## Summary

We propose to adopt a new airworthiness directive (AD) for certain Bombardier, Inc. Model BD-700-1A10 and BD-700-1A11 airplanes. This proposed AD was prompted by a determination that the network interface installed between the Information Management System (IMS) 6000 unit and the Cabin Entertainment System (CES) network could affect the Aircraft Control Domain (ACD) and result in the transmission of misleading navigational information to the flightcrew. This proposed AD would require inspecting the network interface installation between the IMS and the CES, and disconnecting the installation, if necessary. We are proposing this AD to prevent the transmission of misleading navigational information, which could adversely affect the ability of the flightcrew to maintain the safe flight and landing of the airplane.
