Download as PDF 86260 Federal Register / Vol. 88, No. 238 / Wednesday, December 13, 2023 / Rules and Regulations procedure are impracticable, unnecessary, or contrary to the public interest, an agency may issue a rule without providing notice and an opportunity for public comment. AMS has determined that there is good cause for making this rule final without prior proposal and opportunity for comment because AMS is merely delaying the effective date and correcting one compliance date. AMS is delaying the effective date of the OLPS rule to be consistent with the requirements of the CRA as a matter of law and has no discretion in this matter. The compliance dates erroneously listed as January 5, 2029, in the OLPS final rule will now be corrected to January 2, 2029. These changes are administrative and minor in nature. Accordingly, AMS finds that there is good cause to dispense with notice and public procedure under 5 U.S.C. 553(b)(B). Administrative Pay-As-You-Go-Act of 2023 The U.S. Government Accountability Office (GAO) assessment of the OLPS final rule reported that AMS did not discuss the Administrative Pay-As-YouGo-Act of 2023 (Pub. L. 118–5, div. B, title III, 137 Stat 3) (Act) in the final rule.2 The Office of Management and Budget memorandum on the Administrative Pay-As-You-Go-Act of 2023 stated that the requirements of the Act ‘‘apply to all rules that have not yet been submitted to the Office of Information and Regulatory Affairs (OIRA) as of the date of this memorandum.’’ 3 Based on AMS’ understanding, analysis was not required. AMS submitted the OLPS final rule to OIRA on July 31, 2023, before the memorandum was published on September 1, 2023. However, AMS does confirm the Act does not apply to the OLPS final rule because it does not increase direct spending. Erin Morris, Associate Administrator, Agricultural Marketing Service.

