 COMMONWEALTH OF AUSTRALIA (Civil Aviation Regulations 1998), PART 39 - 107 CIVIL AVIATION SAFETY AUTHORITY
 SCHEDULE OF AIRWORTHINESS DIRECTIVES

             Compliance: 1. Upon accumulation of 600 hours component time in service and thereafter at intervals not to exceed 600 hours component time in service.

             2.    Before 30 November 1994, unless one of the Service Bulletins listed at Note 2. has previously been accomplished.

           3.    At each seat installation or re-installation after 30 December 1999. This Amendment becomes effective on 30 December 1999.
           Background: Reports were received of cases of the seat aft track fitting unlocking from the floor track. The DGAC requires replacement of the current aft track fitting with an improved track fitting with a positive locking system.

           Amendment 1 was issued to reflect the revised DGAC AD which introduces the replacement of tab locks and provides an alternate compliance with SB 90-25-009 and became effective on 10 November 1994.

           Amendment 2 is issued to permit only one use of the P/N 00-4399 locking tabs.

           The original issue of this Airworthiness Directive became effective on 23 June
