## Discrepancy

DURING A WING NDT INSPECTION OF THE UPPER RT WING PLANK AT FS 452 AND BL 33, CORROSION WAS NOTED IN THIS AREA.  ENGINEERING HAS DETERMINED THIS CORROSION IS EXCESSIVE ENOUGH TO REQUIRE ACCOMPLISHMENT OF ASC 229, WHICH REMOVES THE CORROSION ON THE PLANK AND INSTALLS A DOUBLER PLATE AND A NEW STYLE WING ATTACH PIN AS A CORRECTIVE ACTION.
