## Discrepancy

AIRCRAFT WAS GROUNDED: AN EMERGENCY WAS DECLARED INTO DFW DUE TO THE FLIGHT CREW REPORTING AT 31000 THEY HAD FLAP LOCK FLASHING UNTIL THE FLAPS WERE MOVED TO FLAPS 2. THEY ALSO REPORTED RECIEVING A WING TIP LOCKED ECAM. THE FLIGHT CREW ACCOMPLISHED A GO AROUND AND ACCOMPLISHED THE ECAM PROCEDURES. AT FLAPS 3 THE INDICATION CLEARED ITSELF. THE AIRCRAFT LANDED SAFELY AT DFW WITHOUT FURTHER INCIDENT. MAINTENANCE FOUND THE BLUE AND GREEN HYDRAULIC SYSTEMS WERE LOW AND THE YELLOW SYTEM WAS OVERSERVICED. MAINTENANCE SERVICED ALL 3 HYDRAULIC SYSTEMS PER AMM 12-12-29. A SATISFACTORY OPERATIONAL CHECK OF THE SLATS / FLAP SSYTEMS WAS ACCOMPLISHED WITH NO ISSUES NOTED.
