## Discrepancy

(CAN) DURING CLIMBOUT WHILE PERFORMING AFTER TAKEOFF CHECKS THE FLIGHT CREW REPORTED THE ANTI-SKID INOPERATIVE LIGHT BEGAN TO FLICKER AND THEN STAYED ILLUMINATED.  DUE TO OPERATIONAL LIMITATIONS ASSOCIATED WITH AN INOPERATIVE ANTI-SKID SYSTEM IT WAS DECIDED THAT THE ACFT WOULD RETURN TO ITS DEPARTING STATION.  AN UNEVENTFUL LANDING WAS MADE AND THE ACFT WAS MET BY MAINTENANCE.  MAINTENANCE CARRIED OUT THE FOLLOWING FIM TASKS AND RECTIFICATION, FIM 32-42, TASK 801.  C/O AND AACU SHOWS VALVE 4.  RESISTANCE OF NR 4 ANTI-SKID VALVE WELL OUT OF LIMITS.  NR 4 ANTI-SKID VALVE REPLACED + TESTS SERVICEABLE IAW AMM 32-42-31.  ACFT RETURNED TO SERVICE.
