NTSB narrative

DURING A DAY CROSS-COUNTRY FLIGHT THE AIRPLANE EXPERIENCED A COMPLETE LOSS OF LEFT ENGINE POWER. NORMAL RESTART PROCEDURES WHICH INCLUDED A SELECTION OF THE CROSS-FEED POSITION FAILED TO RESTORE POWER TO THE LEFT ENGINE. THE PILOT DIVERTED TO AN EN ROUTE AIRPORT FOR A SINGLE ENGINE APPROACH AND LANDING. AS THE PILOT INITIATED A SINGLE ENGINE GO-AROUND, A COMPLETE POWER LOSS OCCURRED TO THE RIGHT ENGINE. THE AIRPLANE IMPACTED TREES AND TERRAIN OFF THE DEPARTURE END OF THE RUNWAY. INVESTIGATION REVEALED A BROKEN FUEL FITTING ON THE LEFT FUEL SELECTOR UNIT AND WORN THREADS ON A FUEL FITTING ON THE RIGHT ENGINE. THIS RESULTED IN THE FUEL STARVATION POWER LOSS TO BOTH ENGINES.

Probable cause

FUEL STARVATION INDUCED POWER LOSS ON FIRST THE LEFT ENGINE DUE TO A FAILED FUEL FITTING AND THEN THE RIGHT ENGINE DUE TO A WORN FUEL FITTING. A FACTOR WAS THE LACK OF SUITABLE TERRAIN FOR THE FORCED LANDING.

  • 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: e5f76e00e6604f04f7ce13546c828a9e9b3e3f57acc8350461e7da2673991980; retrieved 2026-09-23T03:54:52.984Z.
