## Abstract

The FAA is adopting a new airworthiness directive (AD) for certain Boeing Model 757-200 and -300 series airplanes. This AD requires changes to existing wiring; installation of new circuit breakers, relays, relay connectors, and wiring; and replacement of certain circuit breakers with higher-rated circuit breakers. For certain airplanes, this AD also requires modification of wiring of the control module assembly for the electrical systems. This AD results from an in-flight entertainment (IFE) systems review. We are issuing this AD to ensure that the flightcrew is able to turn off electrical power to the IFE system and other non-essential electrical systems through utility bus switches in the flight compartment. The flightcrew's inability to turn off power to the IFE system and other non-essential electrical systems during a non-normal or emergency situation could result in the inability to control smoke or fumes in the airplane flight deck or cabin.
