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.
