MHI RJ Aviation ULC (Type Certificate Previously Held by Bombardier, Inc.) Airplanes
This AD applies to MHI RJ Aviation ULC airplanes identified in paragraphs (c)(1) through (3) of this AD, certificated in any category.
(1) Model CL-600-2C10 (Regional Jet Series 700, 701 & 702) and CL-600-2C11 (Regional Jet Series 550) airplanes, serial numbers 10002 and subsequent.
(2) Model CL-600-2D15 (Regional Jet Series 705) and CL-600-2D24 (Regional Jet Series 900) airplanes, serial numbers 15001 and subsequent.

The FAA is adopting a new airworthiness directive (AD) for certain MHI RJ Aviation ULC Model CL-600-2C10 (Regional Jet Series 700, 701 & 702), CL-600-2C11 (Regional Jet Series 550), CL-600-2D15 (Regional Jet Series 705), CL-600-2D24 (Regional Jet Series 900), and CL-600-2E25 (Regional Jet Series 1000) airplanes. This AD was prompted by a determination that new or more restrictive airworthiness limitations for structural inspections and safe life components are necessary. This AD requires revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive airworthiness limitations. The FAA is issuing this AD to address the unsafe condition on these products.
Within 180 days after the effective date of this AD, revise the existing maintenance or inspection program, as applicable, to incorporate the airworthiness limitations for structural inspections and safe life components specified in paragraphs (g)(1) and (2) of this AD.
(1) The task number, model effectivity, threshold, repeat cut-in, repeat, and task type for the Section 2 structural inspections specified in paragraph 2.B.(2)(a) of the Accomplishment Instructions of MHI RJ Service Bulletin 670BA-05-001, dated August 27, 2020.
(2) The task number, part number, model effectivity, and discard time for the Section 3 safe life components specified in paragraph 2.B.(3)(a) of the Accomplishment Instructions of MHI RJ Service Bulletin 670BA-05-001, dated August 27, 2020.
After the existing maintenance or inspection program has been revised as required by paragraph (g) of this AD, no alternative actions (e.g., inspections) or intervals may be used unless they are approved as specified in the provisions of paragraphs 2.B.(2)(a) and 2.B.(3)(a) of the Accomplishment Instructions of MHI RJ Service Bulletin 670BA-05-001, dated August 27, 2020.
