What was found

(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.
