By decreasing the assessment rate by $0.02, assessment income would be approximately $120,000 ($0.03 multiplied by 4 million cartons). This amount, along with interest income, and funds from the authorized reserve, should provide sufficient funds to meet 2022–23 anticipated expenses. Prior to arriving at this budget and assessment rate, the Committee considered maintaining the current assessment rate of $0.05. However, leaving the assessment unchanged would generate excess revenue over the Committee’s budgeted expenses for the 2022–23 and potentially cause reserve amounts to surpass the limits specified by the Order. Consequently, the Committee determined the assessment rate should be decreased to $0.03 per 7/10-bushel carton and the alternative rejected. A review of historical information and preliminary information pertaining to the upcoming season indicates that the producer price for the 2022–23 season should be approximately $12.85 per 7/10-bushel carton or equivalent of oranges and grapefruit. The proposed assessment rate of $0.03 per 7/10-bushel carton or equivalent of oranges and grapefruit represents 0.23 percent of the $12.85 revenue for the 2022–23 fiscal period as a percentage of total producer revenue ($0.03 divided by $12.85 multiplied by 100). This proposed rule would decrease the assessment obligation imposed on handlers. Assessments are applied uniformly on all handlers, and some of the costs may be passed on to producers. However, decreasing the assessment rate reduces the burden on handlers and may also reduce the burden on producers. The Committee’s meeting was widely publicized throughout the Texas citrus industry and all interested persons were invited to attend the meeting and participate in Committee deliberations on all issues. Like all Committee meetings, the May 24, 2022, meeting was a public meeting and all entities, both large and small, were able to express views on this issue. Finally, interested persons are invited to submit comments on this proposed rule, including the regulatory and informational impacts of this action on small businesses. In accordance with the Paperwork Reduction Act of 1995 (44 U.S.C. Chapter 35), the Order’s information collection requirements have been previously approved by OMB and VerDate Sep<11>2014 16:19 Nov 17, 2022 Jkt 259001 assigned OMB No. 0581–0189 Fruit Crops. No changes in those requirements would be necessary as a result of this proposed rule. Should any changes become necessary, they would be submitted to OMB for approval. This proposed rule would not impose any additional reporting or recordkeeping requirements on either small or large Texas oranges and grapefruit handlers. As with all Federal marketing order programs, reports and forms are periodically reviewed to reduce information requirements and duplication by industry and public sector agencies. AMS is committed to complying with the E-Government Act, to promote the use of the internet and other information technologies to provide increased opportunities for citizen access to Government information and services, and for other purposes. AMS has not identified any relevant Federal rules that duplicate, overlap, or conflict with this proposed rule.

Background Transport Canada Civil Aviation (TCCA), which is the aviation authority for Canada, has issued TCCA AD CF– 2022–16R1, dated July 5, 2022 (TCCA AD CF–2022–16R1) (also referred to after this as the MCAI), to correct an unsafe condition on Model CL–600– 2B19 (Regional Jet Series 100 & 440), CL–600–2C10 (Regional Jet Series 700, 701 & 702), CL–600–2C11 (Regional Jet Series 550), CL–600–2D15 (Regional Jet Series 705), CL–600–2D24 (Regional Jet Series 900), and CL–600–2E25 (Regional Jet Series 1000) airplanes. The MCAI states that MHI RJ Aviation ULC received reports from the supplier of the overheat detection sensing elements of a manufacturing quality escape. Some of the sensing elements of the bleed air leak detection system were manufactured with insufficient salt fill, which can result in an inability to detect hot bleed air leaks and cause damage to surrounding structures and systems that can prevent continued safe flight and landing. You may examine the MCAI in the AD docket at regulations.gov under Docket No. FAA–2022–1474. PO 00000 Frm 00004 Fmt 4702 Sfmt 4702 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 described 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. This proposed AD would also prohibit the installation of affected parts. Costs of Compliance The FAA estimates that this AD, if adopted as proposed, would affect 1,126 airplanes of U.S. registry. The FAA estimates the following costs to comply with this proposed AD: E:\FR\FM\18NOP1.SGM 18NOP1 69212 Federal Register / Vol. 87, No. 222 / Friday, November 18, 2022 / Proposed Rules ESTIMATED COSTS FOR REQUIRED ACTIONS Model Labor cost Model CL–600–2B19 (526 airplanes) ..................................... 29 work hours × $85 per hour = $2,465. 82 work hours × $85 per hour = $6,970.

