NTSB narrative

PIREPS PROVIDED TO THE PILOT BY FSS PRIOR TO TAKEOFF INDICATED THAT FOG & LOW VISIBILITY HAD BEEN ENCOUNTERED ON THE PILOT'S ROUTE TO THE EAST, FORCING AIRPLANES TO RETURN TO NOME. IN ADDITION, AS THE FLIGHT TAXIED FOR TAKEOFF, THE PILOT WAS TOLD '... VFR IS NOT RECOMMENDED TO THE EAST...' THE AIRPLANE IMPACTED FLAT SNOW COVERED TERRAIN IN A STEEP LEFT WING DOWN ATTITUDE APRX 4 MI EAST OF THE DEPARTURE END OF THE RUNWAY. THE AREA WAS A TREELESS, SNOW COVERED FLAT COASTAL PLAIN BORDERED BY A SEA FROZEN WITH WHITE ICE. THE PILOT HAD RETURNED TO WORK 4/1 AFTER A 30-DAY SUSPENSION FOLLOWING A TAKEOFF ACCIDENT, AND WAS ASSIGNED ONLY TO CESSNA 207 'VFR ONLY' AIRPLANES. THE POI DID NOT DISCUSS THE EARLIER ACCIDENT OR THE PILOT WITH THE OPERATOR'S MANAGEMENT.

Probable cause

THE PILOT INITIATED VFR FLIGHT INTO INSTRUMENT METEOROLOGICAL AND WHITEOUT CONDITIONS. FACTORS WHICH CONTRIBUTED TO THE ACCIDENT WERE: INADEQUATE SUPERVISION OF THE PILOT BY THE COMPANY, INADEQUATE OVERSIGHT BY THE FEDERAL AVIATION ADMINISTRATION, THE PILOT'S SELF-INDUCED PRESSURE TO CONDUCT THE FLIGHT, AND THE EXISTING WEATHER CONDITIONS AND SNOW COVERED TERRAIN.

  • 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.
