PROPOSED AD BOMBARDIER, INC.: Docket No. FAA-2020-0206; Product Identifier 2019-NM-202-AD.
(a) COMMENTS DUE DATE

    The FAA must receive comments by May 11, 2020.

(b) AFFECTED ADS

    None.

(c) APPLICABILITY

    This AD applies to  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, certificated  in any category,
    all serial numbers.

(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    outdated magnetic variation (MV) tables inside navigation systems. 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    FAA is issuing this AD to address outdated MV tables inside navigation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    flight  route  designs   (e.g.,  outdated  MV   tables  can  lead   to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).

(f) COMPLIANCE

    Comply with this AD within the compliance times specified,  unless al-
    ready done.

(g) AIRPLANE FLIGHT MANUAL (AFM) REVISION

    Within 30 days after the effective date of this AD,  revise the exist-
    ing AFM to incorporate  the information specified  in  Section 02-09 -
    Navigation  System  Limitations,  of  Chapter 2 - LIMITATIONS,  of the
    applicable Bombardier CRJ Series Regional Jet AFM specified  in figure
    1 to paragraph (g) of this AD.

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 all 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. This proposed AD was prompted by a
determination that certain airplanes have outdated magnetic variation
(MV) tables inside navigation systems. This proposed AD would require
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 proposing
this AD to address the unsafe condition on these products.

DATES: The FAA must receive comments on this proposed AD by May 11, 2020.

ADDRESSES: You may send comments, using the procedures found in 14 CFR
11.43 and 11.45, by any of the following methods:

Discussion

Transport Canada Civil Aviation (TCCA), which is the aviation
authority for Canada, has issued Canadian AD CF-2019-40, dated November
1, 2019 (referred to after this as the Mandatory Continuing
Airworthiness Information, or "the MCAI"), to correct an unsafe
condition for all 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.

This proposed AD was prompted by a determination that certain
airplanes have outdated MV tables inside navigation systems. The FAA is
proposing 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.

Related Service Information Under 1 CFR Part 51

The FAA reviewed the following service information, which describes
procedures for updating, among other systems, the FMS, IRS, and AHRS.
These documents are distinct since they apply to different airplane
models.

Section 02-09 - Navigation System Limitations, of Chapter
2 - LIMITATIONS, of the Bombardier CRJ Series Regional Jet Model CL-600-
2B19 Airplane Flight Manual, CSP A-012, Volume 1, Revision 71A, dated
April 26, 2019.

Section 02-09 - Navigation System Limitations, of Chapter

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 a 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 agency 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, IRS, and AHRS limitations.

Costs of Compliance

The FAA estimates that this proposed AD affects 1,072 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 x $85 per hour = $85
$0
$85
$91,120

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.

List of Subjects in 14 CFR Part 39

Air transportation, Aircraft, Aviation safety, Incorporation by
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


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]

2. The FAA amends Sec. 39.13 by adding the following new airworthiness
directive (AD):
