Narrative:

After a normal approach and landing at sat on runway 30L, and after coming to almost a complete stop, I began a very slow and calculated left turn onto taxiway B. Before starting the turn, I looked at the taxiway surface very carefully and observed that the surface appeared to be dry and free of any contamination, including ice, snow, slush and any moisture. During the flight, on the approach and just prior to landing, we were advised that runway braking action had been reported as poor by an air carrier large transport, at approximately xa local. We were anticipating this condition during the landing, but experienced fair to good braking action. With normal braking, actually very little brake pressure and normal reverse, first officer XXX stopped the aircraft in less than 5000' of runway, well before the intersection of 30L and taxiway B. After entering the turn and completely clearing the runway, the nose wheel lost traction and I could not control the aircraft's directional movements. At this time the aircraft began to slide very slowly to the left and traction was never regained. We continued to slide to the left until the aircraft came to rest with the left main landing gear and the nose gear off of the left side of the taxiway. We were moving at the slowest possible speed during this entire incident, so as to avoid this type of situation entirely. The aircraft was very light, only 36 passenger, only 1 in first class, weighing approximately 135000#, 10000# of which was tanker fuel. We found out later that none of the txwys had been salted nor sanded, and no mention was made by the tower nor on the ATIS of any condition of the txwys being unsafe for use. ATIS X was current: xb M8 overcast 3ZF, 23/21 360/11, braking action poor on runway 30L. After this happened the airport was closed due to the WX conditions, not because of our situation. One airport official said that 'I have never seen this type of ice nor have I seen anything this slick.' it was almost impossible to stand, much less walk, on this surface west/O falling, even with shoes with high traction soles. One of our ramp people was standing under the aircraft, west/O moving his feet, and was sliding toward the grass.

Title: DURING EXIT FROM ACTIVE RWY, ACFT SLID OFF OF VERY SLIPPERY TXWY.

Narrative: AFTER A NORMAL APCH AND LNDG AT SAT ON RWY 30L, AND AFTER COMING TO ALMOST A COMPLETE STOP, I BEGAN A VERY SLOW AND CALCULATED LEFT TURN ONTO TXWY B. BEFORE STARTING THE TURN, I LOOKED AT THE TXWY SURFACE VERY CAREFULLY AND OBSERVED THAT THE SURFACE APPEARED TO BE DRY AND FREE OF ANY CONTAMINATION, INCLUDING ICE, SNOW, SLUSH AND ANY MOISTURE. DURING THE FLT, ON THE APCH AND JUST PRIOR TO LNDG, WE WERE ADVISED THAT RWY BRAKING ACTION HAD BEEN RPTED AS POOR BY AN ACR LGT, AT APPROX XA LCL. WE WERE ANTICIPATING THIS CONDITION DURING THE LNDG, BUT EXPERIENCED FAIR TO GOOD BRAKING ACTION. WITH NORMAL BRAKING, ACTUALLY VERY LITTLE BRAKE PRESSURE AND NORMAL REVERSE, F/O XXX STOPPED THE ACFT IN LESS THAN 5000' OF RWY, WELL BEFORE THE INTXN OF 30L AND TXWY B. AFTER ENTERING THE TURN AND COMPLETELY CLEARING THE RWY, THE NOSE WHEEL LOST TRACTION AND I COULD NOT CONTROL THE ACFT'S DIRECTIONAL MOVEMENTS. AT THIS TIME THE ACFT BEGAN TO SLIDE VERY SLOWLY TO THE LEFT AND TRACTION WAS NEVER REGAINED. WE CONTINUED TO SLIDE TO THE LEFT UNTIL THE ACFT CAME TO REST WITH THE LEFT MAIN LNDG GEAR AND THE NOSE GEAR OFF OF THE LEFT SIDE OF THE TXWY. WE WERE MOVING AT THE SLOWEST POSSIBLE SPD DURING THIS ENTIRE INCIDENT, SO AS TO AVOID THIS TYPE OF SITUATION ENTIRELY. THE ACFT WAS VERY LIGHT, ONLY 36 PAX, ONLY 1 IN FIRST CLASS, WEIGHING APPROX 135000#, 10000# OF WHICH WAS TANKER FUEL. WE FOUND OUT LATER THAT NONE OF THE TXWYS HAD BEEN SALTED NOR SANDED, AND NO MENTION WAS MADE BY THE TWR NOR ON THE ATIS OF ANY CONDITION OF THE TXWYS BEING UNSAFE FOR USE. ATIS X WAS CURRENT: XB M8 OVCST 3ZF, 23/21 360/11, BRAKING ACTION POOR ON RWY 30L. AFTER THIS HAPPENED THE ARPT WAS CLOSED DUE TO THE WX CONDITIONS, NOT BECAUSE OF OUR SITUATION. ONE ARPT OFFICIAL SAID THAT 'I HAVE NEVER SEEN THIS TYPE OF ICE NOR HAVE I SEEN ANYTHING THIS SLICK.' IT WAS ALMOST IMPOSSIBLE TO STAND, MUCH LESS WALK, ON THIS SURFACE W/O FALLING, EVEN WITH SHOES WITH HIGH TRACTION SOLES. ONE OF OUR RAMP PEOPLE WAS STANDING UNDER THE ACFT, W/O MOVING HIS FEET, AND WAS SLIDING TOWARD THE GRASS.
