{"abstract":"The FAA is superseding Airworthiness Directive (AD) 2025-07- 06, which applied to all Airbus Helicopters Model H160-B helicopters. AD 2025-07-06 required measuring the axial play of the rotating scissors spherical bearings and depending on the results, accomplishing corrective action and reporting inspection results. Since the FAA issued AD 2025-07-06 a determination was made that repetitive inspections for axial play measurements on non-rotating scissors spherical bearings are necessary. This AD retains all of the actions required in AD 2025-07-06 and extends the definition of an affected part to include all serial numbered non-rotating scissors spherical bearings. This AD also prohibits installing affected rotating and non- rotating scissors spherical bearings unless certain requirements are met. The FAA is issuing this AD to address the unsafe condition on these products.","action":"Final rule; request for comments.","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/2026/02/23/2026-03520.html","cfr_references":[{"chapter":null,"citation_url":null,"part":39,"title":14}],"citation":"91 FR 8371","comment_url":"http://www.regulations.gov/commenton/FAA-2026-0743-0001","comments_close_on":"2026-04-09","correction_of":null,"corrections":[],"dates":"This AD is effective March 10, 2026.","disposition_notes":null,"docket_ids":["Docket No. FAA-2026-0743","Project Identifier MCAI-2025-01764-R","Amendment 39-23257","AD 2026-03-08"],"dockets":[{"supporting_documents":[{"title":"U.S. DOT/FAA - Supplemental AD Documents","document_id":"FAA-2026-0743-0002"}],"agency_name":"FAA","documents":[{"comment_count":0,"comment_start_date":"2026-02-23","updated_at":"2026-02-23T09:57:12.827-05:00","comment_url":"https://www.regulations.gov/commenton/FAA-2026-0743-0001","allow_late_comments":false,"id":"FAA-2026-0743-0001","comment_end_date":"2026-04-10","regulations_dot_gov_open_for_comment":true}],"supporting_documents_count":1,"id":"FAA-2026-0743","title":"MCAI-2025-01764-R; AIRBUS HELICOPTERS H160-B Main Rotor – Scissors Spherical Bearings"}],"document_number":"2026-03520","effective_on":"2026-03-10","end_page":8374,"executive_order_notes":null,"executive_order_number":null,"explanation":null,"full_text_xml_url":"https://www.federalregister.gov/documents/full_text/xml/2026/02/23/2026-03520.xml","html_url":"https://www.federalregister.gov/documents/2026/02/23/2026-03520/airworthiness-directives-airbus-helicopters","images":{},"images_metadata":{},"json_url":"https://www.federalregister.gov/api/v1/documents/2026-03520?publication_date=2026-02-23","mods_url":"https://www.govinfo.gov/metadata/granule/FR-2026-02-23/2026-03520/mods.xml","not_received_for_publication":null,"page_length":4,"page_views":{"count":96,"last_updated":"2026-04-04 12:15:04 -0400"},"pdf_url":"https://www.govinfo.gov/content/pkg/FR-2026-02-23/pdf/2026-03520.pdf","presidential_document_number":null,"proclamation_number":null,"public_inspection_pdf_url":"https://public-inspection.federalregister.gov/2026-03520.pdf?1771595119","publication_date":"2026-02-23","raw_text_url":"https://www.federalregister.gov/documents/full_text/text/2026/02/23/2026-03520.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-2026-0743-0002"}],"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-2026-0743","supporting_documents_count":1,"docket_id":"FAA-2026-0743","document_id":"FAA-2026-0743-0001","regulation_id_number":"2120-AA64","title":"MCAI-2025-01764-R; AIRBUS HELICOPTERS H160-B Main Rotor – Scissors Spherical Bearings","checked_regulationsdotgov_at":"2026-02-24T18:55:04Z"},"regulations_dot_gov_url":"http://www.regulations.gov/commenton/FAA-2026-0743-0001","significant":false,"signing_date":null,"start_page":8371,"subtype":null,"title":"Airworthiness Directives; Airbus Helicopters","toc_doc":"Airbus Helicopters","toc_subject":"Airworthiness Directives","topics":["Air transportation","Aircraft","Aviation safety","Incorporation by reference","Safety"],"type":"Rule","volume":91}
