NTSB narrative
While the commercial pilot was maneuvering the airplane during a local flight, the engine lost total power. The pilot was unable to restart the engine, and he made a forced landing to a nearby road. After landing, the pilot saw a car on the road and attempted to turn the airplane to the right; however, the airplane's right wing impacted a road sign and a barbed wire fence.
Postaccident testing revealed that the engine-driven fuel pump was not functional; thus, the fuel contained in the main tanks could not be transferred to the header tank. Therefore, the loss of engine power was likely the result of fuel starvation after the available fuel in the header tank had been depleted. Although the airplane was equipped with a header tank fuel gauge, the pilot failed to identify that the fuel level in the header tank was decreasing prematurely.
Probable cause
The failure of the engine-driven fuel pump and the pilot's failure to identify the pump's failure, which resulted in a loss of engine power due to fuel starvation and a forced landing on a road, during which the airplane hit obstacles.

- 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. 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.
