NTSB narrative
The airplane nosed over following a collision with a snow bank while landing. The purpose of the flight was for the certified flight instructor (CFI) to provide tailwheel training to a private pilot who was taking a tailwheel transition course. The CFI stated the student made the first landing. The CFI stated he then demonstrated a wheel landing. The student made two more landings with little assistance. The accident occurred on the student's fourth landing of the flight. The CFI stated the student landed on the main gear and after the tailwheel came down the airplane "turned slightly left of centerline." He stated the student overcorrected and the airplane veered abruptly to the right. The CFI stated he applied full left rudder, but it was too late. The airplane ground looped, struck a snow bank on side of the runway, and nosed over.
Probable cause
The CFI's delay in applying remedial action which resulted in a loss of directional control of the airplane. Factors associated with the accident were the student's excessive application of rudder and the snow bank which the airplane contacted.

- 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.
