## Discrepancy

DURING THE B2 BASIC CHECK AT EAMS, CORROSION WAS FOUND ON THE AFT WET AREA RH FLOOR BEAM (P/N 170-65669-004) AT FR87. THE CORROSION DAMAGE CAN BE REPAIRED BY SRM PART II 53-23-10 REPAIR 02 BY REMOVING THE DAMAGE AND INSTALLING A REPAIR DOUBLER. BECAUSE THE FLOOR TRACK IS A PSE, ACCOMPLISHMENT OF THIS EO HAS BEEN CLASSIFIED AS A MAJOR REPAIR DUE TO STRENGTH RESTORATION. SUPPLEMENTAL FOLLOW-ON INSPECTIONS OF THIS NEW REPAIR ARE NOT REQUIRED PER SRM PART II 53-23-10 REPAIR 02. EO E175-53MR-478 IS BEING ACCOMPLISHED UNDER WO 2813290.
