Aircraft involved
Probable cause & findings
The student pilot's failure to maintain directional control and his use of excessive braking while taxiing.
Factual narrative
The flight instructor and the student pilot who was on the controls, were taxiing for departure when the airplane started to veer to the right of the taxiway centerline. In an attempt to correct the directional movement, the student pilot applied the brakes quickly. The flight instructor reported that he could not intervene quick enough before the airplane nosed-over and came to rest inverted on the taxiway. The airplane sustained substantial damage the right wing and vertical stabilizer. The flight instructor reported no mechanical malfunctions or failures prior to the accident that would have precluded normal operation of the airplane.
