Narrative:

We were instructed to taxi to runway 22 via taxiway 'J.' 3 snow removal trucks were in the process of sweeping 'J' as we approached it from the ramp area. We made a right turn onto 'J' from the ramp. As I attempted to straighten the aircraft I immediately noticed the aircraft sliding to the right. I tried to arrest the slide with nosewheel steering, differential braking and reverse thrust. All had no effect. The taxiway was a clean sheet of ice. The slide was very slow and we came to a stop on the side of the taxiway with the right main gear touching the grass. There was no sand or urea applied to the taxiway after it was brushed. Braking action was nil. The runway was crowned much more than others. There was a 25-30 KT crosswind at the time (left to right). After brushing the txwys, they should be sanded and a car should check braking action before aircraft are allowed on the affected area.

Title: ACR ALMOST SLIDES OFF ICY TXWY.

Narrative: WE WERE INSTRUCTED TO TAXI TO RWY 22 VIA TXWY 'J.' 3 SNOW REMOVAL TRUCKS WERE IN THE PROCESS OF SWEEPING 'J' AS WE APCHED IT FROM THE RAMP AREA. WE MADE A R TURN ONTO 'J' FROM THE RAMP. AS I ATTEMPTED TO STRAIGHTEN THE ACFT I IMMEDIATELY NOTICED THE ACFT SLIDING TO THE R. I TRIED TO ARREST THE SLIDE WITH NOSEWHEEL STEERING, DIFFERENTIAL BRAKING AND REVERSE THRUST. ALL HAD NO EFFECT. THE TXWY WAS A CLEAN SHEET OF ICE. THE SLIDE WAS VERY SLOW AND WE CAME TO A STOP ON THE SIDE OF THE TXWY WITH THE R MAIN GEAR TOUCHING THE GRASS. THERE WAS NO SAND OR UREA APPLIED TO THE TXWY AFTER IT WAS BRUSHED. BRAKING ACTION WAS NIL. THE RWY WAS CROWNED MUCH MORE THAN OTHERS. THERE WAS A 25-30 KT XWIND AT THE TIME (L TO R). AFTER BRUSHING THE TXWYS, THEY SHOULD BE SANDED AND A CAR SHOULD CHK BRAKING ACTION BEFORE ACFT ARE ALLOWED ON THE AFFECTED AREA.
