AIRWORTHINESS DIRECTIVE

On the effective date specified below, and for the reasons set out in the background section, the CASA delegate whose signature appears below revokes Airworthiness Directive AD/BELL 205/57.

Bell Helicopter Textron 205 Series Helicopters

AD/BELL 205/57 Bogus Tension Torsion Straps 2/2009

Requirement:	CANCELLED.
This AD is cancelled on 12 February 2009.
Background:	This unique Australian AD, issued in 1989, required a one off inspection of the tension torsion strap in accordance with Bell Alert Service Bulletin 205-89-33 Revision A to ensure the straps were approved parts.  The AD compliance was prior to 3 November 1989.  As all aircraft would have been inspected by now and the requirements of approved parts are covered by CAR 42W and CASR 21.303, the AD is no longer required.
