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

AFTER ABOUT 1 HOUR AND THIRTY MINUTES OF FLIGHT, A TOTAL LOSS OF POWER OCCURRED IN THE LEFT ENGINE. WHILE THE PILOT WAS DIAGNOSING THE PROBLEM, THE RIGHT ENGINE LOST POWER. THE PILOT DID NOT SWITCH THE FUEL TANK SELECTORS TO THE OUTBOARD TANKS, AND EXECUTED AN EMERGENCY LANDING ON THE DESERT TERRAIN. DURING THE LANDING ROLL, THE AIRPLANE COLLIDED WITH A FENCE AND NOSED OVER. AN EXAMINATION DISCLOSED THAT THE OUTBOARD FUEL TANKS CONTAINED FUEL; THE INBOARD FUEL TANKS WERE EMPTY.

Probable cause

FUEL STARVATION DUE TO THE IMPROPER FUEL MANAGEMENT (POSITIONING OF THE FUEL SELECTOR) BY THE PILOT, AND HIS IMPROPER EMERGENCY PROCEDURES. THE PILOT'S LACK OF EXPERIENCE IN THIS MAKE AND MODEL OF AIRCRAFT WAS A RELATED 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: local date, investigation status. Values present in the bulk record are kept.
  • The date is the local date; the NTSB stores the UTC date 1991-03-30.
  • API snapshot SHA-256: de335f2d58bfd7e0594681f211da53ea19746f8d7855171287cfefc9c0d694f3; retrieved 2026-09-21T23:37:53.844Z.
