## Discrepancy

AIRCRAFT WAS GROUNDED: AN EMERGENCY WAS DECLARED INBOUND INTO DFW DUE TO THE FLIGHT CREW REPORTING THAT ABOUT 50 MINUTES FROM DFW A HYDRAULIC GREEN RESERVOIR LOW LEVEL MESSAGE DISPLAYED. THE FLIGHT CREW REPORTED THAT THE PRESSURE REMAINED AT 3000 PSI WITH PUMP OFF AND PTU FAULT. THE AIRCRAFT LANDED SAFELY AT DFW AND TAXIED TO THE GATE UNDER ITS OWN POWER. MAINTENANCE FOUND THAT THE HYDRAULIC PUMP OUTLET HOSE O-RING CUT AND THE HYDRUALIC LINE WAS LOOSE. MAINTENANCE REPLACED THE O-RING AND SECURED THE LINE PER AMM 29-11-51. A SATISFACTORY LEAK /OPERATIONAL CHECK WAS ACCOMPLISHED WITH NO ISSUES NOTED.
