               Applicability: 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.

                  Requirement: 1. Inspect the left wing aft wing break electrical connector in accordance with ASTA Nomad SB ANMD-57-13 Revision 1.

2.        If any contamination is found during the Requirement 1 inspection clean the connector in accordance with ASTA Nomad SB ANMD-57-13 Revision 1.

3.        If any arcing damage, deposits between contacts or looseness of contacts is found during the Requirement 1 inspection incorporate either Modification N875 (N22 aeroplanes) or Modification N876 (N24 aeroplanes) in accordance with ASTA Nomad SB ANMD-57-13 Revision 1.

               Incorporation of Modification N875 or N876 is considered terminating action for the Requirement 1 repetitive inspections.

               Compliance: For Requirement 1 - Within 300 hours time in service (TIS) from the last inspection accomplished in accordance with the original issue of AD/GAF-N22/74 and thereafter at intervals not to exceed 300 hours TIS until Modification N875 or N876 is incorporated.

               For Requirement 2 - Before further flight following the Requirement 1 inspection. For Requirement 3 - Before further flight following the Requirement 1 inspection. This Amendment becomes effective on 1 November 2001.
               Background:  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.
