Aircraft involved

Probable cause & findings

The pilot’s failure to maintain directional control during the taxi on skis on hard-packed snow in gusting wind conditions.

Factual narrative

The pilot of the wheel-ski equipped airplane reported that after landing on skis, during the taxi on hard packed snow, a gust of wind pushed the airplane and the left wing impacted a parked, unoccupied airplane. The airplane sustained substantial damage to the left wing and left wing lift strut. The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation. A review of recorded data from the automated weather observation station located on the airport reported that about 13 minutes after the accident the wind was 360° at 12 knots, gusting 20 knots.
