## Discrepancy

FRAME 6 FLOOR BEAM HAS HEAVY MILLED GUSSETS THAT TIE THE FRAME 6 FLOOR BEAM TO THE FRAME 6 SIDE WALL, BOTH FWD AND AFT OF THE BEAM, ON THE LH AND RH SIDES OF THE BEAM.  THERE ARE NUT PLATES CLOSE TO THE ENDS OF THE GUSSETS, AND CORROSION WAS FOUND IN THE GUSSETS WHERE THE NUT PLATE ATTACHED.  THE RH SIDE GUSSETS WERE WITHIN OEM ACCEPTABLE LIMITS, BUT THE LH SIDE GUSSETS HAD CORROSION BEYOND THE OEM LIMITS.  THE OEM ENGINEERED A REPAIR SCHEME FOR THE CORRODED LOCATIONS, WHICH WAS ACCOMPLISHED.
