Analysis

The pilot was taking off in his tundra tire equipped airplane on a private, ice-covered, gravel runway. He stated that during the takeoff roll ruts in the ground caused him to lose control of the airplane. The airplane struck a snow berm and sustained substantial damage to the right wing and fuselage. The pilot stated that there were no preaccident mechanical anomalies with the airplane that would have precluded normal operation.
