The pilot of the ski-equipped CR-1 reported that, while on approach to a snow-covered airstrip in Altamont, N.Y., there was a quartering right gusting crosswind.
He added that, about 100′ above the ground, the right wing rose, and he attempted to correct, to no avail.
The airplane was about 90° off of course to the left, and he chose to go between two trees.
Subsequently, the left wing hit 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.
Probable cause: The pilot’s failure to maintain the runway heading during the approach in gusting crosswind conditions.
