During the landing on runway 17 a gust of wind pushed the tailwheel equipped airplane to the left. The pilot attempted to correct back to the runway centerline; the airplane exited the right side of the runway and spun 180 degrees. The left wing impacted the ground and sustained substantial damage. The pilot reported no mechanical malfunctions with the airplane and stated that he lost control during landing. Around the time of the landing, the automated weather station reported the wind from 260 degrees at 18 knots, gusting to 24 knots. A review of the airplane's flight manual revealed the maximum demonstrated crosswind velocity was 17 knots.
