Incident Overview
A private pilot, who had no prior experience in conventional geared aircraft, was receiving his first flight in such an aircraft. The instructor briefed the student before takeoff to avoid using the heel brakes during landing.
Landing Rollout
During the landing rollout, the aircraft's path deviated slightly to the left. In response, the student applied right rudder to correct the divergence. Following this input, the airplane made an abrupt turn to the right. Both the student pilot and the instructor then applied full left rudder in an effort to counteract the right turn. However, they were unable to regain directional control before the airplane completed a ground loop.
Post-Incident Inspection
Following the ground loop, the brake system was inspected. The inspection did not reveal any mechanical malfunctions.
