Flight Crew Human Performance
Dispatched to oma with anti-skid inoperative. LLWS in effect at oma. Normal flight to oma. On final tower reports winds at 170 degrees at 24 KTS gusting to 34 KTS. Normal touchdown. At approximately 80 KTS, the aircraft began to slide to the left. Tried to maintain directional control with rudder and aileron, but aircraft continued to WX vane to the right. At some point, light brakes were applied, but he right brake grabbed, so brakes were released. We exited the runway at taxiway C and tower reported heavy smoke coming from the right brake. Wee stopped on taxiway C, and I requested that emergency equipment be sent. Once stopped, the tower reported that the smoke had ceased. I informed flight attendants and passenger of our condition, and that we would proceed to the gate shortly. Talked to fire rescue and advised that no smoke or fire visible, and that all tires were inflated. Requested clearance to taxi to the gate with emergency equipment to follow. Once at the gate, inspection revealed flat spots on all 4 main tires. Talk to both dispatch and maintenance crew. 2 mechanics and 4 new tires sent to replace the worn tires. Aircraft was signed off and ferried back for maintenance.
