## Discrepancy

DURING SCHEDULED INSPECTION NOTED HYDRAULIC FLUID LEAK FROM HYDRAULIC LINE CONNECTING POWER BRAKE SYSTEM FILTER ASSY.  TO SYSTEM ACCUMULATOR.  FURTHER INVESTIGATION REVEALED TUBING TO BE CRACKED NEXT TO B NUT FITTING.  POSSIBLE CAUSES MAY INCLUDE TUBING MISALIGNMENT OR OVERTORQUING OF B-NUT AT SOME POINT, RESULTING IN FATIGUE CRACKING.  TECH NEEDS TO FOLLOW PROCEDURES IN MM WHEN REINSTALLING TUBING AND HOSE CONNECTIONS.