Any commentary that the FAA receives that is not specifically designated as CBI will be placed in the public docket for this rulemaking. Background The FAA issued Emergency AD 2023– 24–51, dated November 21, 2023 (the emergency AD), to address an unsafe condition on all He´licopte`res Guimbal Model Cabri G2 helicopters. The FAA sent the emergency AD to all known U.S. owners and operators of these helicopters. The emergency AD requires repetitively inspecting certain partnumbered pilot and co-pilot cyclic stick bases for a crack and, depending on the results, removing the cracked cyclic stick base from service and replacing it with a serviceable cyclic stick base in accordance with a method approved by the FAA, EASA, or He´licopte`res Guimbal EASA Design Organization Approval (DOA). The emergency AD also prohibits installing an affected pilot or co-pilot cyclic stick base unless it is new (zero total hours time-in-service) or it has passed its required inspection. The emergency AD was prompted by EASA Emergency AD 2023–0204–E, dated November 20, 2023 (EASA AD 2023–0204–E), issued by EASA, which is the Technical Agent for the Member States of the European Union, to correct an unsafe condition on He´licopte`res Guimbal Model Cabri G2 helicopters. EASA AD 2023–0204–E states that further investigation determined that the root cause of the cracks is fatigue, primarily related to induced loads on the cyclic stick during pre-flight (free VerDate Sep<11>2014 15:50 Dec 12, 2023 Jkt 262001 play) checks. Accordingly, EASA AD 2023–0204–E requires repetitively inspecting certain part-numbered pilot and co-pilot cyclic stick bases and, depending on the results, corrective action. EASA AD 2023–0204–E also prohibits installing those pilot and copilot cyclic stick bases unless its requirements are met. You may examine EASA AD 2023– 0204–E in the AD docket at regulations.gov under Docket No. FAA– 2023–2239. The FAA is issuing this AD to detect a cracked pilot or co-pilot cyclic stick base. This condition, if not addressed, could result in failure of the pilot or copilot cyclic stick base and subsequent loss of control of the helicopter. Related Service Information Under 1 CFR Part 51 The FAA reviewed EASA AD 2023– 0204–E, which requires repetitively inspecting pilot cyclic stick base part number (P/N) G41–42–801 and co-pilot cyclic stick base P/Ns G41–43–801 and G41–43–802 for a crack. Depending on the results, EASA AD 2023–0204–E requires contacting HG [He´licopte`res Guimbal] for approved instructions to replace a cracked cyclic stick base and accomplishing those instructions accordingly. EASA AD 2023–0204–E also allows removing the dual control (co-pilot cyclic stick) instead of replacing a cracked co-pilot cyclic stick base. Lastly, EASA AD 2023–0204–E prohibits installing a specified pilot or co-pilot cyclic stick base unless it is a new (never installed before) part or, before installation, has passed its required inspection. The FAA also reviewed Guimbal Mandatory Service Bulletin SB 23–006, Revision B, dated November 14, 2023 (SB 23–006B), which specifies procedures for an initial and repetitive inspections of both the pilot and copilot cyclic bases for cracks. SB 23–006B specifies doing the inspection using a flashlight and in case of doubt, performing a dye-penetrant inspection. If there is a crack on the pilot’s side, SB 23–006B specifies grounding the helicopter and contacting HG [He´licopte`res Guimbal]; if there is a crack on the copilot’s side, SB 23–006B specifies removing the dual controls and contacting HG. 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 These helicopters have been approved by the aviation authority of the PO 00000 Frm 00003 Fmt 4700 Sfmt 4700 86261 European Union and are approved for operation in the United States. Pursuant to the FAA’s bilateral agreement with the European Union, EASA, its technical representative, has notified the FAA of the unsafe condition described in its emergency AD. The FAA is issuing this AD after evaluating all pertinent information and determining that the unsafe condition exists and is likely to exist or develop on other helicopters of the same type design. Requirements of This AD This AD requires accomplishing the actions specified in EASA AD 2023– 0204–E, described previously, as incorporated by reference, except for any differences identified as exceptions in the regulatory text of this AD and except as discussed under ‘‘Differences Between this AD and the EASA Emergency AD.’’ 