What was found
WE HAD A REPEAT OCCOURANCE OF THE BRAKE SYSTEM NOT WORKING PROPERLY. THE CREW LANDED AND THE BRAKES WORKED AS INTENDED BUT AFTER STOPPING THE BRAKES STOPPED WORKING (HYDRAULIC PUMP TURNED OFF THAT SUPPLIES PRESSURE TO THE BRAKES). THE CREW USED THE BACKUP BRAKE SYSTEM AND BROUGHT THE AIRCRAFT TO A STOP AND SIGNALED GROUND CREW TO CHOCK THE AIRCRAFT AND HOOK UP A TUG TO GET IT TO THE PARKING AREA. WE SENT A TEAM FROM SBP TO PSP WHERE THE AIRCRAFT WAS LOCATED AND IDENTIFIED A FAULTY RELAY IN THE BRAKE SYSTEM THAT TURNED THE HYDRAULIC MOTOR ON/OFF. WE BELIEVE THIS WILL BE THE FINAL FIX FOR THIS INTERMITTENT ISSUE.
