NTSB narrative
The private pilot reported that while in cruise flight, during a Title 14, CFR Part 91 cross-country personal flight, all engine power was lost. While performing emergency engine procedures, he activated the electric auxiliary fuel pump, and noted that the engine fuel pressure was reading zero. Unable to restore engine power, he selected an open area that was surrounded by trees as an emergency landing area. The airplane landed short of the intended landing site, struck a large stand of trees, and nosed over. The airplane sustained substantial damage to the wings, fuselage, and empennage. A postaccident inspection of the airplane's fuel system components revealed that the electric auxiliary fuel pump was inoperative, and the vapor injector orifice in the engine driven fuel pump was blocked by a 1/8-inch long metal shaving.
Probable cause
A partially blocked fuel pump, which resulted in a loss of engine power while in cruise flight. A factor associated with the accident was an inoperative electric auxiliary fuel pump.

- 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: local date, investigation status, coordinates. Values present in the bulk record are kept.
- The date is the local date; the NTSB stores the UTC date 2005-06-06.
