## Discrepancy

(CAN) DURING INSPECTION, A SMALL RUSTY LINE WAS NOTED ON THE RUDDER MOUNT ASSY. WHICH AFTER FURTHER INSPECTION WAS REVEALED AS A CRACK ALONG THE TOP OF THE WELD AS SHOWN.  A NEW MOUNT ASSY WAS INSTALLED.  THE PART HAS SEEN SOME IMPROVEMENTS IN THE LAST FEW YEARS WHICH HAS SEEN THE PN GO FROM A -03 TO A -05 AND NOW A -07.  THE LABEL ON THE UNIT IS DIFFICULT TO READ, BUT OUR RECORDS DO NOT SHOW REPLACEMENT OF THE UNIT, I HAD TO ASSUME IT WAS A -05 OR EARLIER PART.  SO FAR I HAVE NOT SEEN A FAILURE OF THE -07.
