AD 2021-11-02 Requires Revising The Existing AFM And Adding Airplanes To The Applicability

The FAA is superseding Airworthiness Directive (AD) 2019-22-07, which applied to all MHI RJ Aviation ULC Model CL-600-2B19 (Regional Jet Series 100 & 440) airplanes, Model CL-600-2C10 (Regional Jet Series 700, 701 & 702) airplanes, Model CL-600-2D15 (Regional Jet Series 705) airplanes, Model CL-600-2D24 (Regional Jet Series 900) airplanes, and Model CL-600-2E25 (Regional Jet Series 1000) airplanes.

AD 2019-22-07 required revising the existing airplane flight manual (AFM) to include a limitation and an abnormal operating procedure for the Automatic Flight Control System (AFCS). This AD requires revising the existing AFM and adding airplanes to the applicability. This AD was prompted by a finding that the limitation and abnormal operating procedure did not include reference to a certain mode. The FAA is issuing this AD to address the unsafe condition on these products.
DATES: This AD is effective July 13, 2021.

Supplementary Information: Transport Canada Civil Aviation (TCCA), which is the aviation authority for Canada, has issued TCCA AD CF-2018-32R1, dated August 21, 2020 (also referred to as the Mandatory Continuing Airworthiness Information, or the MCAI), to correct an unsafe condition 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. You may examine the MCAI in the AD docket on the internet at https://www.regulations.gov by searching for and locating Docket No. FAA-2021-0098.

The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to supersede AD 2019-22-07, Amendment 39-19786 (85 FR 439, January 6, 2020) (AD 2019-22-07). AD 2019-22-07 applied to all MHI RJ Aviation ULC Model CL-600-2B19 (Regional Jet Series 100 & 440) airplanes, Model CL-600-2C10 (Regional Jet Series 700, 701 & 702) airplanes, Model CL-600-2D15 (Regional Jet Series 705) airplanes, Model CL-600-2D24 (Regional Jet Series 900) airplanes, and Model CL-600-2E25 (Regional Jet Series 1000) airplanes. The NPRM published in the Federal Register on February 24, 2021 (86 FR 11165).

The NPRM was prompted by a finding that the limitation and abnormal operating procedure did not include reference to (V) ALTV CAP mode and a finding that the MHI RJ Aviation ULC Model CL-600-2C11 (Regional Jet Series 550) airplanes are also affected by the same unsafe condition (Model CL-600-2B19 airplanes do not have (V) ALTS CAP or (V) ALTV CAP mode). The risk of the unsafe condition also exists during (V) ALTV CAP mode. The NPRM proposed to require revising the existing AFM and adding airplanes to the applicability. The FAA is issuing this AD to address an engine failure, if it occurs during or before a climb while in ALTS CAP, (V) ALTS CAP, or (V) ALTV CAP mode, which may cause the airspeed to drop significantly below the safe operating speed, possibly resulting in reduced control of the airplane. See the MCAI for additional background information.
