This proposed rule would increase 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, these costs would be offset by the benefits derived by the operation of the Order. The various subcommittees’ meetings and the Committee’s meeting were widely publicized throughout the California olive industry. All interested persons were invited to attend the meetings and encouraged to participate in any deliberations on all issues. Like all meetings, the subcommittee meetings held on November 5, 2020, and the full Committee meeting held on December 8, 2020, were public meetings and all entities, both large and small, were able to express views on this issue. Interested persons are invited to submit comments on this proposed rule, including the regulatory and information collection 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 the OMB and assigned OMB No. 0581–0178, Vegetable and Specialty 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 California olive 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. USDA has not identified any relevant Federal rules that duplicate, overlap, or conflict with this proposed rule.

Any commentary that the FAA receives which is not specifically designated as CBI will be placed in the public docket for this rulemaking. Background Transport Canada, which is the aviation authority of Canada, has issued Canadian AD CF–2017–16, dated May 17, 2017, to correct an unsafe condition for Bell Model 429 helicopters, serial numbers 57001 and subsequent. Transport Canada advises that Bell has established life limits and CMR tasks for various parts and accordingly revised Chapter 4—Airworthiness Limitations VerDate Sep<11>2014 16:26 Apr 07, 2021 Jkt 253001 Schedule of Bell Helicopter 429 Maintenance Manual BHT–429–MM–1 to Revision 26, dated September 9, 2016 (BHT–429–MM–1). Transport Canada states that failure to replace life-limited parts or perform CMR tasks as specified could result in an unsafe condition. Accordingly, the Transport Canada AD requires updating the maintenance schedule for the parts affected with the airworthiness life limits and CMR tasks in Revision 26 of BHT–429–MM–1. FAA’s Determination 18219 Proposed AD Requirements in This NPRM This proposed AD would require establishing a life limit for certain partnumbered tail rotor outboard flapping bearings and a certain part-numbered hoist kit cable cutter cartridge. This proposed AD would also require establishing recurring CMR tasks for a certain part-numbered wheeled landing gear system, float/life raft kit, and hoist kit. Depending on the results of the CMR tasks, this proposed AD would also require corrective action. These helicopters have been approved by the aviation authority of Canada and are approved for operation in the United States. Pursuant to the FAA’s bilateral agreement with Canada, Transport Canada, its technical representative, has notified the FAA of the unsafe condition described in its AD. The FAA is proposing this AD after evaluating all known relevant information and determining that the unsafe condition described previously is likely to exist or develop on other helicopters of the same type design. Differences Between This Proposed AD and the Transport Canada AD Related Service Information The FAA estimates that this AD, if adopted as proposed, would affect 110 helicopters of U.S. Registry. Labor costs are estimated at $85 per work-hour. Based on these numbers, the FAA estimates the following costs in order to comply with this proposed AD. Replacing a tail rotor outboard flapping bearing would take about 4 work-hours and parts would cost about $7,500 for an estimated cost of $7,840 per helicopter and $862,400 for the U.S. fleet, per replacement cycle. Replacing a hoist kit cable cutter cartridge would take about 3 work-hours and parts would cost about $5,200 for an estimated cost of $5,455 per helicopter and $600,050 for the U.S. fleet, per replacement cycle. Performing a functional check of the wheeled landing gear system would take about 4 work-hours for an estimated cost of $340 per helicopter