- 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
- Loss of control in flight
- 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
An FAA Inspector who witnessed the takeoff said the airplane 'lumbered' into the air. A witness on the river adjacent to the departure airport said his attention was drawn to the airplane by the increasing and decreasing engine noise and that nothing appeared wrong with the airplane. The pilot appeared to alternately lose and regain aircraft control. Approximately 400 feet above the ground, the engine accelerated to 'full throttle', the nose pitched up, and the airplane rolled inverted and descended into terrain. The engine did not stop producing power until the airplane was inverted and the nose had descended below the tail. Three weeks before the accident, the pilot logged .8 hours of dual instruction in a Cessna 152. Prior to that flight, the pilot had not flown in 14 months. The pilot had approximately 10 hours flight experience in the accident airplane. Prior to the accident flight, he had not flown the airplane in 2 years.
Probable cause
The pilot's failure to maintain adequate airspeed which resulted in an inadvertent stall spin and collision with terrain.

- 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.
