The purpose of these notices is to give interested persons an opportunity to participate in the rule making prior to the adoption of the final rules. DEPARTMENT OF TRANSPORTATION Federal Aviation Administration 14 CFR Part 39 [Docket No. FAA–2021–0559; Project Identifier MCAI–2021–00079–R] RIN 2120–AA64 Airworthiness Directives; Airbus Helicopters Federal Aviation Administration (FAA), DOT. ACTION: Notice of proposed rulemaking (NPRM). AGENCY: The FAA proposes to supersede airworthiness directive (AD) 2020–24–03 which applies to certain Airbus Helicopters Model AS350B, AS350BA, AS350B1, AS350B2, AS350D, AS355E, AS355F, AS355F1, and AS355F2 helicopters. AD 2020–24– 03 requires testing the UP/DOWN switches of a certain part-numbered DUNLOP cyclic stick grip, installing a placard, and revising the existing Rotorcraft Flight Manual (RFM) for your helicopter, or removing the DUNLOP cyclic stick grip. Since the FAA issued AD 2020–24–03, Airbus Helicopters developed a modification procedure for the electrical wiring of the hoist control of the DUNLOP cyclic stick grip. This proposed AD would retain some requirements of AD 2020–24–03 and would also require incorporating the new modification, and removing the placard and the RFM amendment installed previously as required by AD 2020–24–03. The proposed additional actions would be required as specified in a European Union Aviation Safety Agency (EASA) AD, which is proposed for incorporation by reference (IBR). 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 August 26, 2021. khammond on DSKJM1Z7X2PROD with PROPOSALS SUMMARY: VerDate Sep<11>2014 17:30 Jul 09, 2021 Jkt 253001 You may send comments, using the procedures found in 14 CFR 11.43 and 11.45, by any of the following methods: • Federal eRulemaking Portal: Go to https://www.regulations.gov.

