## Discrepancy

AIRCRAFT WAS GROUNDED: AN EMERGENCY WAS DECLARED ON ARRIVAL AT SEA DUE TO THE FLIGHT CREW REPORTED THAT ENROUTE IN CRUISE THERE WAS A YELLLOW HYDRAULIC SYSTEM LOW PRESSURE AND LOW QUANTITY MESSAGES, AND LOST ALL HYDRAULIC FLUID. THE AIRCRAFT LANDED SAFELY AT SEA AND TOWED TO THE GATE. MAINTENANCE FOUND THE #2 ENGINE DRIVEN HYDRAULIC PUMP LEAKING AND REPLACED IT PER AMM 29-13-51. A SATISFACTORY LEAK / OPERATIONAL CHECK WAS ACCOMPLISHED WITH NO ISSUES NOTED.
