AD 2021-11-02

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.

Final rule.

Adoption of the Amendment \n\n\n\tAccordingly, under the authority delegated to me by the Administrator, the FAA amends 14 CFR part 39 as follows: \n\nPART 39--AIRWORTHINESS DIRECTIVES \n\n0 1. The authority citation for part 39 continues to read as follows: \n\n\n\tAuthority: 49 U.S.C. 106(g), 40113, 44701. \n\n((Page 30385)) \n\nSec. 39.13 (Amended) \n\n0 2. The FAA amends Sec. 39.13 by: 0 a. Removing Airworthiness Directive (AD) 2019-22-07, Amendment 39-19786 (85 FR 439, January 6, 2020); and 0 b. Adding the following new AD: \n\n2021-11-02 MHI RJ Aviation ULC (Type Certificate Previously Held by Bombardier, Inc.): Amendment 39-21564; Docket No. FAA-2021-0098; Project Identifier MCAI-2020-01121-T. \n\n(a) Effective Date \n\n\n\tThis airworthiness directive (AD) is effective July 13, 2021. \n\n(b) Affected ADs \n\n\n\tThis AD replaces AD 2019-22-07, Amendment 39-19786 (85 FR 439, January 6, 2020) (AD 2019-22-07). \n\n(c) Applicability \n\n\n\tThis AD applies to the MHI RJ Aviation ULCairplanes identified in paragraphs (c)(1) through (6) of this AD, certificated in any category, all manufacturer serial numbers. \n\t(1) Model CL-600-2B19 (Regional Jet Series 100 & 440) airplanes. \n\t(2) Model CL-600-2C10 (Regional Jet Series 700, 701 & 702) airplanes. \n\t(3) Model CL-600-2C11 (Regional Jet Series 550) airplanes. \n\t(4) Model CL-600-2D15 (Regional Jet Series 705) airplanes. \n\t(5) Model CL-600-2D24 (Regional Jet Series 900) airplanes. \n\t(6) Model CL-600-2E25 (Regional Jet Series 1000) airplanes. \n\n(d) Subject \n\n\n\tAir Transport Association (ATA) of America Code 22, Auto Flight. \n\n(e) Reason \n\n\n\tThis AD was prompted by a report that during the Automatic Flight Control System (AFCS) ALTS CAP, (V) ALTS CAP, or (V) ALTV CAP mode, the flight guidance/autopilot does not account for engine failure while capturing an altitude.

Background \n\n\n\tTransport 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. \n\tThe 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) \n\n((Page 30384)) \n\nairplanes. 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 whilein 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. \n\nComments \n\n\n\tThe FAA gave the public the opportunity to participate in developing this final rule. The FAA has considered the comment received. The Air Line Pilots Association, International (ALPA) stated that it supports the NPRM. \n\nConclusion \n\n\n\tThe FAA reviewed the relevant data, considered the comment received, and determined that air safety and the public interest require adopting this final rule as proposed, except for minor editorial changes. The FAA has determined that these minor changes: \n\tAre consistent with the intent that was proposed in the NPRM for addressing the unsafe condition; and \n\tDo not add any additional burden upon the public than was already proposed in the NPRM. \n\nRelated Service Information Under 1 CFR Part51 \n\n\n\tBombardier has issued the following service information, which describes procedures for revising the existing AFM by including a limitation that specifies a warning for the AFCS and an abnormal operating procedure if an engine failure occurs during or before a climb while in ALTS CAP mode, (V) ALTS CAP mode, or (V) ALTV CAP mode, as applicable. These documents are distinct since they apply to different airplane models. \n\tSection 02-08, ''System Limitations,'' of Chapter 2, ''LIMITATIONS''; and Section 05-02, ''In-Flight Engine Failures,'' of Chapter 5, ''ABNORMAL PROCEDURES''; of the Bombardier CRJ Series Regional Jet Model CL-600-2B19 AFM, CSP A-012, Volume 1, Revision 73, dated January 3, 2020. \n\tSection 02-08, ''System Limitations,'' of Chapter 2, ''LIMITATIONS''; and Section 05-02, ''In-Flight Engine Failures,'' of Chapter 5, ''ABNORMAL PROCEDURES''; of the Bombardier CRJ Series Regional Jet Model CL-600-2C10 (Series 700, 701, 702) and CL-600-2C11 (Series 550) AFM, CSPB-012, Revision 31, dated May 8, 2020. \n\tSection 02-08, ''System Limitations,'' of Chapter 2, ''LIMITATIONS''; and Section 05-02, ''In-Flight Engine Failures,'' of Chapter 5, ''ABNORMAL PROCEDURES''; of the Bombardier CRJ Series Regional Jet Model CL-600-2D24 (Series 900) and CL-600-2D15 (Series 705) AFM, CSP C-012, Volume 1, Revision 24, dated March 27, 2020. \n\tSection 02-08, ''System Limitations,'' of Chapter 2, ''LIMITATIONS''; and Section 05-02, ''In-Flight Engine Failures,'' of Chapter 5, ''ABNORMAL PROCEDURES''; of the Bombardier CRJ Series Regional Jet Model CL-600-2E25 (Series 1000) AFM, CSP D-012, Revision 23, dated February 14, 2020. \n\tThis service information is reasonably available because the interested parties have access to it through their normal course of business or by the means identified in the ADDRESSES section. \n\nCosts of Compliance \n\n\n\tThe FAA estimates that this AD affects 992 airplanes of U.S. registry. \n\tThe FAA estimates the following costs to complywith this AD: \n\n\n\tEstimated Costs for Required Actions ---------------------------------------------------------------------------------------------------------------- \n\tCost per Cost on U.S. \n\tAction Labor cost Parts cost product operators ---------------------------------------------------------------------------------------------------------------- New actions........................ 1 work-hour x $85 per hour $0 $85 $84,320 \n\t= $85. ---------------------------------------------------------------------------------------------------------------- \n\nAuthority for This Rulemaking \n\n\n\tTitle 49 of the United States Code specifies the FAA's authority to issue rules on aviation safety. Subtitle I, section 106, describes the authority of the FAA Administrator. Subtitle VII: Aviation Programs, describes in more detail the scope of the Agency's authority. \n\tThe FAA is issuing this rulemaking under the authority described in Subtitle VII, Part A, Subpart III, Section 44701: General requirements. Under that section, Congress charges the FAA with promoting safe flight of civil aircraft in air commerce by prescribing regulations for practices, methods, and procedures the Administrator finds necessary for safety in air commerce. This regulation is within the scope of that authority because it addresses an unsafe condition that is likely to exist or develop on products identified in this rulemaking action. \n\nRegulatory Findings \n\n\n\tThe FAA determined that this AD will not have federalism implications under Executive Order 13132. This AD will not have a substantial direct effect on the States, on the relationship between the national government and the States, or on the distribution of power and responsibilities among the various levels of government. \n\tFor the reasons discussed above, I certify that this AD: \n\t(1) Is not a ''significant regulatory action'' under ExecutiveOrder 12866, \n\t(2) Will not affect intrastate aviation in Alaska, and \n\t(3) Will not have a significant economic impact, positive or negative, on a substantial number of small entities under the criteria of the Regulatory Flexibility Act. \n\nList of Subjects in 14 CFR Part 39 \n\n\n\tAir transportation, Aircraft, Aviation safety, Incorporation by reference, Safety.
