Analysis 

The pilot reported that, during landing, the tailwheel-equipped airplane had a "small bounce" and then veered to the right. He added that he attempted to correct, and the "tail came around quick in a clockwise ground loop." Subsequently, the airplane exited the right side of the runway onto soft terrain, the left main landing gear collapsed, and the left wing struck the ground.

The airplane sustained substantial damage to the left wing.

The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.
