NTSB Narrative Summary Released at Completion of Accident

According to the pilot, during touchdown on the runway, a gust of wind struck the right side of the airplane, and the left wing struck the ground. The airplane subsequently veered to the left and the pilot attempted to regain directional control with aileron inputs. The airplane departed the left side of the runway, struck an airport sign and came to rest in a grassy area. During the accident sequence, the airplane incurred substantial damage to the empennage and left wing. The pilot reported that there were no preexisting mechanical anomalies with the airplane. The pilot landed with a 14-knot quartering crosswind, gusting to 17 knots.
