What happened
While approaching the airport, the pilot monitored the ASOS frequency and noted winds of 12 knots from 120 degrees. The airport features a single asphalt runway, 03-21, which at the time of the approach presented a 90-degree crosswind.
The pilot performed a touch-and-go landing on runway 03 before turning to land on runway 21. During the landing roll, the aircraft swerved to the left. The pilot attributed this movement to either a possible gust of wind or an insufficient rudder correction. In response, the pilot applied hard right rudder, which caused the airplane to undergo a rapid turn to the right. The pilot was unable to counter this motion, and the left wing struck the runway, resulting in damage to the main spar.
The aircraft involved was not injured, though the impact caused structural damage.
