Airworthiness Directive · Amendment 39-22872 · Time limits/maintenance checks
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 airplanes, certificated in any category, as identified in paragraphs (c)(1) and (2) of this AD.
(1) Model BD-500-1A10 airplanes, serial numbers 50001 and subsequent with an original airworthiness certificate or original export certificate of airworthiness issued on or before August 17, 2023.
(2) Model BD-500-1A11 airplanes, serial numbers 55001 and subsequent with an original airworthiness certificate or original export certificate of airworthiness issued on or before August 17, 2023.
The FAA is superseding Airworthiness Directive (AD) 2023-05- 08, which applied to certain Airbus Canada Limited Partnership Model BD-500-1A10 and BD-500-1A11 airplanes. AD 2023-05-08 required revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive airworthiness limitations. This AD was prompted by a determination that new or more restrictive airworthiness limitations are necessary. This AD continues to require certain actions in AD 2023-05-08 and requires revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive airworthiness limitations, as specified in a Transport Canada AD, which is incorporated by reference. The FAA is issuing this AD to address the unsafe condition on these products.
This paragraph restates the requirements of paragraph (g) of AD 2023-05-08, with revised language. For airplanes with an original airworthiness certificate or original export certificate of airworthiness issued on or before June 18, 2020: Within 90 days after March 30, 2021 (the effective date of AD 2021-04-05, Amendment 39-21426 (86 FR 10799, February 23, 2021)), revise the existing maintenance or inspection program, as applicable, to incorporate the information specified in Section 03, “Candidate CMR Limitations—General,” of Airbus Canada Limited Partnership A220 Airworthiness Limitations, BD500-3AB48-11400-02, Issue 011.00, dated June 18, 2020. The initial compliance time for doing the tasks is at the time specified in Airbus Canada Limited Partnership A220 Airworthiness Limitations, BD500-3AB48-11400-02, Issue 011.00, dated June 18, 2020, or within 90 days after March 30, 2021, whichever occurs later.
This paragraph restates the requirements of paragraph (h) of AD 2023-05-08 with revised language. 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, or CDCCLs may be used unless the actions, intervals, and CDCCLs are approved as an alternative method of compliance.
This paragraph restates the requirements of paragraph (i) of AD 2023-05-08, with a new terminating action. For airplanes with an original airworthiness certificate or original export certificate of airworthiness issued on or before February 3, 2022: Within 90 days after May 12, 2023 (the effective date of AD 2023-05-08), revise the existing maintenance or inspection program, as applicable, to incorporate the information specified in Sections 01, “Airworthiness limitations—Introduction;” 02, “Certification maintenance requirements—General;” 04, “ALI structural inspections—General;” 05, “Life limited parts—General;” 06, “Fuel system limitations—General;” 07, “Critical design configuration control limitations—General;” 08, “Power plant limitations—General;” 09, “Structural repair limitations—General;” and 10, “Limit of validity—General;” inclusive of Airbus Canada Limited Partnership A220 Airworthiness Limitations, BD500-3AB48-11400-02, Issue 014.00, dated February 3, 2022. The initial compliance time for doing the tasks is at the time specified in Airbus Canada Limited Partnership A220 Airworthiness Limitations, BD500-3AB48-11400-02, Issue 014.00, dated February 3, 2022, or within 90 days after May 12, 2023, whichever occurs later. Accomplishing the revision of the existing maintenance or inspection program required by paragraph (k) of this AD terminates the requirements of this paragraph.
This paragraph restates the requirements of paragraph (j) of AD 2023-05-08, with a new exception. Except as required by paragraph (k) of this AD, after the existing maintenance or inspection program has been revised as required by paragraph (i) of this AD, no alternative actions (e.g., inspections), intervals, or CDCCLs may be used unless the actions, intervals, and CDCCLs are approved as an alternative method of compliance (AMOC) in accordance with the procedures specified in paragraph (n)(1) of this AD.
Except as specified in paragraph (l) of this AD: Comply with all required actions and compliance times specified in, and in accordance with, Transport Canada AD CF-2023-69, dated October 5, 2023 (Transport Canada AD CF-2023-69). Accomplishing the revision of the existing maintenance or inspection program required by this paragraph terminates the requirements of paragraph (i) of this AD.
(1) Where Transport Canada AD CF-2023-69 refers to its effective date, this AD requires using the effective date of this AD.
(2) Where paragraph A. of Transport Canada AD CF-2023-69 specifies to “amend the TC-approved maintenance schedule,” this AD requires replacing that text with “revise the existing maintenance or inspection program, as applicable.”
(3) Where paragraph A. of Transport Canada AD CF-2023-69 specifies incorporating Airbus Canada Limited Partnership A220 Airworthiness Limitations, BD500-3AB48-11400-02, Issue 017.01, dated August 17, 2023, for this AD, incorporating the information specified in Section 03, “Candidate CMR Limitations—General” of Airbus Canada Limited Partnership A220 Airworthiness Limitations, BD500-3AB48-11400-02, Issue 017.01, dated August 17, 2023, is not required.
(4) The initial compliance time for doing the tasks specified in paragraph A. of Transport Canada AD CF-2023-69 is at the applicable “thresholds” as incorporated by the requirements of paragraph A. of Transport Canada AD CF-2023-69, or within 90 days after the effective date of this AD, whichever occurs later.
(5) This AD does not adopt paragraph B. of Transport Canada AD CF-2023-69.
After the existing maintenance or inspection program has been revised as required by paragraph (k) of this AD, no alternative actions (e.g., inspections), intervals, or CDCCLs may be used unless they are approved as specified in the provisions of the “Corrective Actions” section of Transport Canada AD CF-2023-69.

(iii) AMOCs approved previously for AD 2023-05-08 are approved as AMOCs for the corresponding provisions of paragraph (k) of this AD, except AMOCs that allow issues earlier than Airbus Canada Limited Partnership A220 Airworthiness Limitations, BD500-3AB48-11400-02, Issue 017.01, dated August 17, 2023.
(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 Airbus Canada Limited Partnership's Transport Canada Design Approval Organization (DAO).
