Abstract
The FAA is adopting a new airworthiness directive (AD) for certain MHI RJ Aviation ULC Model CL-600-2D24 (Regional Jet Series 900) airplanes. This AD was prompted by a report of a manufacturing error that can create dents on the lower wing plank, close to the flap arm locations at certain wing stations; as a result, cracks could develop and weaken the structural integrity of the wings before being detected by any existing required inspections. This AD requires an inspection for damage (including dents, cracks, discoloration, gouges, scratches, or other surface damage) of the lower wing plank in the flap arm areas at certain wing stations, and repair if necessary. The FAA is issuing this AD to address the unsafe condition on these products.

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 certain MHI RJ Aviation
ULC Model CL-600-2D24 (Regional Jet Series 900) airplanes. The NPRM
published in the Federal Register on June 2, 2022 (87 FR 33454). The
NPRM was prompted by AD CF-2021-31, dated September 14, 2021, issued by
Transport Canada Civil Aviation (TCCA), which is the aviation authority
for Canada (referred to after this as the MCAI). The MCAI states that a
manufacturing error may have resulted in dents on the lower wing plank,
close to the five flap arm locations at wing station (WS) 54.55, WS
128.00, WS 179.00, WS 220.00, and WS 264.00. These dents could lead to
cracks that could weaken the structural integrity of the wings before
being detected by any existing required inspection.
In the NPRM, the FAA proposed to require an inspection for damage
(including dents, cracks, discoloration, gouges, scratches, or other
surface damage) of the lower wing plank in the flap arm areas at
certain wing stations, and repair if necessary. The FAA is issuing this
AD to address the unsafe condition on these products.
You may examine the MCAI in the AD docket at <a href="http://regulations.gov">regulations.gov</a> under
Docket No. FAA-2022-0592.
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 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 MHI RJ Aviation Service Bulletin 670BA-57-029,
dated February 2, 2021. This service information specifies procedures
for, among other actions, doing a detailed visual inspection for damage
(including dents, cracks, discoloration, gouges, scratches, or other
surface damage) of the outer aft lower skin at WS 54.55, WS 128.00, WS
179.00, WS 220.00, and WS 264.00, and repair. This service information
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 14 airplanes of U.S.
registry. The FAA estimates the following costs to comply with this AD:
[[Page 54354]]
Estimated Costs for Required Actions
----------------------------------------------------------------------------------------------------------------
Cost per Cost on U.S.
Labor cost Parts cost product operators
----------------------------------------------------------------------------------------------------------------
2 work-hours x $85 per hour = $170........................... $0 $170 $2,380
----------------------------------------------------------------------------------------------------------------
The FAA has received no definitive data on which to base the cost
estimates for the on-condition actions specified in 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.

1. The authority citation for part 39 continues to read as follows:
Authority: 49 U.S.C. 106(g), 40113, 44701.
Sec. 39.13 [Amended]
0
2. The FAA amends Sec. 39.13 by adding the following new airworthiness
directive:
2022-18-17 MHI RJ Aviation ULC (Type Certificate Previously Held by
Bombardier, Inc.): Amendment 39-22168; Docket No. FAA-2022-0592;
Project Identifier MCAI-2021-01023-T.
(a) Effective Date
This airworthiness directive (AD) is effective October 11, 2022.
(b) Affected ADs
None.
(c) Applicability
This AD applies to MHI RJ Aviation ULC (type certificate
previously held by Bombardier, Inc.) Model CL-600-2D24 (Regional Jet
