## Discrepancy

DURING BASIC CHECK AT EAMS, DENT DAMAGE WAS DISCOVERED ON THE P/N 170-61701-013 REAR FUSELAGE LOWER SKIN AT THREE LOCATIONS IN TWO BAYS BETWEEN FR94/FR95 AND S-21L/S-23L. REFERENCE ETD2020-170-005177-A FIGURE 1 FOR DAMAGE DETAILS. THE DAMAGE IS NOT ALLOWABLE PER SRM PART II 53-30-01/AD02 BECAUSE OF ITS LOCATION, NUMBER AND DISTANCE TO DISCONTINUITIES. EAMS REQUESTED AND RECEIVED A PERMANENT REPAIR IN THE FORM OF ETD2020-170-005177-A, WHICH PROVIDES INSTRUCTIONS TO ACCOMPLISH A DETAILED VISUAL INSPECTION OF THE DENTS TO VERIFY NO SHARP EDGES, CREASES, OIL CANNING, OR DISCREPANT FASTENERS ARE PRESENT AND AN NDT HFEC INSPECTION TO VERIFY NO CRACKS EXIST. DENT A CAN BE REPAIRED BY SRM PART II 53-30-01/AD03 FOR THROUGH DAMAGE, WITH REMAINING DISTORTION ALLOWED TO BE REWORKED. COMPASS ENGINEERING HAS CLASSIFIED THIS AS A MINOR REPAIR. WORK ORDER 2826440
