This AD was prompted by a determination of a possible interference of the hoist operator's helmet cord with the toggle switch of the hoist cable cut control. This AD requires replacing, or modifying and re-identifying, certain hoist shear toggle switch supports, and prohibits installing certain hoist shear toggle switch supports, as specified in a European Union Aviation Safety Agency (EASA) AD, which is incorporated by reference. The FAA is issuing this AD to address the unsafe condition on these products. </SUM> <EFFDATE> <HD SOURCE="HED">DATES:</HD> This AD is effective April 21, 2025. The Director of the Federal Register approved the incorporation by reference of a certain publication listed in this AD as of April 21, 2025. The FAA must receive comments on this AD by May 19, 2025. </EFFDATE> <HD SOURCE="HED">ADDRESSES:</HD> You may send comments, using the procedures found in 14 CFR 11.43 and 11.45, by any of the following methods: • <E T="03">Federal eRulemaking Portal:</E> Go to <E T="03">regulations.gov</E> .

Send your comments to an address listed under the <E T="02">ADDRESSES</E> section. Include “Docket No. FAA-2025-0337; Project Identifier MCAI-2023-01016-R” at the beginning of your comments. The most helpful comments reference a specific portion of the final rule, explain the reason for any recommended change, and include supporting data. The FAA will consider all comments received by the closing date and may amend this final rule because of those comments. Except for Confidential Business Information (CBI) as described in the following paragraph, and other information as described in 14 CFR 11.35, the FAA will post all comments received, without change, to <E T="03">regulations.gov</E> , including any personal information you provide. The agency will also post a report summarizing each substantive verbal contact received about this final rule. <HD SOURCE="HD1">Confidential Business Information</HD> CBI is commercial or financial information that is both customarily 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 AD 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 AD, 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 AD. Submissions containing CBI should be sent to Evan Weaver, Aviation Safety Engineer, FAA, 1600 Stewart Avenue, Suite 410, Westbury, NY 11590; phone: (817) 521-5771; email: <E T="03">evan.p.weaver@faa.gov.</E> Any commentary that the FAA receives which is not specifically designated as CBI will be placed in the public docket for this rulemaking. <HD SOURCE="HD1">Background</HD> EASA, which is the Technical Agent for the Member States of the European Union, has issued EASA AD 2023-0172, dated September 20, 2023 (EASA AD 2023-0172) (also referred to as the MCAI), to correct an unsafe condition on Airbus Helicopters Model AS 332 L1 helicopters, serial numbers (S/Ns) 2218, 2221, 2341, 2950, and 2956; and Model EC 225 LP helicopters, S/Ns 2666, 2673, and 2759. The MCAI states it was determined that the hoist operator's helmet cord can entangle with the toggle switch of the hoist cable cut control, which is located on the cabin wall in front of the right-hand main sliding door. The MCAI further states this condition could lead to unintentional activation of the hoist cable cutter during a hoist operation, which could lead to an in-flight release of the hoisted external load. The FAA is issuing this AD to address the unsafe condition on these products. You may examine the MCAI in the AD docket at <E T="03">regulations.gov</E> under Docket No. FAA-2025-0337. <HD SOURCE="HD1">Material Incorporated by Reference Under 1 CFR Part 51</HD> The FAA reviewed EASA AD 2023-0172, which requires, for Model AS 332 L1 helicopters, replacing an affected hoist shear toggle switch support with a serviceable hoist shear toggle switch support, and for Model EC 225 LP helicopters, modifying and re-identifying an affected hoist shear toggle switch support. After replacement or modification and re-identification, as applicable, EASA AD 2023-0172 also prohibits installing an affected part as defined within 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 <E T="02">ADDRESSES</E> section. <HD SOURCE="HD1">FAA's Determination</HD> 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 AD after determining that the unsafe condition described previously is likely to exist or develop on other products of the same type design. <HD SOURCE="HD1">AD Requirements</HD> This AD requires accomplishing the actions specified in EASA AD 2023-0172, described previously, as incorporated by reference, except for any differences identified as exceptions in the regulatory text of this AD. <HD SOURCE="HD1">Explanation of Required Compliance Information</HD> 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 2023-0172 is incorporated by reference in this AD. This AD requires compliance with EASA AD 2023-0172 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 2023-0172 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 2023-0172. Material required by EASA AD 2023-0172 for compliance will be available at <E T="03">regulations.gov</E> under Docket No. FAA-2025-0337 after this AD is published. <HD SOURCE="HD1">Justification for Immediate Adoption and Determination of the Effective Date</HD> Section 553(b) of the Administrative Procedure Act (APA) (5 U.S.C. 551 <E T="03">et seq.</E> ) 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 pri ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ Preview showing 10k of 18k characters.
