Commonwealth legislation
This Airworthiness Directive mandates modification of the Passenger Address and Entertainment System Video Control Centre (VCC) wire bundles on affected Boeing 767s to prevent chafing against rudder/elevator control cables—a hazard that could cause arcing or cable severance and reduce controllability. It affects aircraft operators and approved maintenance organisations; compliance (and any required operational testing) is mandatory, paid for by operators, and may require aircraft downtime and approved maintenance actions.

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.
