AD 2020-17-15

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 This AD was prompted by a determination that certain airplanes have outdated magnetic variation (MV) tables inside navigation systems. This AD requires revising the existing airplane flight manual (AFM) to update the Flight Management System (FMS), Inertial Reference System (IRS), and Attitude and Heading Reference System (AHRS) limitations. 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\n\nSec. 39.13 (Amended) \n\n0 2.

Discussion \n\n\n\tTransport Canada Civil Aviation (TCCA), which is the aviation authority for Canada, has issued Canadian AD CF-2019-40, dated November 1, 2019 (''Canadian AD CF-2019-40'') (also referred to as the Mandatory Continuing Airworthiness Information, or ''the MCAI''), to correct an unsafe condition for all MHI RJ Aviation ULC (type certificate previously held by Bombardier, Inc.) 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-2020-0206. \n\tThe FAA issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 by adding an AD that would apply to 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. The NPRM published in the Federal Register on March 26, 2020 (85 FR 17036). The NPRM was prompted by a determination that certain airplanes have outdated MV tables inside navigation systems. The NPRM proposed to require revising the existing AFM to update the FMS, IRS, and AHRS limitations. The FAA is issuing this AD to address outdated MV tables inside navigation systems, which can affect the performance of the navigation systems and result in the presentation of misleading magnetic heading references on the Primary Flight Displays (PFDs) and Multi-Function Displays (MFDs), positioning the airplane outside of the terrain and obstacle protection provided by instrument flight procedures and flight route designs (e.g., outdated MV tablescan lead to significantly inaccurate heading, course, and bearing calculations). 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 following presents the comments received on the NPRM and the FAA's response to each comment. \n\nSupport for the NPRM \n\n\n\tThe Airline Pilots Association, International stated its support for the NPRM. \n\nRequest To Refer to the Latest Service Information \n\n\n\tBombardier requested that the FAA refer to the latest service information in the NPRM. Bombardier noted that the proposed rule does not refer to the latest AFM revisions, but acknowledged that the proposed rule does refer to the AFM revisions that introduced changes to the MV tables in the limitations sections of the AFMs. Bombardier listed the current AFM revisions as of the time the comment was submitted. \n\tThe FAA does not agree. This AD does not directly mandate incorporating a specific revision level of the corresponding AFMs, but does require incorporating the information provided in the referenced AFM revisions in paragraph (g) of this AD. The language in paragraph (g) of this AD is designed to allow the incorporation of this information to be accomplished independent of the revision level of the AFM, under the condition that the incorporated information is identical to the information that is provided in the referenced AFM revisions specific in paragraph (g) of this AD. The FAA notes that when this comment was submitted, the information provided by the revisions of the AFMs listed by the commenter was identical to the information provided in the referenced AFM revisions in paragraph (g) of this AD. The FAA has not changed the AD in this regard. \n\nConclusion \n\n\n\tThe FAA reviewed the relevant data, considered the comments 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 Part 51 \n\n\n\tBombardier has issued the following service information, which describes procedures for updating, among other systems, the FMS, IRS, and AHRS. These documents are distinct since they apply to different airplane models. \n\tSection 02-09--Navigation System Limitations, of Chapter 2--LIMITATIONS, of the Bombardier CRJ Series Regional Jet Model CL-600- 2B19 Airplane Flight Manual, CSP A-012, Volume 1, Revision 71A, dated April 26, 2019. \n\tSection 02-09--Navigation System Limitations, of Chapter 2--LIMITATIONS, of the Bombardier CRJ Series Regional Jet Model CL-600- 2C10 (Series 700, 701, 702) Airplane Flight Manual, CSP B-012, Revision 26, dated March 1, 2019. \n\tSection 02-09--Navigation System Limitations, of Chapter 2--LIMITATIONS, of the Bombardier CRJ Series Regional Jet Model CL-600- 2C10 (Series 700, 701, 702) and CL-600-2C11 (Series 550) Airplane Flight Manual, CSP B-012, Revision 28, dated September 18, 2019. \n\tSection 02-09--Navigation System Limitations, of Chapter 2--LIMITATIONS, of the Bombardier CRJ Series Regional Jet Model CL-600- 2D24 (Series 900) and CL-600-2D15 (Series 705) Airplane Flight Manual, CSP C-012, Volume 1, Revision 21, dated March 29, 2019. \n\tSection 02-09--Navigation System Limitations, of Chapter 2--LIMITATIONS, of the Bombardier CRJ Series Regional Jet Model CL-600- 2E25 (Series 1000) Airplane Flight Manual, CSP D-012, Revision 21, dated February 15, 2019. \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 1,072 airplanes of U.S. registry. \n\n((Page 60902)) \n\nThe FAA estimates the following costs to comply with this AD: \n\n\n\tEstimated Costs for Required Actions ---------------------------------------------------------------------------------------------------------------- \n\tCost per Cost on U.S. \n\tLabor cost Parts cost product operators ---------------------------------------------------------------------------------------------------------------- 1 work-hour x $85 per hour = $85............................. $0 $85 $91,120 ---------------------------------------------------------------------------------------------------------------- \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\tThis 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 Executive Order 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.
