## Discrepancy

THE FLIGHT CREW REPORTED THAT DURING FLIGHT AT FLIGHT LEVEL 320 THE EMERGENCY PRESSURIZATION AND AMC BLEED LEAK MESSAGE ILLUMINATED. THE FLIGHT CREW RAN THE CHECKLIST AND ELECTED TO DIVERT THE FLIGHT AND LAND FOR MAINTENANCE CONSIDERATIONS. THE MAINTENANCE TEAM TROUBLESHOT AND DETERMINED THE AMC BLEED DETECTOR UNIT WAS DEFECTIVE. THE UNIT WAS REPLACED WITH A NEW UNIT, OPS CHECKS WERE SATISFACTORY, AND THE AIRCRAFT WAS RETURNED TO SERVICE.
