Airworthiness Directive · Amendment 39-23263 · Indicating/recording system
Bombardier Inc. Airplanes
This AD applies to the Bombardier Inc. airplanes, certificated in any category, listed in paragraphs (c)(1) and (2) of this AD.
(1) Model BD-700-1A10 airplanes, serial numbers 9381, 9432 through 9861 inclusive, 9863 through 9878 inclusive, and 60001 through 61999 inclusive.
(2) Model BD-700-1A11 airplanes, serial numbers 9386, 9401, 9445 through 9862 inclusive, 9868 through 9879 inclusive, and 60007 through 61999 inclusive.
The FAA is adopting a new airworthiness directive (AD) for certain Bombardier Inc. Model BD-700-1A10 and BD-700-1A11 airplanes. The FAA previously sent this AD to all known U.S. owners and operators of these airplanes. This AD was prompted by discrepancies in the locking features on certain network interfaces. This AD requires installing locking features on certain network interfaces to prevent unapproved access to these network interfaces. The FAA is issuing this AD to address the unsafe condition on these products.
Within 6 months after the effective date of this AD, install locking features on the applicable network interfaces using a method approved by the Manager, International Validation Branch, FAA.
