## Discrepancy

(CAN) AFTER TAKEOFF, INBD ANTISKID CAUTION LIGHT ILLUMINATED ON THE CAUTION AND WARNING PANEL (CAWP). UPON ARRIVAL, FLIGHT CREW REPORTED THAT THE NUMBER 3 MAIN WHEEL WAS NOT ROTATING. THE MAINTENANCE CREW DISPATCHED TO THE AIRCRAFT FOUND THE NUMBER 3 TIRE COMPLETELY DEFLATED AND NOTICED PRESENCE OF A FLAT SPOT. DURING REPLACEMENT OF THE MAIN WHEEL ASSEMBLY, IT WAS NOTED THAT THE WHEEL INNER BEARING HAD FAILED CAUSING SIGNIFICANT DAMAGES TO THE BRAKE ASSEMBLY, WHEEL INNER AND OUTER HALVES. THE AXLE WAS ALSO FOUND BENT. THE AXLE, BOTH MAIN WHEEL AND BRAKE ASSEMBLIES WERE REPLACED AND THE ANTI-SKID SYSTEM TESTED SERVICEABLE BEFORE RETURNING THE AIRCRAFT INTO SERVICE.
