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 cCltain Mo

777-200 series airplanes. This proposed AD w6uld require installing a new circuit

breaker, relays, and wiring to allow the flightJew to turn off electrical power to the in

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

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

removing the cabin system control panel (CSCP) core partition software, the cabin are

control panel (CACP) operational program software (OPS), the zone management unit

(ZMU) OPS, and the cabin system management unit (CSMU) OPS; installing OPS for

the CSCP, CACP, ZMU, and CSMU; and installing the new configuration database

I

(COB). This proposed AD would also require installing a new CSCP; installing a new

cabin management system (CMS) CDB; and installing new OPS for the CSCP, ZMU,

passenger address controller, cabin interphone controller, CACP. speaker drive modul

overhead electronics units, and seat electronics unit. This proposed AD results from an

in·flight entertainment (!FE) systems review. We are proposing trus AD to ensure that

the flightcrew is able to turn off electrical power to the lFE system and other nooessential electrical systems through a switch in the flight compartment in the event of
