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

            Note 2: AD/B737/81 Amdt 1 mandated compliance with Boeing Service Bulletin 737- 78-1053R1, R2 or R3 by 31 December, 1999.

            Note 3: FAA AD 94-21-05 R1 Amdt 39-9314 refers and revises 94-21-05 Amdt 39-
            9047.

            This Amendment becomes effective on 13 July 2000.

            Background: The original Directive was issued to introduce a periodic functional test of the thrust reverser sync-lock system. The sync-lock system was introduced as part of an on- going design review of thrust reverser systems following an accident that was attributed to an uncommanded in-flight deployment of a thrust reverser.

            Amendment 1 issued in November 95 raised to reflect a minor editorial revision to the original FAA AD and make reference to an approved alternate test.

            Amendment 2 was issued to clarify and include FAA approved changes to the FAA Sync-Lock Integrity Test Procedures and Reference latest FAA AD and Boeing message dated 19 December 1994.

            Amendment 1 of this Airworthiness Directive became effective on 9 November 1995.

            The original issue of this Airworthiness Directive became effective on 2 February 1995.
