## Discrepancy

AIRCRAFT WAS GROUNDED: AN EMERGENCY WAS DECLARED AND THE AIRCRAFT DIVERTED TO PHX DUE TO THE FLIGHT CREW REPORTING A YELLOW HYDRAULIC SYSTEM LOW LEVEL MESSAGE. THE AIRCRAFT LANDED SAFELY AT PHX AND WAS TOWED TO THE GATE. MAINTENANCE FOUND THE HYDRAULIC ELBOW FITTING LEAKING IN THE #2 PYLON AND REPLACED IT PER EO 2922E003-004. A SATISFACTORY LEAK / OPERATIONAL CHECK WAS ACCOMPLISHED.
