Sequence of events

The events NTSB coded, in order, by phase of flight. The defining event is the one that best describes the accident. Under each, the cases with the same event anywhere in their sequence.

Analysis

The solo student pilot reported that, after touchdown, she applied too much right rudder and then overcorrected by applying too much left rudder. The airplane then veered left and exited the runway. The right wing struck a windsock pole, crossed a ditch, and ground looped before coming to a stop upright. The airplane sustained substantial damage to the right wing, engine mount, and the left forward side of the fuselage. The flight instructor reported that there were no preaccident mechanical malfunctions or failures with the airplane that would have precluded normal operation.
