## Discrepancy

LANDED UNDER AMBER ALERT DUE TO LOSS OF A SYSTEM HYDRAULICS.  RIGID HYDRAULIC TUBE P/N 65C26809-1100 FAILED, ALLOWING THE A SYSTEM HYDRAULIC FLUID TO BLEED OUT.  SUBSEQUENT INSPECTION FOUND THAT THE LINE HAD SHEARED ADJACENT TO WHERE IT WAS SECURED TO STRUCTURE WITH A CLAMP.  THE HYDRAULIC LINE RUNS BETWEEN THE WING SPAR AND THE A SYSTEM EDP.  THE HYDRAULIC LINE WAS REPLACED, NEW MOUNTING BRACKETS AND CLAMPS WERE INSTALLED, THE HYDRAULIC SYSTEM WAS SERVICED.
