## Summary

The FAA proposes to adopt a new airworthiness directive (AD) for certain Boeing Model 757-200 and -300 series airplanes. This proposed AD would require 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 proposed AD also requires modification of wiring of the control module assembly for the electrical systems. This proposed AD results from an in-flight entertainment (IFE) systems review. We are proposing this AD to ensure that the flightcrew is able to turn off electrical power to the IFE system through utility bus switches in the flight compartment. The flightcrew's inability to turn off power to the IFE system during a non-normal or emergency situation could result in the inability to control smoke or fumes in the airplane flight deck or cabin.
