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/AC-SNOW/20.

Ayres Thrush (Snow) Commander Series Aeroplanes

AD/AC-SNOW/20 Aileron Hinge Bracket Bolts 9/2008

Requirement:	CANCELLED.
This AD is cancelled on 28 August 2008.
Background:	This AD, raised in 1993 against Ayres Corporation Service Bulletin (SB) No. SB-AG-22, required a modification to increase the fatigue life of the lower aileron bracket attachment by replacing the existing attachment bolts with bolts of a larger diameter.  Compliance was required within 5 flight hours after 21 June 1993.  As all affected aircraft would have been modified by now, this AD is no longer required.
