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 and -300 series airplanes. The proposed AD would have required installing new operational software in the cabin management system, and loading new software into the mass memory card. 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 Accordingly, the proposed AD is withdrawn.
