Compliance: As detailed in the Requirement Document.
Background: The previous issues of this Directive fulfilled the requirements of FAA AD 84-19-02 all Revisions. That was superseded by the initial issue of FAA AD 88-16-03 which in turn was raised to Revision 1 as a result of FAA AD T88-21-50 (AD/B747/67- subsequently cancelled).
Amendment 5 included all of the Requirements from FAA ADs 88-16-03 Rev 1 and T88-21-51. It also increased the number of fail-safe bar fastener holes to be inspected. Amendment 6 referenced Revision 8 of the Requirement document.
Amendment 7 references Revision 9 of the Requirement document and, as there are no longer discrete Australian technical requirements, calls up the technical requirements of the FAA AD in toto.
