NTSB narrative
THE AIRPLANE BECAME MISSING WHILE ON AN IFR FLIGHT IN INSTRUMENT CONDITIONS FROM YAKUTAT, ALASKA TO ANCHORAGE, ALASKA. THERE WAS NOT FURTHER RADIO COMMUNICATION WITH THE AIRPLANE AFTER THE PILOT REPORTED LEVEL AT HIS ASSIGNED ALTITUDE OF 12,000 FEET MSL. AFTER LISTENING TO FAA AIR TRAFFIC CONTROL TAPES OF COMMUNICATIONS WITH THE PILOT, HIS WIFE STATED THAT SEVERAL MINUTES AFTER THE POINT WHICH THE FAA SAID WAS THE LAST TRANSMISSION FROM THE PILOT, SHE HEARD HER HUSBAND SAY SOMETHING ABOUT '6,000' AND 'ICING CONDITIONS'. AN ENHANCEMENT EXAMINATION OF THE TAPES BY THE FBI LABORATORY FAILED TO CONFIRM THIS INFORMATION. AIRCRAFT DAMAGE AND OCCUPANT INJURIES ARE PRESUMED.

Source notes (5)
- 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 1992-05-04.
- API snapshot SHA-256: 6612e2ee4d2ee79687d90173c96a0c63b5119c95670539107cd89d64209bb0e0; retrieved 2026-09-21T01:13:10.266Z.
- Corrected after a review of the NTSB narrative, which states these values explicitly: departure. The narrative states the airplane went missing "ON AN IFR FLIGHT IN INSTRUMENT CONDITIONS FROM YAKUTAT, ALASKA TO ANCHORAGE, ALASKA"; the departure was not recorded.
