- 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
- Total loss of engine power (non-mechanical)
- 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 AIRPLANE EXPERIENCED A LOSS OF POWER IN BOTH ENGINES SHORTLY AFTER TAKEOFF. A FORCED LANDING WAS SUBSEQUENTLY MADE IN A FIELD; THE AIRPLANE COLLIDED WITH A DITCH DURING ROLLOUT. THE INSTRUCTOR PILOT REPORTED THAT BOTH ENGINES HAD MADE A 'POPPING NOISE' WHEN THEY LOST POWER. POST-CRASH EXAMINATION OF THE AIRPLANE REVEALED NO EVIDENCE OF ANY PRE-EXISTING MECHANICAL PROBLEMS. DURING A SUBSEQUENT ENGINE TEST-RUN ATTEMPT, BOTH ENGINES STARTED NORMALLY AND DEVELOPED POWER. THE RIGHT-ENGINE RUN WAS LIMITED TO 55% POWER DUE TO AIRPLANE DAMAGE. THE LEFT-ENGINE WAS RUN UP TO FULL POWER WITH NO PROBLEMS. DURING THE LEFT-ENGINE RUN-UP, FUEL TO THE ENGINE WAS SHUT OFF; AFTER ABOUT 30 SECONDS, THE ENGINE BEGAN TO MAKE A POPPING NOISE AND LOST POWER.
Probable cause
THE FAILURE OF THE INSTRUCTOR PILOT TO ENSURE THAT THE ENGINE FUEL SELECTOR VALVES WERE PROPERLY POSITIONED PRIOR TO TAKEOFF, WHICH LED TO FUEL STARVATION AND A LOSS OF ENGINE POWER DURING TAKEOFF.

- 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.
