NTSB narrative
The flight instructor was conducting a biennial flight review with the commercial pilot. A witness reported that she observed the airplane heading in a southeast direction at an altitude of about 350 feet. The witness stated, "The plane began to execute a right hand turn, and then rolled over so the top of the plane was facing east and the nose was pointing down. I then saw the nose barely try to pull up, and I waited for it to come up, but it never did." A second witness, who was a first responder and was walking in close proximity to the accident site reported hearing the ground impact behind him, but was unaware that it was an airplane that had crashed, as he did not hear any engine noise prior to the impact. The witness reported smelling fuel and observing a pool of fuel forming under the wings after reaching the wreckage. Another first responder reported that he smelled a "strong odor" of aviation fuel as he approached the wreckage. GPS data revealed that the airplane had performed a 4-turn spiral over the airport prior to the descent to ground impact. Examination of the wreckage disclosed impact signatures and ground scars consistent with a stall/spin. A post accident examination of the engine and airframe revealed no anomalies that would have precluded normal operation.
Probable cause
The pilot's failure to maintain adequate airspeed while maneuvering, which resulted in an aerodynamic stall/spin.

- 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.
