Airworthiness Directives; MHI RJ Aviation ULC (Type Certificate 
Previously Held by Bombardier, Inc.) Airplanes

AGENCY: Federal Aviation Administration (FAA), Department of 
Transportation (DOT).

ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: 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airplanes have outdated magnetic variation (MV) tables inside 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.

DATES: This AD is effective November 3, 2020.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in this AD as of November 3, 
2020.

SUPPLEMENTARY INFORMATION:

Discussion

    Transport 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.
    The 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 tables can lead 
to significantly inaccurate heading, course, and bearing calculations). 
See the MCAI for additional background information.

Comments

    The 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.

Support for the NPRM

    The Airline Pilots Association, International stated its support 
for the NPRM.

Request To Refer to the Latest Service Information

    Bombardier 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.
    The 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.

Conclusion

    The 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:
    <bullet> Are consistent with the intent that was proposed in the 
NPRM for addressing the unsafe condition; and
    <bullet> Do not add any additional burden upon the public than was 
already proposed in the NPRM.

Authority for This Rulemaking

    Title 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.
    The 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.

Regulatory Findings

    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.
    For the reasons discussed above, I certify that this AD:
    (1) Is not a ``significant regulatory action'' under Executive 
Order 12866,
    (2) Will not affect intrastate aviation in Alaska, and
    (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.
