The pilot of a tailwheel-equipped airplane reported that during landing the airplane bounced, subsequently the leaf spring on the tail wheel broke midspan. The pilot further reported that the airplane veered to the right despite full left rudder deflection and brake application, which resulted in a ground loop, left main landing gear collapse, and substantial damage to the left wing.

The pilot reported there were no preimpact mechanical failures or malfunctions with the airframe or engine that would have precluded normal operation.