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 some 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 2023– 0204–E is incorporated by reference in this FAA final rule. This AD, therefore, requires compliance with EASA AD 2023–0204–E in its entirety through that incorporation, except for any differences identified as exceptions in the regulatory text of this AD. Using common terms that are the same as the heading of a particular section in EASA AD 2023–0204–E 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 2023–0204–E. Service information referenced in EASA AD 2023–0204–E for compliance will be available at regulations.gov under Docket No. FAA–2023–2239 after this final rule is published. Differences Between This AD and the EASA Emergency AD The service information referenced in EASA AD 2023–0204–E specifies performing a dye-penetrant inspection in case of a doubt regarding if there is a crack, whereas this AD does not require that action. If there is cracked E:\FR\FM\13DER1.SGM 13DER1 86262 Federal Register / Vol. 88, No. 238 / Wednesday, December 13, 2023 / Rules and Regulations pilot or co-pilot cyclic stick base, EASA AD 2023–0204–E requires contacting HG [He´licopte`res Guimbal] for approved instructions to replace it with a serviceable part and accomplishing those instructions accordingly and the service information referenced in EASA AD 2023–0204–E specifies contacting HG [He´licopte`res Guimbal] or removing the dual controls and contacting HG [He´licopte`res Guimbal], whereas this AD requires removing the cracked cyclic stick base from service and replacing it with a serviceable cyclic stick base in accordance with a method approved by the FAA, EASA, or He´licopte`res Guimbal EASA DOA. khammond on DSKJM1Z7X2PROD with RULES Justification for Immediate Adoption and Determination of the Effective Date Section 553(b)(3)(B) of the Administrative Procedure Act (APA) (5 U.S.C. 551 et seq.) authorizes agencies to dispense with notice and comment procedures for rules when the agency, for ‘‘good cause,’’ finds that those procedures are ‘‘impracticable, unnecessary, or contrary to the public interest.’’ Under this section, an agency, upon finding good cause, may issue a final rule without providing notice and seeking comment prior to issuance. Further, section 553(d) of the APA authorizes agencies to make rules effective in less than thirty days, upon a finding of good cause. An unsafe condition exists that required the immediate adoption of Emergency AD 2023–24–51, issued on November 21, 2023, to all known U.S. owners and operators of these helicopters. The FAA found that the risk to the flying public justified waiving notice and comment prior to adoption of this rule because the affected component is part of an assembly that is critical to the control of a helicopter. As the FAA also has no information pertaining to the quantity of cracked components that may currently exist in the U.S. fleet or how quickly the condition may propagate to failure, the actions required by this AD must be accomplished before further flight for certain helicopters. These conditions still exist, therefore, notice and opportunity for prior public comment are impracticable and contrary to the public interest pursuant to 5 U.S.C. 553(b)(3)(B). In addition, the FAA finds that good cause exists pursuant to 5 U.S.C. 553(d) for making this amendment effective in less than 30 days, for the same reasons the FAA found good cause to forego notice and comment. VerDate Sep<11>2014 15:50 Dec 12, 2023 Jkt 262001 Regulatory Flexibility Act The requirements of the Regulatory Flexibility Act (RFA) do not apply when an agency finds good cause pursuant to 5 U.S.C. 553 to adopt a rule without prior notice and comment. Because the FAA has determined that it has good cause to adopt this rule without prior notice and comment, RFA analysis is not required. Costs of Compliance The FAA estimates that this AD affects 49 helicopters of U.S. Registry. Labor rates are estimated at $85 per work-hour. Based on these numbers, the FAA estimates the following costs to comply with this AD. Inspecting a pilot or co-pilot cyclic stick base takes a minimal amount of time for a nominal cost. If required, replacing a pilot cyclic stick base takes about 3 work-hours and parts cost about $1,585 for an estimated cost of $1,840 per helicopter; and replacing a co-pilot cyclic stick base takes about 1 workhour and parts cost about $711 for an estimated cost of $796 per helicopter. 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 This AD will not have federalism implications under Executive Order 13132. This AD will 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 that this AD: (1) Is not a ‘‘significant regulatory action’’ under Executive Order 12866, and PO 00000 Frm 00004 Fmt 4700 Sfmt 4700 (2) Will not affect intrastate aviation in Alaska. List of Subjects in 14 CFR Part 39 Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety. The Amendment Accordingly, under the authority delegated to me by the Administrator, the FAA amends 14 CFR part 39 as follows: PART 39—AIRWORTHINESS DIRECTIVES 1.

