Airworthiness Directive · Amendment 39-22755 · Time limits/maintenance checks
MHI RJ Aviation ULC (Type Certificate Previously Held by Bombardier, Inc.) Airplanes
This AD applies to MHI RJ Aviation ULC (Type Certificate previously held by Bombardier, Inc.) Model CL-600-2B19 (Regional Jet Series 100 & 440) airplanes, certificated in any category, as identified in Transport Canada AD CF-2023-41, dated June 15, 2023 (Transport Canada AD CF-2023-41).
The FAA is adopting a new airworthiness directive (AD) for certain MHI RJ Aviation ULC Model CL-600-2B19 (Regional Jet Series 100 & 440) airplanes. This AD was prompted by a determination that a more restrictive airworthiness limitation is necessary. This AD requires revising the existing maintenance or inspection program, as applicable, to incorporate a more restrictive airworthiness limitation, 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.
Except as specified in paragraph (h) of this AD: Comply with all required actions and compliance times specified in, and in accordance with, Transport Canada AD CF-2023-41.
(1) Where Transport Canada AD CF-2023-41 refers to its effective date, this AD requires using the effective date of this AD.
(2) Where paragraph A. of Transport Canada AD CF-2023-41 specifies to “incorporate the revised task AWL number 53-41-180 in Appendix B of the MRM CSP A-053 Part 2,” this AD requires replacing that text with “revise the existing maintenance or inspection program, as applicable, by incorporating the revised task AWL number 53-41-180 specified in MHI RJ Temporary Revision 2B-2283, dated March 16, 2023.”
(3) The initial compliance time for doing the task specified in paragraph A. of Transport Canada AD CF-2023-41 is at the applicable “threshold” as specified in the service information referenced in paragraph B. of Transport Canada AD CF-2023-41, or within 60 days after the effective date of this AD, whichever occurs later.
(4) This AD does not adopt paragraph B. of Transport Canada AD CF-2023-41.
After the existing maintenance or inspection program has been revised as required by paragraph (g) of this AD, no alternative actions (e.g., inspections) and intervals are allowed unless they are approved as specified in the provisions of the “Corrective Actions” section of Transport Canada AD CF-2023-41.
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) 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, International Validation Branch, FAA; or Transport Canada; or MHI RJ Aviation ULC's Transport Canada Design Approval Organization (DAO). If approved by the DAO, the approval must include the DAO-authorized signature.
