## Discrepancy

SHIP 9533 - THE CREW DECLARED AN EMERGENCY FOR AN ANTI-SKID FAIL MESSAGE ON FINAL APPROACH. THE QRH WAS COMPLIED WITH, AND ON THE NEXT APPROACH, THE FAILURE MESSAGE DID NOT RETURN. CORRECTIVE ACTION: MAINTENANCE REPLACED THE LEFT LANDING GEAR INTERLOCK RELAY (R2-5052) AND THE ANTI-SKID BRAKE CONTROL UNIT PER B-717 AMM 32-45-00. THE AIRCRAFT WAS RETURNED TO SERVICE.
