## Discrepancy

DURING C-CHECK INSPECTION, A CRACK WAS FOUND AT THE 0 BBL FUSELAGE FRAME AT BS 663.  THE CRACK EXTENDS THROUGH THE UPPER CHORD AND THROUGH THE WEB.  THE REPAIRS HAVE BEEN ACCOMPLISHED ON NON ROUTINE 031284, USING SB KIT 65C34537-1. RELATED TO THIS REPAIR IS A SUSPECTED PRESSURIZATION LEAK NOTED AT BS 663.75 ON NON ROUTINE 031167.  THE REPAIR OF THE 0 BBL WILL ENSURE THAT THE PRESSURIZATION LEAK IS REPAIRED AS IT IS IN THE SAME AREA.  (M)
