Aviation Accident Summary GAA17CA187

Ruby, AK, USA

Aircraft #1

N72999

PIPER PA22

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.
