Airworthiness Directives; Airbus Canada Limited Partnership (Type 
Certificate Previously Held by C Series Aircraft Limited Partnership 
(CSALP); Bombardier, Inc.) Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

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

SUMMARY: The FAA is adopting a new airworthiness directive (AD) for 
certain Airbus Canada Limited Partnership Model BD-500-1A10 and BD-500-
1A11 airplanes. This AD was prompted by a report that some tie-rod 
assemblies may have been overtightened during the installation of 
interior monuments (such as galleys, lavatories, and forward stowage or 
wardrobes). This AD requires adjusting the tie-rod assemblies, as 
specified in a Transport Canada Civil Aviation (TCCA) AD, which is 
incorporated by reference. The FAA is issuing this AD to address the 
unsafe condition on these products.

DATES: This AD is effective April 4, 2022.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in this AD as of April 4, 
2022.

ADDRESSES: For TCCA material incorporated by reference (IBR) in this 
AD, contact TCCA, Transport Canada National Aircraft Certification, 159

SUPPLEMENTARY INFORMATION:

Background

    The TCCA, which is the aviation authority for Canada, has issued 
TCCA AD CF-2021-25, dated July 22, 2021 (TCCA AD CF-2021-25) (also 
referred to as the MCAI), to correct an unsafe condition for certain 
Airbus Canada Limited Partnership Model BD-500-1A10 and BD-500-1A11 
airplanes.
    The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 
CFR part 39 by adding an AD that would apply to certain Airbus Canada 
Limited Partnership Model BD-500-1A10 and BD-500-1A11 airplanes. The 
NPRM published in the Federal Register on December 17, 2021 (86 FR 
71589). The NPRM was prompted by a report that some tie-rod assemblies 
may have been overtightened during the installation of interior 
monuments (such as galleys, lavatories, and forward stowage or 
wardrobes). The NPRM proposed to require adjusting the tie-rod 
assemblies, as specified in TCCA AD CF-2021-25.
    The FAA is issuing this AD to address overtightened (pre-loaded) 
tie-rods that induce unwanted stress in a monument and may cause the 
monument to become unconstrained in an emergency landing, potentially 
blocking exits or injuring occupants. See the MCAI for additional 
background information.

Discussion of Final Airworthiness Directive

Comments

    The FAA received no comments on the NPRM or on the determination of 
the cost to the public.

Conclusion

    The FAA reviewed the relevant data 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.

Related Service Information Under 1 CFR Part 51

    TCCA AD CF-2021-25 specifies procedures for, among other actions, 
adjustment of the affected tie-rod assemblies to remove any pre-load. 
This material 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.

Costs of Compliance

    The FAA estimates that this AD affects 21 airplanes of U.S. 
registry. The FAA estimates the following costs to comply with this 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

    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.
