Aircraft involved

Probable cause & findings

The student pilot’s improper landing flare and loss of directional control and the flight instructor’s delayed remedial action resulted in a runway excursion and nose over.

Factual narrative

The flight instructor of the tailwheel equipped airplane reported that, during an instructional flight, the student pilot’s landing flare was not sufficient to preclude a bounce. The student added power, and the airplane turned to the left toward hangars. The flight instructor took over the flight controls and continued the left turn to avoid hangars. The airplane departed the runway surface into a field. The wheels became stuck in the muddy ground and the airplane nosed over and came to rest inverted. The wings and vertical stabilizer were substantially damaged. Source: NTSB Aviation Accident Database Retrieved: 2026-02-12
