## Summary

The FAA withdraws a notice of proposed rulemaking (NPRM) that proposed a new airworthiness directive (AD) for certain The Boeing Company Model 777-200 series airplanes. The proposed AD would have required installing a new circuit breaker, relays, and wiring to allow the flightcrew 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. This proposed AD would also have required installing a new cabin system control panel (CSCP); installing a new cabin management system (CMS) configuration database; and installing new operational program software (OPS) for the CSCP, zone management unit (ZMU), passenger address controller, cabin interphone controller, cabin area control panel (CACP), speaker drive module, overhead electronics units, and seat electronics unit. Since the proposed AD was issued, we have received new data that indicates the unsafe condition would not be adequately addressed by the proposed action. Subsequently, we are considering issuing new rulemaking that positively addresses the unsafe condition identified in the NPRM and eliminates the need for the actions proposed in the NPRM. Accordingly, the proposed AD is withdrawn.
