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, while taxiing to park, a strong crosswind lifted the right wing and that the airplane then began to roll. He attempted to correct for the roll to no avail, and the airplane subsequently ran off the side of the taxiway and impacted a drainage ditch, which resulted in substantial damage to the fuselage and right lift struts. The student pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.