E:\FR\FM\12JYP1.SGM 12JYP1 Federal Register / Vol. 86, No. 130 / Monday, July 12, 2021 / Proposed Rules Background The FAA issued AD 2020–24–03, Amendment 39–21333 (85 FR 76955, December 1, 2020), (AD 2020–24–03), which applies to Airbus Helicopters Model AS350B, AS350BA, AS350B1, AS350B2, AS350D, AS355E, AS355F, AS355F1, and AS355F2 helicopters with DUNLOP cyclic stick grip manufacturer part number (MP/N) AC66444 with UP/DOWN switches for rescue hoist control installed. AD 2020– 24–03 requires accomplishing a ground test of the UP/DOWN switches of DUNLOP cyclic stick grip for proper function before each hoist operation. If there is any uncommanded hoist action, AD 2020–24–03 requires removing the DUNLOP cyclic stick grip from service. If DUNLOP cyclic stick grip MP/N AC66444 is installed, before the next operation, AD 2020–24–03 also requires installing a placard and revising the existing RFM for your helicopter to prohibit the use of the UP/DOWN switches of the DUNLOP cyclic stick grip. Alternatively, AD 2020–24–03 allows removing DUNLOP cyclic stick grip MP/N AC66444, however before the DUNLOP cyclic stick grip is re-installed, AD 2020–24–03 requires accomplishing a ground test of the UP/DOWN switches and installing the placard and revising the existing RFM for your helicopter. AD 2020–24–03 also prohibits installing an affected DUNLOP cyclic stick grip unless the ground testing of the UP/ DOWN switches has been accomplished, the placard has been installed, and the existing RFM for your helicopter has been revised. The FAA issued AD 2020–24–03 to prevent an inadvertent activation of the rescue hoist cable cutter and consequent detachment of an external load or person from the helicopter hoist. This unsafe condition could result in personal injury or injury to persons on the ground. khammond on DSKJM1Z7X2PROD with PROPOSALS Actions Since AD 2020–24–03 Was Issued Since the FAA issued AD 2020–24– 03, Airbus Helicopters developed a modification (MOD) MC20096 and issued service information that provides instructions for modifying the electrical wiring of the hoist control on DUNLOP cyclic stick grips. EASA, which is the Technical Agent for the Member States of the European Union, has issued EASA AD 2021–0023, dated January 19, 2021 (EASA AD 2021–0023) to correct an unsafe condition for Airbus Helicopters Model AS 350 and AS 355 helicopters. This proposed AD was prompted by Airbus Helicopters developing MOD VerDate Sep<11>2014 17:30 Jul 09, 2021 Jkt 253001 MC20096 and Airbus Helicopters issuing service information for performing this modification on the DUNLOP cyclic stick. The FAA is proposing this AD to address inadvertent activation of the rescue hoist cable cutter function and consequent detachment of an external load or person from the helicopter hoist, possibly resulting in personal injury, or injury to persons on the ground. See EASA AD 2021–0023 for additional background information. Related Service Information Under 1 CFR Part 51 EASA AD 2021–0023 specifies procedures for installing the placard and revising the Flight Manual to prohibit the use of the UP/DOWN switches of the DUNLOP cyclic stick MP/N AC66444. EASA AD 2021–0023 also specifies procedures for modifying the electrical wiring of the DUNLOP cyclic stick and removing both the placard and RFM amendment previously installed. 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 and Requirements of This Proposed AD These helicopters have been approved by the aviation authority of another country, and are approved for operation in the United States. Pursuant to the bilateral agreement with the State of Design Authority, the FAA has been notified of the unsafe condition described in the EASA AD referenced above. The FAA is proposing this AD after evaluating all the relevant information and determining the unsafe condition described previously is likely to exist or develop in other products of these same type designs. Explanation of Retained Requirements Although this proposed AD does not explicitly restate the requirements of AD 2020–24–03, this proposed AD would retain certain requirements of AD 2020– 24–03. Those requirements are referenced in EASA AD 2021–0023, which, in turn, is referenced in paragraph (g) of this proposed AD. Proposed AD Requirements This proposed AD would require accomplishing the actions specified in EASA AD 2021–0023 described previously, as incorporated by reference, except for any differences identified as exceptions in the regulatory text of this proposed AD and except as discussed under ‘‘Differences PO 00000 Frm 00002 Fmt 4702 Sfmt 4702 36517 Between this Proposed AD and EASA AD 2021–0023.’’ Explanation of Required Compliance Information In the FAA’s ongoing efforts to improve the efficiency of the AD process, the FAA developed a process to use certain civil aviation authority (CAA) ADs as the primary source of information for compliance with requirements for corresponding FAA ADs. The FAA has been coordinating this process with manufacturers and CAAs. As a result, EASA AD 2021–0023 will be incorporated by reference in the FAA final rule. This proposed AD would, therefore, require compliance with EASA AD 2021–0023 in its entirety, through that incorporation, except for any differences identified as exceptions in the regulatory text of this proposed AD. Using common terms that are the same as the heading of a particular section in EASA AD 2021– 0023 does not mean that operators need comply only with that section. For example, where the AD requirement refers to ‘‘all required actions and compliance times,’’ compliance with this AD requirement is not limited to the section titled ‘‘Required Action(s) and Compliance Time(s)’’ in EASA AD 2021–0023. Service information specified in EASA AD 2021–0023 that is required for compliance with it will be available at https://www.regulations.gov by searching for and locating Docket No. FAA–2021–0559 after the FAA final rule is published. Differences Between This Proposed AD and EASA AD 2021–0023 For helicopters with DUNLOP cyclic stick grip MP/N AC66444 with UP/ DOWN switches for rescue hoist control installed, this proposed AD would require accomplishing a ground test of the UP/DOWN switches for proper function before each hoist operation, whereas the EASA AD does not. Where EASA AD 2021–0023 refers to its effective date or the effective date of EASA Emergency AD 2020–0217–E, dated October 8, 2020, this proposed AD would require using the effective date of this AD. Where the service information referenced in EASA AD 2021–0023 specifies ‘‘work must be performed on the helicopter by the operator,’’ this proposed AD would require that the work be accomplished by a mechanic that meets the requirements of 14 CFR part 65 subpart D. Where the service information referenced in EASA AD 2021–0023 specifies to discard certain placards and Flight Manual pages (that were required by EASA AD 2020–0217– E), this proposed AD would require E:\FR\FM\12JYP1.SGM 12JYP1 36518 Federal Register / Vol. 86, No. 130 / Monday, July 12, 2021 / Proposed Rules removing them instead. EASA AD 2021–0023 requires operators to ‘‘inform all flight crews’’ and thereafter to ‘‘operate the helicopter accordingly.’’ However, this proposed AD would not require those actions. Where paragraph (4) of EASA AD 2020–0023 allows modifying a Group 2 helicopter into a Group 1 helicopter, this proposed AD would also require accomplishing the requirements of paragraph (g)(1) of this AD. Finally, the service information referenced in EASA AD 2021–0023 requires reporting certain information, whereas this proposed AD would not. khammond on DSKJM1Z7X2PROD with PROPOSALS Costs of Compliance The FAA estimates that this proposed AD would affect 390 helicopters of U.S. Registry. The FAA estimates that operators may incur the following costs in order to comply with this proposed AD. Labor costs are estimated at $85 per work-hour. Accomplishing a ground test of the UP/DOWN switches for proper function takes a minimal amount of time for a nominal cost. Replacing a DUNLOP cyclic stick grip, if required, takes about 2.5 work-hours and parts cost about $2,500 for an estimated cost of $2,713. Installing the placard and revising the existing RFM for your helicopter would take about 0.5 work-hour for an estimated cost of $43 per helicopter and $16,770 for the U.S. fleet. Modifying the electrical wiring of the DUNLOP cyclic stick would take up to 4 work-hours and parts would cost $2,147 for an estimated cost of up to $2,487 per helicopter and $969,930 for the U.S. fleet. Removing the placard and revising the existing RFM for your helicopter would take about 0.5 workhour for an estimated cost of $43 per helicopter and $16,770 for the U.S. fleet. 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 VerDate Sep<11>2014 17:30 Jul 09, 2021 Jkt 253001 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: PART 39—AIRWORTHINESS DIRECTIVES 1.

