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 was on a solo cross-country flight when the accident occurred. The airplane reportedly touched down on the runway centerline then gradually veered toward the right side of the runway. The airplane nosed over after contacting a hard packed snow pile at the edge of the runway. The local winds reported 5 minutes after the accident were from 260 degrees at 13 knots gusting to 18 knots. The nose over resulted in substantial damage to the left wing spar and ribs.
