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.

Probable Cause and Findings

The student pilot's loss of directional control during landing, which resulted in a runway excursion, collision with a pole, and a subsequent ground loop.

    1. We had a female that took 30 hours to solo, she would get scared a lot so it took her more time to gain the confidence, she's done well, never did this though....
