SUPPLEMENTARY INFORMATION: Pursuant to Marketing Agreement and Order No. 959, as amended (7 CFR part 959), hereinafter referred to as the ‘‘Order,’’ and the applicable provisions of the Agricultural Marketing Agreement Act of 1937, as amended (7 U.S.C. 601–674), hereinafter referred to as the ‘‘Act,’’ it is hereby directed that a referendum be conducted to ascertain whether continuance of the Order is favored by producers. The referendum shall be conducted from September 21 through October 13, 2020, among onion producers in the production area. Only current Texas onion producers who were also engaged in the production of onions grown in South Texas during the period of August 1, 2018, through July 31, 2019, may participate in the continuance referendum. USDA has determined that continuance referenda are an effective means for determining whether producers favor the continuation of marketing order programs. The Order will continue in effect if two-thirds or more of the producers voting in the referendum, or producers of more than two-thirds of the volume of onions grown in South Texas represented in the referendum, favor continuance. In evaluating the merits of continuance versus termination, USDA will not exclusively consider the results of the continuance referendum. USDA will also consider all other relevant information regarding the operation of the Order and relative benefits and disadvantages to producers, handlers, and consumers to determine whether continued operation of the Order would tend to effectuate the declared policy of the Act. In accordance with the Paperwork Reduction Act of 1995 (44 U.S.C. chapter 35), the ballots used in the referendum have been approved by the Office of Management and Budget (OMB) and have been assigned OMB No. 0581–0178 Vegetable and Specialty Crops. It has been estimated it will take an average of 20 minutes for each of the approximately 100 onion producers to cast a ballot. Participation is voluntary. Ballots postmarked after October 13, 2020, will not be included in the vote tabulation. Abigail Campos and Christian D. Nissen of the Southeast Marketing Field PO 00000 Frm 00001 Fmt 4702 Sfmt 4702 Office, Specialty Crops Program, AMS, USDA, are hereby designated as the referendum agents of the Secretary of Agriculture to conduct this referendum. The procedure applicable to the referendum shall be the ‘‘Procedure for the Conduct of Referenda in Connection With Marketing Orders for Fruits, Vegetables, and Nuts Pursuant to the Agricultural Marketing Agreement Act of 1937, as Amended’’ (7 CFR part 900.400 et seq.). Ballots will be mailed to all producers of record and may also be obtained from the referendum agents or from their appointees.

