What happened
A private pilot was conducting his first flight in a conventional geared aircraft. Prior to takeoff, the instructor advised the student to avoid using the heel brakes during the landing phase.
During the landing rollout, the aircraft began a slight turn to the left. In an attempt to correct this divergence, the student applied right rudder. This action caused the airplane to make an abrupt turn to the right. Both the student and the instructor applied full left rudder in an effort to counteract the rightward turn; however, they were unable to regain directional control before the aircraft ground looped.
The investigation
An inspection of the brake system was conducted following the incident. The investigation found no mechanical malfunctions within the braking system.
