NTSB narrative

A WITNESS REPORTED THAT THE AIRPLANE MADE A LOW PASS OVER THE UNLIGHTED AIRSTRIP IN DARK NIGHT CONDITIONS. THE WITNESS THOUGHT THAT IT WAS LANDING AT THAT TIME, HOWEVER, THE AIRSPEED WAS TOO FAST. AT THE END OF THE AIRSTRIP, THE AIRPLANE SUDDENLY PULLED UP AND MADE A SHARP LEFT TURN. THE AIRPLANE DESCENDED BEHIND A SMALL HILL AND SHORTLY THEREAFTER, FLAMES WERE VISIBLE. DURING THE POST CRASH INVESTIGATION, IT WAS NOTED THAT THE AIRPLANE COLLIDED WITH THE TERRAIN IN A NOSE DOWN AND LEFT WING LOW ATTITUDE. NO EVIDENCE WAS FOUND TO INDICATE A MECHANICAL FAILURE OR MALFUNCTION.

Probable cause

THE PILOT'S POOR IN-FLIGHT PLANNING/DECISION AND HIS FAILURE TO MAINTAIN AIRSPEED ABOVE A STALL.

  • 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 1993-09-22.
  • API snapshot SHA-256: f303626e57ea67cf2d6ecb14afcbd0e7b75805ff4bcf62aa31fb9532b81ffd63; retrieved 2026-09-21T00:22:54.226Z.
