## Discrepancy

THE HYDRAULIC SYSTEM 3 ELEVATOR OFF LIGHT CAME ON JUST PRIOR TO LANDING AT LGW.  THE ELEVATOR FEEL CHANNEL LIGHT CAME ON AFTER LANDING.  THE AIRCRAFT HAD LOST FLUID FROM THE NR 3 HYDRAULIC SYSTEM.  MAINTENANCE FOUND THE NR 3 ENGINE DRIVEN RIGHT HYDRAULIC PUMP HOUSING LEAKING.  THE HYDRAULIC PUMP WAS REMOVED AND REPLACED.  THE NR 3 HYDRAULIC SYSTEM WAS SERVICED.  LEAK AND OPERATIONAL CHECKS WERE GOOD.
