However, the airplane impacted a snowbank on the right side of the runway and came to rest inverted. The airplane sustained substantial damage to the right wing lift strut. The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation. ## Factual narrative The pilot of the tailwheel-equipped airplane reported that, during landing on a snow- and ice-covered runway, he was unable to maintain directional control, so he attempted a go around.
