## Discrepancy

LFEC INSPECTION OF THE STRINGER 4L SKIN LAP SPLICE BETWEEN FS 360 AND 460 INDICATED A SINGLE CRACK.  INTERNAL HFEC INSPECTION CONFIRMED ONE CRACK ONLY AT FS 444.  THE CRACK WAS ROUTED OUT OF THE SKIN LAP AND REPAIRED PER THE B727 SRM 53-30-3, FIG 5.  TEN FASTENERS FWD AND AFT OF THE CRACK WERE ADDITIONALLY REMOVED TO ALLOW FOR HFEC SURFACE SCAN WITH NO RIVET TAIL INTERFERENCE.  NO OTHER CRACKS WERE NOTED.
