N4538F

The pilot of the wheel/ski-equipped airplane landed on a remote frozen snow-covered lake. While taxiing to parking, the right wheel/ski struck an area of ice overflow that was covered by snow. During the collision, the axle bolts on the right wheel/ski broke, which pivoted the airplane to the right, and the right wing struck the snow-covered ice. The airplane sustained substantial damage to the right wing. Other than the broken axle bolts, the pilot reported no preaccident mechanical problems with the airplane. In his written statement to the NTSB, the pilot reported that flat light conditions on the snow-covered lake contributed to his inability to see the ice overflow.
