The pilot of the wheel-equipped airplane reported that, while landing on an unimproved snow-covered airstrip, he misjudged the surface condition. He added that, as the nose gear touched down the wheel broke through the snow, turned sideways, and the airplane nosed over.

The airplane sustained substantial damage to the front windshield and both wings.

The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.
