The pilot of the tailwheel and ski-equipped airplane reported that, while landing on an unimproved, snow-covered airstrip, the airplane landed hard and short of the airstrip due to windshear and wind gusts. The airplane slid on the right side and came to rest on the right wing and right horizontal stabilizer.
The airplane sustained substantial damage to the right wing.
The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.
The pilot reported that the wind condition was light and variable at 5 knots and was not gusting.
