## Discrepancy

AIRCRAFT WAS GROUNDED: AN EMERGENCY WAS DECLARED INTO SJU DUE TO THE FLIGHT CREW REPORTING A GREEN HYDRAULIC SYSTEM RESERVOIR LOW LEVEL ECAM WARNING. THE FLIGHT CREW ACCOMPLISHED THE ECAM PROCEDURES WHICH PROMPTED THEM TO TURN OFF THE PTU AND THE #1 ENGINE HYDRAULIC PUMP WHICH RESULTED IN THE LOSS OF THE GREEN HYDRAULIC SYSTEM. THE AIRCRAFT LANDED SAFELY AT SJU AND TAXIED TO THE GATE UNDER ITS OWN POWER.    MAINTENANCE FOUND #1 ENGINE, ENGINE DRIVEN PUMP PRESSURE LINE CRACKED AT WORN RUBBER CLAMPS AND REPLACED IT PER AMM 29-11-49. A SATISFACTORY LEAK / OPERATIONAL CHECK WAS ACCOMPLISHED.
