The pilot of the tailwheel-equipped airplane reported that, during landing, after a stabilized approach, the airplane touched down on the main gear first for a wheel landing. The airplane bounced twice and shortly before the tail settled on the ground, the "crosswind increased causing the aircraft to weathervane to the left." He added that, he increased left aileron and right rudder to keep the airplane on the gravel airstrip; however, the "wind gust then all but stopped as the tailwheel settled to the ground causing the aircraft to turn rapidly to the right." He further added that, he increased left rudder and brake, but the main gear started to depart the gravel airstrip and enter the softer shoulder. The "tail swung to the left of the aircraft direction of travel" and he was unable to correct the continued tightening right turn. Subsequently, the airplane rolled onto the left wing and left horizontal stabilizer and came to rest on the main landing gear. The airplane sustained substantial damage to the left wing and left horizontal stabilizer The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation. The pilot reported the wind at the accident site, about the time of the accident, as variable at 0 to gusting 10 knots. The pilot landed to the northeast.
