Aircraft involved
Probable cause & findings
The student pilot's use of excessive brakes during taxi, which resulted in a loss of aircraft control.
Factual narrative
The solo student pilot was taxiing in a tailwheel equipped airplane for takeoff on the second leg of a solo cross-country flight. During the taxi, she noticed she was approaching a hold short line and applied the brakes to stop at the line. She said while depressing the heel brakes her foot became wedged and she pressed the brake harder than necessary. The tail of the airplane came up, dropping the nose to the ground. The airplane hesitated with its tail in the air for a moment, and then fell over on its back. The pilot reported no preimpact mechanical anomalies with the airplane that would have precluded normal operation. The airplane sustained substantial damage to the vertical stabilizer, rudder, and the fuselage.
