## Discrepancy

DURING A SCHEDULED MAINTENANCE VISIT WHILE PERFORMING A (C) LEVEL INSPECTION A BRAKE RETURN LINE WAS FOUND TO BE CHAFING FROM A SCREW THAT SECURES THE CENTER COCKPIT TO CABIN FLOORBOARD.  INSPECTION AND REPAIR OF THIS AREA IS OUTLINED IN SB 53-3511.  THE CHAFED PORTION OF THE BRAKE LINE (P/N 128-580101-1) WAS CUT OUT AND A NEW SECTION OF BRAKE LINE WAS  INSTALLED USING A D10036-06 UNION..  THE BRAKE SYSTEM WAS BLED AND LEAK CHECKS WERE GOOD.  THE SCREW HOLE THAT ALLOWED THE CHAFING WAS RELOCATED.  ALL WORK WAS COMPLETED IAW SB 53-3511 AND THE MM.
