Narrative:

We were on an ILS approach to runway 18. The WX was ceiling 500' visibility 5 mi with rain, freezing rain and fog, temperature was 34 degrees dew pt 310, winds 210 at 12 KTS. The ATIS said that the runway was plowed and sanded. The braking action was fair on the runway. We landed on the center of the runway at about 2000' down the runway, a normal landing. I looked down to call out the reverse lights. The right engine came in very quickly, we were in reverse before the left engine came into reverse. When I looked at the N1's, the right engine was at 90 percent, the left engine was at 60 percent and increasing. I called out '90 percent on the right and 75 percent on the left.' I then looked outside and we were drifting to the right. The captain was attempting to control the aircraft. He came out of reverse, but we still were drifting. We believe we hit a small row of snow on the edge of the runway and that helped us move back toward the center of the runway. We had no problem after that. We inspected the aircraft and found no damage. The tower said that there were no runway lights out. I don't know if there would be anything a person could do to prevent this from happening with an icy runway. There was a sligt crosswind and with one engine coming in quicker than the other engine, a person would have to be a little more observant of one engine coming into reverse sooner. If a drift develops, then come out of reverse gain control again then attempt reverse again and hope you can stop.

Title: ACR MLG STARTED TO DRIFT SIDEWAYS ACROSS THE RWY AFTER LNDG. FLT CREW TOOK ACFT OUT OF REVERSE AND DIRECTIONAL CTL WAS REGAINED.

Narrative: WE WERE ON AN ILS APCH TO RWY 18. THE WX WAS CEILING 500' VISIBILITY 5 MI WITH RAIN, FREEZING RAIN AND FOG, TEMP WAS 34 DEGS DEW PT 310, WINDS 210 AT 12 KTS. THE ATIS SAID THAT THE RWY WAS PLOWED AND SANDED. THE BRAKING ACTION WAS FAIR ON THE RWY. WE LANDED ON THE CTR OF THE RWY AT ABOUT 2000' DOWN THE RWY, A NORMAL LNDG. I LOOKED DOWN TO CALL OUT THE REVERSE LIGHTS. THE R ENG CAME IN VERY QUICKLY, WE WERE IN REVERSE BEFORE THE L ENG CAME INTO REVERSE. WHEN I LOOKED AT THE N1'S, THE R ENG WAS AT 90 PERCENT, THE L ENG WAS AT 60 PERCENT AND INCREASING. I CALLED OUT '90 PERCENT ON THE R AND 75 PERCENT ON THE L.' I THEN LOOKED OUTSIDE AND WE WERE DRIFTING TO THE R. THE CAPT WAS ATTEMPTING TO CTL THE ACFT. HE CAME OUT OF REVERSE, BUT WE STILL WERE DRIFTING. WE BELIEVE WE HIT A SMALL ROW OF SNOW ON THE EDGE OF THE RWY AND THAT HELPED US MOVE BACK TOWARD THE CTR OF THE RWY. WE HAD NO PROB AFTER THAT. WE INSPECTED THE ACFT AND FOUND NO DAMAGE. THE TWR SAID THAT THERE WERE NO RWY LIGHTS OUT. I DON'T KNOW IF THERE WOULD BE ANYTHING A PERSON COULD DO TO PREVENT THIS FROM HAPPENING WITH AN ICY RWY. THERE WAS A SLIGT XWIND AND WITH ONE ENG COMING IN QUICKER THAN THE OTHER ENG, A PERSON WOULD HAVE TO BE A LITTLE MORE OBSERVANT OF ONE ENG COMING INTO REVERSE SOONER. IF A DRIFT DEVELOPS, THEN COME OUT OF REVERSE GAIN CTL AGAIN THEN ATTEMPT REVERSE AGAIN AND HOPE YOU CAN STOP.