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. 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.

Airworthiness Directives; MHI RJ Aviation ULC (Type Certificate 
Previously Held by Bombardier, Inc.) Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: The FAA proposes to adopt a new airworthiness directive (AD) 
for certain MHI RJ Aviation ULC Model CL-600-2B19 (Regional Jet Series 
100 & 440), CL-600-2C10 (Regional Jet Series 700, 701 & 702), CL-600-
2C11 (Regional Jet Series 550), CL-600-2D15 (Regional Jet Series 705), 
CL-600-2D24 (Regional Jet Series 900), and CL-600-2E25 (Regional Jet 
Series 1000) airplanes. This proposed AD was prompted by reports from 
the supplier that sensing elements of the bleed air leak detection 
system were manufactured with insufficient salt fill, which can result 
in an inability to detect hot bleed air leaks. This proposed AD would 
require testing of all affected overheat detection sensing elements of 
the bleed air leak detection system, and replacement if necessary. This 
proposed AD would also prohibit the installation of affected parts. The 
FAA is proposing this AD to address the unsafe condition on these 
products.

DATES: The FAA must receive comments on this proposed AD by January 3, 
2023.

ADDRESSES: You may send comments, using the procedures found in 14 CFR 
11.43 and 11.45, by any of the following methods:

rulemaking.

Background

    Transport Canada Civil Aviation (TCCA), which is the aviation 
authority for Canada, has issued TCCA AD CF-2022-16R1, dated July 5, 
2022 (TCCA AD CF-2022-16R1) (also referred to after this as the MCAI), 
to correct an unsafe condition on Model CL-600-2B19 (Regional Jet 
Series 100 & 440), CL-600-2C10 (Regional Jet Series 700, 701 & 702), 
CL-600-2C11 (Regional Jet Series 550), CL-600-2D15 (Regional Jet Series 
705), CL-600-2D24 (Regional Jet Series 900), and CL-600-2E25 (Regional 
Jet Series 1000) airplanes. The MCAI states that MHI RJ Aviation ULC 
received reports from the supplier of the overheat detection sensing 
elements of a manufacturing quality escape. Some of the sensing 
elements of the bleed air leak detection system were manufactured with 
insufficient salt fill, which can result in an inability to detect hot 
bleed air leaks and cause damage to surrounding structures and systems 
that can prevent continued safe flight and landing.
    You may examine the MCAI in the AD docket at regulations.gov under 
Docket No. FAA-2022-1474.

Related Service Information Under 1 CFR Part 51

    The FAA reviewed MHI RJ Service Bulletin 601R-36-021, Revision D, 
dated May 25, 2022; including Appendix A, Revision B, dated March 14, 
2022; and MHI RJ Service Bulletin 670BA-36-025, Revision C, dated May 
25, 2022; including Appendix A, Revision B, dated Mar 14, 2022; 
Appendix B, dated October 21, 2021; and Appendix C, dated March 14, 
2022. This service information specifies procedures for testing 
affected bleed air leak detection system sensing elements (i.e., those 
marked with a date code before ``A2105'' (which corresponds to January 
31, 2021), with a part number defined in this service information) to 
determine if they are serviceable, and replacing failed sensing 
elements with serviceable ones. This service information also allows 
deferring the replacement of an affected part under certain conditions 
and allows operating the airplane with certain deactivated defective 
sensing elements. 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.

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 described 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. This proposed AD would 
also prohibit the installation of affected parts.

Costs of Compliance

    The FAA estimates that this AD, if adopted as proposed, would 
affect 1,126 airplanes of U.S. registry. The FAA estimates the 
following costs to comply with this proposed AD:

[[Page 69212]]

    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

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

    The FAA has included all known costs in its cost estimate. 
According to the manufacturer, however, some or all of the costs of 
this proposed 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

    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:
