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 reported that, on the day of the accident, about 6 inches of fresh snow covered the runway's surface. He added that, during the approach to land, he lined up with what he thought was the appropriate runway, slowed the airplane, and applied flaps. Upon touchdown, the nosewheel "dug" into the snow, and the airplane nosed over. The pilot reported that he had unintentionally landed on the ski strip, which had accumulated about 2 ft of snow, and not the intended runway. The airplane sustained substantial damage to the left wing.
