This AD applies to all MHI RJ Aviation ULC (Type Certificate Previously Held by Bombardier, Inc.) 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, certificated in any category.
The FAA is adopting a new airworthiness directive (AD) for all MHI RJ Aviation ULC (Type Certificate Previously Held by Bombardier, Inc.) 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 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 60 days after the effective date of this AD, revise the existing maintenance or inspection program, as applicable, to incorporate the tasks identified in figure 1 to paragraph (g) of this AD as specified in MHI RJ Aviation CRJ550/700/705/900/1000 Maintenance Requirements Manual (MRM) Part 2, CSP B-053, Revision 26, dated March 25, 2022. The initial compliance time for doing the tasks is at the applicable times specified in MHI RJ Aviation CRJ550/700/705/900/1000 Maintenance Requirements Manual (MRM) Part 2, CSP B-053, Revision 26, dated March 25, 2022, or within 60 days after the effective date of this AD, whichever occurs later.
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 the actions and intervals are approved as an alternative method of compliance (AMOC) in accordance with the procedures specified in paragraph (j)(1) of this AD.
