Any commentary that the FAA receives which is not specifically designated as CBI will be placed in the public docket for this rulemaking. khammond on DSK9W7S144PROD with PROPOSALS 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, VerDate Sep<11>2014 17:13 Dec 30, 2024 Jkt 265001 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 Actions Since AD 2020–19–13 Was Issued Since the FAA issued AD 2020–19– 13, Transport Canada superseded AD CF–2019–26, dated July 19, 2019, and issued Transport Canada AD CF–2024– 09, dated March 14, 2024 (Transport Canada AD CF–2024–09) (referred to after this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; PO 00000 Frm 00027 Fmt 4702 Sfmt 4702 • 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. E:\FR\FM\31DEP1.SGM 31DEP1 Federal Register / Vol. 89, No. 250 / Tuesday, December 31, 2024 / Proposed Rules 107071 ESTIMATED COSTS FOR REQUIRED ACTIONS Labor cost Parts cost Cost per product Cost on U.S. operators 3 work-hours × $85 per hour = $255 ...................................................................................................... $1,530 $1,785 $342,720 Authority for This Rulemaking List of Subjects in 14 CFR Part 39 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. Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety. 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. The Proposed Amendment Accordingly, under the authority delegated to me by the Administrator, the FAA proposes to amend 14 CFR part 39 as follows: PART 39—AIRWORTHINESS DIRECTIVES 1. The authority citation for part 39 continues to read as follows: ■ Authority: 49 U.S.C. 106(g), 40113, 44701. § 39.13 [Amended] 2. The FAA amends § 39.13 by: a. Removing Airworthiness Directive (AD) 2020–19–13, Amendment 39– 21256 (85 FR 60887, September 29, 2020); and ■ b. Adding the following new AD: ■ ■ Bombardier, Inc.: Docket No. FAA–2024– 2717; Project Identifier MCAI–2024–00147– T. (a) Comments Due Date The FAA must receive comments on this airworthiness directive (AD) by February 14, 2025. (b) Affected ADs This AD replaces AD 2020–19–13, Amendment 39–21256 (85 FR 60887, September 29, 2020) (AD 2020–19–13). (c) Applicability This AD applies to Bombardier, Inc., airplanes, identified in paragraphs (c)(1) through (3), certificated in any category, equipped with Scott (Avox/Zodiac) 5500 or 5600 series 11 cubic foot portable oxygen bottle(s) with upper bracket part number (P/ N) 36758–02, P/N 36758–12 or P/N H3– 2091–1 installed at the neck of the bottle(s).

(3) Model CL–600–2B16 (601–3A, 601–3R, and 604 Variants) airplanes, serial numbers 5001 through 5194 inclusive, 5301 through 5665 inclusive, 5701 through 5988 inclusive, 6050 through 6119 inclusive, 6158, 6161, 6176, and 6181. (d) Subject Air Transport Association (ATA) of America Code 35, Oxygen. (e) Unsafe Condition This AD was prompted by a report indicating that the portable oxygen bottle installation’s upper bracket latch assembly can catch on the pressure gauge tube or on the pressure gauge bezel of the portable oxygen bottle. This AD was also prompted by the determination that four additional Model CL–600–2B16 airplanes may be subject to the unsafe condition. The FAA is issuing this AD to address the unsafe condition, which, if not addressed, could prevent fast and easy access to the portable oxygen bottle in an emergency situation. (f) Compliance Comply with this AD within the compliance times specified, unless already done.

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.

Confidential Business Information

    CBI is commercial or financial information that is both customarily 
and actually treated as private by its owner. Under the Freedom of 
Information Act (FOIA) (5 U.S.C. 552), CBI is exempt from public 
disclosure. If your comments responsive to this NPRM contain commercial 
or financial information that is customarily treated as private, that 
you actually treat as private, and that is relevant or responsive to 
this NPRM, it is important that you clearly designate the submitted 
comments as CBI. Please mark each page of your submission containing 
CBI as ``PROPIN.'' The FAA will treat such marked submissions as 
confidential under the FOIA, and they will not be placed in the public 
docket of this NPRM. Submissions containing CBI should be sent to 
Brenda Buitrago, Aviation Safety Engineer, FAA, 1600 Stewart Avenue, 
Suite 410, Westbury, NY 11590; telephone 516-228-7300; email [email protected]. Any commentary that the FAA receives which is not 
specifically designated as CBI will be placed in the public docket for 
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.

List of Subjects in 14 CFR Part 39

    Air transportation, Aircraft, Aviation safety, Incorporation by 
reference, Safety.
