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 Bombardier,
Inc., Model CL-600-2B16 (604 Variant) airplanes. The NPRM published in
the Federal Register on July 25, 2023 (88 FR 47827). The NPRM was
prompted by AD CF-2023-06, dated February 9, 2023 (referred to after
this as the MCAI), issued by Transport Canada, which is the aviation
authority for Canada. The MCAI states the sleeve loops on certain
passenger oxygen mask lanyards were found to have improper crimping and
unsealed ends.
In the NPRM, the FAA proposed to require an inspection of the
passenger oxygen mask lanyards and replacement of defective oxygen mask
lanyards. In the NPRM, the FAA also proposed to prohibit the
installation of affected parts. The FAA is issuing this AD to address
these defective oxygen mask lanyards, which could result in no oxygen
flow to the mask during an emergency.
You may examine the MCAI in the AD docket at <a href="http://regulations.gov">regulations.gov</a> under
Docket No. FAA-2023-1505.
Discussion of Final Airworthiness Directive
Comments
The FAA received a comment from Bombardier. The following presents
the comment received on the NPRM and the FAA's response to the comment.
Request for Removal of Certain Variants
Bombardier requested that the proposed AD be revised to remove
reference to 601-3A and 601-3R Variants. The commenter stated that the
proposed AD only applies to Model CL-600-2B16 (604 Variant) airplanes
(Challenger 605 designation). Bombardier noted that the airplane serial
numbers given in Bombardier Service Bulletin 605-35-008, dated October
28, 2022, and referenced in Transport Canada AD CF-2023-06, are all
Model CL-600-2B16 (604 Variant) airplanes.
The FAA agrees for the reasons provided. The FAA revised the
Summary, Background, and paragraph (c) of this AD accordingly.
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, considered the
comments received, 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, and any other changes described previously, 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 Bombardier Service Bulletin 605-35-008, dated
October 28, 2022. This service information specifies procedures for a
visual inspection of the existing passenger oxygen mask lanyards
installed in the cabin or lavatory oxygen box assemblies, and
replacement of the defective oxygen mask lanyards. The
[[Page 87335]]
defective oxygen mask lanyards had improperly crimped sleeve loops and
unsealed ends.
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 120 airplanes of U.S.
registry. The FAA estimates the following costs to comply with this AD:
Estimated Costs for Required Actions
----------------------------------------------------------------------------------------------------------------
Cost per Cost on U.S.
Action Labor cost Parts cost product operators
----------------------------------------------------------------------------------------------------------------
Inspection............................ 1 work-hour x $85 per $0 $85 $10,200
hour = $85.
----------------------------------------------------------------------------------------------------------------
The FAA estimates the following costs to do any necessary on-
condition action 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 this on-condition action:
Estimated Costs of On-Condition Actions
----------------------------------------------------------------------------------------------------------------
Cost per
Action Labor cost Parts cost product
----------------------------------------------------------------------------------------------------------------
Replacement................................ 2 work-hours x $85 per hour = $170. $1,149 $1,319
----------------------------------------------------------------------------------------------------------------
The FAA has included all known costs in its cost estimate.
According to the manufacturer, however, some or all costs of this AD
may be covered under warranty, thereby reducing the cost impact on
affected operators.
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.
