NTSB narrative
The flight instructor, and the pilot receiving instruction, both reported that during tailwheel transition training, the airplane drifted to the right of the runway while performing a wheel-landing. They reported that left rudder was applied to counteract the drift, but the airplane did not respond as expected. The pilot receiving instruction stated that the airplane exited the runway, the left wheel caught the terrain, and the airplane nosed over. The airplane sustained substantial damage to the left wing, vertical stabilizer, and rudder. Neither pilot reported any mechanical failures or malfunctions of the airplane that precluded normal operation. Both pilots reported the wind condition as light and variable.
Probable cause
The pilots did not maintain directional control of the airplane during landing.

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.
