- 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

- 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
- Partial 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; Fuel starvation
- 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 pilot stated he added 9 gallons of automotive fuel to the left tank prior to the flight. He stated that this fuel was not filtered or strained prior to or during the refueling. While on downwind, the engine began to shutter. The pilot continued to troubleshoot the situation and was able to maintain engine power with full throttle only. He elected to land at an adjacent field. During the landing roll, he stated he was "unable to stop before the end of the field" and impacted a ditch. The airplane was substantially damaged. An examination of the airplane's systems revealed that the fuel filter was plugged.
Probable cause
the pilot's failure to strain the fuel prior to flight resulting in fuel starvation. Contributing to the accident was the loss of engine power due to the plugged fuel filter.

- 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.
