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airplanes have outdated magnetic variation (MV) tables inside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:
Are consistent with the intent that was proposed in the
NPRM for addressing the unsafe condition; and
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.
