The NTSB's narrative final · quoted from the NTSB record
The pilot reported that the accident landing proceeded normally until he moved the control yoke from full forward to full aft, and the airplane’s tail moved abruptly to the left. The pilot's application of full left rudder and power did not stop the movement, and the airplane entered a ground loop to the right and departed the runway. Examination of the airplane found that the tailwheel spring failed during landing. The observed spring separation was consistent with overload.
