Narrative:

Flight was flown as scheduled from ewr-ymx. It was flown entirely at night and was normal through touchdown and landing rollout. On approach, ATIS called for runway 24 with 160 ft in the center as bare with some ice on the edges. Winds were 230 degrees 09 KTS with good ceiling and visibility. All txwys had 'rough ice' with some at 100%. There was no mention of glare ice or unusable txwys. On rollout, braking action was good and the aircraft was slowed to a crawl prior to turning on taxiway B4. Shortly after entering taxiway B4 the aircraft started to drift to the right. The captain used nosewheel steering, differential braking and reverse thrust to control the aircraft and keep it on the taxiway. When the aircraft stopped the left main and nose gear were on the pavement but the right main gear was off the taxiway. Speed throughout the maneuver was 1-2 KTS maximum. Mirabel ramp and ATC (tower/ground) were notified and efforts to extract the aircraft were initiated. Airport and air carrier ramp personnel cleared the snow from around the right gear and sanded taxiway B4. After the captain inspected the gear and its position off the taxiway and consulted with mirabel maintenance and maintenance at home base, it was decided to try and power the aircraft back on the taxiway. This effort was successful. The aircraft was again checked for damage and none was found. The aircraft was taxied to the ramp and was towed in due to ice on the ramp. No damage to aircraft or to airfield facilities was noted.

Title: AN ACR DC10 FREIGHTER FLC SLID OFF OF A TXWY THAT WAS COVERED WITH ICE AND SNOW. THE ACFT WAS INSPECTED BY MAINT PERSONNEL THEN SUCCESSFULLY TAXIED BACK ONTO THE TXWY. NO ACFT DAMAGE.

Narrative: FLT WAS FLOWN AS SCHEDULED FROM EWR-YMX. IT WAS FLOWN ENTIRELY AT NIGHT AND WAS NORMAL THROUGH TOUCHDOWN AND LNDG ROLLOUT. ON APCH, ATIS CALLED FOR RWY 24 WITH 160 FT IN THE CTR AS BARE WITH SOME ICE ON THE EDGES. WINDS WERE 230 DEGS 09 KTS WITH GOOD CEILING AND VISIBILITY. ALL TXWYS HAD 'ROUGH ICE' WITH SOME AT 100%. THERE WAS NO MENTION OF GLARE ICE OR UNUSABLE TXWYS. ON ROLLOUT, BRAKING ACTION WAS GOOD AND THE ACFT WAS SLOWED TO A CRAWL PRIOR TO TURNING ON TXWY B4. SHORTLY AFTER ENTERING TXWY B4 THE ACFT STARTED TO DRIFT TO THE R. THE CAPT USED NOSEWHEEL STEERING, DIFFERENTIAL BRAKING AND REVERSE THRUST TO CTL THE ACFT AND KEEP IT ON THE TXWY. WHEN THE ACFT STOPPED THE L MAIN AND NOSE GEAR WERE ON THE PAVEMENT BUT THE R MAIN GEAR WAS OFF THE TXWY. SPD THROUGHOUT THE MANEUVER WAS 1-2 KTS MAX. MIRABEL RAMP AND ATC (TWR/GND) WERE NOTIFIED AND EFFORTS TO EXTRACT THE ACFT WERE INITIATED. ARPT AND ACR RAMP PERSONNEL CLRED THE SNOW FROM AROUND THE R GEAR AND SANDED TXWY B4. AFTER THE CAPT INSPECTED THE GEAR AND ITS POS OFF THE TXWY AND CONSULTED WITH MIRABEL MAINT AND MAINT AT HOME BASE, IT WAS DECIDED TO TRY AND PWR THE ACFT BACK ON THE TXWY. THIS EFFORT WAS SUCCESSFUL. THE ACFT WAS AGAIN CHKED FOR DAMAGE AND NONE WAS FOUND. THE ACFT WAS TAXIED TO THE RAMP AND WAS TOWED IN DUE TO ICE ON THE RAMP. NO DAMAGE TO ACFT OR TO AIRFIELD FACILITIES WAS NOTED.
