- 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
- Initial climb
- First occurrenceThe 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
- Partial loss of engine power (mechanical failure)
- Also codedOther events the NTSB coded in the sequence, such as a wire strike after a loss of power. Flight Findings uses them for its kinds of event. Glossary
- Fuel starvation
- 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 DEPARTED ON A LOCAL FLIGHT WITH THREE PASSENGERS. THE ENGINE START, TAXI, AND INITIAL TAKEOFF WERE NORMAL. AS THE AIRPLANE FLEW OVER THE END OF THE RUNWAY AT 50 TO 75 FEET, THE ENGINE LOST POWER. THE PILOT INITIATED A TURN BACK TO THE AIRPORT, DUE TO TREES DIRECTLY AHEAD. AT THE COMPLETION OF THE TURN, THE RIGHT WING STRUCK THE GROUND. AN EXAMINATION REVEALED THE ENGINE FUEL PUMP, MANUFACTURED PRIOR TO 1978, HAD FAILED DUE TO A WORN ROD SLOT AND LINK ARM. THE AIRPLANE WAS EQUIPPED WITH AN ELECTRIC BOOST PUMP; HOWEVER, THE AIRPLANE MANUAL DID NOT DIRECT OR DISCUSS THE USE OF THE BOOST PUMP, AND THE BOOST PUMP HAD NOT BEEN TURNED ON FOR THIS FLIGHT.
Probable cause
Failure of the engine fuel pump, which resulted in fuel starvation and loss of engine power over an unsuitable landing area. Factors relating to the accident were: the airplane manufacture did not list the use of the installed electric boost pumps, nor did the pilot turn on the boost pump, once the engine lost power.

- 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.
