## Discrepancy

SHIP 9523 -HYD/DE- THE CREW RECEIVED A "HYD R QTY LOW" MESSAGE AT TOP OF CLIMB. THEY WERE UNABLE TO REPRESSURIZE THE SYSTEM. THE QRH WAS COMPLIED WITH AND PERFORMED THE ALTERNATE GEAR EXTENSION (DUE TO A RIGHT HYDRAULIC SYSTEM LOW QUANTITY). AN EMERGENCY WAS DECLARED WITH ATC AND THE LANDING WAS UNEVENTFUL. CORRECTIVE ACTION: MAINTENANCE REPLACED THE ELECTRIC AUXILIARY HYDRAULIC PUMP AND THE RIGHT MAIN LANDING GEAR DOOR (DUE TO RUNWAY CONTACT ON LANDING). THE SHIP HAS RETURNED TO SERVICE. (LP #4580142)
