## Discrepancy

MQY - A 3 INCH CRACK WAS FOUND DURING INSPECTION OF THE RUDDER QUADRANT STRUCTURE P/N 137390C415.  THE CRACK WAS IN THE EDGE MEMBER P/N 137390C120 WHICH SECURES THE SKINS AND BULKHEADS TOGETHER.  THE CRACK IS CAUSED BY THE P/N 137370E6 D-WASHER (PACKER) WHICH IS CHAFING AGAINST THE RADIUS OF THE EDGE MEMBER P/N 137390C120.  THE D-WASHER IS USED TO ASSIST IN ATTACHING THE RUDDER ARTIFICAL FEEL BUNGEES.  THE EDGE MEMBER WAS REPLACED AND THE D-WASHER WAS RE-WORKED TO ENSURE A CORRECT FIT IN RELATION TO THE EDGE MEMBER RADIUS.  THE AIRCRAFT RETURNED TO SERVICE.  PART TC:  16,556.(X)
