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 Model
CL-600-2C10 (Regional Jet Series 700, 701 & 702), CL-600-2C11 (Regional
Jet Series 550), CL-600-2D15 (Regional Jet Series 705), CL-600-2D24
(Regional Jet Series 900), and CL-600-2E25 (Regional Jet Series 1000)
airplanes. The NPRM published in the Federal Register on September 13,
2023 (88 FR 62709). The NPRM was prompted by AD CF-2023-10, dated
February 17, 2023, issued by Transport Canada, which is the aviation
authority for Canada (referred to after this as the MCAI). The MCAI
states that following maintenance on a Model CL-600-2C10 airplane, a Y-
belt (also known as lap belt) was re-installed in the wrong
orientation. The MCAI further states that the instructions contained
within the aircraft maintenance manual (AMM) on how to install the
passenger seat Y-belts, showed an incorrect orientation of the Y-belt
assembly. The MCAI confirms the manufacturer updated the AMM tasks and
these instructions have been corrected. Y-belts installed in the wrong
orientation, if not corrected, could result in passenger injury due to
head impact on the front monument during an emergency landing.
In the NPRM, the FAA proposed to require inspecting certain Y-belts
for correct installation and damage and corrective actions if
necessary. The FAA also proposed to prohibit the use of certain
revisions of a maintenance task. The FAA is issuing this AD to address
the unsafe condition on these products.
You may examine the MCAI in the AD docket at regulations.gov under
Docket No. FAA-2023-1823.

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 Service Bulletin 670BA-25-135, Revision B,
dated November 25, 2022. This service information specifies procedures
to inspect for correct installation (as shown in certain maintenance
tasks) of each passenger seat Y-belt. This service information also
specifies corrective actions, which include re-installing each
incorrectly installed Y-belt per certain maintenance tasks and
addressing damage (includes dents or misshapen hooks that attach the
belt to the seat).
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 606 airplanes of U.S.
registry. The FAA estimates the following costs to comply with this AD:


Estimated Costs for Required Actions

Labor cost
Parts cost
Cost per product
Cost on U.S. operators
2 work-hours x $85 per hour = $170
$0
$170
$103,020

The FAA estimates the following costs to do any necessary
replacements that would be required based on the results of the
inspection. The agency has no way of determining the number of aircraft
that might need these replacements.

Estimated Costs of On-Condition Actions

Labor cost
Parts cost
Cost per product
Up to 0.5 work-hours x $85 per hour = $43 Up to $550 per Y-belt assembly
Up to $593

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.