ACTION: Proposed rule; request for comments. AGENCY: NMFS proposes to approve and implement Framework Adjustment 62 for Whiting, Red Hake, and Offshore Hake to the Northeast Multispecies Fishery Management Plan. The purpose of this action is to establish a 10-year rebuilding plan and adjust management measures for the overfished southern red hake stock. This action is necessary to meet the statutory requirements for an overfished stock and rebuilding plan consistent with the Magnuson-Stevens Fishery Conservation and Management Act. DATES: Comments must be received by July 27, 2021. ADDRESSES: The New England Fishery Management Council has prepared a draft environmental assessment (EA) for this action that describes the proposed measures in Framework Adjustment 62, other considered alternatives, and analyzes the impacts of the proposed measures and alternatives. The Council submitted a draft of Framework 62 to NMFS that includes the draft EA, a description of the Council’s preferred alternatives, and the Council’s rationale for selecting each alternative. Copies of the draft Framework 62, the draft EA, and information on the economic impacts of this proposed rulemaking are available upon request from Thomas A.

FOR FURTHER INFORMATION CONTACT: Laura Hansen, Fishery Management Specialist, 978–281–9225. SUPPLEMENTARY INFORMATION: Background In January 2018, the southern red hake stock was declared overfished. To meet the Magnuson-Stevens Act requirements of an overfished stock, a rebuilding plan and associated management measure changes are necessary to prevent overfishing, ensure adequate rebuilding, and help achieve optimum yield in the fishery. The New England Fishery Management Council took final action on this framework at its June 2020 meeting and submitted the action to us in mid-August 2020. Proposed Action Framework 62 would establish a 10year rebuilding schedule for southern red hake. The proposed rebuilding schedule is a range from a minimum associated with a similar increase in biomass that occurred during 2006– 2011 to a longer duration that accounts for biological characteristics of red hake. Southern red hake are fully mature, on average, at age 3 and the maximum observed age is 10 years in 2011–2019 survey data. By applying the estimated maturation rate and using biomass at age as a guide, and making reasonable assumptions that fertility (increases by 5 percent per year after age 3) and egg viability (full viability at age 5) increase with age, the Whiting Plan Development Team estimated that 50 percent of lifetime egg production of an unfished female occurs at 4.4 years. By definition, it would take 50 percent of a female’s egg production to exactly replace itself and its mate with offspring that would spawn a successive generation. It would E:\FR\FM\12JYP1.SGM 12JYP1

