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/A320/2. Airbus Industrie A319, A320 and A321 Series Aeroplanes AD/A320/2 Ram Air Turbine Airborne Ground Checkout Module (AGCM) 10/2009 Requirement: CANCELLED. This AD is cancelled on 24 September 2009. Background: This unique Australian AD raised in 1989 against Dowty Rotol Service Bulletin (SB) No. 600-29-63 required a modification to pressure switch fitted to RAM Airborne Ground Checkout Module (AGCM) to prevent the snubber (pulse modulator) in the pressure switch becoming detached and migrating to other areas of the hydraulic system. Compliance was: Prior to 30 September 1989. This AD has been sufficiently promulgated for the affected aircraft to have been modified by now; therefore this AD is considered to be no longer required.
