[Docket No. FAA-2020-1034; Project Identifier MCAI-2020-00951-T]
RIN 2120-AA64
Airworthiness Directives; Bombardier Inc., Airplanes
AGENCY: Federal Aviation Administration (FAA), DOT.
ACTION: Notice of proposed rulemaking (NPRM).
-----------------------------------------------------------------------
SUMMARY: The FAA proposes to adopt a new airworthiness directive (AD)
for certain Bombardier Inc., Model CL-600-2B16 (601-3A, 601-3R, and 604
Variants) airplanes. This proposed AD was prompted by a determination
that certain airplanes have outdated magnetic variation (MagVar) tables
inside navigation systems. This proposed AD would require revising the
existing airplane flight manual (AFM) to update the Flight Management
System (FMS) and Inertial Reference System (IRS) limitations. The FAA
is proposing this AD to address the unsafe condition on these products.
DATES: The FAA must receive comments on this proposed AD by January 11,
2021.
ADDRESSES: You may send comments, using the procedures found in 14 CFR
11.43 and 11.45, by any of the following methods:

SUPPLEMENTARY INFORMATION:
Comments Invited
The FAA invites you to send any written relevant data, views, or
arguments about this proposal. Send your comments to an address listed
under the ADDRESSES section. Include ``Docket No. FAA-2020-1034;
Project Identifier MCAI-2020-00951-T'' at the beginning of your
comments. The most helpful comments reference a specific portion of the
proposal, explain the reason for any recommended change, and include
supporting data. The FAA will consider all comments received by the
closing date and may amend the proposal because of those comments.
Except for Confidential Business Information (CBI) as described in

https://www.regulations.gov, including any
[[Page 75967]]
personal information you provide. The agency will also post a report
summarizing each substantive verbal contact received about this
proposed AD.
Confidential Business Information
CBI is commercial or financial information that is both customarily
and actually treated as private by its owner. Under the Freedom of
Information Act (FOIA) (5 U.S.C. 552), CBI is exempt from public
disclosure. If your comments responsive to this NPRM contain commercial
or financial information that is customarily treated as private, that
you actually treat as private, and that is relevant or responsive to
this NPRM, it is important that you clearly designate the submitted
comments as CBI. Please mark each page of your submission containing
CBI as ``PROPIN.'' The FAA will treat such marked submissions as
confidential under the FOIA, and they will not be placed in the public
docket of this NPRM. Submissions containing CBI should be sent to
Steven Dzierzynski, Aerospace Engineer, Avionics and Electrical Systems
Services Section, FAA, New York ACO Branch, 1600 Stewart Avenue, Suite
410, Westbury, NY 11590; phone: 516-228-7367; fax: 516-794-5531; email:
[email protected]. Any commentary that the FAA receives which is
not specifically designated as CBI will be placed in the public docket
for this rulemaking.
Discussion
Transport Canada Civil Aviation (TCCA), which is the aviation
authority for Canada, has issued Canadian AD CF-2020-24, dated July 10,
2020 (referred to after this as the Mandatory Continuing Airworthiness
Information, or ``the MCAI''), to correct an unsafe condition for
certain Bombardier Inc., Model CL-600-2B16 (601-3A, 601-3R, and 604
Variants) 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-2020-1034.
This proposed AD was prompted by a determination that certain
airplanes have outdated MagVar tables inside navigation systems. The
FAA is proposing this AD to address outdated MagVar 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 MagVar tables can lead to significantly
inaccurate heading, course, and bearing calculations). See the MCAI for
additional background information.
Related Service Information Under 1 CFR Part 51
Bombardier has issued the following service information, which
provides procedures for updating, among other systems, the FMS and IRS
of the applicable AFM. These documents are distinct since they apply to
different airplane configurations.
Section 02-09, Navigation Systems Limitations, of Chapter
2--LIMITATIONS, of the Bombardier Challenger CL-604 AFM, PSP 604-1,
Revision 116, dated December 18, 2019.
Section 02-09, Navigation Systems Limitations, of Chapter
2--LIMITATIONS, Bombardier Challenger CL-605 AFM, PSP 605-1, Revision
54, dated December 18, 2019.
This 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.
FAA's Determination
This product has been approved by the aviation authority of another
country, and is approved for operation in the United States. Pursuant
to the FAA's bilateral agreement with the State of Design Authority,
the FAA has been notified of the unsafe condition described in the MCAI
and service information referenced above. The FAA is proposing this AD
because the FAA evaluated all the relevant information and determined
the unsafe condition described previously is likely to exist or develop
on other products of the same type design.
Proposed Requirements of This NPRM
This proposed AD would require revising the existing AFM to update
the FMS and IRS limitations of the applicable AFM.
Costs of Compliance
The FAA estimates that this proposed AD affects 39 airplanes of
U.S. registry. The FAA estimates the following costs to comply with
this proposed AD:
Estimated Costs for Required Actions
----------------------------------------------------------------------------------------------------------------
Cost per Cost on U.S.
Labor cost Parts cost product operators
----------------------------------------------------------------------------------------------------------------
1 work-hour x $85 per hour = $85............................. $0 $85 $3,315
----------------------------------------------------------------------------------------------------------------
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
The FAA determined that this proposed AD would not have federalism
implications under Executive Order 13132. This proposed AD would 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 this proposed
regulation:
(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.
