# [Amended]
**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 reports of a fully discharged personal locator beacon (PLB) battery installed on an emergency life-raft system (ELRS), as well as a report where the ropes connecting the two ELRS to the PLB were not correctly attached. This proposed AD would require performing a functional test of the PLB and inspecting the rope connection to the ELRS. Depending on the results of the functional test, this proposed AD would require performing the functional test again or replacing affected parts, and depending on the results of the rope inspection, correctly attaching the wrist strap of the PLB to the ELRS rope. This proposed AD would also prohibit the installation of a certain part-numbered PLB and the rope connection to the ELRS, 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 April 9, 2026.

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 Steven Warwick, 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, has issued EASA AD 2025-0162, dated July 29, 2025 (EASA AD 2025-0162) (also referred to as the MCAI), to correct an unsafe condition on Airbus Helicopters Model H160-B helicopters. The MCAI states there have been reports of a fully discharged PLB battery that is installed on the ELRS. The MCAI further states an occurrence was reported where the connecting rope between the two ELRS and the PLB was not attached correctly. The FAA is proposing this AD to prevent operational failure of the PLB. The unsafe condition, if not addressed, could result in delayed arrival of the rescue services and timely medical assistance to injured crew members or passengers during an emergency use of the life-raft.
You may examine the MCAI in the AD docket at *regulations.gov* under Docket No. FAA-2026-1337.
**Material Incorporated by Reference Under 1 CFR Part 51**
The FAA reviewed EASA AD 2025-0162, which specifies procedures for inspecting PLB part number (P/N) U256M30T1001, with manufacturer P/N 500-32-2Y-H and the connecting rope between the PLB and the ELRS and, depending on the results of this inspection, performing a functional test up to five times or replacing the PLB battery pack with a new battery pack; and if necessary, correctly connecting the rope attached to the ELRS. EASA AD 2025-0162 also prohibits installing an affected PLB or the rope between an affected PLB and ELRS 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 2025-0162, described previously, except for any differences identified as exceptions in the regulatory text of this proposed 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 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 2025-0162 is incorporated by reference in this AD. This AD requires compliance with EASA AD 2025-0162 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 2025-0162 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 2025-0162. Material required by EASA AD 2025-0162 for compliance will be available at *regulations.gov* under Docket No. FAA-2026-1337 after this AD is published.
**Costs of Compliance**
The FAA estimates that this AD, if adopted as proposed, would affect 12 helicopters of U.S. registry.
The FAA estimates the following costs to comply with this proposed AD:
| Action | Labor cost | Parts cost | Cost per | Cost on U.S. |
| --- | --- | --- | --- | --- |
| Perform functional test of each PLB | 1 work-hours × $85 per hour = $85 | $0 | $85 | $1,020 |
| Inspect the wrist strap | 1 work-hour × $85 per hour = $85 | 0 | 85 | 1,020 |
The FAA estimates the following costs to do any replacements or corrections that would be required based on the results of the proposed inspection. The agency has no way of determining the number of helicopters that might need these replacements or corrections.
| Action | Labor cost | Parts cost | Cost per product |
| --- | --- | --- | --- |
| Replace battery pack | 1 work-hours × $85 per hour = $85 | $2,173 | $2,258 |
| Replace a PLB | 1 work-hours × $85 per hour = $85 | 5,393 | 5,478 |
| Attach wrist strap correctly | 1 work-hour × $85 per hour = $85 | 0 | 85 |
**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**
