## Discrepancy

THIS EO IS BEING ISSUED TO PROVIDE INSTRUCTIONS TO ACCOMPLISH A PERMANENT REPAIR OF CORROSION DAMAGE TO THE UPPER FLANGE OF THE CENTER FUSELAGE III RT BEAM P/N 170-65669-004 AT FR87. THE DAMAGE MEASURES APPROXIMATELY 2 INCHES X 1 INCH X 0.022 INCH DEEP. THE PERMANENT REPAIR WILL BE ACCOMPLISHED BY DOUBLER INSTALLATION PER SRM PART II 53-23-10/REPAIR 01P, FIGURE 203. THE BEAM IS A PSE, THEREFORE ACCOMPLISHMENT OF THIS EO HAS BEEN CLASSIFIED AS A MAJOR REPAIR DUE TO STRENGTH RESTORATION. THIS IS NOT CLASSIFIED AS FCS AND DOES NOT REQUIRE SUPPLEMENTAL FOLLOW UP INSPECTIONS.
