14 CFR Part 39

[Docket No. FAA-2022-0155; Project Identifier MCAI-2021-00585-T;

Airworthiness Directives; MHI RJ Aviation ULC (Type Certificate 
Previously Held by Bombardier, Inc.) Airplanes

AGENCY: Federal Aviation Administration (FAA), Department of 
Transportation (DOT).

ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: The FAA is adopting 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 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 (FMSs). This 
AD requires amending the existing airplane flight manual (AFM) to 
provide the flightcrew with updated procedures for accurate heading and 
course information. The FAA is issuing this AD to address the unsafe 
condition on these products.

DATES: This AD is effective November 3, 2022.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in this AD as of November 3, 
2022.

SUPPLEMENTARY INFORMATION:

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 regulations.gov by searching for and 
locating Docket No. FAA-2022-0155.
    The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 
CFR part 39 by adding an AD that would apply to 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. The NPRM

[[Page 58951]]

published in the Federal Register on April 1, 2022 (87 FR 19026). The 
NPRM 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 
FMSs. The NPRM proposed to require amending the existing AFM to provide 
the flightcrew with updated procedures for accurate heading and course 
information. The FAA is issuing 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.

Discussion of Final Airworthiness Directive

Comments

    The FAA received a comment from the Air Line Pilots Association, 
International (ALPA) who supported the NPRM without change.

Conclusion

    The FAA reviewed the relevant data, considered the comment 
received, and determined that air safety requires adopting this AD as 
proposed. Except for minor editorial changes, this AD is adopted as 
proposed in the NPRM. None of the changes will increase the economic 
burden on any operator. Accordingly, the FAA is issuing this AD to 
address the unsafe condition on these products.

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.
