## Discrepancy

DURING A ROUTINE INSPECTION, HYDRAULIC FLUID WAS FOUND IN THE WHEEL WELLS.  THE LEAK WAS TRACED TO A CRACK IN A RIGHT HAND BRAKE LINE, PN 1159H20014.  THE CRACK STARTED IN A SLIGHT GROOVE THAT MAY HAVE BEEN A MANUFACTURER'S TOOLING MARK THAT WAS INFLICTED WHEN THE TUBING WAS MANUFACTURED OR BENT TO FORM THE ASSEMBLY.  THE LINE HAS BEEN INSTALLED FOR 30 YEARS.
