- 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 · descent
- 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 (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 exhaustion
- DamageDestroyed: beyond practical repair. Substantial: damage that affects the structure, performance or handling and normally needs major repair. Minor: less than that. Glossary
- Substantial
Cause areas
- Pilot in command › Fuel consumption calculations, poor

NTSB narrative
AFTER REFUELING THE ACFT WITH A REDUCED FUEL LOAD THE NON-INSTRUMENT RATED PLT TOOKOFF FOR HIS DESTINATION. UPON ARRIVAL HE ADDED A REDUCED AMOUNT OF FUEL BASED ON HIS ORIGINAL CALCULATIONS. ON HIS RETURN NIGHT FLT THE FOLLOWING NIGHT HE RECEIVED A WX BRIEFING, FILED A VFR FLT PLAN AND DEPARTED FOR HIS HOME ARPT. WHEN APPROACHING THE DESTINATION ARPT HE DETERMINED THE WX WAS BELOW VMC AND ELECTED TO LAND AT AN ENROUTE ARPT. DURING THE DESCENT THE ACFT'S ENGINE SUSTAINED A TOTAL LOSS OF POWER DUE TO FUEL EXHAUSTION. THE PLT STATED THAT THE AIRPLANE ENTERED GND FOG PRIOR TO COLLIDING WITH AN UNOCCUPIED HOUSE AND A PROPANE TANK. EXAMINATION OF THE AIRPLANE DID NOT DISCLOSE ANY EVIDENCE OF FUEL IN THE FUEL TANKS OR ON THE GROUND ADJACENT TO IT.
Probable cause
THE PILOT-IN-COMMAND'S IMPROPER PREFLIGHT PLANNING PREPARATION AND FUEL CONSUMPTION CALCULATIONS RESULTING IN A TOTAL LOSS OF ENGINE POWER DUE TO FUEL EXHAUSTION, FORCED LANDING AND IN FLIGHT COLLISION WITH A RESIDENCE.

- 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: local date, investigation status. Values present in the bulk record are kept.
- The date is the local date; the NTSB stores the UTC date 1991-07-14.
