 COMMONWEALTH OF AUSTRALIA (Civil Aviation Regulations 1998), PART 39 - 105 CIVIL AVIATION SAFETY AUTHORITY
 SCHEDULE OF AIRWORTHINESS DIRECTIVES

 Compliance: As detailed in the Requirement table.

            This Amendment becomes effective on 13 July 2000.

            Background:  The initial issue of this directive was raised to promulgate the wing and carry-thru structure fatigue life limitations, which were based on the results of a comprehensive program of full scale fatigue tests conducted by the manufacturer. Subsequent amendments updated the lives as the test program continued; and consolidated the content with that of other directives. There are some differences between some of the lives shown above and the corresponding lives shown in SB 744 and the FAA AD, however all Australian lives derive directly from the fatigue test program.
