NTSB narrative
According to the pilot, he was in cruise flight at 12,500 feet mean sea level when the engine stopped running. Attempts to restart the engine were unsuccessful. The pilot performed a forced landing to rolling, uneven terrain resulting in substantial damage. Examination of the engine revealed the fuel pump drive gear was pressed into the flange and would not rotate by hand. Several of the gear teeth exhibited damage. The gear shaft exhibited rotational scoring. Half of the engine side lip of the flange was missing. The flange housing was discolored, consistent with heat due to oil starvation. Examination of the engine, fuel pump, remaining engine components, and fuel system revealed no anomalies.
Probable cause
The failure of the engine driven fuel pump flange due to oil starvation, resulting in the loss of engine power due to fuel starvation. Contributing to the accident was the lack of suitable terrain for a forced landing.

- 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.
