Narrative:

Flight proceeded to destination airport for approach and landing. Flight executed ILS 30L approach to runway with WX reported 14 overcast 2 1/2 mi visibility light snow, blowing snow, wind variable 350 versus 340, 15 gusting to 22 mph. Temperature 25 degrees. During approach, encountered heavy to moderate rime ice. Runways reported sanded, braking action fair to good. Approach was stabilized to a normal touchdown and landing, braking action good. Stl tower advised flight to turn left on taxiway B, followed by a correction to 'turn right on taxiway B,' gate assigned was occupied. Aircraft was slowed to walking speed. Captain (PF) made a right turn onto taxiway centerline. Both pilots looking straight out of taxiway which appeared normal. As aircraft main landing gear crossed runway edge/crown, aircraft stated a skid towards taxiway edge. Full pedal braking and nose steering ineffective. Captain put both engines into reverse thrust, but found that it did not slow aircraft and felt that it was causing rear of aircraft to skid towards edge of taxiway. Reverse thrust discontinued and aircraft nose skidded to taxiway edge onto grass. Main landing gear remained on hard surface, no damage! Passenger deplaned via 'people mover' to terminal. Clear ice!

Title: TXWY EXCURSION IN A NIGHT OP.

Narrative: FLT PROCEEDED TO DEST ARPT FOR APCH AND LNDG. FLT EXECUTED ILS 30L APCH TO RWY WITH WX RPTED 14 OVCST 2 1/2 MI VISIBILITY LIGHT SNOW, BLOWING SNOW, WIND VARIABLE 350 VERSUS 340, 15 GUSTING TO 22 MPH. TEMP 25 DEGS. DURING APCH, ENCOUNTERED HVY TO MODERATE RIME ICE. RWYS RPTED SANDED, BRAKING ACTION FAIR TO GOOD. APCH WAS STABILIZED TO A NORMAL TOUCHDOWN AND LNDG, BRAKING ACTION GOOD. STL TWR ADVISED FLT TO TURN L ON TXWY B, FOLLOWED BY A CORRECTION TO 'TURN R ON TXWY B,' GATE ASSIGNED WAS OCCUPIED. ACFT WAS SLOWED TO WALKING SPD. CAPT (PF) MADE A R TURN ONTO TXWY CTRLINE. BOTH PLTS LOOKING STRAIGHT OUT OF TXWY WHICH APPEARED NORMAL. AS ACFT MAIN LNDG GEAR CROSSED RWY EDGE/CROWN, ACFT STATED A SKID TOWARDS TXWY EDGE. FULL PEDAL BRAKING AND NOSE STEERING INEFFECTIVE. CAPT PUT BOTH ENGS INTO REVERSE THRUST, BUT FOUND THAT IT DID NOT SLOW ACFT AND FELT THAT IT WAS CAUSING REAR OF ACFT TO SKID TOWARDS EDGE OF TXWY. REVERSE THRUST DISCONTINUED AND ACFT NOSE SKIDDED TO TXWY EDGE ONTO GRASS. MAIN LNDG GEAR REMAINED ON HARD SURFACE, NO DAMAGE! PAX DEPLANED VIA 'PEOPLE MOVER' TO TERMINAL. CLR ICE!
