Compliance: For Requirement 1 - Within 6 months after the effective date of this Directive. For Requirement 2 - Before further flight after accomplishment of Requirement 1. This Airworthiness Directive becomes effective on 4 September 2003. Boeing 767 Series Aeroplanes AD/B767/186 (continued) Background: This Directive requires the modification of the passenger address and entertainment system VCC wire bundles and, if necessary, an operational test. This action is necessary to prevent chafing of the wire bundles of the VCC against the rudder and/ or elevator control cables, which could result in arcing of the wires in the wire bundles and severing of the cables. Severed cables, if combined with an engine-out during takeoff, or a high crosswind during takeoff or landing, could result in reduced controllability of the aeroplane.
