Airworthiness Directive · Amendment 39-22730 · 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 60065 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 the discovery that existing maintenance tasks do not detect the potential failure of the passenger door detent mechanism because there is no procedure for inspecting the passenger door locking mechanism. This AD requires revising the maintenance or inspection program, as applicable, to require use of a certain aircraft maintenance manual (AMM) task during accomplishment of a specified maintenance check. The FAA is issuing this AD to address the unsafe condition on these products.
Within 30 days after the effective date of this AD, revise the existing maintenance or inspection program, as applicable, to use the information specified in Aircraft Maintenance Manual (AMM) Task 52-11-00-720-801, “Functional Test of the Passenger Door Mechanism,” Subject 52-11-00, “Passenger Door,” Chapter 52, “Doors,” of the applicable AMMs identified in figure 1 to paragraph (g) of this AD, when performing time limited maintenance check item 52-11-00-201.
After revising the maintenance or inspection program as required by paragraph (g) of this AD, it is prohibited to use AMM Task 52-11-00-720-801, dated May 19, 2022, or earlier.
After the existing maintenance or inspection program has been revised as required by paragraph (g) of this AD, no alternative actions (e.g., inspections), intervals, may be used unless the actions, intervals, are approved as an alternative method of compliance (AMOC) in accordance with the procedures specified in paragraph (j)(1) of this AD.
The following provisions also apply to this AD:
(1) Alternative Methods of Compliance (AMOCs): The Manager, International Validation Branch, FAA, has the authority to approve AMOCs for this AD, if requested using the procedures found in 14 CFR 39.19. In accordance with 14 CFR 39.19, send your request to your principal inspector or responsible Flight Standards Office, as appropriate. If sending information directly to the manager of the International Validation Branch, mail it to the address identified in paragraph (k)(2) of this AD. Information may be emailed to: 9-AVS-NYACO-COS@faa.gov. Before using any approved AMOC, notify your appropriate principal inspector, or lacking a principal inspector, the manager of the responsible Flight Standards Office.
(2) Contacting the Manufacturer: For any requirement in this AD to obtain instructions from a manufacturer, the instructions must be accomplished using a method approved by the Manager, International Validation Branch, FAA; or Transport Canada or Bombardier, Inc.'s Transport Canada Design Approval Organization (DAO). If approved by the DAO, the approval must include the DAO-authorized signature.
