## Discrepancy

THE LOWER SILL BEAM OF THE C2 DOOR OPENING WAS BADLY CORRODED AND REQUIRED REPLACEMENT.  TO REMOVE AND INSTALL A NEW SECTION, THE OUTER CHORD OF THE FS 1440 OPENING FRAME WAS CUT AT STRINGER 26R AND THE WEB CUT AT STRINGER 23R.  THE LOWER SECTIONS WERE REMOVED AND RE-INSTALLED AFTER THE SILL REPLACEMENT.  THE WEB WAS SPLICED PER SRM AND THE CHORD WITH ALUMINUM ANGLES PER ER/A 381623-14, REV A.
