Aircraft veered right after landing; pilot and instructor unable to regain control despite brake application. Post-accident examination found brakes operational.

Incident Overview

During a routine flight, the pilot and instructor reported an uneventful flight with all systems functioning normally. The approach and landing were conducted under calm wind conditions. After touchdown, the pilot retracted the flaps, pushed the carburetor heat to cold, and opened the cowl flaps. At that moment, the aircraft began to veer to the right.

Loss of Directional Control

As the turn became more pronounced, the pilot applied additional brake pressure, but without effect. The pilot then called for assistance from the instructor, who was also unable to regain directional control. The aircraft continued to veer off the runway.

Post-Incident Examination

Following the incident, an FAA inspector conducted a visual and functional examination of the aircraft. The inspection determined that the brakes were operational.
