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

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.
This proposed AD was prompted by a report that some tie-rod
assemblies may have been over-tightened during the installation of
interior monuments (such as galleys, lavatories, and forward stowage or
wardrobes). The FAA is proposing this AD to address over-tightened
(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.
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.
FAA's Determination
These products have been approved by the aviation authority of
another country and are approved for operation in the United States.
Pursuant to the FAA's bilateral agreement with the State of Design
Authority, it has notified the FAA of the unsafe condition described in
the MCAI referenced above. The FAA is issuing this NPRM after
determining that the unsafe condition described previously is likely to
exist or develop in other products of these same type designs.
Proposed AD Requirements in This NPRM
This proposed AD would require accomplishing the actions specified
in TCCA AD CF-2021-25 described previously, except for any differences
identified as exceptions in the regulatory text of this proposed AD and
except as discussed under ``Difference Between this Proposed AD and the
MCAI.''
Explanation of Required Compliance Information
In the FAA's ongoing efforts to improve the efficiency of the AD
process, the FAA developed a process to use some civil aviation
authority (CAA) ADs as the primary source of information for compliance
with requirements for corresponding FAA ADs. The FAA has been
coordinating this process with manufacturers and CAAs. As a result, the
FAA proposes to incorporate TCCA AD CF-2021-25 by reference in the FAA
final rule. This proposed AD would, therefore, require compliance with
TCCA AD CF-2021-25 in its entirety through that incorporation, except
for any differences identified as exceptions in the regulatory text of
this proposed AD. Service information required by TCCA AD CF-2021-25
for compliance will be available at <a href="https://www.regulations.gov">https://www.regulations.gov</a> by
searching for and locating Docket No. FAA-2021-1067 after the FAA final
rule is published.
Difference Between This Proposed AD and the MCAI
TCCA AD CF-2021-25 specifies an inspection of the tie-rod for pre-
load. The service information required by TCCA AD CF-2021-25 specifies
that it ``gives the procedure to inspect and release the load the tie-
rod assemblies,'' but does not include any specific inspection
procedures. This proposed AD does not propose to include any
inspection.
Costs of Compliance
The FAA estimates that this proposed AD would affect 21 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.
