Analysis

The flight instructor of the tailwheel equipped airplane reported that, during a 3-point landing, with the student pilot at the flight controls, during the landing roll, the airplane veered left and exited the runway. The flight instructor applied full brakes to no avail. The airplane struck a berm, collapsed the left main landing gear and the left wing was substantially damaged when it impacted the surface. The flight instructor reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.
