Incident Overview
A pilot reported that while the aircraft was cruising at 10,500 feet mean sea level (MSL), the engine lost power and could not be restarted. During the subsequent emergency landing, the nose gear struck a rock and collapsed.
Post-Landing Examination
After the landing, the aircraft was inspected. Initial attempts to start the engine were unsuccessful, and evidence of a fuel blockage was noted. The engine-driven fuel pump was removed and bench-tested, where it was found to operate normally. The pump was reinstalled, and thereafter the engine started and ran normally.
Conclusion
The cause of the temporary fuel blockage could not be determined. No further issues were reported with the engine after the fuel pump was reinstalled.
