Analysis

The pilot planned to land at a Bureau of Land Management backcountry landing strip he had previously visited over 100 times. After completing multiple low passes to assess the snow depth and overall conditions of the landing area, he executed a soft field landing in a 3-point, full stall attitude. During the rollout, the drag from the snow was greater than expected and he was unable to maintain control. The airplane nosed over at low speed and came to rest inverted. The vertical stabilizer, rudder, and right-wing struts sustained substantial damage. The pilot reported that there were no preaccident mechanical malfunctions or failures with the airplane that would have precluded normal operation.
