NTSB narrative
The flight instructor stated that he and his student were taking off from runway 22, and the experimental airplane had climbed to about 50 feet altitude when the flight controls stuck in the left position and the airplane descended in a spiral, impacting the ground. He stated that the engine was developing full power the whole time during the flight and that he did not stall the aircraft. An FAA inspector who responded to the accident site, said that witnesses told him they saw the airplane descend in a left spiral and that after impacting the ground the engine continued operating and had to be secured in order to remove the occupants. According to the inspector, the aircraft was destroyed and the extent of the damage precluded a determination of any flight control related anomalies.
Probable cause
The instructors in-flight loss of control due to the flight controls being jammed for undetermined reasons.

Source notes (5)
- 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.
- API snapshot SHA-256: 48ed637e365eb1af609e7599795db7befb7f1bb924c9f0e52e16ce8d9e958548; retrieved 2026-09-21T09:09:56.473Z.
- Corrected after a review of the NTSB narrative, which states these values explicitly: damage. The narrative states "According to the inspector, the aircraft was destroyed" after the airplane descended in a spiral and impacted the ground.
