Background: Reports have been received of contact between the No.14 fuel spray nozzle fuel supply tube and the L/H C-duct forward hold open rod.

This amendment, although having no affect on the requirement of the original issue of this Directive, introduces terminating action of the initial and repetitive inspection requirements of this Directive.
