## Discrepancy

SHIP 9505 -HYD/DE- THE FLIGHT CREW DECLARED AN EMERGENCY WITH ATC DUE TO THE RIGHT HYDRAULIC QUANTITY READING LOW. THE CREW WAS ABLE TO PRESSURIZE THE R HYD SYSTEM BETWEEN 5,000-10,000 PSI PER THE QRH. DURING THIS TIME WHEN THE R HYD LIGHT WENT OUT AND PRESS WAS NORMAL, THE CREW LOWERED THE LANDING GEAR NORMALLY. THEN THE R HYD LIGHT ILLUMINATED AGAIN, PRESSURE REMAINED AT 3000 PSI. THE LANDING WAS UNEVENTFUL. CORRECTIVE ACTION: MAINTENANCE FOUND AN AFT HYDRAULIC LINE ON INBOARD FILTER HOUSING LEAKING AND REPLACED AN O-RING. LEAK AND OPERATIONAL CHECKS WERE GOOD. (LP #4642322)