Airworthiness Directives; Airbus Helicopters

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: The FAA proposes to supersede airworthiness directive (AD) 
2020-24-03 which applies to certain Airbus Helicopters Model AS350B, 
AS350BA, AS350B1, AS350B2, AS350D, AS355E, AS355F, AS355F1, and AS355F2 
helicopters. AD 2020-24-03 requires testing the UP/DOWN switches of a 
certain part-numbered DUNLOP cyclic stick grip, installing a placard, 
and revising the existing Rotorcraft Flight Manual (RFM) for your 
helicopter, or removing the DUNLOP cyclic stick grip. Since the FAA 
issued AD 2020-24-03, Airbus Helicopters developed a modification 
procedure for the electrical wiring of the hoist control of the DUNLOP 
cyclic stick grip. This proposed AD would retain some requirements of 
AD 2020-24-03 and would also require incorporating the new 
modification, and removing the placard and the RFM amendment installed 
previously as required by AD 2020-24-03. The proposed additional 
actions would be required as specified in a European Union Aviation 
Safety Agency (EASA) AD, which is proposed for incorporation by 
reference (IBR). The FAA is proposing this AD to address the unsafe 
condition on these products.

Background

    The FAA issued AD 2020-24-03, Amendment 39-21333 (85 FR 76955, 
December 1, 2020), (AD 2020-24-03), which applies to Airbus Helicopters 
Model AS350B, AS350BA, AS350B1, AS350B2, AS350D, AS355E, AS355F, 
AS355F1, and AS355F2 helicopters with DUNLOP cyclic stick grip 
manufacturer part number (MP/N) AC66444 with UP/DOWN switches for 
rescue hoist control installed. AD 2020-24-03 requires accomplishing a 
ground test of the UP/DOWN switches of DUNLOP cyclic stick grip for 
proper function before each hoist operation. If there is any 
uncommanded hoist action, AD 2020-24-03 requires removing the DUNLOP 
cyclic stick grip from service. If DUNLOP cyclic stick grip MP/N 
AC66444 is installed, before the next operation, AD 2020-24-03 also 
requires installing a placard and revising the existing RFM for your 
helicopter to prohibit the use of the UP/DOWN switches of the DUNLOP 
cyclic stick grip. Alternatively, AD 2020-24-03 allows removing DUNLOP 
cyclic stick grip MP/N AC66444, however before the DUNLOP cyclic stick 
grip is re-installed, AD 2020-24-03 requires accomplishing a ground 
test of the UP/DOWN switches and installing the placard and revising 
the existing RFM for your helicopter. AD 2020-24-03 also prohibits 
installing an affected DUNLOP cyclic stick grip unless the ground 
testing of the UP/DOWN switches has been accomplished, the placard has 
been installed, and the existing RFM for your helicopter has been 
revised. The FAA issued AD 2020-24-03 to prevent an inadvertent 
activation of the rescue hoist cable cutter and consequent detachment 
of an external load or person from the helicopter hoist. This unsafe 
condition could result in personal injury or injury to persons on the 
ground.

Actions Since AD 2020-24-03 Was Issued

    Since the FAA issued AD 2020-24-03, Airbus Helicopters developed a 
modification (MOD) MC20096 and issued service information that provides 
instructions for modifying the electrical wiring of the hoist control 
on DUNLOP cyclic stick grips.
    EASA, which is the Technical Agent for the Member States of the 
European Union, has issued EASA AD 2021-0023, dated January 19, 2021 
(EASA AD 2021-0023) to correct an unsafe condition for Airbus 
Helicopters Model AS 350 and AS 355 helicopters.
    This proposed AD was prompted by Airbus Helicopters developing MOD 
MC20096 and Airbus Helicopters issuing service information for 
performing this modification on the DUNLOP cyclic stick. The FAA is 
proposing this AD to address inadvertent activation of the rescue hoist 
cable cutter function and consequent detachment of an external load or 
person from the helicopter hoist, possibly resulting in personal 
injury, or injury to persons on the ground. See EASA AD 2021-0023 for 
additional background information.

Related Service Information Under 1 CFR Part 51

    EASA AD 2021-0023 specifies procedures for installing the placard 
and revising the Flight Manual to prohibit the use of the UP/DOWN 
switches of the DUNLOP cyclic stick MP/N AC66444. EASA AD 2021-0023 
also specifies procedures for modifying the electrical wiring of the 
DUNLOP cyclic stick and removing both the placard and RFM amendment 
previously installed.
    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 and Requirements of This Proposed AD

    These helicopters have been approved by the aviation authority of 
another country, and are approved for operation in the United States. 
Pursuant to the bilateral agreement with the State of Design Authority, 
the FAA has been notified of the unsafe condition described in the EASA 
AD referenced above. The FAA is proposing this AD after evaluating all 
the relevant information and determining the unsafe condition described 
previously is likely to exist or develop in other products of these 
same type designs.

