The airplane was substantially damaged during a runway excursion while landing at 1446 Eastern time. Visual conditions prevailed; there were no injuries. The pilot later reported a right crosswind during approach and landing. He stated the landing was normal, on centerline and that touchdown was at the 1000-foot runway markings. As the nose lowered the aircraft veered sharply to the left. He reportedly held full right rudder and right aileron but the aircraft did not respond. The aircraft departed the left side of the runway, struck a runway light and came to rest in the muddy grass area next to the runway pavement. A post-accident inspection did not reveal any anomalies with the nose wheel steering and rudder control systems.
