Analysis
The flight instructor reported that while demonstrating touch and go landings, he completed a normal touchdown. On rollout, the airplane began to veer to the right. The pilot attempted to correct with full left rudder and brake; however, the airplane exited the right side of the runway and bounced up a small dirt embankment. The airplane completed a full rotation and the left wing impacted terrain, which resulted insubstantial damage to the left aileron. The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.
