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 pilot of the tailwheel-equipped airplane reported that, upon landing, the airplane bounced twice and started to veer left. He immediately applied power to go around, but the main landing gear struck a snowbank, and the airplane nosed over. The airplane sustained substantial damage to the left and right wings. The pilot reported that there were no preimpact mechanical failures or malfunctions with the airplane that would have precluded normal operation.
