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

According to the student pilot, during the solo flight while on final approach, he thought the airplane was on glidepath, but realized after the accident that the airplane was "low." Subsequently, the right main landing gear struck a snowbank at the end of the runway, which resulted in the right main landing gear being bent aft. The student pilot proceeded to land the airplane; however, upon landing it veered off the right side of the runway into another snowbank. A postaccident examination of the airplane revealed substantial damage to the firewall. The student pilot reported no preimpact mechanical malfunctions or failures with the airplane that would have precluded normal operation.
