Airworthiness Directive · Amendment 39-22348 · Doors
Bombardier, Inc., Airplanes
This AD applies to Bombardier, Inc., Model BD-700-2A12 airplanes, certificated in any category, serial numbers 70006 through 70061 inclusive.
The FAA is adopting a new airworthiness directive (AD) for certain Bombardier, Inc., Model BD-700-2A12 airplanes. This AD was prompted by report that the passenger door functional test engineering requirements (FTERs) were not fully accomplished on several airplanes. This AD requires measuring the passenger door steps, passenger door gaps, and passenger door stops rigging, and re-adjusting the door if necessary. The FAA is issuing this AD to address the unsafe condition on these products.
Within 72 months after the effective date of this AD, measure the passenger door steps and gap values on each lateral side of the door at 8 points, and on the lower and upper sides of the door at 4 points, in accordance with Part A of the Accomplishment Instructions of Bombardier Service Bulletin 700-52-7511, dated July 22, 2022. Then accomplish the actions specified by paragraph (g)(1) or (2) of this AD, as applicable.
(1) If any measurement is not within the specified limits, before further flight, re-adjust the passenger door steps and gaps to obtain the acceptable (necessary) values in accordance with Part B of the Accomplishment Instructions of Bombardier Service Bulletin 700-52-7511, dated July 22, 2022.
(2) If all of the measurements are within the specified limits, before further flight, with the door in the closed position, measure the passenger door stops gaps in accordance with Part C of the Accomplishment Instructions of Bombardier Service Bulletin 700-52-7511, dated July 22, 2022. If any passenger door stops gaps measurement is not within the specified limits, before further flight, re-adjust the passenger door stops to obtain the acceptable (necessary) values in accordance with Part D of the Accomplishment Instructions of Bombardier Service Bulletin 700-52-7511, dated July 22, 2022.
Although Bombardier Service Bulletin 700-52-7511, dated July 22, 2022, specifies to submit certain information to the manufacturer, this AD does not include that requirement.
The following provisions also apply to this AD:
(1) Alternative Methods of Compliance (AMOCs): The Manager, New York ACO Branch, FAA, has the authority to approve AMOCs for this AD, if requested using the procedures found in 14 CFR 39.19.
