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 (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 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

  • Fluid, fuel › Exhaustion
  • Pilot in command › Aircraft preflight, inadequate

NTSB narrative

ACCORDING TO A WITNESS, THE ENG BEGAN RUNNING ROUGH AS THE ACFT WAS CLIMBING AFTER TAKEOFF, BUT IT BEGAN RUNNING NORMALLY AFTER THE NOSE WAS LOWERED. HOWEVER, AS THE PLT WAS MANEUVERING TO RETURN TO THE ARPT, THE ENG LOST POWER AGAIN. SUBSEQUENTLY, THE ACFT WAS DAMAGED DURING A FORCED LANDING ON UNPREPARED TERRAIN. NO FUEL WAS FOUND IN THE ACFT AFTER THE ACDNT & NO FUEL SPILL WAS EVIDENT.

Probable cause

INADEQUATE PREFLIGHT OF THE AIRCRAFT BY THE PILOT WHICH RESULTED IN FUEL EXHAUSTION DUE TO AN INADEQUATE SUPPLY OF FUEL. THE TERRAIN CONDITION WAS CONSIDERED TO BE A FACTOR.

  • 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.
  • API snapshot SHA-256: 0e75f412cde3a1386947a6657016b1158d7f593d8ea40c0f5f4a28f504a909b4; retrieved 2026-09-21T15:54:29.358Z.
