## Discrepancy

AIRCRAFT WAS GROUNDED: AN EMERGENCY WAS DECLARED INTO DFW DUE TO THE FLIGHT CREW REPORTING A GREEN HYDRAULIC RESERVOIR LOW LEVEL ECAM INFLIGHT. THE FLIGHT CREW PERFORMED A MANUAL GRAVITY EXTENSION OF THE LANDING GEAR AND LANDED SAFELY AT DFW WHERE THE AIRCRAFT WAS TOWED TO THE GATE.  MAINTENANCE FOUND THE FLEXIBLE HYDRAULIC HOSE FOR THE ENGINE DRIVEN PUMP PRESSURE SWITCH FOR THE GREEN HYDRULIC SYSTEM ON THE NR 1 ENGINE LEAKING AND REPLACED IT PER AMM 29-11-49. A SATISFACTORY LEAK & OPS CHKD WAS ACCOMPLISHED WITH NO ISSUES NOTED.
