- Flight rulesThe regulations the flight operated under: in the US, Part 91 (general aviation), Part 121 (airlines), Part 135 (air taxi and commuter) and others; for flights abroad, the NTSB's coarser commercial or non-commercial code. Glossary
- Part 91: General Aviation
- Phase of flightThe stage of the flight when things started to go wrong: standing, taxi, takeoff, initial climb, en route, maneuvering, approach or landing. Glossary
- Maneuvering
- Defining eventThe single coded event the NTSB judges best describes what happened (records from 2008 on). Older records name the first occurrence in the sequence instead. Glossary
- Loss of engine power (partial)
- DamageDestroyed: beyond practical repair. Substantial: damage that affects the structure, performance or handling and normally needs major repair. Minor: less than that. Glossary

NTSB narrative
The pilot reported that the airplane was over mountains and near the destination airport when the engine temperature and fuel flow gauges “dropped” and the engine lost partial power. The pilot pushed the throttle in and turned on the auxiliary fuel pump to the “high” position, but those actions had no effect on the engine power. The pilot troubleshot the loss of power; however, there was no change. The pilot then located a flat, treeless area for a forced landing. During the forced landing the landing gear separated and the airplane came to a stop upright. The airplane sustained substantial damage to the forward fuselage, firewall, and left outboard wing. A postaccident examination of the airplane’s engine-driven fuel pump showed that one of the pump’s two carbon vanes had fractured in half. How the carbon vane fractured was not determined. The severed fuel pump vane likely resulted in fuel cavitation, a drop in pump outlet pressure, a gradual decrease in engine rpm, and subsequent partial loss of engine power.
Probable cause
The partial loss of engine power due to a vane failure in the engine-driven fuel pump.

Source notes (4)
- 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, cause areas. 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.
