ACR MLG RWY EXCURSION TAXIING INTO POSITION FOR TKOF DUE TO ICE AND SNOW ON RWY.

Narrative

WHILE TAXIING SLOWLY ONTO RWY 36 AT CVG; A SHALLOW RIGHT TURN WAS ATTEMPTED IN ORDER TO ALIGN THE ACFT ON THE CENTERLINE FOR TKOF. THE NOSE WHEEL STEERING WAS INEFFECTIVE IN TURNING TO ALIGN THE ACFT. BRAKING AND REVERSE THRUST WERE USED TO ATTEMPT TO ARREST THE FORWARD PROGRESS OF THE ACFT W/O EFFECT. THE ACFT SLID VERY SLOWLY OFF THE LEFT SIDE OF THE RWY WITH THE LEFT MAIN GEAR AND NOSE GEAR RESTING JUST OFF THE LEFT SIDE OF THE RWY AND THE RIGHT MAIN GEAR ON THE RWY. THE TXWY AND RUNUP AREA WERE A COMBINATION OF PITTED ICE AND GRAINY SNOW. WHILE WAITING FOR AN ATC RELEASE TIME; A 90 DEG TURN WAS MADE IN THE RUNUP PAD WITH NO PARTICULAR PROB. BUT; WHEN TAXIING ONTO THE RWY; A GLAZE ICE SURFACE WAS ENCOUNTERED WHICH DIDN'T ALLOW TURNING; BRAKING OR ARRESTING THE PROGRESS OF THE ACFT. NEITHER THE RUNUP PAD NOR THE RWY HAD BEEN SANDED OR TREATED IN ANY WAY TO REDUCE THE EFFECT OF THE ICE AND SNOW. THE TWR WAS REPORTING RWY 36 BRAKING AS 'FAIR TO GOOD;' WHEN IN FACT IT WAS NIL IN THE TKOF AREA. THE CONDITION OF THE TKOF AREA OF RWY 36 SHOULD HAVE BEEN CHKED AND EITHER SANDED OR NOT USED AS BRAKING AND MANEUVERING ON THIS SURFACE WAS IMPOSSIBLE. THE TWR AND COMPANY OPS WERE NOTIFIED IMMEDIATELY. THE PAX DEPLANED DOWN THE REAR STAIRS WITH NO FURTHER INCIDENT. THE EXCURSION WAS SO GENTLE THAT THE F/A'S AND MOST PAX WEREN'T AWARE THAN ANYTHING IRREGULAR HAD OCCURRED. THERE WAS NO DAMAGE TO THE ACFT AND IT WAS BACK IN SVC WITHIN AN HR. SUPPLEMENTAL INFORMATION FROM ACN 81608: BRAKING ACTION HAD BEEN RPTED AS 'FAIR TO GOOD' IN THE TOUCHDOWN AND ROLLOUT ZONES; HOWEVER; THE FIRST 200-300' WERE GLARE; UNSANDED ICE. THE RWY SURFACE CONDITION IN THAT AREA WAS FAR WORSE THAN THE TXWY. NO RWY LIGHTS WERE STRUCK AND THE ACFT WAS NOT DAMAGED.
