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
Initial climb
First occurrenceThe 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
Total loss of engine power (non-mechanical)
Also codedOther events the NTSB coded in the sequence, such as a wire strike after a loss of power. Flight Findings uses them for its kinds of event. 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
Substantial

NTSB narrative

The certificated private pilot, with one passenger aboard, was departing from the Lake Hood Airstrip. As the airplane climbed to about 100 feet above the runway, all engine power was lost. The airplane landed in an area of tundra-covered marsh, just off the end of the departure runway. During the landing roll, the airplane's main wheels contacted the soft, boggy terrain, and the airplane nosed over. A postaccident inspection of the airplane's carburetor revealed about 10cc of rusty-colored fluid, along with clean fuel in the airplane's carburetor float bowl. The rusty-colored fluid tested positive for water, when tested with water detection paste. The fluid sample was released to the accident pilot at his request. The accident pilot reported that the fluid contained therapeutic levels of fluoride, commonly found in tap water. The pilot did not submit the test results report to the NTSB.

Probable cause

The pilot's inadequate preflight inspection to remove all contaminated fuel from the fuel system. A factor associated with the accident was an unsuitable terrain condition for 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: 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.
