NTSB narrative
The solo pilot departed from a gravel-covered airstrip. Witnesses reported that they saw the airplane make a left, 270-degree turn and eventually overfly the departure end of the airstrip. The airplane then climbed to about 300 ft above ground level, flew in a southeasterly direction over a nearby house, then began a climbing left turn. Witnesses said that the airplane pitched up, the left wing dropped, and the airplane descended vertically, nose first, disappearing behind a stand of tall trees. The airplane subsequently collided with a paved, rural roadway. A postcrash fire incinerated a large portion of the airplane's cockpit, left wing, and fuselage. A postaccident examination of the airframe and engine revealed no mechanical malfunctions or anomalies that would have precluded normal operation.
Given the lack of mechanical deficiencies with the airplane and engine, the witness statements, and the nature of the damage to the airplane, it is likely that the pilot inadvertently exceeded the airplane's critical angle-of-attack while maneuvering at a low altitude, which resulted in an aerodynamic stall and a loss of control.
Probable cause
The pilot’s failure to maintain adequate airspeed and his exceedance of the airplane’s critical angle-of-attack while maneuvering, which resulted in a stall at too low an altitude to allow recovery.

- 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.
