## Discrepancy

THE BL 0.07 FLOORBEAM UPPER CAP OF THE WING CENTER SECTION IS CRACKED ALL THE WAY THROUGH THE CAP JUST FORWARD OF FS 664 AT A NUTPLATE HOLE.  NO CRACKS WERE FOUND IN THE WEB.  THE CRACK IS TYPICAL PER BOEING SERVICE BULLETIN 737-57-1210.  THE ER/A WILL INSTALL THE SERVICE BULLETIN REPAIR FOR THIS CONDITION.
