Analysis

The flight instructor reported that he and the pilot receiving instruction were practicing takeoffs and landings in a tailwheel-equipped airplane. During takeoff, the pilot receiving instruction applied excessive right rudder and the airplane went to the right, he relieved the right rudder, and the airplane veered to the left, traveling diagonally across the runway. The flight instructor applied aft pressure on the stick to get the airplane airborne, simultaneously the pilot receiving instruction reduced the throttle to idle. The airplane bounced and impacted terrain and nosed over. The airplane sustained substantial damage to the fuselage, empennage and wings. The pilot reported no pre-impact mechanical malfunctions or failures with the airplane that would have precluded normal operation.
