## Discrepancy

THE STA 1183 BULKHEAD WEB WAS FOUND CRACKED IN TWO LOCATIONS.  THE DAMAGE WAS TRIMMED OUT WITH DIMENSIONS OF 2.6250 INCH AT LBL 8, WL 190 AND 8 INCH BY 3.1250 INCH AT LBL 14, WL 173.  THE BULKHEAD WEB IS MANUFACTURED FROM 0.050 INCH CLAD 2024-T3.  THIS ER/A AUTHORIZES INSTALLATION OF A REPAIR DOUBLER.
