{"abstract":"The FAA is superseding Airworthiness Directive (AD) 2024-24-02 for all Safran Helicopter Engines, S.A. (Safran) Model ARRIUS 2F engines. AD 2024-24-02 required removal of the affected fuel control unit (FCU) from service and replacement with a serviceable part. Since the FAA issued AD 2024-24-02, it was determined that certain serial numbers of the affected FCUs are not subject to the unsafe condition. This AD requires removal of the affected FCU from service and replacement with a serviceable part. This AD also reduces the number of affected FCUs. The FAA is issuing this AD to address the unsafe condition on these products.","action":"Final rule.","agencies":[{"raw_name":"DEPARTMENT OF TRANSPORTATION","name":"Transportation Department","id":492,"url":"https://www.federalregister.gov/agencies/transportation-department","json_url":"https://www.federalregister.gov/api/v1/agencies/492","parent_id":null,"slug":"transportation-department"},{"raw_name":"Federal Aviation Administration","name":"Federal Aviation Administration","id":159,"url":"https://www.federalregister.gov/agencies/federal-aviation-administration","json_url":"https://www.federalregister.gov/api/v1/agencies/159","parent_id":492,"slug":"federal-aviation-administration"}],"body_html_url":"https://www.federalregister.gov/documents/full_text/html/2026/04/28/2026-08225.html","cfr_references":[{"chapter":null,"citation_url":null,"part":"39","title":14}],"citation":"91 FR 22710","comment_url":null,"comments_close_on":null,"correction_of":null,"corrections":[],"dates":"This AD is effective June 2, 2026.","disposition_notes":null,"docket_ids":["Docket No. FAA-2026-0016","Project Identifier MCAI-2025-01450-E","Amendment 39-23320","AD 2026-08-12"],"dockets":[{"supporting_documents":[{"title":"U.S. DOT/FAA - Supplemental AD Documents","document_id":"FAA-2026-0016-0002"}],"agency_name":"FAA","documents":[{"comment_count":0,"comment_start_date":"2026-04-28","updated_at":"2026-04-28T10:03:25.679-04:00","comment_url":"https://www.regulations.gov/commenton/FAA-2026-0016-0003","allow_late_comments":false,"id":"FAA-2026-0016-0003","comment_end_date":null,"regulations_dot_gov_open_for_comment":false}],"supporting_documents_count":1,"id":"FAA-2026-0016","title":"MCAI-2025-01450-E; Safran Arrius 2F Engines; Engine Fuel & Control – Fuel Control Unit – Replacement"}],"document_number":"2026-08225","effective_on":"2026-06-02","end_page":22712,"executive_order_notes":null,"executive_order_number":null,"explanation":null,"full_text_xml_url":"https://www.federalregister.gov/documents/full_text/xml/2026/04/28/2026-08225.xml","html_url":"https://www.federalregister.gov/documents/2026/04/28/2026-08225/airworthiness-directives-safran-helicopter-engines-sa-type-certificate-previously-held-by-turbomeca","images":{},"images_metadata":{},"json_url":"https://www.federalregister.gov/api/v1/documents/2026-08225?publication_date=2026-04-28","mods_url":"https://www.govinfo.gov/metadata/granule/FR-2026-04-28/2026-08225/mods.xml","not_received_for_publication":null,"page_length":3,"page_views":{"count":93,"last_updated":"2026-04-30 10:15:05 -0400"},"pdf_url":"https://www.govinfo.gov/content/pkg/FR-2026-04-28/pdf/2026-08225.pdf","presidential_document_number":null,"proclamation_number":null,"public_inspection_pdf_url":"https://public-inspection.federalregister.gov/2026-08225.pdf?1777293913","publication_date":"2026-04-28","raw_text_url":"https://www.federalregister.gov/documents/full_text/text/2026/04/28/2026-08225.txt","regulation_id_number_info":{"2120-AA64":{"issue":"202504","html_url":"https://www.federalregister.gov/regulations/2120-AA64/airworthiness-directives","title":"Airworthiness Directives","xml_url":"http://www.reginfo.gov/public/do/eAgendaViewRule?pubId=202504&RIN=2120-AA64&operation=OPERATION_EXPORT_XML","priority_category":"Routine and Frequent"}},"regulation_id_numbers":["2120-AA64"],"regulations_dot_gov_info":{"supporting_documents":[{"title":"U.S. DOT/FAA - Supplemental AD Documents","document_id":"FAA-2026-0016-0002"}],"regulatory_plan":{"html_url":"https://www.federalregister.gov/regulations/2120-AA64/airworthiness-directives","title":"Airworthiness Directives"},"comments_count":0,"agency_id":"FAA","comments_url":"https://www.regulations.gov/docketBrowser?rpp=50&so=DESC&sb=postedDate&po=0&dct=PS&D=FAA-2026-0016","supporting_documents_count":1,"docket_id":"FAA-2026-0016","document_id":"FAA-2026-0016-0003","regulation_id_number":"2120-AA64","title":"MCAI-2025-01450-E; Safran Arrius 2F Engines; Engine Fuel & Control – Fuel Control Unit – Replacement","checked_regulationsdotgov_at":"2026-04-29T12:55:03Z"},"regulations_dot_gov_url":null,"significant":false,"signing_date":null,"start_page":22710,"subtype":null,"title":"Airworthiness Directives; Safran Helicopter Engines, S.A.
