Narrative:

After an uneventful flight and landing on main gear wheels; the aircraft veered hard left after nose wheel touchdown at approximately 80 KTS. Aircraft would not correct right with asymmetrical thrust or differential braking. Hard braking was applied; but departing runway to grass was imminent. Chose a path between signage; rolled through grass; engaged nose wheel steering when slow enough to do so and exited grass to taxiway. No damage to aircraft was noted by mechanics and no damage to airport property noted by airport operations. Multiple reports in the past have been made regarding the exact steering anomaly with this type aircraft. I had never experienced the anomaly in many hours in type until now. An ad is issued for the type in direct response to such excursions. This aircraft was in compliance with the ad.
