Narrative:

Normal VFR approach, normal touchdown cez runway 21, 1000' down runway, on centerline. Normal calls and procedures. First officer was PF. Shortly after touchdown, first officer placed both power levers to ground idle. Captain called, '2 beta lights, 90 KTS.' at 70 KTS captain called, '70 KTS, I've got the airplane.' first officer responds, 'your airplane, slick runway.' aircraft continued to track straight on runway centerline. Just prior to reaching 40 KTS, aircraft begins to drift slightly right of centerline. First officer called, '40 KTS.' at 40 KTS aircraft began sharper turn to the right. Aircraft confign--full flaps, speeds high, nose wheel steering off. Captain applied full reverse, full left rudder and full brakes to no avail. Aircraft exited right side of runway at approximately 30 KTS. Engines developing full reverse, right engine experienced a ground strike (24' snowbank). Captain shut off both engines using manual stop/feather knob and continued to secure the aircraft. First officer opened main cabin door, checked the condition of the passenger (5 total) and assisted them out and away from the aircraft. There were no injuries sustained by either of the crew of any of the passenger. Contributing factors--snow packed runway, narrow runway, nose wheel steering was not armed, night operation, nose wheel steering had a hard over 250 hours prior. Human performance considerations: intentional initial drift to right of runway, nose wheel steering not armed, fatigue (sixth leg, 5.1 hours, last leg of day), company procedure of transferring aircraft to captain at 70 KTS (perhaps difficult for captain to regain feel of aircraft), lack of experience in operating aircraft west/O nose wheel steering when NWS is normally used and general (operating large aircraft), crews were leery of another hard over despite NWS being replaced and clrd by maintenance, and technique--only left engine reverse and left brake should have been used to control right yawing movement.

Title: ACR SMT LNDG ON SLICK RWY DRIFTED OFF SIDE AND DAMAGED RIGHT PROPELLER.

Narrative: NORMAL VFR APCH, NORMAL TOUCHDOWN CEZ RWY 21, 1000' DOWN RWY, ON CENTERLINE. NORMAL CALLS AND PROCS. F/O WAS PF. SHORTLY AFTER TOUCHDOWN, F/O PLACED BOTH PWR LEVERS TO GND IDLE. CAPT CALLED, '2 BETA LIGHTS, 90 KTS.' AT 70 KTS CAPT CALLED, '70 KTS, I'VE GOT THE AIRPLANE.' F/O RESPONDS, 'YOUR AIRPLANE, SLICK RWY.' ACFT CONTINUED TO TRACK STRAIGHT ON RWY CENTERLINE. JUST PRIOR TO REACHING 40 KTS, ACFT BEGINS TO DRIFT SLIGHTLY RIGHT OF CENTERLINE. F/O CALLED, '40 KTS.' AT 40 KTS ACFT BEGAN SHARPER TURN TO THE RIGHT. ACFT CONFIGN--FULL FLAPS, SPDS HIGH, NOSE WHEEL STEERING OFF. CAPT APPLIED FULL REVERSE, FULL LEFT RUDDER AND FULL BRAKES TO NO AVAIL. ACFT EXITED RIGHT SIDE OF RWY AT APPROX 30 KTS. ENGS DEVELOPING FULL REVERSE, RIGHT ENG EXPERIENCED A GND STRIKE (24' SNOWBANK). CAPT SHUT OFF BOTH ENGS USING MANUAL STOP/FEATHER KNOB AND CONTINUED TO SECURE THE ACFT. F/O OPENED MAIN CABIN DOOR, CHKED THE CONDITION OF THE PAX (5 TOTAL) AND ASSISTED THEM OUT AND AWAY FROM THE ACFT. THERE WERE NO INJURIES SUSTAINED BY EITHER OF THE CREW OF ANY OF THE PAX. CONTRIBUTING FACTORS--SNOW PACKED RWY, NARROW RWY, NOSE WHEEL STEERING WAS NOT ARMED, NIGHT OPERATION, NOSE WHEEL STEERING HAD A HARD OVER 250 HRS PRIOR. HUMAN PERFORMANCE CONSIDERATIONS: INTENTIONAL INITIAL DRIFT TO RIGHT OF RWY, NOSE WHEEL STEERING NOT ARMED, FATIGUE (SIXTH LEG, 5.1 HRS, LAST LEG OF DAY), COMPANY PROC OF TRANSFERRING ACFT TO CAPT AT 70 KTS (PERHAPS DIFFICULT FOR CAPT TO REGAIN FEEL OF ACFT), LACK OF EXPERIENCE IN OPERATING ACFT W/O NOSE WHEEL STEERING WHEN NWS IS NORMALLY USED AND GENERAL (OPERATING LARGE ACFT), CREWS WERE LEERY OF ANOTHER HARD OVER DESPITE NWS BEING REPLACED AND CLRD BY MAINT, AND TECHNIQUE--ONLY LEFT ENG REVERSE AND LEFT BRAKE SHOULD HAVE BEEN USED TO CTL RIGHT YAWING MOVEMENT.
