Summary
This document proposes the adoption of a new airworthiness directive (AD) that is applicable to all Boeing Model 767-300 series airplanes modified by supplemental type certificate SA7019NM-D. This proposal would require modification of the in-flight entertainment (IFE) system to install a switch to remove power from the IFE system and revision of flight crew and cabin crew procedures. This action is necessary to ensure that the flight crew and cabin crew are able to remove electrical power from the IFE system when necessary and are advised of appropriate procedures for such action. Inability to remove power from the IFE system during a non-normal or emergency situation could result in inability to control smoke or fumes in the airplane flight deck or cabin. This action is intended to address the identified unsafe condition.
