Analysis
The student pilot reported that during a touch-and-go practice landing and takeoff, he landed the airplane and applied power to take off. As the airplane accelerated, it began to veer to the left. Despite the student pilot's control inputs, the airplane continued to veer to the left, exited the runway surface, struck a ditch, and nosed over, which resulted in substantial damage to the vertical stabilizer and rudder. The student pilot reported no preimpact mechanical malfunctions or failures with the airplane that would have precluded normal operation.
