SUPPLEMENTARY INFORMATION:
Background
The FAA issued a notice of proposed rulemaking (NPRM) to amend 14
CFR part 39 by adding an AD that would apply to all MHI RJ Aviation ULC
Model CL-600-2E25 (Regional Jet Series 1000) airplanes. The NPRM
published in the Federal Register on January 11, 2024 (89 FR 1849). The
NPRM was prompted by AD CF-2023-43, dated June 21, 2023, issued by
Transport Canada, which is the aviation authority for Canada (Transport
Canada AD CF-2023-43) (also referred to as the MCAI). The MCAI states
that new or more restrictive airworthiness limitations have been
developed.
In the NPRM, the FAA proposed to require revising the existing
maintenance or inspection program, as applicable, to incorporate new or
more restrictive airworthiness limitations, as specified in Transport
Canada AD CF-2023-43. The FAA is issuing this AD to prevent potential
fatigue cracking and damage in principal structural elements. The
unsafe condition, if not addressed, could result in reduced structural
integrity of the airplane.
You may examine the MCAI in the AD docket at <a href="http://regulations.gov">regulations.gov</a> under
Docket No. FAA-2024-0026.
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
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 this State of Design Authority, it
has notified the FAA of the unsafe condition described in the MCAI
referenced above. The FAA reviewed the relevant data and determined
that air safety requires adopting this AD as proposed. Accordingly, the
FAA is issuing this AD
[[Page 24690]]
to address the unsafe condition on this product. 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.
Related Service Information Under 1 CFR Part 51
The FAA reviewed Transport Canada AD CF-2023-43, which specifies
new or more restrictive airworthiness limitations for airplane
structures and a safe life limit. 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 5 airplanes of U.S.
registry. The FAA estimates the following costs to comply with this AD:
The FAA has determined that revising the existing maintenance or
inspection program takes an average of 90 work-hours per operator,
although the agency recognizes that this number may vary from operator
to operator. Since operators incorporate maintenance or inspection
program changes for their affected fleet(s), the FAA has determined
that a per-operator estimate is more accurate than a per-airplane
estimate. Therefore, the agency estimates the average total cost per
operator to be $7,650 (90 work-hours x $85 per work-hour).
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.

2. The FAA amends Sec. 39.13 by adding the following new airworthiness
directive:
2024-06-05 MHI RJ Aviation ULC (Type Certificate Previously Held by
Bombardier, Inc.): Amendment 39-22710; Docket No. FAA-2024-0026;
Project Identifier MCAI-2023-00776-T.

Series 1000) airplanes, certificated in any category.
(d) Subject
Air Transport Association (ATA) of America Code 05, Time Limits/
Maintenance Checks.
(e) Unsafe Condition
This AD was prompted by a determination that new or more
restrictive airworthiness limitations are necessary. The FAA is
issuing this AD to prevent potential fatigue cracking and damage in
principal structural elements. The unsafe condition, if not
addressed, could result in reduced structural integrity of the
airplane.
(f) Compliance
Comply with this AD within the compliance times specified,
unless already done.
(g) Requirements
Except as specified in paragraph (h) of this AD: Comply with all
required actions and compliance times specified in, and in

specifies to ``incorporate the new and revised tasks identified in
Table 1 below, in the appropriate chapter within Section 2 and
Section 3 of the MRM CSP B-053 Part 2 manual,'' this AD requires
replacing that text with ``revise the existing maintenance or
inspection program, as applicable, by incorporating the new and
revised tasks identified in Table 1.''
(3) The initial compliance time for doing the tasks specified in
paragraph 1. of Transport Canada AD CF-2023-43 is at the applicable
``thresholds'' and ``discard times'' as specified in the service
information referenced in paragraph 1. of Transport Canada AD CF-
2023-43, or within 60 days after the effective date of this AD,
whichever occurs later.
(4) This AD does not adopt paragraph 2. of Transport Canada AD
CF-2023-43.

revised as required by paragraph (g) of this AD, no alternative
actions (e.g., inspections) and intervals are allowed unless they
are approved as specified in the provisions of the ``Corrective
Actions'' section of Transport Canada AD CF-2023-43.
(j) Additional AD Provisions
The following provisions also apply to this AD:
(1) Alternative Methods of Compliance (AMOCs): The Manager,
