            Note 2: FAA AD 94-15-05 and FAA Alternative Means of Compliance (AMOC) document reference 99-140s-295, dated 13 August 1999, issued by the FAA Transport Airplane Directorate, Aircraft Certification Section, Renton, Washington, refer.

            This Amendment becomes effective on 22 January 2004.

            Background: This amendment changes the reference to terminating actions for the CDU cone brake functional test from AD/B747/231 Amdt 1 to AD/B747/298.

            This Directive was prompted by a FAA/Boeing investigation to determine the controllability of model 747 series aeroplanes following in-flight thrust reverser deployment. The actions specified in this Directive are intended to ensure the integrity of the fail-safe features of the thrust reverser system by preventing possible failure modes in the thrust reverser control system that could result in inadvertent deployment of a thrust reverser during flight.

            Amendment 1 of this Directive was issued to correct an error in the Alternate Means of Compliance paragraph of this Directive.

            The original issue of this Airworthiness Directive became effective on 5 September 2002.
