Probable cause
The pilot’s failure to maintain directional control while landing in flat light conditions on a hard-packed snow-covered landing area.
NTSB analysis
The pilot of the tailwheel, ski-equipped airplane reported that, while landing off airport in flat light conditions, he was unable to maintain a good visual reference of the hard-packed snow-covered landing area. After touchdown, the airplane drifted off the hard-packed snow, and the left ski sunk in softer snow. He increased power and attempted to recover with "hard right control" to no avail. The airplane's left ski struck a snow-covered tank.
The airplane sustained substantial damage to the 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.
