Airworthiness Directive · Amendment 39-22425 · Fire protection
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.) airplanes identified in paragraphs (c)(1) through (6) of this AD, certificated in any category.
(1) Model CL-600-2B19 (Regional Jet Series 100 & 440) airplanes.
(2) Model CL-600-2C10 (Regional Jet Series 700, 701, & 702) airplanes.
(3) Model CL-600-2C11 (Regional Jet Series 550) airplanes.
(4) Model CL-600-2D15 (Regional Jet Series 705) airplanes.
(5) Model CL-600-2D24 (Regional Jet Series 900) airplanes.
(6) Model CL-600-2E25 (Regional Jet Series 1000) airplanes.
The FAA is adopting a new airworthiness directive (AD) for all MHI RJ Aviation ULC Model CL-600-2B19 (Regional Jet Series 100 & 440); 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 aircraft maintenance manual (AMM) tasks and certification maintenance requirement (CMR) tasks are necessary. This AD requires revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive AMM and CMR tasks. The FAA is issuing this AD to address the unsafe condition on these products.
For Model CL-600-2B19 airplanes: Within 60 days after the effective date of this AD, revise the existing maintenance or inspection program, as applicable, to incorporate the information specified in Bombardier Temporary Revisions 2A-73 and 2A-74, both dated June 5, 2020. The initial compliance time for doing the tasks is at the applicable times specified in Bombardier Temporary Revisions 2A-73 and 2A-74, both dated June 5, 2020, or within 60 days after the effective date of this AD, whichever occurs later.
For airplanes identified in paragraphs (c)(2) through (6) of this AD:
(1) Within 60 days after the effective date of this AD, revise the existing maintenance or inspection program, as applicable, to incorporate the information specified in Figure 1 to paragraph (h)(1) of this AD. The initial compliance time for doing the task is at the applicable time specified in paragraph (h)(1)(i) or (ii) of this AD.
(i) If a restoration (previously called a hydrostatic test) of any cargo compartment fire extinguisher bottle was accomplished on or before June 5, 2014, do the applicable maintenance task on that bottle within 48 months after the effective date of this AD.
(ii) If a restoration (previously called a hydrostatic test) of any cargo compartment fire extinguisher bottle was accomplished after June 5, 2014, do the applicable maintenance task on that bottle within 10 years after the most recent restoration was accomplished.

(2) Within 60 days after the effective date of this AD, revise the existing maintenance or inspection program, as applicable, to incorporate the information specified in Figure 2 to paragraph (h)(2) of this AD. The initial compliance time for doing the task is at the applicable time specified in paragraph (h)(2)(i) or (ii) of this AD.
(i) If a restoration (previously called a hydrostatic test) of any engine or auxiliary power unit (APU) fire extinguisher bottle was accomplished on or before June 5, 2014, do the applicable maintenance task on that bottle within 48 months after the effective date of this AD.
(ii) If a restoration (previously called a hydrostatic test) of any engine or APU fire extinguisher bottle was accomplished after June 5, 2014, do the applicable maintenance task on that bottle within 10 years after the most recent restoration was accomplished.

After the existing maintenance or inspection program has been revised as required by paragraphs (g) and (h) 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.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
