Analysis

The pilot of the tailwheel-equipped airplane reported that, during the fourth landing on a rural runway, the airplane touched down hard, bounced, and veered left. The pilot attempted to correct with opposite rudder; however, the airplane continued left into a field and ground looped to the left. The right wing impacted the ground, and the right main landing gear separated. The airplane sustained substantial damage to the right wing. The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.
