- 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
- En route · cruise
- 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
- Loss of engine power
- 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
- Substantial

NTSB narrative
THE FLT DEPARTED USING FUEL FROM THE MAIN FUEL TANKS TO SUPPLY THE ENG AND CLIMBED TO ALT. THE PLT THEN UTILIZED THE FUEL FROM THE ELECTRICALLY DRIVEN AUX FUEL SYS BUT STATED THAT THE ENG QUIT 1 HR 15 MINUTES LATER. HE DETERMINED THAT THERE WAS A FAILURE OR MALFUNCTION OF THE ELECTRICAL SYS AND FUEL FROM THE MAIN TANKS WAS THEN USED TO SUPPLY THE ENG. THE ENG WAS RESTARTED. THE FLT DIVERTED TO AN ALTERNATE AND THE PLT ATTEMPTED TO SUPPLY FUEL TO THE ENG FROM THE AUX FUEL TANK BY TURNING ON THE SHUTOFF VALVE AND BOTH FUEL PUMPS BUT WAS UNSUCCESSFUL. THE ENG EVENTUALLY QUIT DUE TO FUEL EXHAUSTION IN THE MAIN FUEL TANKS. HE DITCHED THE ACFT NEAR AN ISLAND, SWAM TO IT, AND WAS RESCUED 26 HRS LATER. THE ACFT WAS NOT RECOVERED. HE FURTHER STATED THAT HE BELIEVES THAT THE FUEL PUMPS OVERLOADED THE ELECTRICAL SYS BUT IN RETROSPECT BELIEVES THE ALTERNATOR FAILED. THE AUX FUEL SYS INCORPORATES TWO ELECTRIC PUMPS BUT ONLY ONE IS TO BE USED FOR NORMAL OPERATION. THE SECOND PUMP IS TO BE USED ONLY FOR A FAILURE OR MALFUNCTION OF THE FIRST PUMP.
Probable cause
IMPROPER PLACEMENT OF THE BOOST PUMP SELECTOR BY THE PILOT IN COMMAND, AND ELECTRICAL SYSTEM FAILURE FOR UNDETERMINED REASONS. THIS RESULTED IN THE TOTAL LOSS OF ENGINE POWER DUE TO FUEL STARVATION.

- 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.
