## Discrepancy

AIRCRAFT WAS GROUNDED: AN EMERGENCY WAS DECLARED UPON ARRIVAL INTO DFW DUE TO GREEN HYDRAULIC SYSTEM LOW PRESSURE AND GREEN HYDRAULIC SYSTEM ENGINE PUMP PRESSURE LOW ECAM MESSAGES. THE AIRCRAFT LANDED SAFELY AT DFW AND TAXIED TO THE GATE UNDER ITS OWN POWER. MAINTENANCE FOUND THE #2 ENGINE HYDRAULIC PUMP LEAKING FROM THE PUMP BODY AND REPLACED IT PER AMM 29-11-51. A SATISFACTORY LEAK / OPERATIONAL CHECK WAS ACCOMPLISHED.