Background The FAA proposes to adopt a new AD for Sikorsky Model S–92A helicopters, with serial numbers (S/Ns) 920006 through 920334, inclusive. The FAA learned of a quality escape involving the manufacture of landing gear components, including the threaded hinge pin and the MLG and NLG actuator pins, that were not made to specification and have non-conforming threads that reduce the fatigue life of the component. Failure of the threaded hinge pin or the actuator pins on the MLG or NLG may result in collapse of PO 00000 Frm 00002 Fmt 4702 Sfmt 4702 55389 the landing gear and reduced ability of the flight crew to land the helicopter. This proposed AD would require the removal from service of certain serialnumbered threaded hinge pins part number (P/N) 92250–12281–101 and certain serial-numbered MLG and NLG actuator pins P/N 92250–12287–101 and 92250–12287–103 identified in this proposed AD. This condition, if not addressed, could result in failure of components on the MLG and NLG, collapse of the landing gear and damage to the helicopter, and reduced ability to control the helicopter during landing. FAA’s Determination The FAA is issuing this NPRM because the agency evaluated all the relevant information and determined the unsafe condition described previously is likely to exist or develop in other products of the same type design. Related Service Information Under 1 CFR Part 51 The FAA reviewed Sikorsky Aircraft Corporation Alert Service Bulletin 92– 32–008, Basic Issue, dated January 21, 2020 (‘‘the ASB’’). The ASB describes procedures for a one-time inspection and replacement of non-conforming components on the MLG and NLG. 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. Proposed AD Requirements This proposed AD would require a one-time inspection of the landing gear and removal from service of threaded hinge pins and MLG and NLG actuator pins with non-conforming threads. Differences Between This Proposed AD and the Service Information This proposed AD would require replacement of only affected hinge pins and MLG and NLG actuator pins. The ASB requires replacement of additional parts, such as the MLG and NLG crossbolt and the MLG and NLG upper nut. The FAA has determined that the MLG and NLG crossbolt and the MLG and NLG upper nut fail in a safe and contained manner and therefore are not subject to this AD. In addition, this proposed AD would require this one-time inspection to occur within 300 hours time in service after the effective date of this AD and any affected hinge pins and MLG and NLG actuator pins be removed from service before further flight. The ASB requires that the inspection and replacement of the affected hinge pins E:\FR\FM\08SEP1.SGM 08SEP1 55390 Federal Register / Vol. 85, No. 174 / Tuesday, September 8, 2020 / Proposed Rules and MLG and NLG actuator pins occur no later than January 21, 2021. Costs of Compliance The FAA estimates that this AD, as proposed, would affect 85 helicopters of U.S. registry. The FAA estimates the following costs to comply with this proposed AD: ESTIMATED COSTS Action Labor cost Visually inspect landing gear (right MLG assembly, left MLG assembly, and NLG kit). 1 work-hour × $85 per hour = $85 (per landing gear). The FAA estimates the following costs to do any necessary replacements that would be required based on the Parts cost $0 results of the proposed inspection. The FAA has no way of determining the Cost on U.S. operators Cost per product $255 (three landing gear installed on each helicopter). $21,675 number of helicopters that might need these replacements: ON-CONDITION COSTS Labor cost Replace threaded hinge pin, P/N 92250–12281–101 .. Replace MLG/NLG actuator pin, P/N 92250–12287– 101. Replace MLG/NLG actuator pin, P/N 92250–12287– 103. 1 work-hour × $85 per hour = $85 ............................... 1 work-hour × $85 = $85 .............................................. $2,816 557 $2,901 642 1 work-hour × $85 = $85 .............................................. 609 694 jbell on DSKJLSW7X2PROD with PROPOSALS According to the manufacturer, some of the costs of this proposed AD may be covered under warranty, thereby reducing the cost impact on affected individuals. The FAA does not control warranty coverage for affected individuals. As a result, The FAA has included all costs in its cost estimate. 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 has determined that this proposed AD would not have federalism implications under Executive Order 13132. This proposed AD would not VerDate Sep<11>2014 16:00 Sep 04, 2020 Jkt 250001 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) Will not affect intrastate aviation in Alaska, and (3) Will 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.

ACTION: Notice of proposed rulemaking (NPRM). AGENCY: The FAA proposes to supersede Airworthiness Directive (AD) 2019–22–10, which applies to all The Boeing Company Model 737–600, –700, –700C, –800, –900, and –900ER series airplanes. AD 2019–22–10 requires repetitive inspections for cracking of the left- and right-hand side outboard chords of frame fittings and failsafe straps at a certain station around eight fasteners, and repair if any cracking is found. Since the FAA issued AD 2019– 22–10, it was determined that the initial inspection threshold and repetitive inspection interval are inadequate to address the cracking in a timely manner. For certain airplanes, this proposed AD would reduce the compliance time for the initial inspection, and for all airplanes this proposed AD would reduce the compliance time for the repetitive inspections.

the following paragraph, and other information as described in 14 CFR 
11.35, the FAA will post all comments received, without change, to 
https://www.regulations.gov, including any personal information you 
provide. The FAA will also post a report summarizing each substantive 
verbal contact received about this proposal.

Confidential Business Information

    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 Dorie Resnik, Aerospace Engineer, Boston ACO, 
FAA, 1200 District Avenue, Burlington, MA 01803. 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 proposes to adopt a new AD for Sikorsky Model S-92A 
helicopters, with serial numbers (S/Ns) 920006 through 920334, 
inclusive. The FAA learned of a quality escape involving the 
manufacture of landing gear components, including the threaded hinge 
pin and the MLG and NLG actuator pins, that were not made to 
specification and have non-conforming threads that reduce the fatigue 
life of the component. Failure of the threaded hinge pin or the 
actuator pins on the MLG or NLG may result in collapse of the landing 
gear and reduced ability of the flight crew to land the helicopter. 
This proposed AD would require the removal from service of certain 
serial-numbered threaded hinge pins part number (P/N) 92250-12281-101 
and certain serial-numbered MLG and NLG actuator pins P/N 92250-12287-
101 and 92250-12287-103 identified in this proposed AD. This condition, 
if not addressed, could result in failure of components on the MLG and 
NLG, collapse of the landing gear and damage to the helicopter, and 
reduced ability to control the helicopter during landing.

