Incident Overview
A pilot reported that after touching down on Runway 03, he applied the brakes to stop the aircraft. Immediately after brake application, the aircraft began a hard left turn. The pilot applied full right rudder, aileron, and right brake but was unable to arrest the turn. He then applied full power to the engine in an attempt to stop the turn, but with no success.
Departure from Runway
The airplane veered off the left side of the runway, down a slight incline, across a shallow ditch, and came to rest in a grassy area just west of the parallel taxiway.
Post-Incident Inspection
Inspection of the aircraft revealed that both the right and left tires were fully inflated, and the left and right brakes rotated freely.
