AD/AC/71 Aft Engine Mount Attachment - Inspection 8/2008

Requirement:	CANCELLED.
This AD is cancelled on 31 July 2008.
Background:	This unique Australian AD, raised in1980, against Rockwell International Service (also known as Aero Commander) Bulletin (SB) No. 173, required an inspection to ensure that the aft engine mount fittings of both engines are properly secured to the engine firewall.  Compliance was required within 100 hours TIS after 31 October 1980.  As all affected aircraft would have been inspected, and, if necessary, modified long ago, this AD is no longer required.
