NTSB narrative
The airplane ground looped during landing and came to rest inverted. The pilot undergoing instruction (PUI) had recently purchased the airplane. He and the certified flight instructor (CFI) departed from their airport of origin after completing one traffic pattern to a successful full stop landing. The CFI was present for insurance requirements and was also providing instruction. They proceeded to another airport nearby and setup for a landing on runway 25. The approach and initial touchdown were unremarkable. During the roll out, the PUI reduced the power and the airplane began to veer to the left. The PUI overcorrected, overpowering the CFI, and the airplane turned to the right. The left wing contacted the ground and the airplane came to rest inverted. The PUI did not report any mechanical malfunctions with the airplane prior to the accident. He had approximately 347 hours total flight time, 40 hours were in tailwheel equipped airplanes, and 5 of those hours were in the accident airplane. According to the airport manager, the winds were about 6 knots, blowing directly down the runway.
Probable cause
the pilot undergoing instruction's overcontrol of the aircraft by his excessive use of the rudder control and failure to maintain directional control of the airplane during landing, which resulted in a ground loop. Contributing factors to the accident were the pilot undergoing instruction's lack of experience in the airplane and his overpowering the CFI on the controls.

- 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.
