AD 2002-458(B) R2 refers.

 Compliance: For Requirement 1 - Remains unchanged as 'Before 2 October 2002'.

            For Requirement 2 - As of the effective date of this Amendment. This Amendment becomes effective on 19 February 2004.
            Background: Airbus received reports from two operators advising of DDRMI circuit breakers tripping, followed by loss of VOR and DME sources for navigation and displays. Investigations showed the DDRMI power transformer had short circuited, leading to leakage of 115 VAC to systems connected to the DDRMI ARINC 429 busses.

            The original issue of this Directive required temporary deactivation of the DDRMI to prevent possible loss of essential equipment due to an in-flight failure of the DDRMI.

            Amendment 1 extended the range of affected aircraft to aircraft that may have DDRMI version B power transformers.

            Amendment 2 introduces a reference to SB A320-34-1264 Revision 1 as an alternate method of incorporating modification 32414 or 32415 or 32416 or 32417.

            This Amendment corrects the issue date of AOT 34A1262 Revision 01.

            The original issue of this Airworthiness Directive became effective on 29 March 2002.

            Amendment 1 of this Airworthiness Directive became effective on 25 September 2002.

            Amendment 2 of this Airworthiness Directive became effective on 22 January 2004.
