Airworthiness Directive · Amendment 39-18517 · Navigation
Bombardier, Inc. Airplanes
This AD applies to the Bombardier, Inc. airplanes, certificated in any category, specified in paragraphs (c)(1) and (c)(2) of this AD.
(1) Model BD-700-1A10 airplanes, serial numbers 9381, 9432 through 9708 inclusive; 9711 through 9718 inclusive; and 9720 through 9730 inclusive.
(2) Model BD-700-1A11 airplanes, serial numbers 9386, 9401, 9445 through 9707 inclusive; 9710 through 9717 inclusive; and 9722, 9732, 9734, and 9737.
We are adopting a new airworthiness directive (AD) for certain Bombardier, Inc. Model BD-700-1A10 and BD-700-1A11 airplanes. This 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 AD requires inspecting the network interface installation between the IMS and the CES, and disconnecting the installation, if necessary. We are issuing 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.
Within 15 months after the effective date of this AD: Do a general visual inspection of the network interface installation between the IMS and CES to determine if pins are present at positions 25, 27, 48, and 50; and if any pins are present, before further flight, disconnect the installation; in accordance with the Accomplishment Instructions of the applicable service information specified in paragraph (g)(1) or (g)(2) of this AD.
(1) Bombardier Service Bulletin 700-46-5005, Revision 02, dated June 18, 2015 (for Model BD-700-1A11 airplanes).
(2) Bombardier Service Bulletin 700-46-6005, Revision 02, dated June 18, 2015 (for Model BD-700-1A10 airplanes).
