Abstract
The FAA is adopting a new airworthiness directive (AD) for certain Bombardier, Inc., Model CL-600-1A11 (600), CL-600-2A12 (601), and CL-600-2B16 (601-3A, 601-3R, and 604 Variants) airplanes. This AD was prompted by reports of some passenger oxygen mask dispensing units (MDUs) with lanyards that are too long to meet the proper length specifications of the airplane. This AD requires replacing the affected MDUs with units that meet the proper length specifications, replacing the placards, and re-identifying the assemblies. The FAA is issuing this AD to address the unsafe condition on these products.

AGENCY: Federal Aviation Administration (FAA), DOT.
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: The FAA is adopting a new airworthiness directive (AD) for
certain Bombardier, Inc., Model CL-600-1A11 (600), CL-600-2A12 (601),
and CL-600-2B16 (601-3A, 601-3R, and 604 Variants) airplanes. This AD
was prompted by reports of some passenger oxygen mask dispensing units
(MDUs) with lanyards that are too long to meet the proper length
specifications of the airplane. This AD requires replacing the affected
MDUs with units that meet the proper length specifications, replacing
the placards, and re-identifying the assemblies. The FAA is issuing
this AD to address the unsafe condition on these products.
DATES: This AD is effective May 18, 2023.
The Director of the Federal Register approved the incorporation by
reference of certain publications listed in this AD as of May 18, 2023.

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-600-1A11 (600), CL-600-2A12 (601), and CL-600-2B16 (601-
3A, 601-3R, and 604 Variants) airplanes. The NPRM published in the
Federal Register on December 27, 2022 (87 FR 79259). The NPRM was
prompted by AD CF-2022-50, dated August 25, 2022, issued by Transport
Canada, which is the aviation authority for Canada (referred to after
this as the MCAI). The MCAI states that lanyards of passenger mask
dispensing units installed in the affected airplanes are too long to
meet the proper length specifications of the aircraft. This condition,
if not corrected, could result in the inability to initiate the flow of
oxygen to the mask when required in an emergency situation, with no
indication to the passenger that they are not receiving oxygen.
In the NPRM, the FAA proposed to require replacing the affected
MDUs with units that meet the proper length specifications, replacing
the placards, and re-identifying the assemblies. 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-2022-1654.
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
[[Page 22363]]
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 following Bombardier service information, which
specifies procedures for identifying part numbers of the drop-down
oxygen boxes, performing drop-down oxygen mask reach testing, marking
failed seats as inoperative with placards, and replacing affected
oxygen masks:
<bullet> Service Bulletin 600-0777, dated December 13, 2021.
<bullet> Service Bulletin 601-1109, Revision 01, dated May 6, 2022.
<bullet> Service Bulletin 604-35-007, Revision 01, dated May 6,
2022.
These documents are distinct since they apply to different airplane
models. 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 301 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.
Labor cost Parts cost product operators
----------------------------------------------------------------------------------------------------------------
1 work-hour x $85 per hour = $85............................. $0 $85 $25,585
----------------------------------------------------------------------------------------------------------------
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
------------------------------------------------------------------------
Cost per
Labor cost Parts cost product
------------------------------------------------------------------------
2 work-hours x $85 per hour = $170.... $100 $270
------------------------------------------------------------------------
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.

dispensing units installed in the affected airplanes with lanyards
that are too long to meet the proper length specifications of the
airplane. The FAA is issuing this AD to address the inability to
initiate flow of oxygen to the mask. The unsafe condition, if not

this AD.
(1) If any drop-down oxygen box part number (P/N) installed on
the airplane matches any P/N listed in Table 1 of Section 2.B. of
the applicable service information: Before further flight, perform
drop-down oxygen mask reach testing in accordance with Section
2.B.(2) of the Accomplishment Instructions of the applicable service
information identified in paragraphs (c)(1) through (4) of this AD.

in paragraphs (c)(1) through (4) of this AD.
(2) If the part number of any drop-down oxygen box assembly
installed on the airplane is not found in Table 1 of Section 2.B. of
the applicable service information identified in paragraphs (c)(1)
