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, during landing in a crosswind, he planned to touch down 2 ft past the beginning of the compacted, snow-covered, private airstrip. He added that, "in order to perform [the short field landing, he] chose to ride the tires just over the terrain until touchdown." He reported further that, after the front main landing gear touched down, a wind gust picked up the right wing, the left tire sank in the snow, and the airplane decelerated and then nosed over. The airplane sustained substantial damage to the left wing. The pilot reported that there were not preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation. The pilot reported that the wind at the accident location, about the time of the accident, was from 230° at 9 knots, gusting to 15 knots. The pilot was landing the airplane to the southwest on a 210° heading.

Factual narrative

He added that, "in order to perform [the short field landing, he] chose to ride the tires just over the terrain until touchdown". After the front main landing gear touched down, a "gust of wind" picked up the right-side wing, the left tire sank in the snow, and the airplane decelerated and nosed over. The airplane sustained substantial damage to the left wing. The pilot reported that there were not preaccident mechanical failures or malfunctions that would have precluded normal operation. The pilot reported the wind at the accident location, about the time of the accident as wind 230° at 9 knots, gusting to 15 knots. The pilot was landing to the southwest, heading 210°.
