## Discrepancy

AIRCRAFT WAS GROUNDED: AN EMERGENCY WAS DECLARED AND THE AIRCRAFT RETURNED TO DFW DUE TO THE FLIGHT CREW REPORTING A YELLOW HYDRAULIC PUMP OVERHEAT MESSAGE JUST AFTER FLAP RETRACTION. FLIGHT CREW ACCOMPLISHED THE ECAM PROCEDURES AND THE AIRCRAFT LANDED SAFELY AT DFW WITHOUT FURTHER INCIDENT. MAINTENANCE REPLACED THE YELLOW HYDRAULIC SYSTEM ELECTRIC PUMP 3075GX AND ACCOMPLISHED A SATISFACTORY LEAK / OPERATIONAL CHECK PER AMM 29-24-51.
