Narrative:

Approach profile was an ILS to 4R circle to 13C. Landing was a flaps 40. Runway condition was reported good. Touchdown, braking and reverse thrust was normal. Txwys were reported poor to nil so I made a momentary stop on 13C, initiated a slow left turn onto taxiway K. During the initial turn with the landing lights on, I could see the surface changed from dull to shiny and wet. As the nose tire entered the taxiway, I tested the brakes and nosewheel steering was responding normally. As soon as the main tires entered the taxiway, I again tested the braking action and immediately noted and commented to the first officer that the braking action was nil. At the same time the aircraft appeared to be caught by a gust of wind and began sliding laterally to the left. I attempted nosewheel steering, differential braking and reverse thrust. There was no effect on directional control. The aircraft came to a stop after the left main gear entered the mud. Because of ramp conditions, I stopped prior to entering the taxiway. Upon landing, mdw tower simply stated to contact ground control after clearing the runway. No preferred taxi route was given. Initial responding vehicles all had problems controling their cars and trucks. Conversations with various company personnel stated they had been trying to get the airport to sand the ramp/txwys starting at XX00 CST. Conversation with midway airport (runway sanding supervisor) stated he was not sure why some primary txwys had not been treated and additionally voiced his concern over the type of chemicals and sand being used. From practical experience and conversation with company and midway airport personnel, it appears that there is no real plan to handle ice on txwys and ramps. It appears the airport needs to establish a primary taxi-in/taxi-out route for each runway and then mdw tower/ATIS could announce the canned route. Supplemental information from acn 230235: too many times a pilot will not call a surface nil on the radio (the radio is recorded) because he doesn't want to be the bad guy.

Title: MLG SLIDES OFF THE TXWY AFTER CLRING THE LNDG RWY.

Narrative: APCH PROFILE WAS AN ILS TO 4R CIRCLE TO 13C. LNDG WAS A FLAPS 40. RWY CONDITION WAS RPTED GOOD. TOUCHDOWN, BRAKING AND REVERSE THRUST WAS NORMAL. TXWYS WERE RPTED POOR TO NIL SO I MADE A MOMENTARY STOP ON 13C, INITIATED A SLOW L TURN ONTO TXWY K. DURING THE INITIAL TURN WITH THE LNDG LIGHTS ON, I COULD SEE THE SURFACE CHANGED FROM DULL TO SHINY AND WET. AS THE NOSE TIRE ENTERED THE TXWY, I TESTED THE BRAKES AND NOSEWHEEL STEERING WAS RESPONDING NORMALLY. AS SOON AS THE MAIN TIRES ENTERED THE TXWY, I AGAIN TESTED THE BRAKING ACTION AND IMMEDIATELY NOTED AND COMMENTED TO THE FO THAT THE BRAKING ACTION WAS NIL. AT THE SAME TIME THE ACFT APPEARED TO BE CAUGHT BY A GUST OF WIND AND BEGAN SLIDING LATERALLY TO THE L. I ATTEMPTED NOSEWHEEL STEERING, DIFFERENTIAL BRAKING AND REVERSE THRUST. THERE WAS NO EFFECT ON DIRECTIONAL CTL. THE ACFT CAME TO A STOP AFTER THE L MAIN GEAR ENTERED THE MUD. BECAUSE OF RAMP CONDITIONS, I STOPPED PRIOR TO ENTERING THE TXWY. UPON LNDG, MDW TWR SIMPLY STATED TO CONTACT GND CTL AFTER CLRING THE RWY. NO PREFERRED TAXI RTE WAS GIVEN. INITIAL RESPONDING VEHICLES ALL HAD PROBS CTLING THEIR CARS AND TRUCKS. CONVERSATIONS WITH VARIOUS COMPANY PERSONNEL STATED THEY HAD BEEN TRYING TO GET THE ARPT TO SAND THE RAMP/TXWYS STARTING AT XX00 CST. CONVERSATION WITH MIDWAY ARPT (RWY SANDING SUPVR) STATED HE WAS NOT SURE WHY SOME PRIMARY TXWYS HAD NOT BEEN TREATED AND ADDITIONALLY VOICED HIS CONCERN OVER THE TYPE OF CHEMICALS AND SAND BEING USED. FROM PRACTICAL EXPERIENCE AND CONVERSATION WITH COMPANY AND MIDWAY ARPT PERSONNEL, IT APPEARS THAT THERE IS NO REAL PLAN TO HANDLE ICE ON TXWYS AND RAMPS. IT APPEARS THE ARPT NEEDS TO ESTABLISH A PRIMARY TAXI-IN/TAXI-OUT RTE FOR EACH RWY AND THEN MDW TWR/ATIS COULD ANNOUNCE THE CANNED RTE. SUPPLEMENTAL INFO FROM ACN 230235: TOO MANY TIMES A PLT WILL NOT CALL A SURFACE NIL ON THE RADIO (THE RADIO IS RECORDED) BECAUSE HE DOESN'T WANT TO BE THE BAD GUY.
