## Discrepancy

THE OUTER CAP OF THE LOWER SILL BEAM OF THE C1 DOOR OPENING WAS FOUND WITH SEVERAL AREAS OF CORROSION.  TO REMOVE THE OUTER STRUCTURE, THE OUTER STRUCTURE AND WEB OF THE FS 620 FRAME WERE CUT AND THE LOWER SECTIONS REMOVED.  A NEW SILL STRUCTURE WAS THEN INSTALLED AND THE LOWER SECTIONS OF FRAME CHORD AND WEB SPLICED BACK IN PLACE WITH ALUMINUM REPAIR DOUBLERS PER ER/A 384501-14, REV A.
