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.

            This amendment provides relief from the Requirement 2 MEL restriction by identifying a Service Bulletin which provides for the installation of DDRMI P/N 63543-253-3.

            This original issue of this Airworthiness Directive became effective on 30 October 2002.
