## Discrepancy

DURING BASIC CHECK AT EAMS, CORROSION WAS DISCOVERED TO THE AFT END OF THE CENTER FUSELAGE III RH IB SEAT TRACK BEAM (P/N 170-86082-005) AT FR84 AT THE LAST LUG. REFERENCE ETD2019-170-127266A, FIGURE 1 FOR DAMAGE DETAILS. EAMS REQUESTED AND RECEIVED A REPAIR IN THE FORM OF ETD2019-170-127266A, WHICH PROVIDES INSTRUCTIONS TO TRIM AND BLEND OUT THE CORROSION ON THE END OF THE LEG AND THEN DRILL OUT THE REMAINING DAMAGE TO INSTALL A SOLID RIVET. COMPASS ENGINEERING HAS CLASSIFIED THIS AS A MINOR REPAIR.