SUMMARY: The FAA is adopting a new airworthiness directive (AD) for all 
H[eacute]licopt[egrave]res Guimbal Model Cabri G2 helicopters. This AD 
was prompted by reports of a crack in the pilot cyclic stick base. This 
AD requires repetitively inspecting certain part-numbered pilot and co-
pilot cyclic stick bases and, depending on the results, corrective 
action. This AD also prohibits installing those pilot and co-pilot 
cyclic stick bases unless certain requirements are met. These actions 
are specified in a European Union Aviation Safety Agency (EASA) AD, 
which is incorporated by reference. The FAA previously sent this AD as 
an emergency AD to all known U.S. owners and operators of these 
helicopters. The FAA is issuing this AD to address the unsafe condition 
on these products.

DATES: This AD is effective December 28, 2023. Emergency AD 2023-24-51,

Background

    The FAA issued Emergency AD 2023-24-51, dated November 21, 2023 
(the emergency AD), to address an unsafe condition on all 
H[eacute]licopt[egrave]res Guimbal Model Cabri G2 helicopters. The FAA 
sent the emergency AD to all known U.S. owners and operators of these 
helicopters. The emergency AD requires repetitively inspecting certain 
part-numbered pilot and co-pilot cyclic stick bases for a crack and, 
depending on the results, removing the cracked cyclic stick base from 
service and replacing it with a serviceable cyclic stick base in 
accordance with a method approved by the FAA, EASA, or 
H[eacute]licopt[egrave]res Guimbal EASA Design Organization Approval 
(DOA). The emergency AD also prohibits installing an affected pilot or 
co-pilot cyclic stick base unless it is new (zero total hours time-in-
service) or it has passed its required inspection.
    The emergency AD was prompted by EASA Emergency AD 2023-0204-E, 
dated November 20, 2023 (EASA AD 2023-0204-E), issued by EASA, which is 
the Technical Agent for the Member States of the European Union, to 
correct an unsafe condition on H[eacute]licopt[egrave]res Guimbal Model 
Cabri G2 helicopters. EASA AD 2023-0204-E states that further 
investigation determined that the root cause of the cracks is fatigue, 
primarily related to induced loads on the cyclic stick during pre-
flight (free play) checks. Accordingly, EASA AD 2023-0204-E requires 
repetitively inspecting certain part-numbered pilot and co-pilot cyclic 
stick bases and, depending on the results, corrective action. EASA AD 
2023-0204-E also prohibits installing those pilot and co-pilot cyclic 
stick bases unless its requirements are met.
    You may examine EASA AD 2023-0204-E in the AD docket at 
regulations.gov under Docket No. FAA-2023-2239.
    The FAA is issuing this AD to detect a cracked pilot or co-pilot 
cyclic stick base. This condition, if not addressed, could result in 
failure of the pilot or co-pilot cyclic stick base and subsequent loss 
of control of the helicopter.

Related Service Information Under 1 CFR Part 51

    The FAA reviewed EASA AD 2023-0204-E, which requires repetitively 
inspecting pilot cyclic stick base part number (P/N) G41-42-801 and co-
pilot cyclic stick base P/Ns G41-43-801 and G41-43-802 for a crack. 
Depending on the results, EASA AD 2023-0204-E requires contacting HG 
[H[eacute]licopt[egrave]res Guimbal] for approved instructions to 
replace a cracked cyclic stick base and accomplishing those 
instructions accordingly. EASA AD 2023-0204-E also allows removing the 
dual control (co-pilot cyclic stick) instead of replacing a cracked co-
pilot cyclic stick base. Lastly, EASA AD 2023-0204-E prohibits 
installing a specified pilot or co-pilot cyclic stick base unless it is 
a new (never installed before) part or, before installation, has passed 
its required inspection.
    The FAA also reviewed Guimbal Mandatory Service Bulletin SB 23-006, 
Revision B, dated November 14, 2023 (SB 23-006B), which specifies 
procedures for an initial and repetitive inspections of both the pilot 
and copilot cyclic bases for cracks. SB 23-006B specifies doing the 
inspection using a flashlight and in case of doubt, performing a dye-
penetrant inspection. If there is a crack on the pilot's side, SB 23-
006B specifies grounding the helicopter and contacting HG 
[H[eacute]licopt[egrave]res Guimbal]; if there is a crack on the 
copilot's side, SB 23-006B specifies removing the dual controls and 
contacting HG.
    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

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

Requirements of This AD

    This AD requires accomplishing the actions specified in EASA AD 
2023-0204-E, described previously, as incorporated by reference, except 
for any differences identified as exceptions in the regulatory text of 
this AD and except as discussed under ``Differences Between this AD and 
the EASA Emergency AD.''

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 some 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 2023-0204-E is incorporated by reference in this FAA final 
rule. This AD, therefore, requires compliance with EASA AD 2023-0204-E 
in its entirety through that incorporation, except for any differences 
identified as exceptions in the regulatory text of this AD. Using 
common terms that are the same as the heading of a particular section 
in EASA AD 2023-0204-E 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 2023-0204-E. Service information 
referenced in EASA AD 2023-0204-E for compliance will be available at 
regulations.gov under Docket No. FAA-2023-2239 after this final rule is 
published.

