This proposed AD was prompted by a determination that certain airplanes have outdated MagVar tables inside navigation systems. The FAA is proposing this AD to address outdated MagVar tables inside navigation systems, which can affect the performance of the navigation systems and result in the presentation of misleading magnetic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outside of the terrain and obstacle protection provided by instrument flight procedures and flight route designs (e.g., outdated MagVar tables can lead to significantly inaccurate heading, course, and bearing calculations).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— 75967 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.

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 Labor cost Parts cost Cost per product Cost on U.S. operators 1 work-hour × $85 per hour = $85 .............................................................................................. $0 $85 $3,315 jbell on DSKJLSW7X2PROD with PROPOSALS 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 VerDate Sep<11>2014 17:37 Nov 25, 2020 Jkt 253001 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 PO 00000 Frm 00043 Fmt 4702 Sfmt 4702 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.

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:

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,

reference, Safety.

The Proposed Amendment

    Accordingly, under the authority delegated to me by the 
Administrator, the FAA proposes to amend 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 (AD):

Bombardier, Inc.: Docket No. FAA-2020-1034; Project Identifier MCAI-
2020-00951-T.

(a) Comments Due Date

    The FAA must receive comments by January 11, 2021.

(b) Affected ADs

    None.

(c) Applicability

    This AD applies to Bombardier, Inc., Model CL-600-2B16 (601-3A, 
601-3R, and 604 Variants), serial numbers 5301 through 5665 
inclusive, and 5701 through 5988 inclusive, certificated in any 
category.

(d) Subject

    Air Transport Association (ATA) of America Code 34, Navigation.

(e) Reason

    This AD was prompted by a determination that certain airplanes 
have outdated magnetic variation (MagVar) tables inside navigation 
systems. 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 (e.g., 
outdated MagVar tables can lead to significantly inaccurate heading, 
course, and bearing calculations).

(f) Compliance

    Comply with this AD within the compliance times specified, 
unless already done.

(g) Airplane Flight Manual (AFM) Revision

    Within 60 days after the effective date of this AD: Revise the 
existing AFM to incorporate the information specified in Section 02-
09, Navigation Systems Limitations, of Chapter 2--LIMITATIONS, of 
the applicable Bombardier Challenger AFM specified in figure 1 to 
paragraph (g) of this AD.

inspector, or lacking a principal inspector, the manager of the 
responsible Flight Standards Office.
    (2) Contacting the Manufacturer: For any requirement in this AD 
to obtain instructions from a manufacturer, the instructions must be
