- Unreviewed is an editorial label, not an investigation status. API-sourced is not report-checked or human-reviewed. Explicit event totals are used without summing aircraft injury tables; onboard allocation is withheld. Unknown values remain unknown. The operation category is mapped from the NTSB-reported FAR part and has not been reviewed.
- Filled from the NTSB case API where the bulk record had no value: investigation status, coordinates. Values present in the bulk record are kept.
- The date is the local date, which is the same as the UTC date the NTSB stores.
