Probable cause

The pilot’s failure to maintain the runway heading during the approach in gusting crosswind conditions.

Findings · 5

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 ski-equipped airplane reported that, while on approach to a snow-covered airstrip, there was a quartering right gusting crosswind. He added that, about 100 ft above the ground, the right wing rose, and he attempted to correct to no avail. He added that the airplane was about 90° off of course to the left, and he chose to go between two trees. Subsequently, the left wing impacted a tree and separated from the airplane, and the airplane came to rest nose down. The airplane sustained substantial damage to the fuselage and left wing. The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation. The automated weather observation system about 9 nautical miles from the accident site reported that, about the time of the accident, the wind was from 280° at 12 knots, gusting to 21 knots. The pilot landed on runway 26.

He added that the airplane was about 90° off of course to the left, and he chose to go between two trees.
