Background Transport Canada, which is the aviation authority for Canada, has issued Transport Canada AD CF–2023– 21, dated March 30, 2023 (Transport Canada AD CF–2023–21) (also referred to after this as the MCAI), to correct an unsafe condition on certain Bombardier, Inc., Model CL–600–2B16 (604 Variant) airplanes. The MCAI states that some airplanes were delivered without a portable PBE device located in the forward left side cabin area of the airplane. The portable PBE device is required to meet the certification standards of Transport Canada and the FAA 1 and provides protection for crew members when investigating or combatting a fire in the cabin. The FAA is proposing this AD to address the unsafe condition on these products. You may examine the MCAI in the AD docket at regulations.gov under Docket No. FAA–2023–1715. 1 14 E:\FR\FM\24AUP1.SGM CFR 25.1439. 24AUP1 Federal Register / Vol. 88, No. 163 / Thursday, August 24, 2023 / Proposed Rules 57903 Related Service Information Under 1 CFR Part 51 course of business or by the means identified in the ADDRESSES section. on other products of the same type design. The FAA reviewed Bombardier Service Bulletin 604–35–008, Revision 02, dated January 13, 2023. This service information specifies procedures for performing a general visual inspection of the forward left side cabin area of the airplane for a portable PBE device and, if missing, installing a portable PBE device and its associated placard. This service information is reasonably available because the interested parties have access to it through their normal 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 service information referenced above. The FAA is issuing this NPRM after determining that the unsafe condition described previously is likely to exist or develop Proposed AD Requirements in This NPRM This proposed AD would require accomplishing the actions specified in the service information already described. Costs of Compliance The FAA estimates that this AD, if adopted as proposed, would affect 139 airplanes of U.S. registry. The FAA estimates the following costs to comply with this proposed AD: ESTIMATED COSTS FOR REQUIRED ACTIONS Labor cost Parts cost Cost per product Cost on U.S. operators 0.5 work-hour × $85 per hour = $43 ........................................................................................... $0 $43 $5,977 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 Labor cost Parts cost Cost per product 2 work-hours × $85 per hour = $170 .... $2,157 $2,327 lotter on DSK11XQN23PROD with PROPOSALS1 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. VerDate Sep<11>2014 15:52 Aug 23, 2023 Jkt 259001 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. 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.

Background

    Transport Canada, which is the aviation authority for Canada, has 
issued Transport Canada AD CF-2023-21, dated March 30, 2023 (Transport 
Canada AD CF-2023-21) (also referred to after this as the MCAI), to 
correct an unsafe condition on certain Bombardier, Inc., Model CL-600-
2B16 (604 Variant) airplanes. The MCAI states that some airplanes were 
delivered without a portable PBE device located in the forward left 
side cabin area of the airplane. The portable PBE device is required to 
meet the certification standards of Transport Canada and the FAA \1\ 
and provides protection for crew members when investigating or 
combatting a fire in the cabin.

Related Service Information Under 1 CFR Part 51

    The FAA reviewed Bombardier Service Bulletin 604-35-008, Revision 
02, dated January 13, 2023. This service information specifies 
procedures for performing a general visual inspection of the forward 
left side cabin area of the airplane for a portable PBE device and, if 
missing, installing a portable PBE device and its associated placard. 
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.

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 service information 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 require accomplishing the actions specified 
in the service information already described.

Costs of Compliance

    The FAA estimates that this AD, if adopted as proposed, would 
affect 139 airplanes of U.S. registry. The FAA estimates the following 
costs to comply with this proposed AD:

                                      Estimated Costs for Required Actions

----------------------------------------------------------------------------------------------------------------

    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

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.
