Flight rulesThe regulations the flight operated under: in the US, Part 91 (general aviation), Part 121 (airlines), Part 135 (air taxi and commuter) and others; for flights abroad, the NTSB's coarser commercial or non-commercial code. Glossary
Part 91: General Aviation
Phase of flightThe stage of the flight when things started to go wrong: standing, taxi, takeoff, initial climb, en route, maneuvering, approach or landing. Glossary

Defining eventThe single coded event the NTSB judges best describes what happened (records from 2008 on). Older records name the first occurrence in the sequence instead. Glossary
Fuel contamination
DamageDestroyed: beyond practical repair. Substantial: damage that affects the structure, performance or handling and normally needs major repair. Minor: less than that. Glossary

NTSB narrative

The commercial pilot was on a Title 14, CFR Part 91, passenger flight in conjunction with his fish guiding business when the accident occurred. The pilot reported that he was flying about 700 feet above ground level in his float-equipped, single-engine airplane, when he began transferring fuel from the auxiliary fuel tank to the main fuel tank, and the engine lost power. After a failed attempt to restart the engine, he said he was forced to land the airplane on the tundra. The pilot said there were no known mechanical problems with the airplane prior to the accident. He further reported that it had been raining for several days, and he should have sumped the fuel tanks prior to takeoff. He also stated that he should have initiated the fuel transfer at a higher altitude over terrain that was suitable for landing. He said the float attachments and the fuselage were damaged during the accident.

Probable cause

A loss of engine power during cruise flight due to water in the fuel, and the pilot's inadequate preflight inspection.

  • 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, coordinates. 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.
