The AD requires that the action set out in the requirement section (being action that the delegate considers necessary to correct the unsafe condition) be taken in relation to the aircraft or aeronautical product mentioned in the applicability section: (a) in the circumstances mentioned in the requirement section; and (b) in accordance with the instructions set out in the requirement section; and (c) at the time mentioned in the compliance section.\n\n![](image.003.png)AD/GAF-N22/74\n\nAmdt 1\n\n  \n\nLeft Wing Aft Wing Break Electrical Connector\n\n  \n11/2001\n\nApplicability: Nomad N22 and N24 series aeroplanes, line sequence numbers as listed in Aerospace Technologies of Australia (ASTA) Nomad Service Bulletin (SB) ANMD-57-13 Revision 1 dated 14 August 2001.\n\nRequirement: 1. Inspect the left wing aft wing break electrical connector in accordance with ASTA Nomad SB ANMD-57-13 Revision 1.\n\n    2.

For Requirement 3 \\- Before further flight following the Requirement 1 inspection. This Amendment becomes effective on 1 November 2001.\n\nBackground: The original issue of this directive advised that ASTA had received reports of uncommanded flap extensions and incorrect stall warning indications. ASTA determined that contamination in the left aft wing electrical connector might have caused these occurrences. The actions specified in the Directive were designed to reduce the likelihood of the occurrences.\n\nCOMMONWEALTH OF AUSTRALIA (Civil Aviation Regulations 1998), PART 39 \\- 105 CIVIL AVIATION SAFETY AUTHORITY\n\nSCHEDULE OF AIRWORTHINESS DIRECTIVES\n\n![](image.004.png)This amendment introduces optional modifications (modification kits are available free of charge from ASTA) that eliminate the requirement for repetitive inspections.
