The pilot reported a normal flight to the accident airport. He set up for landing in the 50-degree crosswind with no unusual drift noted on final approach, followed by a normal landing. The pilot stated that the next thing he recalled the left wing dropped, and the airplane was skidding to the right across the runway and impacting a runway light. After coming to a stop he obtained permission to taxi the airplane to a tie down spot. The pilot reported no mechanical problems with the airplane. According to the Federal Aviation Administration (FAA) inspector, the airplane spun round to the right, which caused structural damage to the left wing and elevator.