Explanation of Retained Requirements

    Although this proposed AD does not explicitly restate the 
requirements of AD 2020-24-03, this proposed AD would retain certain 
requirements of AD 2020-24-03. Those requirements are referenced in 
EASA AD 2021-0023, which, in turn, is referenced in paragraph (g) of 
this proposed AD.

Proposed AD Requirements

    This proposed AD would require accomplishing the actions specified 
in EASA AD 2021-0023 described previously, as incorporated by 
reference, except for any differences identified as exceptions in the 
regulatory text of this proposed AD and except as discussed under 
``Differences Between this Proposed AD and EASA AD 2021-0023.''

Explanation of Required Compliance Information

    In the FAA's ongoing efforts to improve the efficiency of the AD 
process, the FAA developed a process to use certain civil aviation 
authority (CAA) ADs as the primary source of information for compliance 
with requirements for corresponding FAA ADs. The FAA has been 
coordinating this process with manufacturers and CAAs. As a result, 
EASA AD 2021-0023 will be incorporated by reference in the FAA final 
rule. This proposed AD would, therefore, require compliance with EASA 
AD 2021-0023 in its entirety, through that incorporation, except for 
any differences identified as exceptions in the regulatory text of this 
proposed AD. Using common terms that are the same as the heading of a 
particular section in EASA AD 2021-0023 does not mean that operators 
need comply only with that section. For example, where the AD 
requirement refers to ``all required actions and compliance times,'' 
compliance with this AD requirement is not limited to the section 
titled ``Required Action(s) and Compliance Time(s)'' in EASA AD 2021-
0023. Service information specified in EASA AD 2021-0023 that is 
required for compliance with it will be available at https://www.regulations.gov by searching for and locating Docket No. FAA-2021-
0559 after the FAA final rule is published.

Differences Between This Proposed AD and EASA AD 2021-0023

    For helicopters with DUNLOP cyclic stick grip MP/N AC66444 with UP/
DOWN switches for rescue hoist control installed, this proposed AD 
would require accomplishing a ground test of the UP/DOWN switches for 
proper function before each hoist operation, whereas the EASA AD does 
not. Where EASA AD 2021-0023 refers to its effective date or the 
effective date of EASA Emergency AD 2020-0217-E, dated October 8, 2020, 
this proposed AD would require using the effective date of this AD. 
Where the service information referenced in EASA AD 2021-0023 specifies 
``work must be performed on the helicopter by the operator,'' this 
proposed AD would require that the work be accomplished by a mechanic 
that meets the requirements of 14 CFR part 65 subpart D. Where the 
service information referenced in EASA AD 2021-0023 specifies to 
discard certain placards and Flight Manual pages (that were required by 
EASA AD 2020-0217-E), this proposed AD would require

[[Page 36518]]

removing them instead. EASA AD 2021-0023 requires operators to ``inform 
all flight crews'' and thereafter to ``operate the helicopter 
accordingly.'' However, this proposed AD would not require those 
actions. Where paragraph (4) of EASA AD 2020-0023 allows modifying a 
Group 2 helicopter into a Group 1 helicopter, this proposed AD would 
also require accomplishing the requirements of paragraph (g)(1) of this 
AD. Finally, the service information referenced in EASA AD 2021-0023 
requires reporting certain information, whereas this proposed AD would 
not.

Costs of Compliance

    The FAA estimates that this proposed AD would affect 390 
helicopters of U.S. Registry. The FAA estimates that operators may 
incur the following costs in order to comply with this proposed AD. 
Labor costs are estimated at $85 per work-hour.
    Accomplishing a ground test of the UP/DOWN switches for proper 
function takes a minimal amount of time for a nominal cost. Replacing a 
DUNLOP cyclic stick grip, if required, takes about 2.5 work-hours and 
parts cost about $2,500 for an estimated cost of $2,713. Installing the 
placard and revising the existing RFM for your helicopter would take 
about 0.5 work-hour for an estimated cost of $43 per helicopter and 
$16,770 for the U.S. fleet.
    Modifying the electrical wiring of the DUNLOP cyclic stick would 
take up to 4 work-hours and parts would cost $2,147 for an estimated 
cost of up to $2,487 per helicopter and $969,930 for the U.S. fleet. 
Removing the placard and revising the existing RFM for your helicopter 
would take about 0.5 work-hour for an estimated cost of $43 per 
helicopter and $16,770 for the U.S. fleet.

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
