Abstract
The FAA is adopting a new airworthiness directive (AD) for certain Bombardier, Inc., Model BD-100-1A10 airplanes. This AD was prompted by a report that certain airplanes have navigation units with outdated magnetic variation (MagVar) tables. This AD requires revising the existing airplane flight manual (AFM) and applicable corresponding operational procedures to update the flight management system (FMS) limitations. The FAA is issuing this AD to address the unsafe condition on these products.

SUPPLEMENTARY INFORMATION:
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 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 on the internet at <a href="https://www.regulations.gov">https://www.regulations.gov</a> by
searching for and locating Docket No. FAA-2021-0272.
The FAA issued a notice of proposed rulemaking (NPRM) to amend 14
CFR part 39 by adding an AD that would apply to certain Bombardier,
Inc., Model BD-100-1A10 airplanes. The NPRM published in the Federal
Register on April 12, 2021 (86 FR 18921). The NPRM was prompted by a
report that certain airplanes have navigation units with outdated
MagVar tables. The NPRM proposed to require revising the existing AFM
and applicable corresponding operational procedures to update the FMS
limitations. The FAA is issuing this AD to address outdated MagVar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.
Comments
The FAA gave the public the opportunity to participate in
developing this final rule. The FAA received no comments on the NPRM or
on the determination of the cost to the public.
Conclusion
The FAA reviewed the relevant data 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.
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.

04--Systems Limitations, of Chapter 02--Limitations, of the Bombardier
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

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.
Costs of Compliance
The FAA estimates that this AD affects 318 airplanes of U.S.
registry. The FAA estimates the following costs to comply with this 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
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.

Adoption of the Amendment
Accordingly, under the authority delegated to me by the
Administrator, the FAA amends 14 CFR part 39 as follows:
PART 39--AIRWORTHINESS DIRECTIVES
0
1. The authority citation for part 39 continues to read as follows:
Authority: 49 U.S.C. 106(g), 40113, 44701.
Sec. 39.13 [Amended]
0
2. The FAA amends Sec. 39.13 by adding the following new airworthiness
directive:

2021-0272; Project Identifier MCAI-2020-01485-T.
(a) Effective Date
This airworthiness directive (AD) is effective August 24, 2021.
(b) Affected ADs
None.
(c) Applicability
This AD applies to Bombardier, Inc., Model BD-100-1A10
airplanes, certificated in any category, serial numbers 20003
through 20407 inclusive, equipped with FMC-5000 flight management
computers.

navigation units with outdated magnetic variation (MagVar) tables.
The FAA is issuing 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.

Within 60 days after the effective date of this AD: Revise the
existing AFM and applicable corresponding operational procedures to
incorporate the information specified in the Flight Management
System (FMS) limitation in Section 02-04--Systems Limitations, of
Chapter 02--Limitations, of the applicable AFM, specified in figure
1 to paragraph (g) of this AD.
