NTSB narrative

THE FLIGHT HAD LANDED AT THE 5,600-FT LEVEL OF RUTH GLACIER FOR A 20 MIN TOURIST STOPOVER. ANOTHER FLIGHT, FLOWN BY A COMPANY SENIOR PILOT, ALSO HAD LANDED. THE SENIOR PILOT NOTICED A FUEL TANK FILLER CAP HANGING LOOSE ON THE ACCIDENT AIRPLANE, AND THE TWO PILOTS MEASURED THE FUEL IN THE TANKS. ONE TANK WAS FOUND EMPTY. THE PILOTS DETERMINED THAT THE AIRPLANE SHOULD BE FLOWN OFF THE GLACIER 'TO VERIFY THE FUEL LEVEL ON THE GAUGES IN LEVEL FLIGHT ATTITUDE, AND THAT IF HE (THE ACCIDENT PILOT) HAD ANY DOUBT ABOUT SUFFICIENT FUEL QUANTITY, TO RETURN (TO THE GLACIER) AND WE'D BRING HIM FUEL.' ABOUT 3 MIN AFTER TAKEOFF THE ENGINE QUIT AND THE FLIGHT MADE A CRASH LANDING AT THE 2,800-FT ELEVATION. THE PASSENGERS STATED THAT THE PILOT TOLD THEM TO 'TIGHTEN (OR FASTEN) YOUR SEATBELTS' DURING THE ENGINE-OUT DESCENT. NO PASSENGER COULD RECALL KNOWING THAT IMPACT WAS IMMINENT. THE RIGHT TANK WAS FOUND EMPTY, AND THE LEFT TANK CONTAINED 2-5 GALS. A PASSENGER STATED THAT THE RIGHT TANK WAS INDICATING EMPTY ON THE TRIP TO THE GLACIER FROM TALKEETNA.

Probable cause

FUEL EXAUSTION DUE TO THE THE PILOT-IN-COMMAND'S FAILURE TO REFUEL. FACTORS IN THE ACCIDENT WERE: PRESSURE BY MANAGEMENT PERSONNEL AND LACK OF SUITABLE TERRAIN DURING 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: local date, investigation status. Values present in the bulk record are kept.
  • The date is the local date; the NTSB stores the UTC date 1993-07-21.
