## Discrepancy

THE SKIN JUST FWD OF THE BUTT SPLICE AT STA 80 WAS FOUND TO BE CORRODED AND WAS CUT OUT.  THE RESULTING CUT OUT MEASURES 4.25 X 3.  THIS CUT OUT IS 3 AWAY FROM AN EXISTING EXTERNAL REPAIR AT S-28R WHICH REPAIRS A 5 X 1 CUT OUT.  BOTH REPAIRS WILL BE INCLUDED IN THE NEW REPAIR.  MTC IS ACCOMPLISHING THE REPAIR IN B727 SRM 53-30-3 FIG 3A WITHOUT DEVIATION EXCEPT TO TIE IN BOTH REPAIRS.  DUE TO CORROSION UNDERNEATH THE EXISTING REPAIR, S-28R WILL BE REPAIRED WITH AN SRM STRINGER SPLICE.