FAA's Determination

    The FAA is issuing this NPRM because the agency evaluated all the 
relevant information and determined the unsafe condition described 
previously is likely to exist or develop in other products of the same 
type design.

Related Service Information Under 1 CFR Part 51

    The FAA reviewed Sikorsky Aircraft Corporation Alert Service 
Bulletin 92-32-008, Basic Issue, dated January 21, 2020 (``the ASB''). 
The ASB describes procedures for a one-time inspection and replacement 
of non-conforming components on the MLG and NLG. 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.

Proposed AD Requirements

    This proposed AD would require a one-time inspection of the landing 
gear and removal from service of threaded hinge pins and MLG and NLG 
actuator pins with non-conforming threads.

Differences Between This Proposed AD and the Service Information

    This proposed AD would require replacement of only affected hinge 
pins and MLG and NLG actuator pins. The ASB requires replacement of 
additional parts, such as the MLG and NLG crossbolt and the MLG and NLG 
upper nut. The FAA has determined that the MLG and NLG crossbolt and 
the MLG and NLG upper nut fail in a safe and contained manner and 
therefore are not subject to this AD.
    In addition, this proposed AD would require this one-time 
inspection to occur within 300 hours time in service after the 
effective date of this AD and any affected hinge pins and MLG and NLG 
actuator pins be removed from service before further flight. The ASB 
requires that the inspection and replacement of the affected hinge pins

[[Page 55390]]

and MLG and NLG actuator pins occur no later than January 21, 2021.

Costs of Compliance

    The FAA estimates that this AD, as proposed, would affect 85 
helicopters of U.S. registry.
    The FAA estimates the following costs to comply with this proposed 
AD:

                                                 Estimated Costs
----------------------------------------------------------------------------------------------------------------
                                                                                                   Cost on U.S.

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

    The FAA estimates the following costs to do any necessary 
replacements that would be required based on the results of the 
proposed inspection. The FAA has no way of determining the number of 
helicopters that might need these replacements:

                                               On-Condition Costs
----------------------------------------------------------------------------------------------------------------

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

    According to the manufacturer, some of the costs of this proposed 
AD may be covered under warranty, thereby reducing the cost impact on 
affected individuals. The FAA does not control warranty coverage for 
affected individuals. As a result, The FAA has included all costs in 
its cost estimate.

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 has 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) Will not affect intrastate aviation in Alaska, and
    (3) Will 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

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

0
1. The authority citation for part 39 continues to read as follows:

    Authority:  49 U.S.C. 106(g), 40113, 44701.


Sec.  39.13  [Amended]

0
2. The FAA amends Sec.  39.13 by adding the following new airworthiness 
directive (AD):

Sikorsky Aircraft Corporation: Docket No. FAA-2020-0791; Project 
Identifier AD-2020-00676-R.

(a) Comments Due Date

    The FAA must receive comments by October 23, 2020.

(b) Affected ADs

    None.

(c) Applicability

    This AD applies to Sikorsky Aircraft Corporation (Sikorsky) 
Model S-92A helicopters, certificated in any category, with serial 
numbers (S/Ns) 920006 through 920334 inclusive.

(d) Subject

    Joint Aircraft System Component (JASC) Code 3220, Nose/Tail 
Landing Gear; 3210, Main Landing Gear.

(e) Unsafe Condition

    This AD was prompted by the manufacturer determining that 
because of non-conforming threads, due to a quality escape, the life 
limit of the threaded hinge pin and main landing gear (MLG) and nose 
landing gear (NLG) actuator pins is reduced. The FAA is issuing this 
AD to prevent failure of components on the MLG and NLG. The unsafe 
condition, if not addressed, could result in damage to the 
helicopter and reduced ability to control the helicopter during 
landing.

[[Page 55391]]

(f) Compliance

    Comply with this AD within the compliance times specified, 
unless already done.

(g) Required Actions

    Within 300 hours time in service after the effective date of 
this AD, visually inspect the components of the right MLG assembly, 
left MLG assembly, and NLG kit for threaded hinge pins, part number 
(P/N) 92250-12281-101, and actuator pins, P/N 92240-12287-101 and
