Analysis
The student pilot in the tailwheel equipped airplane reported that, during the takeoff ground roll he did not apply enough right rudder input to compensate for the propellers asymmetric blade effect. The airplane veered off the left side of the runway and ground looped. The right wing and horizontal stabilizer were substantially damaged. The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.
