NTSB investigators used data provided by various entities, including, but not limited to, the Federal Aviation Administration and/or the operator and did not travel in support of this investigation to prepare this aircraft accident report.

The pilot of the wheel/ski-equipped airplane reported that, after landing on skis and during the taxi on hard-packed snow, a wind gust 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 revealed that, about 13 minutes after the accident, the wind was from 360° at 12 knots, gusting to 20 knots.

The National Transportation Safety Board determines the probable cause(s) of this accident as follows:
  • The pilot’s failure to maintain directional control during the taxi on skis on hard-packed snow in gusting wind conditions.