and $37,400 for the U.S. fleet, per cycle. Performing a functional check of the float/life raft kit would take about 2 work-hours for an estimated cost of $170 per helicopter and $18,700 for the U.S. fleet, per cycle. Performing an operational check of the hoist kit cable anti-foul assembly would take about 2 work-hours for an estimated cost of $170 per helicopter and $18,700 for the U.S. fleet, per cycle. Cleaning, visually inspecting, and lubricating the rescue hoist cable would take about 2 work-hours for an estimated cost of $170 per helicopter and $18,700 for the U.S. fleet, per cycle. Performing an operational check of the The FAA reviewed Chapter 4— Airworthiness Limitations Schedule of BHT–429–MM–1. This service information specifies airworthiness life limits, inspection intervals, and CMR requirements for parts installed on Model 429 helicopters. Revision 26 of this service information establishes life limits for a certain part-numbered tail rotor flapping outboard bearing and hoist kit cartridge cable cutter and CMR requirements for a certain partnumbered wheeled landing gear system, float/life raft kit, and hoist kit. Additionally, the FAA reviewed Chapter 96–47—600-Pound External Hoist Electrical System—Operational Check, of Bell 429 Maintenance Manual Supplement For 600-Pound External Hoist Kit, BHT–429–MMS–4, Revision 1, dated March 14, 2014. This service information specifies inspection procedures and corrective action for various components of the hoist system. Lastly, the FAA reviewed Testing and Fault Isolation, pages 101–117/118, Cleaning, pages 401–405/406, and Scheduled Maintenance, pages 609– 611/612, of Goodrich Rescue Hoist System Component Maintenance Manual 25–00–38–1, dated July 15, 2009, for rescue hoist assembly part number 44316–12–102. This service information specifies maintenance procedures and lists replacement parts for this part-numbered Goodrich rescue hoist assembly. PO 00000 Frm 00004 Fmt 4702 Sfmt 4702 This proposed AD would require corrective action for failed CMR tasks, whereas the Transport Canada AD does not. The Transport Canada AD requires accomplishing an operational check of the hoist cable anti-foul assembly daily after the last flight, whereas this proposed AD would require this action before the first flight of the day involving a hoist operation instead. Costs of Compliance E:\FR\FM\08APP1.SGM 08APP1 18220 Federal Register / Vol. 86, No. 66 / Thursday, April 8, 2021 / Proposed Rules khammond on DSKJM1Z7X2PROD with PROPOSALS hoist kit speed limit switches and the electrical system would take about 0.5 work-hour for an estimated cost of $43 per helicopter and $4,730 for the U.S. fleet, per cycle. Performing a functional check of the cable cutter cartridge electrical system would take about 3 work-hours for an estimated cost of $255 per helicopter and $28,050 for the U.S. fleet, per cycle. The FAA has no way of determining the estimated costs to do allowable repairs based on the results of the CMR tasks. If required, replacing the float/life raft would take about 2 work-hours and parts would cost about $5,000 for an estimated cost of $5,170. Replacing the anti-foul assembly would take about 3 work-hours and parts would cost about $1,500 for an estimated cost of $1,755. Replacing a rescue hoist cable would take about 3 work-hours and parts would cost about $3,150 for an estimated cost of $3,405. Overhauling a rescue hoist assembly would cost about $83,000 and it would take about 8 workhours to remove and reinstall the hoist for a labor cost of $680, for a total estimated cost of $83,680 per helicopter, per overhaul cycle. Alternatively, replacing a hoist would take about 8 work-hours and parts would cost about $200,000 for an estimated cost of $200,680 per helicopter, per replacement cycle. 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 VerDate Sep<11>2014 16:26 Apr 07, 2021 Jkt 253001 on the distribution of power and responsibilities among the various levels of government. For the reasons discussed, 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.

