## Discrepancy

SHIP 9529 - THE "ANTI-SKID FAIL" MESSAGE ILLUMINATED WHILE ON FINAL APPROACH. THE CREW DECLARED AN EMERGENCY WITH ATC AND LANDED NORMALLY. CORRECTIVE ACTION: MAINTENANCE REPLACED THE ANTI-SKID BRAKE CONTROL UNIT, BOTH INBOARD ANTI-SKID DUAL BRAKE CONTROL VALVES, AND BOTH LANDING GEAR INTERLOCK RELAYS. GEAR EXTENSION AND RETRACTION FUNCTIONAL TEST PASSED. THE AIRCRAFT HAS RETURNED TO SERVICE. (LP #8475286)
