DURING 763CK'S C4 CHECK AT OSC KALITTA, CORROSION WAS FOUND ON THE STA 1153 FRAME ASSEMBLY INNER CHORD (P/N 146T1060-2) IN THE LOWER CARGO COMPARTMENT. THE CHORD HAD TO BE REPLACED DUE TO THE EXTENT OF CORROSION. UPON REMOVAL OF THE CHORD, AN UNDOCUMENTED TRIM OUT OF THE FRAME WEB (P/N 146T1204-3) WAS FOUND AT RBL 6.5. IT WAS DETERMINED THAT THE FRAME WEB COULD NOT BE REPAIRED PER ANY OF THE REPAIRS GIVEN IN THE B767 SRM, SO FLIGHT VEHICLES CONSULTING, INC., WAS CONTACTED TO PROVIDE AN FAA-DER APPROVED REPAIR. THE PURPOSE OF THIS REA IS TO AUTHORIZE AND DOCUMENT ACCOMPLISHMENT OF REF /A/, WHICH IS AN FAA-DER APPROVED REPAIR.ANALYSIS:THE FRAME WEB IS CONSIDERED FCS STRUCTURE PER SRM 51-00-04, 767-FCBS-53-008, NOTE 1.
