            This Airworthiness Directive becomes effective on 23 December 2004.

            Background: Boeing has advised that an engine configuration wiring fault could cause the ASCTU to erroneously identify the engine type fitted to the aircraft resulting in an inadvertent commanded shutdown of the engine bleed air distribution systems. This may cause depressurisation of the aircraft and ice build-up on the engine inlets during descent, which could result in ingestion of ice into the engine(s) and consequent loss of thrust on one or more engines.
