## Discrepancy

DURING THE HEAVY CHECK OF THE AIRCRAFT, DAMAGE WAS DISCOVERED ON THE LT IB SEAT TRACK (P/N 170-03264-001) AT THE FR19 CROSSBEAM IN THE FORWARD CABIN FLOOR STRUCTURE. THE BEAM WILL BE REPAIRED BY CUTOUT AND DOUBLER INSTALLATION PER SRM PART II 53-10-10 REPAIR 01P. THE LT SEAT TRACK BEAM IS NOT CLASSIFIED AS FATIGUE CRITICAL STRUCTURE (FCS), BUT IT IS CLASSIFIED AS PRIMARY STRUCTURE. ACCOMPLISHMENT OF THIS EO HAS BEEN CLASSIFIED AS A MAJOR REPAIR DUE TO STRENGTH RESTORATION OF PRIMARY STRUCTURE. SUPPLEMENTAL FOLLOW UP INSPECTIONS ARE NOT REQUIRED PER SRM PART II 53-10-10 REPAIR 01P.
