Airworthiness Directive · Amendment 39-22269 · Doors
Bombardier, Inc., Airplanes
This AD applies to Bombardier, Inc., Model BD-700-1A10 and BD-700-1A11 airplanes, certificated in any category, serial numbers (S/Ns) 9002 through 9998 inclusive, and S/Ns 60001 through 60045 inclusive.
The FAA is adopting a new airworthiness directive (AD) for certain Bombardier, Inc., Model BD-700-1A10 and BD-700-1A11 airplanes. This AD was prompted by reports of the passenger door failing to dampen during opening at regularly scheduled maintenance checks, causing the door to open more rapidly than normal. An investigation found that a contributing factor was erroneous aircraft maintenance manual (AMM) procedures. This AD prohibits using certain versions of certain AMM tasks for the passenger door. The FAA is issuing this AD to address the unsafe condition on these products.
As of 30 days after the effective date of this AD, when performing the maintenance tasks identified in figure 1 to paragraph (g) of this AD, do not use any version of any task identified in figure 1 to paragraph (g) of this AD that was issued prior to May 19, 2021.
