Any commentary that the FAA receives which is not specifically designated as CBI will be placed in the public docket for this rulemaking. Background EASA, which is the Technical Agent for the Member States of the European Union, has issued EASA AD 2023–0002, dated January 5, 2023 (EASA AD 2023– 0002) (also referred to as the MCAI), to correct an unsafe condition on Airbus Helicopters Model SA 341 G and SA 342 J (Gazelle) helicopters if equipped with a pilot collective pitch stick having part number (P/N) 341A27–5041–0057, P/N 341A27–5041–0058, P/N 341A27– 5041–0060, P/N 341A27–5041–0063, P/ N 341A27–5041–0064, P/N 341A27– 5041–0066, P/N 341A27–5041–0067, or P/N 341A27–5041–0068. The MCAI states that a pilot collective pitch stick handle grip broke into two pieces when a maintenance technician pulled the handle grip during helicopter maintenance. According to the MCAI, following investigation and analysis, the handle grip material (Rilsan) is sensitive to aging, with consequent degradation of the structural strength of the handle grip. The FAA is proposing this AD to prevent failure of the handle grip, which if not addressed, could result in reduced integrity of the flight control system and subsequent loss of control of the helicopter. PO 00000 Frm 00013 Fmt 4702 Sfmt 4702 FAA’s Determination These products have been approved by the aviation authority of another country and are 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 referenced 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 these same type designs. Proposed AD Requirements in This NPRM This proposed AD would require accomplishing the actions specified in EASA AD 2023–0002, 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 NPRM and the MCAI.’’ 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, the FAA proposes to incorporate EASA AD 2023–0002 by reference in the FAA final rule. This proposed AD would, therefore, require compliance with EASA AD 2023–0002 in its entirety through that incorporation, except for any differences identified as exceptions in the E:\FR\FM\29NOP1.SGM 29NOP1 94628 Federal Register / Vol. 89, No. 230 / Friday, November 29, 2024 / Proposed Rules regulatory text of this proposed AD. Using common terms that are the same as the heading of a particular section in EASA AD 2023–0002 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 2023–0002. Material referenced in EASA AD 2023– 0002 for compliance will be available at regulations.gov under Docket No. FAA– 2024–2541 after the FAA final rule is published. Differences Between This NPRM and the MCAI The MCAI requires using Airbus Helicopters ASB SA341 67.06 and ASB SA342 67.06 (co-published as one document and referred to as ASB No. ‘‘GAZ–67.06’’), Revision 0, dated June 15, 2022, for compliance, and allows using future revisions of that material, whereas this proposed AD would instead require using Airbus Helicopters ASB No. GAZ–67.06, Revision 1, dated November 2, 2022, and allows using future revisions of that material as specified in the Ref. Publications section of EASA AD 2023–0002, which is proposed for incorporation. Costs of Compliance The FAA estimates that this AD, if adopted as proposed, would affect 16 helicopters of U.S. registry. Replacing the collective pitch handle grip would take 4 work-hours and parts would cost $230 for an estimated cost of $570 per helicopter and $9,120 for the U.S. fleet. khammond on DSK9W7S144PROD with PROPOSALS 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 16:47 Nov 27, 2024 Jkt 265001 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. The authority citation for part 39 continues to read as follows: ■ Authority: 49 U.S.C. 106(g), 40113, 44701. § 39.13 [Amended] 2. The FAA amends § 39.13 by adding the following new airworthiness directive: ■ Airbus Helicopters: Docket No. FAA–2024– 2541; Project Identifier MCAI–2023– 00006–R.

Airworthiness Directives; Airbus Helicopters

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 Airbus Helicopters Model SA341G and SA342J helicopters. 
This proposed AD was prompted by a report of a pilot collective pitch 
stick handle grip that broke when pulled. This proposed AD would 
require replacing certain pilot collective pitch stick handle grips and 
prohibit installing those pilot collective pitch stick handle grips. 
These actions are specified in a European Union Aviation Safety Agency 
(EASA) AD, which is proposed for incorporation by reference. The FAA is 
proposing this AD to address the unsafe condition on these products.

not specifically designated as CBI will be placed in the public docket 
for this rulemaking.

Background

    EASA, which is the Technical Agent for the Member States of the 
European Union, has issued EASA AD 2023-0002, dated January 5, 2023 
(EASA AD 2023-0002) (also referred to as the MCAI), to correct an 
unsafe condition on Airbus Helicopters Model SA 341 G and SA 342 J 
(Gazelle) helicopters if equipped with a pilot collective pitch stick 
having part number (P/N) 341A27-5041-0057, P/N 341A27-5041-0058, P/N 
341A27-5041-0060, P/N 341A27-5041-0063, P/N 341A27-5041-0064, P/N 
341A27-5041-0066, P/N 341A27-5041-0067, or P/N 341A27-5041-0068. The 
MCAI states that a pilot collective pitch stick handle grip broke into 
two pieces when a maintenance technician pulled the handle grip during 
helicopter maintenance. According to the MCAI, following investigation 
and analysis, the handle grip material (Rilsan) is sensitive to aging, 
with consequent degradation of the structural strength of the handle 
grip.
    The FAA is proposing this AD to prevent failure of the handle grip, 
which if not addressed, could result in reduced integrity of the flight 
control system and subsequent loss of control of the helicopter.
    You may examine the MCAI in the AD docket at regulations.gov under 
Docket No. FAA-2024-2541.

Material Incorporated by Reference Under 1 CFR Part 51

    EASA AD 2023-0002 requires replacing handle grips P/N 41A27-1377-00 
installed on pilot collective pitch sticks before June 15, 2022, and 
replacing certain part-numbered pilot collective pitch sticks complete 
with a handle grip. EASA AD 2023-0002 also prohibits installing the 
affected handle grips and pilot collective pitch sticks equipped with 
an affected handle grip on any helicopter. 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 products have been approved by the aviation authority of 
another country and are 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 referenced 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 these same type designs.

Proposed AD Requirements in This NPRM

    This proposed AD would require accomplishing the actions specified 
in EASA AD 2023-0002, 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 NPRM and the MCAI.''

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, the 
FAA proposes to incorporate EASA AD 2023-0002 by reference in the FAA 
final rule. This proposed AD would, therefore, require compliance with 
EASA AD 2023-0002 in its entirety through that incorporation, except 
for any differences identified as exceptions in the

[[Page 94628]]

regulatory text of this proposed AD. Using common terms that are the 
same as the heading of a particular section in EASA AD 2023-0002 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 2023-0002. Material referenced in EASA AD 2023-0002 for 
compliance will be available at regulations.gov under Docket No. FAA-
2024-2541 after the FAA final rule is published.

Differences Between This NPRM and the MCAI

    The MCAI requires using Airbus Helicopters ASB SA341 67.06 and ASB 
SA342 67.06 (co-published as one document and referred to as ASB No. 
``GAZ-67.06''), Revision 0, dated June 15, 2022, for compliance, and 
allows using future revisions of that material, whereas this proposed 
AD would instead require using Airbus Helicopters ASB No. GAZ-67.06, 
Revision 1, dated November 2, 2022, and allows using future revisions 
of that material as specified in the Ref. Publications section of EASA 
AD 2023-0002, which is proposed for incorporation.

Costs of Compliance

    The FAA estimates that this AD, if adopted as proposed, would 
affect 16 helicopters of U.S. registry.
    Replacing the collective pitch handle grip would take 4 work-hours 
and parts would cost $230 for an estimated cost of $570 per helicopter 
and $9,120 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.
