Narrative:

We landed normally on runway 19, went into full reverse and applied brakes. Aircraft did not want to decelerate normally. We ended up about 200' onto paved overrun. Upon post-flight inspection we discovered 1 of 4 right main gear tires was still inflated but unserviceable. All 4 brakes on right gear were cold. Other 3 tires were in great shape. Left gear tires were all in great shape and brakes were hot (a normal condition). Apparently the right gear hydroplaned, rendering that side's antiskid inoperative, resulting in greatly reduced braking effectiveness. We would have chosen longer runway but it was closed. Our charts indicated runway 19 would be more than adequate. Lights at threshold were embedded type. No damage to aircraft or lights.

Title: ACR HVT UNABLE TO STOP ON RWY. SLID ONTO OVERRUN.

Narrative: WE LANDED NORMALLY ON RWY 19, WENT INTO FULL REVERSE AND APPLIED BRAKES. ACFT DID NOT WANT TO DECELERATE NORMALLY. WE ENDED UP ABOUT 200' ONTO PAVED OVERRUN. UPON POST-FLT INSPECTION WE DISCOVERED 1 OF 4 RIGHT MAIN GEAR TIRES WAS STILL INFLATED BUT UNSERVICEABLE. ALL 4 BRAKES ON RIGHT GEAR WERE COLD. OTHER 3 TIRES WERE IN GREAT SHAPE. LEFT GEAR TIRES WERE ALL IN GREAT SHAPE AND BRAKES WERE HOT (A NORMAL CONDITION). APPARENTLY THE RIGHT GEAR HYDROPLANED, RENDERING THAT SIDE'S ANTISKID INOP, RESULTING IN GREATLY REDUCED BRAKING EFFECTIVENESS. WE WOULD HAVE CHOSEN LONGER RWY BUT IT WAS CLOSED. OUR CHARTS INDICATED RWY 19 WOULD BE MORE THAN ADEQUATE. LIGHTS AT THRESHOLD WERE EMBEDDED TYPE. NO DAMAGE TO ACFT OR LIGHTS.
