NTSB narrative
The flight instructor (CFI) reported that on roll-out from a touch-and-go landing, the student looked down for the flap handle as he raised the flaps. During this process, the aircraft started to go to the right. The CFI stated, 'I tried to correct to the left using rudder and aileron, then also using power, but the plane ground looped to the right and the left wing dipped, striking the ground.' Additionally, the CFI indicated that there were no mechanical malfunctions with the aircraft before the accident.
Probable cause
failure of the student pilot to maintain directional control of the aircraft, and the flight instructor's inadequate supervision of the flight. The student's diverted attention was a related factor.

- 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.
