- 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
- Loss of engine power
- 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
- 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

NTSB narrative
The airplane was observed in level flight with the engine '...sputtering, cutting out....' The 'left wing dropped, then the right wing dropped, and the airplane rolled into a spin to the left.' As the airplane rotated toward the ground, witnesses described the 'motor running wide open.' Fibrous foreign material was found on all fuel system screens. The fuel system components were bench tested and the metering unit screen was also tested during an exemplar engine run. All testing was within manufacturer specifications. Fuel samples from the refueling locations tested within the standard specifications for aviation gasoline 100LL. The fuel metering screen foreign material and the bladder fuel cells contained types of fibers; however, a definitive source of the fibers could not be determined. Maximum gross weight (3,600 lbs) CG range is 82.1 inches to 83.8 inches. Weight at the time of the accident was calculated at 3466.5 lbs with a CG of 87.00 inches.
Probable cause
an engine surge for undetermined reasons, and the pilot's failure to maintain airspeed resulting in an inadvertent stall/spin. A factor was the aft center of gravity.

- 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.
