## Discrepancy

DURING A ROUTINE INSPECTION, THE RIGHT AILERON BALANCE CABLE (P/N 0510105-362) WAS FOUND CHAFING ON A FAIRLEAD LOCATED MIDWAY THROUGH THE FLAP WELL AREA. THE CABLE IS EXTREMELY DIFFICULT TO EXAMINE THOROUGHLY WHILE INSTALLED. A BORESCOPE CAN AID IN VIEWING THE AREA MORE ACCURATELY. THE BEST METHOD IS TO REMOVE THE CABLE AND PERFORM A BENDING TEST ON THE SHINY AREA, WHICH WILL EXPOSE ANY BROKEN WIRES. THIS OPERATOR HAS A FLEET OF APROXIMATELY 60 AIRCRAFT OF THIS MODEL, AND THIS PROBLEM BEGINS TO MANIFEST ITELF AS EARLY AS 1,500 HOURS TIS.
