## Discrepancy

CORROSION WAS FOUND AROUND THE WING SCANNING LIGHT CUTOUT AT STA 720B+10 AND S-15L.  THE CORROSION IS WITHIN THE REPAIR LIMITS OF B727 SRM 53-50-5, FIGURE 22 AND WAS BEING REPAIRED BY THAT SECTION.  DURING ACCOMPLISHMENT OF THAT REPAIR SEVEN HOLES WERE DRILLED TOO CLOSE TO THE UPPER SKIN OF THE S-14L LAP JOINT FOR INSTALLATION OF FASTENERS IN THE REPAIR DOUBLER, LITTLE OR NO EDGE MARGIN.
