Airworthiness Directive · Amendment 39-22710 · Time limits/maintenance checks
MHI RJ Aviation ULC (Type Certificate Previously Held by Bombardier, Inc.) Airplanes
This AD applies to all MHI RJ Aviation ULC (Type Certificate previously held by Bombardier, Inc.) Model CL-600-2E25 (Regional Jet Series 1000) airplanes, certificated in any category.
The FAA is adopting a new airworthiness directive (AD) for all MHI RJ Aviation ULC Model CL-600-2E25 (Regional Jet Series 1000) airplanes. This AD was prompted by a determination that new or more restrictive airworthiness limitations are necessary. This AD 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.
Requirements
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-2023-43, dated June 21, 2023 (Transport Canada AD CF-2023-43).
(1) Where Transport Canada AD CF-2023-43 refers to its effective date, this AD requires using the effective date of this AD.
(2) Where paragraph 1. of Transport Canada AD CF-2023-43 specifies to “incorporate the new and revised tasks identified in Table 1 below, in the appropriate chapter within Section 2 and Section 3 of the MRM CSP B-053 Part 2 manual,” this AD requires replacing that text with “revise the existing maintenance or inspection program, as applicable, by incorporating the new and revised tasks identified in Table 1.”
(3) The initial compliance time for doing the tasks specified in paragraph 1. of Transport Canada AD CF-2023-43 is at the applicable “thresholds” and “discard times” as specified in the service information referenced in paragraph 1. of Transport Canada AD CF-2023-43, or within 60 days after the effective date of this AD, whichever occurs later.
(4) This AD does not adopt paragraph 2. of Transport Canada AD CF-2023-43.
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-2023-43.
The following provisions also apply to this AD:
