Airworthiness Directive · Amendment 39-23141 · Autoflight
Airbus Canada Limited Partnership (Type Certificate Previously Held by C Series Aircraft Limited Partnership (CSALP); Bombardier, Inc.) Airplanes
This AD applies to Airbus Canada Limited Partnership (type certificate previously held by C Series Aircraft Limited Partnership (CSALP); Bombardier, Inc.) Model BD-500-1A10 and Model BD-500-1A11 airplanes, certificated in any category, as identified in Transport Canada AD CF-2024-36, dated October 22, 2024 (Transport Canada AD CF-2024-36).
The FAA is superseding Airworthiness Directive (AD) 2022-25- 51, which applied to all Airbus Canada Limited Partnership Model BD- 500-1A10 and Model BD-500-1A11 airplanes. AD 2022-25-51 required revising the Limitations section of the existing airplane flight manual (AFM) to include a new warning and a new limitation. Since the FAA issued AD 2022-25-51, updated primary flight control computer (PFCC) software has been developed to address the unsafe condition. This AD continues to require the actions in AD 2022-25-51, requires installing the updated PFCC software, which terminates the AFM revision, and removes airplanes from the applicability. The FAA is issuing this AD to address the unsafe condition on these products.
This paragraph restates the requirements of paragraph (g) of AD 2022-25-51, with no changes. Within 7 days after December 27, 2022 (the effective date of AD 2022-25-51), revise the Limitations section of the existing airplane flight manual (AFM) to include the information specified in figure 1 to paragraph (g) of this AD. This may be accomplished by inserting a copy of figure 1 to paragraph (g) of this AD into the existing AFM. Using an AFM revision that includes information identical to that in figure 1 to paragraph (g) of this AD is acceptable for compliance with the requirement of this paragraph.
Except as specified in paragraph (i) of this AD: Comply with all required actions and compliance times specified in, and in accordance with, Transport Canada AD CF-2024-36. Accomplishing the software installation required by paragraph A. of Part II of Transport Canada AD CF-2024-36 terminates the AFM revision required by paragraph (g) of this AD.
(1) This AD does not adopt the requirements of Part I of Transport Canada AD CF-2024-36.
(2) Where Transport Canada AD CF-2024-36 refers to its effective date, this AD requires using the effective date of this AD.
(3) For the airplanes identified in the “Concurrent requirements” paragraph of the material referenced in Transport Canada AD CF-2024-36: At the applicable time specified in paragraph (i)(3)(i) or (ii) of this AD, accomplish the concurrent PFCC software update specified in the material referenced in Transport Canada AD CF-2024-36.
(i) For airplanes identified in AD 2023-12-09, Amendment 39-22467 (88 FR 42606, July 3, 2023) (AD 2023-12-09): Prior to or concurrently with the installation specified in paragraph A. of Part II of Transport Canada AD CF-2024-36 but no later than the compliance time specified in AD 2023-12-09.
(ii) For airplanes not identified in AD 2023-12-09: Prior to or concurrently with the installation specified in paragraph A. of Part II of Transport Canada AD CF-2024-36.
The following provisions also apply to this AD:
(1) Alternative Methods of Compliance (AMOCs): The Manager, AIR-520, Continued Operational Safety 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 Continued Operational Safety Branch, send it to the attention of the person identified in paragraph (k) of this AD and email to: AMOC@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, AIR-520, Continued Operational Safety Branch, FAA; or Transport Canada; or Airbus Canada Limited Partnership's Transport Canada Design Approval Organization (DAO). If approved by the DAO, the approval must include the DAO-authorized signature.
