accomplished in accordance with SB 2/47 Revision D.

                1.a. Repeat the inspection within 2 years of the last inspection, and thereafter at intervals not to exceed 2 years.

                2. Within 12 months after the effective date of this Directive.
             This Amendment becomes effective on 5 July 2007.
Background:  Cracks have been discovered in the tailplane front centre spar web and gusset plate of an Australian aircraft.

             Amendment 1, effective 6 March 1992, corrected an oversight in the Compliance and introduced a reference to Transport Canada AD CF-91-42.

             Amendment 2 updated the revision status of the requirement document, with no change to the compliance.

             Amendment 3 is issued in response to a revision of the related Transport Canada AD, which was prompted by reports of cracks in the front spar centre web of the tailplane at the pick-up bracket and at lightening holes.  The TC AD revision was issued to reflect the new requirements to inspect the tailplane front spar web behind the pick-up brackets using fluorescent penetrant inspection, instead of the visual inspection method used previously.

             The original issue of this AD became effective on 30 April 1992.
