Twin Commander (Gulfstream/Rockwell/Aerocommander 500, 600 and 700) Series Aeroplanes

AD/AC/73 Wing Fasteners - Modification 8/2008

Requirement:	CANCELLED.
This AD is cancelled on 31 July 2008.
Background:	This unique Australian AD, raised in1981 against Gulfstream American (also known as Aero Commander) Service Bulletin (SB) No. 182, required a modification to provide increased fastener strength by installation of additional and larger fasteners.  Compliance was required within 100 hours TIS after 31 July 1981.  As all affected aircraft would have been inspected, and, if necessary, modified long ago, this AD is no longer required.
