- 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
- Approach · VFR pattern base
- 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
- Destroyed
Cause areas
- Pilot in command › Airspeed, not maintained
- Pilot in command › Stall/spin, inadvertent

NTSB narrative
A witness observed the airplane on a "close and tight" downwind leg for the runway at an altitude of approximately 400 feet above ground level. While on the downwind leg, the airplane was in "slow flight in a nose high attitude." The witness observed the airplane enter a steep left turn from the downwind to base leg, and "at that time, I thought it was going to stall and spin.". The airplane's wings rolled level and the airplane began to porpoise. During the porpoise, the witness noted hearing changes to the engine power. The airplane then entered another steep left turn with the wings almost vertical to terrain. "I could see the entire top of the plane during the turn and the engine RPM was increased dramatically, maybe to full power." The witness observed the "nose pitch up and the right wing stall...as if a falling leaf." Subsequently, the airplane entered a spin (1.5 rotations) and impacted terrain. The witness stated that during his observation "the engine was operating under power the entire time." The airplane came to rest inverted in grass terrain adjacent to a drainage ditch approximately 1/2 mile from the threshold of the runway and was destroyed by post impact fire. Examination of the airframe and engine revealed no anomalies.
Probable cause
the pilot's failure to maintain airspeed resulting in an inadvertent stall and impact 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, 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.
