{"abstract":"We are superseding Airworthiness Directive (AD) 2015-22-02 for certain Bell Helicopter Textron Canada Limited (Bell) Model 429 helicopters. AD 2015-22-02 required inspecting the tail rotor (TR) pitch link assemblies. This AD retains the inspections of AD 2015-22-02 and requires replacing certain pitch link bearings. This AD was prompted by a new design bearing introduced by Bell. We are 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/2019/06/07/2019-11991.html","cfr_references":[{"chapter":null,"citation_url":null,"part":39,"title":14}],"citation":"84 FR 26546","comment_url":null,"comments_close_on":null,"correction_of":null,"corrections":[],"dates":"This AD is effective July 12, 2019.","disposition_notes":null,"docket_ids":["Docket No. FAA-2018-0722","Product Identifier 2017-SW-104-AD","Amendment 39-19651","AD 2019-11-05"],"dockets":[{"supporting_documents":[{"title":"Supporting AD Documents","document_id":"FAA-2018-0722-0003"}],"agency_name":"FAA","documents":[{"comment_count":0,"comment_start_date":"2019-06-07","updated_at":"2023-03-01T14:42:08.171-05:00","comment_url":"https://www.regulations.gov/commenton/FAA-2018-0722-0002","allow_late_comments":null,"id":"FAA-2018-0722-0002","comment_end_date":null,"regulations_dot_gov_open_for_comment":false}],"supporting_documents_count":1,"id":"FAA-2018-0722","title":"Bell Helicopter Textron Canada Limited Model 429 Helicopters, to Require Inspecting Tail Rotor Pitch Link Assemblies and Replacing Certain Pitch Link Bearings.\t2017-SW-104-AD\n\n"}],"document_number":"2019-11991","effective_on":"2019-07-12","end_page":26548,"executive_order_notes":null,"executive_order_number":null,"full_text_xml_url":"https://www.federalregister.gov/documents/full_text/xml/2019/06/07/2019-11991.xml","html_url":"https://www.federalregister.gov/documents/2019/06/07/2019-11991/airworthiness-directives-bell-helicopter-textron-canada-limited-helicopters","images":{},"images_metadata":{},"json_url":"https://www.federalregister.gov/api/v1/documents/2019-11991?publication_date=2019-06-07","mods_url":"https://www.govinfo.gov/metadata/granule/FR-2019-06-07/2019-11991/mods.xml","not_received_for_publication":null,"page_length":3,"page_views":{"count":515,"last_updated":"2026-10-23 14:15:06 -0400"},"pdf_url":"https://www.govinfo.gov/content/pkg/FR-2019-06-07/pdf/2019-11991.pdf","presidential_document_number":null,"proclamation_number":null,"public_inspection_pdf_url":"https://public-inspection.federalregister.gov/2019-11991.pdf?1559825123","publication_date":"2019-06-07","raw_text_url":"https://www.federalregister.gov/documents/full_text/text/2019/06/07/2019-11991.txt","regulation_id_number_info":{"2120-AA64":{"issue":"202410","html_url":"https://www.federalregister.gov/regulations/2120-AA64/airworthiness-directives","title":"Airworthiness Directives","xml_url":"http://www.reginfo.gov/public/do/eAgendaViewRule?pubId=202410&RIN=2120-AA64&operation=OPERATION_EXPORT_XML","priority_category":"Routine and Frequent"}},"regulation_id_numbers":["2120-AA64"],"regulations_dot_gov_info":{"supporting_documents":[{"title":"Supporting AD Documents","document_id":"FAA-2018-0722-0003"}],"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-2018-0722","supporting_documents_count":1,"docket_id":"FAA-2018-0722","document_id":"FAA-2018-0722-0002","regulation_id_number":"2120-AA64","title":"Bell Helicopter Textron Canada Limited Model 429 Helicopters, to Require Inspecting Tail Rotor Pitch Link Assemblies and Replacing Certain Pitch Link Bearings.\t2017-SW-104-AD\n\n","checked_regulationsdotgov_at":"2023-03-01T19:42:07Z"},"regulations_dot_gov_url":null,"significant":false,"signing_date":null,"start_page":26546,"subtype":null,"title":"Airworthiness Directives; Bell Helicopter Textron Canada Limited Helicopters","toc_doc":"Bell Helicopter Textron Canada Limited Helicopters","toc_subject":"Airworthiness Directives:","topics":["Air transportation","Aircraft","Aviation safety","Incorporation by reference","Safety"],"type":"Rule","volume":84}
