Airworthiness Directives; The Boeing Company Model 777~200 Series Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

SUMMARY: We propose to adopt a new airworthiness directive (AD) for certain Mo

777-200 series airplanes. This proposed AD would require installing a new circuit

breaker, relays, and wiring to allow the tlightcrew to tum off electrical power to the in~

flight entertaimnent (IFE) systems and other non-essential electrical systems through a

switch in the flight compartment, and doing other specified actions. The actions inelud

replacing the cabin area control panels; changing the wiring; modifying the purser stati n

or the A-4 galley, as applicable; installing new cabin system management unit, cabin a ea

software, as applicable; and making a change to the cabin services system (eSS)

configuration database and installing the new database in the CSS components. This

proposed AD would also require changing the wiring at the cabin management system n

review. We are proposing this AD to ensure that the flightcrew is able to turn off

electrical power to the IFE system and other nln-essential electrical systems through a

switch in the flight compartment in the event Jsmoke or flames. The flightcrew"s

inability to tum off electrical power to the IFE Isystem and other non-essential c1ectTiea