Differences Between This AD and the EASA Emergency AD

    The service information referenced in EASA AD 2023-0204-E specifies 
performing a dye-penetrant inspection in case of a doubt regarding if 
there is a crack, whereas this AD does not require that action. If 
there is cracked

[[Page 86262]]

pilot or co-pilot cyclic stick base, EASA AD 2023-0204-E requires 
contacting HG [H[eacute]licopt[egrave]res Guimbal] for approved 
instructions to replace it with a serviceable part and accomplishing 
those instructions accordingly and the service information referenced 
in EASA AD 2023-0204-E specifies contacting HG 
[H[eacute]licopt[egrave]res Guimbal] or removing the dual controls and 
contacting HG [H[eacute]licopt[egrave]res Guimbal], whereas this AD 
requires removing the cracked cyclic stick base from service and 
replacing it with a serviceable cyclic stick base in accordance with a 
method approved by the FAA, EASA, or H[eacute]licopt[egrave]res Guimbal 
EASA DOA.

Justification for Immediate Adoption and Determination of the Effective 
Date

    Section 553(b)(3)(B) of the Administrative Procedure Act (APA) (5 
U.S.C. 551 et seq.) authorizes agencies to dispense with notice and 
comment procedures for rules when the agency, for ``good cause,'' finds 
that those procedures are ``impracticable, unnecessary, or contrary to 
the public interest.'' Under this section, an agency, upon finding good 
cause, may issue a final rule without providing notice and seeking 
comment prior to issuance. Further, section 553(d) of the APA 
authorizes agencies to make rules effective in less than thirty days, 
upon a finding of good cause.
    An unsafe condition exists that required the immediate adoption of 
Emergency AD 2023-24-51, issued on November 21, 2023, to all known U.S. 
owners and operators of these helicopters. The FAA found that the risk 
to the flying public justified waiving notice and comment prior to 
adoption of this rule because the affected component is part of an 
assembly that is critical to the control of a helicopter. As the FAA 
also has no information pertaining to the quantity of cracked 
components that may currently exist in the U.S. fleet or how quickly 
the condition may propagate to failure, the actions required by this AD 
must be accomplished before further flight for certain helicopters. 
These conditions still exist, therefore, notice and opportunity for 
prior public comment are impracticable and contrary to the public 
interest pursuant to 5 U.S.C. 553(b)(3)(B).
    In addition, the FAA finds that good cause exists pursuant to 5 
U.S.C. 553(d) for making this amendment effective in less than 30 days, 
for the same reasons the FAA found good cause to forego notice and 
comment.

Regulatory Flexibility Act

    The requirements of the Regulatory Flexibility Act (RFA) do not 
apply when an agency finds good cause pursuant to 5 U.S.C. 553 to adopt 
a rule without prior notice and comment. Because the FAA has determined 
that it has good cause to adopt this rule without prior notice and 
comment, RFA analysis is not required.

Costs of Compliance

    The FAA estimates that this AD affects 49 helicopters of U.S. 
Registry. Labor rates are estimated at $85 per work-hour. Based on 
these numbers, the FAA estimates the following costs to comply with 
this AD.
    Inspecting a pilot or co-pilot cyclic stick base takes a minimal 
amount of time for a nominal cost. If required, replacing a pilot 
cyclic stick base takes about 3 work-hours and parts cost about $1,585 
for an estimated cost of $1,840 per helicopter; and replacing a co-
pilot cyclic stick base takes about 1 work-hour and parts cost about 
$711 for an estimated cost of $796 per helicopter.

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

    This AD will not have federalism implications under Executive Order 
13132. This AD will 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 that this AD:
    (1) Is not a ``significant regulatory action'' under Executive 
Order 12866, and
    (2) Will not affect intrastate aviation in Alaska.
