[Docket No. FAA-2026-0008; Project Identifier MCAI-2025-01103-R]
RIN 2120-AA64


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 all Airbus Helicopters Model H160-B helicopters. This proposed AD 
was prompted by a report of a leak on a gas cylinder within the 
emergency life raft system (ELRS) container assembly due to geometrical 
gaps between the burst disk and the valve body. This proposed AD would 
require replacing the ELRS container assembly. This proposed AD would 
prohibit installing an affected ELRS container assembly unless certain 
requirements are met. The FAA is proposing this AD to address the 
unsafe condition on these products.

DATES: The FAA must receive comments on this NPRM by February 23, 2026.

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 
Matthew Williams, Aviation Safety Engineer, FAA, 1600 Stewart Avenue, 
Suite 410, Westbury, NY 11590. 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, issued EASA AD 2025-0130, dated June 4, 2025 (EASA AD 
2025-0130), to correct an unsafe condition on Airbus Helicopters Model 
H160-B helicopters. EASA AD 2025-0130 states that an occurrence was 
reported of a leak on a gas cylinder within the ELRS container 
assembly. Subsequent investigation revealed that this leakage was due 
to geometrical gaps between the burst disk and the valve body. This 
condition, if not addressed, could result in the failure of the release 
of the life rafts during an emergency landing on water and consequently 
prevent a timely egress from the helicopter, which could result in 
injury to helicopter occupants.
    EASA AD 2025-0130 specified procedures for replacement of an 
affected ELRS container assembly and prohibited the installation of 
affected ELRS container assembly unless certain requirements are met. 
EASA then revised EASA AD 2025-0130 and issued EASA AD 2025-0130R1, 
dated June 16, 2025 (EASA AD 2025-0130R1) (also referred to as the 
MCAI) to specify that the amendment A or higher identification in the 
definition of

[[Page 930]]

affected ELRS container assembly relates to a gas cylinder and not to 
the ELRS container assembly part number.
    You may examine the MCAI in the AD docket at regulations.gov under 
Docket No. FAA-2026-0008.

Material Incorporated by Reference Under 1 CFR Part 51

    The FAA reviewed EASA AD 2025-0130R1, which specifies procedures to 
replace the ELRS container assembly having Airbus left-hand part number 
(P/N) U256A80A1005 or right-hand P/N U256A80A1006 with a serviceable 
ELRS container assembly and sending an affected ELRS container assembly 
to a Safran Aerosystems repair facility for further corrective actions. 
EASA AD 2025-0130R1 also prohibits installing an affected ELRS 
container assembly on any helicopter unless certain requirements are 
met. 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 civil aviation authority 
(CAA) 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, that authority 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 the same 
type design.

Proposed AD Requirements in This NPRM

    This proposed AD would require accomplishing the actions specified 
in EASA AD 2025-0130R1, described previously, as incorporated by 
reference, except for any differences identified as exceptions in the 
regulatory text of this AD. See ``Differences Between this Proposed AD 
and the MCAI'' for a discussion of the general differences included in 
this AD.

Differences Between This Proposed AD and the MCAI

    The MCAI specifies sending the affected ELRS container assembly to 
a Safran Aerosystems repair facility, whereas this proposed AD would 
allow sending the affected ELRS container assembly to a Safran 
Aerosystems repair facility or an FAA-approved repair facility.

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 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 2025-0130R1 by reference in the FAA final rule. This proposed 
AD would, therefore, require compliance with EASA AD 2025-0130R1 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 2025-0130R1 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 2025-0130R1. Material required by 
EASA AD 2025-0130R1 for compliance will be available at regulations.gov 
under Docket No. FAA-2026-0008 after the FAA final rule is published.

Costs of Compliance

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

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.

facility or an FAA-approved repair facility.
    (4) This AD does not adopt the ``Remarks'' section of EASA AD 
2025-0130R1.

(i) No Reporting Requirement

    Although the material referenced in EASA AD 2025-0130R1 
specifies to submit certain information to the manufacturer, this AD 
does not require this action.

(j) Special Flight Permit

    Special flight permits may be issued in accordance with 14 CFR 
21.197 and 21.199, provided there are no flights over water.

(k) Alternative Methods of Compliance (AMOCs)

    (1) The Manager, International Validation Branch, FAA, has the 
authority to approve AMOCs for this AD, if requested using the 
procedures found in 14 CFR 39.19. In accordance with 14 CFR 39.19,
