AD NUMBER: 2014-11-01

PRODUCT: Certain Boeing Model 777-200 and -300 series airplanes.
ACTION: Final Rule

SUMMARY:  This AD was prompted by reports of smoke or flames in the passenger cabin of various transport category airplanes related to the wiring for the passenger cabin in-flight entertainment (IFE) system, cabin lighting, and passenger seats.

This AD requires installing wiring and making changes to certain electrical load management system (ELMS) panels and other concurrent requirements to ensure the flightcrew is able to turn off electrical power to the IFE systems and other non-essential electrical systems through one or two switches in the flight deck in the event of smoke or flames.

In the event of smoke or flames in the airplane flight deck or passenger cabin, the flightcrew's inability to turn off electrical power to the IFE system and other non-essential electrical systems could result in the inability to control smoke or flames in the airplane flight deck or passenger cabin during a non-normal or emergency situation, and consequent loss of control of the airplane.

DATES: This AD is effective July 8, 2014.
