Narrative:

Upon nosewheel touchdown, we received a steering inoperative message on EICAS with a corresponding yaw to the right. Left rudder and brake were added to compensate for the yaw. The aircraft remained close to centerline at all times. The captain assumed control at approximately 70 KTS, slowing the aircraft on the runway. The checklist was used to try to reset the nosewheel steering system with no result. The checklist then called for use of differential braking and thrust to taxi the aircraft. While trying to make a right 90 degree turn to exit the runway, the nosewheel fully deflected to the right. This left us with little choice but to shut down and ask for a tow. The aircraft never exited a runway or the taxiway but the airport was closed down for approximately 45 mins. Simulator experience in taxiing aircraft without nosewheel steering may be helpful.

Title: CL65 ACFT EXPERIENCED NOSEWHEEL STEERING FAILURE AFTER TOUCHDOWN. AFTER ATTEMPTING TO EXIT RWY THE ACFT WAS TOWED TO GATE. ARPT CLOSED FOR 45 MINS AS A RESULT.

Narrative: UPON NOSEWHEEL TOUCHDOWN, WE RECEIVED A STEERING INOP MESSAGE ON EICAS WITH A CORRESPONDING YAW TO THE R. L RUDDER AND BRAKE WERE ADDED TO COMPENSATE FOR THE YAW. THE ACFT REMAINED CLOSE TO CTRLINE AT ALL TIMES. THE CAPT ASSUMED CTL AT APPROX 70 KTS, SLOWING THE ACFT ON THE RWY. THE CHKLIST WAS USED TO TRY TO RESET THE NOSEWHEEL STEERING SYS WITH NO RESULT. THE CHKLIST THEN CALLED FOR USE OF DIFFERENTIAL BRAKING AND THRUST TO TAXI THE ACFT. WHILE TRYING TO MAKE A R 90 DEG TURN TO EXIT THE RWY, THE NOSEWHEEL FULLY DEFLECTED TO THE R. THIS LEFT US WITH LITTLE CHOICE BUT TO SHUT DOWN AND ASK FOR A TOW. THE ACFT NEVER EXITED A RWY OR THE TXWY BUT THE ARPT WAS CLOSED DOWN FOR APPROX 45 MINS. SIMULATOR EXPERIENCE IN TAXIING ACFT WITHOUT NOSEWHEEL STEERING MAY BE HELPFUL.
