NTSB narrative
The private pilot had been receiving dual instruction in a gyroplane. During the takeoff portion of his first solo flight in the gyroplane, it began drifting toward the edge of the runway. Although the pilot aborted the takeoff and tried to realign the gyroplane with the runway, his control inputs resulted in the gyroplane rolling onto its side, resulting in substantial damage to the fuselage and rotor blades. According to the pilot, there was no indication of any preimpact mechanical malfunction or failure that would have precluded normal operation.
Probable cause
The pilot's failure to maintain directional control of the gyroplane during an aborted takeoff.

Source notes (4)
- 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.
