NO BRAKING ACTION ON LNDG RWY 33. RWY EXCURSION.

Narrative

I WAS FLYING THE APCH AS INDICATED ABOVE. AT 1000 FT ABOVE MINS THE ACFT WAS STABILIZED ON GS AND LOC. BRIEFED APCH SPD WAS 130 KTS. NORMAL FLARE AND TOUCHDOWN. AT THIS POINT; NORMAL REVERSE THRUST AND BRAKING WAS INITIATED. I CONTINUED TO INCREASE PRESSURE ON THE BRAKE PEDALS BUT NO BRAKING ACTION WAS INDICATED. I INFORMED THE CAPT OF THE LACK OF BRAKING EFFECTIVENESS AND HE RETURNED THE REVERSE THRUST LEVERS TO IDLE WHILE I CONTINUED TO APPLY FORWARD CTL WHEEL PRESSURE AND INCREASING THE BRAKE PEDAL PRESSURE. BY THIS TIME THE ACFT HAD INITIATED A SKID TO THE R SIDE OF THE RWY. AS THE SKID DEVELOPED AND PROGRESSED WITH THE ACFT SPD APPROX 100 KTS; THE ACFT DEPARTED THE PREPARED SURFACE APPROX 6000 FT DOWN THE RWY AT A 20-30 DEG ANGLE OFF. SOME CTL EFFECTIVENESS WAS THEN REGAINED USING THE NOSE WHEEL STEERING AND BRAKES. THE ACFT WAS THEN RETURNED TO THE RWY AND BROUGHT TO A CTLED STOP. WE TAXIED CLR AND WERE INSPECTED; PINNED AND TAXIED TO THE RAMP. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO. BRAKING ACTION WAS RPTED FAIR-GOOD BY MU- METER OR JAMES BRAKE DECELEROMETER. TEMP AT THE TIME OF THE INCIDENT 33-34 DEGS. CLAIMS THE ARPT ADVISED GLYCOL HAD BEEN PUT ON THE RWY AT MIDNIGHT. NO SANDING. LIGHT RAIN WAS FALLING AT THE TIME OF THE LNDG IN THE MORNING. TEMP SENSORS WERE BUILT IN THE RWY SO IT IS POSSIBLE TO READ THE RWY TEMP. NO WAY OF RECORDING THIS INFO HOWEVER. SPOILERS HAD DEPLOYED ON LNDG AND THE CAPT TOOK THE ACFT OUT OF REVERSE TO INSURE ONE ENG HAD NOT FAILED TO GO INTO REVERSE. MINOR DAMAGE TO THE ACFT; IT FLEW OUT THE NEXT DAY. FLC WAS GIVEN GND TRAINING AND A CHK RIDE.
