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 student pilot reported that, during the first solo landing, the glider was "not straight" for the flare, and she attempted to correct with right rudder. Subsequently, she overcorrected, and the glider veered right and struck a hangar. The glider sustained substantial damage to the fuselage and both wings. The student pilot reported that there were no preaccident mechanical failures or malfunctions with the glider that would have precluded normal operation.
