 SCHEDULE OF AIRWORTHINESS DIRECTIVES

 Pilatus Porter PC-6 Series Aeroplanes

AD/PC-6/38 Horizontal Stabiliser Inspection 7/93

 Applicability: All Pilatus Porter PC-6 series aircraft. Requirement:  Retire the horizontal stabiliser; or
            Modify the horizontal stabiliser and inspect for cracks in accordance with a scheme approved by the Authority.

            Note: Aeronautical Designs Australia Pty Ltd EO-934 is an approved scheme for the purpose of this Directive.

 Compliance: Retire before 10000 hours component time in service; or

            Modify and inspect before 10000 hours component time in service. Re-inspect at intervals not exceeding 100 hours.
 Background: The Pilatus Porter horizontal stabiliser has a history of fatigue cracking in service.
            Inspection access to some cracking sites is very restricted.

            This AD gives two options: retire before cracks are likely to start; or improve access and inspect.
