The NTSB's narrative final · quoted from the NTSB record
The private pilot of the tailwheel-equipped airplane stated that, during the landing roll, the airplane began to veer to the left. The pilot used both brake and rudder inputs in an effort to return to the runway centerline; however, despite the pilot's attempts to regain directional control, the airplane continued off the left side of the runway and ground looped. Postaccident examination of the left landing gear and braking system revealed no evidence of mechanical malfunction or failure that would have precluded normal operation.
