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 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determination that certain airplanes have outdated magnetic variation 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airplanes have outdated MV tables inside navigation systems.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proposing this AD to address outdated MV tables inside navigation 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.

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:

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

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-2020-0206; 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

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 already done.

(g) Airplane Flight Manual (AFM) Revision

    Within 30 days after the effective date of this AD, revise the 
existing AFM to

[[Page 17038]]

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.

using any approved AMOC, notify your appropriate principal 
inspector, or lacking a principal inspector, the manager of the 
local flight standards district office/certificate holding district 
office.
    (2) Contacting the Manufacturer: For any requirement in this AD 
to obtain instructions from a manufacturer, the instructions must be 
accomplished using a method approved by the Manager, New York ACO 
Branch, FAA; or Transport Canada Civil Aviation (TCCA); or
