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

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

NTSB narrative

According to the pilot, the engine started to run rough, and then lost power, while in cruise flight at 6,500 feet MSL. The pilot attempted to land at a nearby airport; however, he subsequently landed short of the airport in a field approximately one mile southeast of the airport. During the landing roll, the airplane impacted a fence and fence posts, which resulted in leading edge damage to one wing and structural damage to both wing struts. The engine was examined by an FAA inspector, the aircraft owner, and a representative from the engine manufacturer at an local FBO. The contents of the fuel system were examined, and evidence of fuel contamination was found. The fuel in the tanks was yellow/straw in color and lacked the appearance of 100LL fuel; however, no diesel or jet fuel was detected. New spark plugs were installed, and the airplane was defueled and serviced with fresh 100LL fuel. The engine was started, and it operated normally through the normal operating range.

Probable cause

loss of engine power due to fuel contamination. The lack of suitable terrain for a forced landing was a related factor.

  • 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.
