{"abstract":"The FAA proposes to supersede Airworthiness Directive (AD) 2025-09-03, which applies to certain Bell Textron Canada Limited (Bell) Model 430 helicopters. AD 2025-09-03 reduced the life limits on the main rotor (M/R) clevises, universal bearings, universal to pitch link bolts, the tube assembly, and the rod end assembly and requires replacing the M/R pitch link assemblies with re-identified part numbered assemblies. Since the FAA issued AD 2025-09-03, the FAA received comments proposing changes to the actions of AD 2025-09-03. This proposed AD proposes changes to actions in AD 2025-09-03 and addresses the comments received. The FAA is proposing this AD to address the unsafe condition on these products.","action":"Notice of proposed rulemaking (NPRM).","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/2026/04/07/2026-06690.html","cfr_references":[{"chapter":null,"citation_url":null,"part":"39","title":14}],"citation":"91 FR 17610","comment_url":"http://www.regulations.gov/commenton/FAA-2026-3476-0001","comments_close_on":"2026-05-22","correction_of":null,"corrections":[],"dates":"The FAA must receive comments on this NPRM by May 22, 2026.","disposition_notes":null,"docket_ids":["Docket No. FAA-2026-3476","Project Identifier MCAI-2025-01366-R"],"dockets":[{"supporting_documents":[{"title":"U.S. DOT/FAA - Supplemental AD Documents","document_id":"FAA-2026-3476-0002"}],"agency_name":"FAA","documents":[{"comment_count":0,"comment_start_date":"2026-04-07","updated_at":"2026-04-07T10:57:14.613-04:00","comment_url":"https://www.regulations.gov/commenton/FAA-2026-3476-0001","allow_late_comments":false,"id":"FAA-2026-3476-0001","comment_end_date":"2026-05-23","regulations_dot_gov_open_for_comment":true}],"supporting_documents_count":1,"id":"FAA-2026-3476","title":"2026-NM-XXXX"}],"document_number":"2026-06690","effective_on":null,"end_page":17614,"executive_order_notes":null,"executive_order_number":null,"explanation":null,"full_text_xml_url":"https://www.federalregister.gov/documents/full_text/xml/2026/04/07/2026-06690.xml","html_url":"https://www.federalregister.gov/documents/2026/04/07/2026-06690/airworthiness-directives-bell-textron-canada-limited-helicopters","images":{},"images_metadata":{},"json_url":"https://www.federalregister.gov/api/v1/documents/2026-06690?publication_date=2026-04-07","mods_url":"https://www.govinfo.gov/metadata/granule/FR-2026-04-07/2026-06690/mods.xml","not_received_for_publication":null,"page_length":5,"page_views":{"count":73,"last_updated":"2026-04-07 22:15:04 -0400"},"pdf_url":"https://www.govinfo.gov/content/pkg/FR-2026-04-07/pdf/2026-06690.pdf","presidential_document_number":null,"proclamation_number":null,"public_inspection_pdf_url":"https://public-inspection.federalregister.gov/2026-06690.pdf?1775479510","publication_date":"2026-04-07","raw_text_url":"https://www.federalregister.gov/documents/full_text/text/2026/04/07/2026-06690.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-2026-3476-0002"}],"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-2026-3476","supporting_documents_count":1,"docket_id":"FAA-2026-3476","document_id":"FAA-2026-3476-0001","regulation_id_number":"2120-AA64","title":"2026-NM-XXXX","checked_regulationsdotgov_at":"2026-04-07T17:55:06Z"},"regulations_dot_gov_url":"http://www.regulations.gov/commenton/FAA-2026-3476-0001","significant":false,"signing_date":null,"start_page":17610,"subtype":null,"title":"Airworthiness Directives; Bell Textron Canada Limited Helicopters","toc_doc":"Bell Textron Canada Limited Helicopters","toc_subject":"Airworthiness Directives","topics":["Air transportation","Aircraft","Aviation safety","Incorporation by reference","Safety"],"type":"Proposed Rule","volume":91}
