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 in the snow ski-equipped airplane reported that, during landing, just before touchdown, he noticed a rock sticking out of the snow near the intended touchdown point. He tried to change the airplane's course to the left, but the left ski contacted the snow when the airplane was not straight with the direction of travel, and the airplane bounced. The right ski then contacted the snow, and the right main landing gear strut failed. The right wing struck the ground, and the airplane came to rest. The airplane sustained substantial damage to the right wing spar. The pilot reported that there were no preaccident mechanical malfunctions or failures with the airplane that would have precluded normal operation.
