    Applicability: All Models except T6.

                 Requirement: 1. Visually inspect both Waggler attach arms for cracks in accordance with Edge Aviation Service Bulletin EA-AT-2000/001 Issue 1 Section 2. Anticipated crack locations are as indicated at Figure 1.

                 2. Modify in accordance with Edge Aviation Service Bulletin EA-AT-2000/001 Issue 1 Section 3 or a modification approved by a CAR 35 Authorised Person.

                   Note: Wagglers modified in accordance with the initial issue of this AD have waggler arms which have been doubled in thickness by the addition of welded doublers to the outer faces of the side attachment arms. Total thickness of the side attachment arms of modified wagglers should be approximately 0.098" (2.49mm). Wagglers so modified meet requirement 2 of this AD.
 COMMONWEALTH OF AUSTRALIA (Civil Aviation Regulations 1998), PART 39 - 105 CIVIL AVIATION SAFETY AUTHORITY
 SCHEDULE OF AIRWORTHINESS DIRECTIVES

             Compliance: 1. Unless already accomplished, before further flight and thereafter at intervals not exceeding 100 hours time in service until modified.

             2. Unless already accomplished, within 12 months from the date of effect of this amendment.

            This Amendment becomes effective on 29 September 2000.

            Background: The original issue of this AD was raised as a result of two instances of control column waggler arm cracking having been found following aileron control malfunction. This amendment is issued as a result of a further case of a seriously cracked waggler, and also to update the AD and require modification of the wagglers rather than indefinite periodic inspections.

 William Ronald Smith
 Delegate of the Civil Aviation Safety Authority 26 September 2000

 The above AD is notified in the Commonwealth of Australia Gazette on 29 September 2000.
