Narrative:

Our flight was uneventful until touchdown. The weather was good and the aircraft touched down normally on centerline; with zero drift and in the touchdown zone. When brakes were evenly applied the aircraft slewed immediately and drastically to the left. I countered with full right brake and rudder and initiated nose wheel steering. The left main and nose wheel departed the runway. As the aircraft slowed the nose wheel steering became more effective which allowed me to steer the aircraft back on the runway. Postflight inspection revealed minor damage.
