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-600-2C10 (Regional Jet Series 700, 701 & 702), CL-600-2D15
(Regional Jet Series 705), and CL-600-2D24 (Regional Jet Series 900)
airplanes. The NPRM published in the Federal Register on May 29, 2024
(89 FR 46336). The NPRM was prompted by AD CF-2023-79, dated December
21, 2023, issued by Transport Canada, which is the aviation authority
for Canada (Transport Canada AD CF-2023-79) (also referred to as the
MCAI). The MCAI states that the electrical harnesses in the overhead
bin above the class divider may have insufficient or no separation with
the class divider mounting plate. This condition, if not corrected,
could result in the electrical harnesses becoming chafed, which could
affect the following aircraft systems: ordinance signs, emergency
lights/signs, passenger oxygen, and passenger address and air
conditioning systems.
In the NPRM, the FAA proposed to require inspecting the overhead
bin electrical harnesses at the class dividers and modifying the class
divider mounting plate assembly or accomplishing a temporary repair if
necessary; and, eventually modifying the class divider mounting plate
assembly if a modification was not done after accomplishing the
inspection, as specified in Transport Canada AD CF-2023-79. 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-2024-1470.
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.
Material Incorporated by Reference Under 1 CFR Part 51
Transport Canada AD CF-2023-79 specifies procedures for inspecting
the left-hand and right-hand overhead bin electrical harnesses at the
class divider for damage (e.g., chafing), and if damage is found,
modifying the class divider mounting plate assembly to improve the
[[Page 76400]]
overhead bin harnesses protection or accomplishing a temporary repair.
Transport Canada AD CF-2023-79 also specifies procedures for eventually
modifying the class divider mounting plate assembly if a modification
was not done after accomplishing the inspection (i.e., if a temporary
repair was done or if no damage was found after accomplishing the
inspection). 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 246 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
----------------------------------------------------------------------------------------------------------------
3 work-hours x $85 per hour = $255...... $0 $255...................... $62,730.
Up to 9 work-hours x $85 per hour = $765 $366 Up to $1,131.............. Up to $278,226.
----------------------------------------------------------------------------------------------------------------
The FAA estimates the following costs to do any necessary on-
condition actions that would be required based on the results of any
required actions. The FAA has no way of determining the number of
aircraft that might need these on-condition actions:
Estimated Costs of On-Condition Actions *
------------------------------------------------------------------------
Labor cost Parts cost Cost per product
------------------------------------------------------------------------
Up to 9 work-hours x $85 per hour $366 Up to $1,131.
= $765.
------------------------------------------------------------------------
* The FAA has received no definitive data on which to base the cost
estimates for the on-condition optional temporary repair 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.
List of Subjects in 14 CFR Part 39
