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
Thomas Niczky, Aerospace Engineer, Avionics and Electrical Systems
Section, FAA, New York ACO Branch, 1600 Stewart Avenue, Suite 410,

Background
Transport Canada Civil Aviation (TCCA), which is the aviation
authority for Canada, has issued TCCA AD CF-2020-33, dated September
29, 2020 (also referred to after this as the Mandatory Continuing
Airworthiness Information, or the MCAI), to correct an unsafe condition
for certain Bombardier, Inc., Model BD-100-1A10 airplanes. You may
examine the MCAI in the AD docket at https://www.regulations.gov by
searching for and locating Docket No. FAA-2021-0272.
This proposed AD was prompted by a report that certain airplanes
have navigation units with outdated MagVar tables. 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this AD to address outdated MagVar tables inside navigation systems,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, and
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. This
service information describes procedures for revising the existing AFM
to update the FMS limitations. These documents are distinct since they
apply to different airplane configurations.
Flight Management System (FMS) limitation in Section 02-
04--Systems Limitations, of Chapter 02--Limitations, of the Challenger
300 Airplane Flight Manual (Imperial Version), Publication No. CSP 100-
1, Revision 58, dated January 15, 2020. (For obtaining the FMS
limitation for Bombardier Challenger 300 Airplane Flight Manual
(Imperial Version), Publication No. CSP 100-1, use Document
Identification No. CH 300 AFM-I.)
FMS limitation in Section 02-04--Systems Limitations, of
Chapter 02--Limitations, of the Challenger 300 Airplane Flight Manual
(Metric Version), Publication No. CSP 100-1 (Metric), Revision 58,
dated January 15, 2020. (For obtaining the FMS limitation for
Bombardier Challenger 300 Airplane Flight Manual (Metric Version),
Publication No. CSP 100-1 (Metric), use Document Identification No. CH
300 AFM-M.)
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
[[Page 18923]]
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 AD Requirements in This NPRM
This proposed AD would require accomplishing the actions specified
in the service information already described.
Costs of Compliance
The FAA estimates that this AD, if adopted as proposed, would
affect 318 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 $27,030
----------------------------------------------------------------------------------------------------------------
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) Would not affect intrastate aviation in Alaska, and
(3) Would not have a significant economic impact, positive or
negative, on a substantial number of small entities under the criteria
of the Regulatory Flexibility Act.
