Airworthiness Directive · Amendment 39-22431 · Pneumatic
Bombardier, Inc., Airplanes
This AD applies to Bombardier, Inc., Model BD-700-2A12 airplanes, certificated in any category, serial numbers 70032, 70047 through 70056 inclusive, 70058 through 70061 inclusive, and 70063 through 70075 inclusive.
The FAA is adopting a new airworthiness directive (AD) for certain Bombardier, Inc., Model BD-700-2A12 airplanes. This AD was prompted by a report that certain environmental control system (ECS) pre-cooler clamp assemblies may not conform to specifications. This AD requires an inspection of the pre-cooler clamps and replacement of non- conforming pre-cooler clamps. The FAA is issuing this AD to address the unsafe condition on these products.
Within 36 months after the effective date of this AD: Identify and replace, as applicable, the ECS pre-cooler clamps in accordance with the Accomplishment Instructions of Bombardier Service Bulletin 700-36-7504, dated June 27, 2022.
Although Bombardier Service Bulletin 700-36-7504, dated June 27, 2022, specifies to submit certain information to the manufacturer or discard affected clamps, 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. 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 New York ACO Branch, mail it to ATTN: Program Manager, Continuing Operational Safety, at the address identified in paragraph (j)(2) of this AD or email to: 9-avs-nyaco-cos@faa.gov. If mailing information, also submit information by email. 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, New York ACO Branch, FAA; or Transport Canada (TC); or Bombardier, Inc.'s TC Design Approval Organization (DAO). If approved by the DAO, the approval must include the DAO-authorized signature.
