GAF N22 and N24 Series Aeroplanes AD/GAF-N22/69 Amdt 6 Ailerons 11/2009

Applicability: All Model N22 and N24 Series aircraft. Requirement: 1. Action in accordance with ASTA Nomad Alert Service Bulletin ANMD-57-18 Issue 1 dated 14 August 2006.

2. Incorporate ASTA Nomad Alert Service Bulletin ANMD-27-53 dated 20 February 2008.

Incorporation of ANMD-27-53 dated 20 February 2008 cancels the limitations imposed by Alert Service Bulletin ANMD-57-18, and is terminating action for this Airworthiness Directive. Compliance: Requirement 1: Within 50 hours time in service after 26 October 2006 or before 26 November 2006, whichever occurs first.

Requirement 2: Before 30 June 2010.

The compliance time for Requirement 1 remains unchanged from the previous Amendment of this Airworthiness Directive. This Amendment becomes effective on 22 October 2009. Background: Late in 2002 the manufacturer advised CASA of another Nomad accident which was possibly caused by aileron flutter with the flaps at 38 degrees. This, along with the other flutter incidents, has resulted in the manufacturer issuing ANMD-57-18 Issue 1 as a precautionary measure while they further investigate the issue.
