RIN 2120-AA64
Airworthiness Directives; Bombardier, Inc., Airplanes
AGENCY: Federal Aviation Administration (FAA), DOT.
ACTION: Notice of proposed rulemaking (NPRM).
-----------------------------------------------------------------------
SUMMARY: The FAA proposes to supersede Airworthiness Directive (AD)
2020-19-13, which applies 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. AD 2020-19-13 requires a check to identify the
manufacturer and part number of the portable oxygen bottle
installation, and if necessary, modification of the portable oxygen
bottle installation. Since the FAA issued AD 2020-19-13, it was
determined that four additional airplanes are subject to the unsafe
condition. This proposed AD would continue to require the actions
specified in AD 2020-19-13 and would expand the applicability. The FAA
is proposing this AD to address the unsafe condition on these products.

this rulemaking.
Background
The FAA issued AD 2020-19-13, Amendment 39-21256 (85 FR 60887,
dated September 29, 2020) (AD 2020-19-13), 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. AD 2020-19-13 was prompted by
MCAI originated by Transport Canada, which is the aviation authority
for Canada. Transport Canada issued AD CF-2019-26, dated July 9, 2019
(Transport Canada AD CF-2019-26), to correct an unsafe condition.
AD 2020-19-13 requires a check to identify the manufacturer and
part number of the portable oxygen bottle installation, and, if
necessary, modification of the portable oxygen bottle installation. The
FAA issued AD 2020-19-13 to address the portable oxygen bottle
installation's upper bracket latch assembly catching on the pressure
gauge bezel of the portable oxygen bottle, which could prevent fast and
easy access to the portable oxygen bottle in an emergency situation.
Actions Since AD 2020-19-13 Was Issued
Since the FAA issued AD 2020-19-13, Transport Canada superseded AD
CF-2019-26, dated July 19, 2019, and issued Transport Canada AD CF-
2024-09, dated March 14, 2024 (Transport Canada AD CF-2024-09)
(referred to after this as the MCAI) to correct an unsafe condition on
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 MCAI
states four Model CL-600-2B16 airplanes have been added to the
applicability.
This proposed AD would add airplanes to the applicability. The FAA
is proposing this AD to address the portable oxygen bottle
installation's upper bracket latch assembly catching on the pressure
gauge tube or on the pressure gauge bezel of the portable oxygen
bottle, which, if not detected and corrected, could prevent fast and
easy access to the portable oxygen bottle in an emergency situation.
You may examine the MCAI in the AD docket at regulations.gov under
Docket No. FAA-2024-2717.
Related Material Under 1 CFR Part 51
The FAA reviewed the following material:
Bombardier Service Bulletin 600-0772, Revision 01, dated
June 28, 2023;
Bombardier Service Bulletin 601-0646, Revision 01, dated
June 28, 2023;
Bombardier Service Bulletin 604-35-006, Revision 01, dated
June 28, 2023;
Bombardier Service Bulletin 605-35-005, Revision 01, dated
June 28, 2023; and
Bombardier Service Bulletin 650-35-001, Revision 01, dated
June 28, 2023.
This material specifies procedures for a check to identify the
manufacturer and part number of the portable oxygen bottle
installation, and, if necessary, modification of the portable oxygen
bottle installation. These documents are distinct since they apply to
different airplane models/configurations.
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.
FAA's Determination
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 and
material referenced above. The FAA is issuing this NPRM after
determining that the unsafe condition described previously is likely to
exist or develop on other products of the same type design.
Proposed AD Requirements in This NPRM
This proposed AD would retain all requirements of AD 2020-19-13.
This proposed AD would add airplanes to the applicability. This
proposed AD would also require accomplishing the actions specified in
the material described previously.
Clarification of Compliance Time
Paragraph (h) of AD 2020-19-13 does not include a compliance time
for the modification. However, as specified in paragraph (g) of AD
2020-19-13 and this proposed AD, operators have 60 months to determine
if there is any affected part, and paragraph (h) of the proposed AD
provides the on-condition action (modification) if an affected part is
found. Therefore, the replacement in paragraph (h) of this AD, if
applicable, must also be done within 60 months.
Costs of Compliance
The FAA estimates that this AD, if adopted as proposed, would
affect 192 airplanes of U.S. registry.

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
The FAA determined that this proposed AD would not have federalism
implications under Executive Order 13132. This proposed AD would 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 this proposed
regulation:
(1) Is not a ``significant regulatory action'' under Executive
Order 12866,
(2) Would not affect intrastate aviation in Alaska, and
(3) Would not have a significant economic impact, positive or
negative, on a substantial number of small entities under the criteria
of the Regulatory Flexibility Act.
