Aircraft involved

Probable cause & findings

THE PILOT'S FUEL MISMANAGEMENT IN NOT HAVING SUFFICIENT FUEL TO REACH HIS DESTINATION.

Factual narrative

THE PILOT REPORTED THAT HE WAS ATTEMPTING TO COMPLETE A FLIGHT FROM ANCHORAGE TO MCGRATH AND RETURN WITHOUT REFUELING. HE TOPPED OFF THE FUEL TANKS IN ANCHORAGE PRIOR TO DEPARTURE. PRIOR TO LEAVING MCGRATH, HE VISUALLY INSPECTED, BUT DID NOT STICK THE TANKS. HE THOUGHT THE FUEL TANKS WERE SLIGHTLY MORE THAN ONE-HALF FULL. APPROXIMATELY 10 MILES FROM ANCHORAGE THE ENGINE SPUTTERED AND EVENTUALLY STOPPED. A FORCED LANDING WAS MADE IN THE TUNDRA. THE PILOT LATER STATED THAT IT IS MOST LIKELY THAT THE ENGINE QUIT DUE TO FUEL EXHAUSTION. Source: NTSB Aviation Accident Database (Pre-2008 Archive) Retrieved: 2026-02-12
