AIRWORTHINESS DIRECTIVE

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.

Delegate of the Civil Aviation Safety Authority
