- 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
- 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 starvation; Stall/spin
- DamageDestroyed: beyond practical repair. Substantial: damage that affects the structure, performance or handling and normally needs major repair. Minor: less than that. Glossary
- Destroyed
Cause areas
- Fluid, fuel › Starvation
- Pilot in command › Airspeed, not maintained
- Pilot in command › Fuel tank selector position, improper

NTSB narrative
Witnesses reported the airplane had just taken off and was climbing to the east when they heard the engine stop. The witnesses observed the airplane turn around towards the airport, depart controlled flight, and impact the ground near the southeast corner of the airport. The witnesses also said they heard the engine sputter as the airplane was attempting to return to the airport. An examination of the airplane showed witness marks in the cockpit floor panel consistent with the fuel selector valve handle being in the "Off" position at impact. An examination of the engine intake valves and spark plugs showed evidence consistent with operating the engine with a lean mixture. On removal of the number 3 cylinder bottom spark plug, the smell of alcohol, consistent with the use of starter fluid, was evident. No evidence of fuel was found in the carburetor. No other anomalies were found. FAA toxicology testing of the pilot showed concentrations of Ephedrine, Pseudoephedrine, and Azacyclonol in urine.
Probable cause
the pilot's improper preflight planning/decision resulting in the fuel selector positioned improperly and fuel starvation, and his failure to maintain adequate airspeed. A factor contributing to the accident was the low altitude.

- 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.
