## Discrepancy

DURING BASIC CHECK AT EAMS, CORROSION WAS DISCOVERED ON THE P/N 170-12114-001 FLOOR SPLICE IN THE FORWARD WET AREA FLOOR STRUCTURE. REFERENCE ETD2019-170-008053 FIGURE 1 FOR THE DAMAGE LOCATION AND DIMENSIONS. THE DAMAGE LOCATED OVER A FASTENER ROW, AND THEREFORE IT CANNOT BE REPAIRED PER SRM PART II 53-10-10/AD06, WHICH DOES NOT ALLOW DAMAGE ON ANY FASTENER ROW. EAMS REQUESTED AND RECEIVED DISPOSITION FOR A PERMANENT REPAIR IN THE FORM OF ETD2019-170-008053, WHICH ALLOWS THE CORROSION TO BE BLENDED PROVIDED NDT INSPECTION VERIFIES COMPLETE DAMAGE REMOVAL AND SURFACE PROTECTION IS RESTORED. COMPASS ENGINEERING HAS CLASSIFIED THIS AS A MINOR REPAIR. WORK ORDER 2456860183
