Airworthiness Directives; MHI RJ Aviation ULC (Type Certificate 
Previously Held by 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 certain MHI RJ Aviation ULC Model CL-600-2B19 (Regional Jet Series 
100 & 440) airplanes; Model CL-600-2C10 (Regional Jet Series 700, 701 & 
702) airplanes; Model CL-600-2C11 (Regional Jet Series 550) airplanes; 
Model CL-600-2D15 (Regional Jet Series 705) airplanes; Model CL-600-
2D24 (Regional Jet Series 900) airplanes; and Model CL-600-2E25 
(Regional Jet Series 1000) airplanes. This proposed AD was prompted by 
reports of displayed headings changing from MAG to TRU with no pilot 
action, which may result in misleading heading information on both 
primary function displays (PFDs) and multi-function displays (MFDs), 
and misleading course information on flight management systems (FMS). 
This proposed AD would require amending the existing airplane flight 
manual (AFM) to provide the flightcrew with updated procedures for 
accurate heading and course information. 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 16, 
2022.

SUPPLEMENTARY INFORMATION:

Comments Invited

    The FAA invites you to send any written relevant data, views, or 
arguments about this proposal. Send your comments to an address listed 
under ADDRESSES. Include ``Docket No. FAA-2022-0155; Project Identifier 
MCAI-2021-00585-T'' at the beginning of your comments. The most helpful 
comments reference a specific portion of the proposal, explain the 
reason for any recommended change, and include supporting data. The FAA 
will consider all comments received by the closing date and may amend 
the proposal because of those comments.
    Except for Confidential Business Information (CBI) as described in 
the following paragraph, and other information as described in 14 CFR 
11.35, the FAA will post all comments received, without change, to 
https://www.regulations.gov, including any personal information you 
provide. The agency will also post a report summarizing each 
substantive verbal contact received about this NPRM.

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, 
Westbury, NY 11590; telephone 516-228-7300; email [email protected]. Any commentary that the FAA receives which is not 
specifically designated as CBI will be placed in the public docket for 
this rulemaking.

Background

    Transport Canada Civil Aviation (TCCA), which is the aviation 
authority for Canada, has issued TCCA AD CF-2021-19, issued May 13, 
2021 (TCCA AD CF-2021-19) (also referred to after this as the Mandatory 
Continuing Airworthiness Information, or the MCAI), to correct an 
unsafe condition for certain MHI RJ Aviation ULC Model CL-600-2B19 
(Regional Jet Series 100 & 440) airplanes; Model CL-600-2C10 (Regional 
Jet Series 700, 701 & 702) airplanes; Model CL-600-2C11 (Regional Jet 
Series 550) airplanes; Model CL-600-2D15 (Regional Jet Series 705) 
airplanes; Model CL-600-2D24 (Regional Jet Series 900) airplanes; and 
Model CL-600-2E25 (Regional Jet Series 1000) airplanes. You may examine 
the MCAI in the AD docket at https://www.regulations.gov by searching 
for and locating Docket No. FAA-2022-0155.
    This proposed AD was prompted by reports of displayed headings 
changing from MAG to TRU with no pilot action, which may result in 
misleading heading information on both PFDs and MFDs, and misleading 
course information on FMS. This misleading information may occur on 
airplanes with certain inertial reference systems (IRSs); the IRS is 
part of the navigation system and provides data on the airplane's 
position. The FAA is proposing this AD to prevent operation outside the 
terrain and obstacle protection provided in instrument procedure and 
route designs, which could result in reduced operational safety 
margins. See the MCAI for additional background information.

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 AD Requirements in This NPRM

    This proposed AD would require accomplishing the actions specified 
in the service information already described.
    TCCA AD CF-2021-19 requires operators to ``advise all flight 
crews'' of revisions to the AFM, and thereafter to ``operate the 
aircraft accordingly.'' However, this proposed AD would not 
specifically require those actions as those actions are already 
required by FAA regulations. FAA regulations require operators furnish 
to pilots any changes to the AFM (for example, 14 CFR 121.137), and to 
ensure the pilots are familiar with the AFM (for example, 14 CFR 
91.505). As with any other flightcrew training requirement, training on 
the updated AFM content is tracked by the operators and recorded in 
each pilot's training record, which is available for the FAA to review. 
FAA regulations also require pilots to follow the procedures in the 
existing AFM including all updates. 14 CFR 91.9 requires that any 
person operating a civil aircraft must comply with the operating 
limitations specified in the AFM. Therefore, including a requirement in 
this proposed AD to operate the airplane according to the revised AFM 
would be redundant and unnecessary.

Costs of Compliance

    The FAA estimates that this AD, if adopted as proposed, would 
affect 1,113 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) 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.

reference, Safety.
