Narrative:

When I arrived at the gate for departure I called flight control and asked to make sure the runway 28 was plowed and sanded. This was after I read the field report. Flight control dispatcher called me back at the aircraft and verified it was done. During final approach WX XE20 overcast 2 south wind 130 at 12, braking 30 (fair), I told the first officer to check tailwind chart and it indicated a 9 KT tailwind. I was flying the aircraft and chose to use 50 degree flap. I landed on runway 28 just prior to the fifth runway light from threshold in the center, braking was ok at T/D, however as I approached intersection 18/36 braking became nil. The aircraft slid 90 degrees to the runway and came to a stop. The main gear was 10' outside of the light. Nose gear on the runway. At this time I did not know I was off the runway. I started to taxi to the gate and noticed a runway light missing. Maintenance inspected aircraft. No damage. After the landing I walked onto the runway and found the surface to have solid ice, covered by 1/2' wet snow. The first officer also went out with me the second time to confirm T/D marks and runway condition! What I believe caused the problem and what can be done to prevent a recurrence or correct the situation: the validity of the method of testing the braking information of the runway is subjective. How often is the brake meter tested for reliability, is the sanding equipment tested for dispensing the proper amount? What type of tires are on the truck with the brake meter?

Title: ACR MLG RWY EXCURSION AT TVC.

Narrative: WHEN I ARRIVED AT THE GATE FOR DEP I CALLED FLT CTL AND ASKED TO MAKE SURE THE RWY 28 WAS PLOWED AND SANDED. THIS WAS AFTER I READ THE FIELD RPT. FLT CTL DISPATCHER CALLED ME BACK AT THE ACFT AND VERIFIED IT WAS DONE. DURING FINAL APCH WX XE20 OVCST 2 S WIND 130 AT 12, BRAKING 30 (FAIR), I TOLD THE F/O TO CHK TAILWIND CHART AND IT INDICATED A 9 KT TAILWIND. I WAS FLYING THE ACFT AND CHOSE TO USE 50 DEG FLAP. I LANDED ON RWY 28 JUST PRIOR TO THE FIFTH RWY LIGHT FROM THRESHOLD IN THE CENTER, BRAKING WAS OK AT T/D, HOWEVER AS I APCHED INTXN 18/36 BRAKING BECAME NIL. THE ACFT SLID 90 DEGS TO THE RWY AND CAME TO A STOP. THE MAIN GEAR WAS 10' OUTSIDE OF THE LIGHT. NOSE GEAR ON THE RWY. AT THIS TIME I DID NOT KNOW I WAS OFF THE RWY. I STARTED TO TAXI TO THE GATE AND NOTICED A RWY LIGHT MISSING. MAINT INSPECTED ACFT. NO DAMAGE. AFTER THE LNDG I WALKED ONTO THE RWY AND FOUND THE SURFACE TO HAVE SOLID ICE, COVERED BY 1/2' WET SNOW. THE F/O ALSO WENT OUT WITH ME THE SECOND TIME TO CONFIRM T/D MARKS AND RWY CONDITION! WHAT I BELIEVE CAUSED THE PROB AND WHAT CAN BE DONE TO PREVENT A RECURRENCE OR CORRECT THE SITUATION: THE VALIDITY OF THE METHOD OF TESTING THE BRAKING INFO OF THE RWY IS SUBJECTIVE. HOW OFTEN IS THE BRAKE METER TESTED FOR RELIABILITY, IS THE SANDING EQUIP TESTED FOR DISPENSING THE PROPER AMOUNT? WHAT TYPE OF TIRES ARE ON THE TRUCK WITH THE BRAKE METER?
