THE 315W1702-41 INNER WALL HAS AN 8.25 INCH LONG CRACK THROUGH THE ENTIRE PANEL 12.8 INCHES FROM THE AFT END EXTENDING FORWARD AND CENTERED 5.2 INCHES FROM THE UPPER END OF THE WALL.  THIS REPAIR IS BEING PERFORMED FOR THE MFG, WHO DISCOVERED THE DEFECT WITH THEIR AOG TEAM. WE WERE UNABLE TO DETERMINE THAT THEY HAD REPORTED THE DEFECT UNDER THEIR 145 CERTIFICATE.