Background

    Transport Canada, which is the aviation authority of Canada, has 
issued Canadian AD CF-2017-16, dated May 17, 2017, to correct an unsafe 
condition for Bell Model 429 helicopters, serial numbers 57001 and 
subsequent. Transport Canada advises that Bell has established life 
limits and CMR tasks for various parts and accordingly revised Chapter 
4--Airworthiness Limitations Schedule of Bell Helicopter 429 
Maintenance Manual BHT-429-MM-1 to Revision 26, dated September 9, 2016 
(BHT-429-MM-1). Transport Canada states that failure to replace life-
limited parts or perform CMR tasks as specified could result in an 
unsafe condition.
    Accordingly, the Transport Canada AD requires updating the 
maintenance schedule for the parts affected with the airworthiness life 
limits and CMR tasks in Revision 26 of BHT-429-MM-1.

FAA's Determination

    These helicopters have been approved by the aviation authority of 
Canada and are approved for operation in the United States. Pursuant to 
the FAA's bilateral agreement with Canada, Transport Canada, its 
technical representative, has notified the FAA of the unsafe condition 
described in its AD. The FAA is proposing this AD after evaluating all 
known relevant information and determining that the unsafe condition 
described previously is likely to exist or develop on other helicopters 
of the same type design.

Related Service Information

    The FAA reviewed Chapter 4--Airworthiness Limitations Schedule of 
BHT-429-MM-1. This service information specifies airworthiness life 
limits, inspection intervals, and CMR requirements for parts installed 
on Model 429 helicopters. Revision 26 of this service information 
establishes life limits for a certain part-numbered tail rotor flapping 
outboard bearing and hoist kit cartridge cable cutter and CMR 
requirements for a certain part-numbered wheeled landing gear system, 
float/life raft kit, and hoist kit.
    Additionally, the FAA reviewed Chapter 96-47--600-Pound External 
Hoist Electrical System--Operational Check, of Bell 429 Maintenance 
Manual Supplement For 600-Pound External Hoist Kit, BHT-429-MMS-4, 
Revision 1, dated March 14, 2014. This service information specifies 
inspection procedures and corrective action for various components of 
the hoist system.
    Lastly, the FAA reviewed Testing and Fault Isolation, pages 101-
117/118, Cleaning, pages 401-405/406, and Scheduled Maintenance, pages 
609-611/612, of Goodrich Rescue Hoist System Component Maintenance 
Manual 25-00-38-1, dated July 15, 2009, for rescue hoist assembly part 
number 44316-12-102. This service information specifies maintenance 
procedures and lists replacement parts for this part-numbered Goodrich 
rescue hoist assembly.

Proposed AD Requirements in This NPRM

    This proposed AD would require establishing a life limit for 
certain part-numbered tail rotor outboard flapping bearings and a 
certain part-numbered hoist kit cable cutter cartridge. This proposed 
AD would also require establishing recurring CMR tasks for a certain 
part-numbered wheeled landing gear system, float/life raft kit, and 
hoist kit. Depending on the results of the CMR tasks, this proposed AD 
would also require corrective action.

Differences Between This Proposed AD and the Transport Canada AD

    This proposed AD would require corrective action for failed CMR 
tasks, whereas the Transport Canada AD does not. The Transport Canada 
AD requires accomplishing an operational check of the hoist cable anti-
foul assembly daily after the last flight, whereas this proposed AD 
would require this action before the first flight of the day involving 
a hoist operation instead.

Costs of Compliance

    The FAA estimates that this AD, if adopted as proposed, would 
affect 110 helicopters of U.S. Registry. Labor costs are estimated at 
$85 per work-hour. Based on these numbers, the FAA estimates the 
following costs in order to comply with this proposed AD.
    Replacing a tail rotor outboard flapping bearing would take about 4 
work-hours and parts would cost about $7,500 for an estimated cost of 
$7,840 per helicopter and $862,400 for the U.S. fleet, per replacement 
cycle. Replacing a hoist kit cable cutter cartridge would take about 3 
work-hours and parts would cost about $5,200 for an estimated cost of 
$5,455 per helicopter and $600,050 for the U.S. fleet, per replacement 
cycle.
    Performing a functional check of the wheeled landing gear system 
would take about 4 work-hours for an estimated cost of $340 per 
helicopter and $37,400 for the U.S. fleet, per cycle. Performing a 
functional check of the float/life raft kit would take about 2 work-
hours for an estimated cost of $170 per helicopter and $18,700 for the 
U.S. fleet, per cycle.
    Performing an operational check of the hoist kit cable anti-foul 
assembly would take about 2 work-hours for an estimated cost of $170 
per helicopter and $18,700 for the U.S. fleet, per cycle. Cleaning, 
visually inspecting, and lubricating the rescue hoist cable would take 
about 2 work-hours for an estimated cost of $170 per helicopter and 
$18,700 for the U.S. fleet, per cycle. Performing an operational check 
of the

[[Page 18220]]

hoist kit speed limit switches and the electrical system would take 
about 0.5 work-hour for an estimated cost of $43 per helicopter and 
$4,730 for the U.S. fleet, per cycle. Performing a functional check of 
the cable cutter cartridge electrical system would take about 3 work-
hours for an estimated cost of $255 per helicopter and $28,050 for the 
U.S. fleet, per cycle.
    The FAA has no way of determining the estimated costs to do 
allowable repairs based on the results of the CMR tasks. If required, 
replacing the float/life raft would take about 2 work-hours and parts 
would cost about $5,000 for an estimated cost of $5,170. Replacing the 
anti-foul assembly would take about 3 work-hours and parts would cost 
about $1,500 for an estimated cost of $1,755. Replacing a rescue hoist 
cable would take about 3 work-hours and parts would cost about $3,150 
for an estimated cost of $3,405. Overhauling a rescue hoist assembly 
would cost about $83,000 and it would take about 8 work-hours to remove 
and reinstall the hoist for a labor cost of $680, for a total estimated 
cost of $83,680 per helicopter, per overhaul cycle. Alternatively, 
replacing a hoist would take about 8 work-hours and parts would cost 
about $200,000 for an estimated cost of $200,680 per helicopter, per 
replacement cycle.

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, 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.
