NTSB narrative
The certificated flight instructor was giving landing instruction to a pilot-rated dual student during a public use flight at an off airport landing site. During the landing roll, the student applied the brakes excessively, and the airplane nosed over. The flight instructor indicated he felt his expectations and the outcome of the maneuver had not been properly communicated to the student, and that prior to the accident, there were no known mechanical problems with the airplane. The airplane sustained substantial damage to the vertical stabilizer, wings, lift-struts, and windshield.
Probable cause
The flight instructor's inadequate supervision of the dual student during the landing roll, which resulted in the dual student applying the brakes excessively, and the airplane nosing over. A factor associated with the accident was the excessive braking by the dual student.

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: 49f669460278e8699239c3643675d2b28957d10e8b9f13d2ba71e69c8a20ed95; retrieved 2026-09-22T05:19:01.971Z.
- Corrected after a review of the NTSB narrative, which states these values explicitly: operation. The narrative states the flight instructor was giving landing instruction "during a public use flight" (operator U.S. National Park Service); the flight was a public aircraft operation, not Part 91 general aviation.
