Narrative:
This was third landing of the day. Other two normal, no abnormalities noted on preflts or post flts. Normal and stable approach, mains normal touchdown. Upon nosewheel touchdown, aircraft experienced significant, uncommanded right turn. Applied left rudder and brake, continued to the right, so applied full left rudder, left brake and used tiller. Aircraft right main and nose gear departed paved surface and struck 3 runway edge lights. As aircraft slowed, we were able to get back on the runway. Taxied to ramp and aircraft continued to veer to the right. Possible cause was steering activator not centered or low on pressure which may have caused it to turn slightly on touchdown.
