NTSB narrative

THE PILOT COMMUNICATED THAT THE WEATHER IN THE MOUNTAIN PASS AHEAD DID NOT LOOK FAVORABLE AND WOULD RETURN TO THE REMOTE CAMP IF UNABLE TO MAKE IT THROUGH. A WITNESS REPORTED THE HIGH TERRAIN WAS OBSCURED IN CLOUDS. SEARCH AIRCRAFT LOCATED WRECKAGE NEAR 7000 FOOT LEVEL OF TOP OF PASS IN A 20 DEGREE UPSLOPING RAVINE. A POST CRASH FIRE DESTROYED THE AIRCRAFT. THE WRECKAGE WAS NOT RECOVERED.

Probable cause

THE PILOT IN COMMAND'S ATTEMPTED VFR FLIGHT INTO IMC CONDITIONS. FACTORS CONTRIBUTING TO THE ACCIDENT WERE THE HIGH TERRAIN AND THE OBSCURATION.

  • 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 1993-08-30.
  • API snapshot SHA-256: c7e93f2022d1b921ae6d2c8ef8c6bae0dfe22070ca82acf711f13c48432cacdb; retrieved 2026-09-21T00:24:26.946Z.
