{"abstract":"The FAA is revising a notice of proposed rulemaking (NPRM) that applied to certain Bell Helicopter Textron Canada Limited (now Bell Textron Canada Limited) Model 206A, 206B, 206L, 206L-1, 206L-3, and 206L-4 helicopters. This action revises the NPRM by revising the format, rearranging certain paragraphs, converting a certain table to paragraph format, and removing certain language. The FAA is proposing this airworthiness directive (AD) to address the unsafe condition on these products. Since the NPRM was issued, a significant amount of time has elapsed requiring the FAA to reopen the comment period to allow the public a chance to comment on the proposed actions.","action":"Supplemental notice of proposed rulemaking (SNPRM).","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/2021/05/07/2021-08922.html","cfr_references":[{"chapter":null,"citation_url":null,"part":"39","title":14}],"citation":"86 FR 24560","comment_url":null,"comments_close_on":"2021-06-21","correction_of":null,"corrections":[],"dates":"The FAA must receive comments on this SNPRM by June 21, 2021.","disposition_notes":null,"docket_ids":["Docket No. FAA-2010-0865","Project Identifier 2010-SW-061-AD"],"dockets":[{"supporting_documents":[{"title":"Supporting AD Documents","document_id":"FAA-2010-0865-0008"},{"title":"U.S. DOT/FAA -  See Attachments","document_id":"FAA-2010-0865-0003"},{"title":"U.S. DOT/FAA -  See Attachments","document_id":"FAA-2010-0865-0002"}],"agency_name":"FAA","documents":[{"comment_count":1,"comment_start_date":"2021-05-07","updated_at":"2023-02-28T20:27:01.205-05:00","comment_url":"https://www.regulations.gov/commenton/FAA-2010-0865-0005","allow_late_comments":null,"id":"FAA-2010-0865-0005","comment_end_date":"2021-06-22","regulations_dot_gov_open_for_comment":false}],"supporting_documents_count":3,"id":"FAA-2010-0865","title":"Replace Certain Disc Assemblies on Certain Bell 206 Helicopters\r\n"}],"document_number":"2021-08922","effective_on":null,"end_page":24562,"executive_order_notes":null,"executive_order_number":null,"full_text_xml_url":"https://www.federalregister.gov/documents/full_text/xml/2021/05/07/2021-08922.xml","html_url":"https://www.federalregister.gov/documents/2021/05/07/2021-08922/airworthiness-directives-bell-textron-canada-limited-type-certificate-previously-held-by-bell","images":{},"images_metadata":{},"json_url":"https://www.federalregister.gov/api/v1/documents/2021-08922?publication_date=2021-05-07","mods_url":"https://www.govinfo.gov/metadata/granule/FR-2021-05-07/2021-08922/mods.xml","not_received_for_publication":null,"page_length":3,"page_views":{"count":281,"last_updated":"2026-08-23 20:15:04 -0400"},"pdf_url":"https://www.govinfo.gov/content/pkg/FR-2021-05-07/pdf/2021-08922.pdf","presidential_document_number":null,"proclamation_number":null,"public_inspection_pdf_url":"https://public-inspection.federalregister.gov/2021-08922.pdf?1620305117","publication_date":"2021-05-07","raw_text_url":"https://www.federalregister.gov/documents/full_text/text/2021/05/07/2021-08922.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":"Supporting AD Documents","document_id":"FAA-2010-0865-0008"},{"title":"U.S. DOT/FAA -  See Attachments","document_id":"FAA-2010-0865-0003"},{"title":"U.S. DOT/FAA -  See Attachments","document_id":"FAA-2010-0865-0002"}],"regulatory_plan":{"html_url":"https://www.federalregister.gov/regulations/2120-AA64/airworthiness-directives","title":"Airworthiness Directives"},"comments_count":1,"agency_id":"FAA","comments_url":"https://www.regulations.gov/docketBrowser?rpp=50&so=DESC&sb=postedDate&po=0&dct=PS&D=FAA-2010-0865","supporting_documents_count":3,"docket_id":"FAA-2010-0865","document_id":"FAA-2010-0865-0005","regulation_id_number":"2120-AA64","title":"Replace Certain Disc Assemblies on Certain Bell 206 Helicopters\r\n","checked_regulationsdotgov_at":"2023-03-01T01:27:00Z"},"regulations_dot_gov_url":null,"significant":false,"signing_date":null,"start_page":24560,"subtype":null,"title":"Airworthiness Directives; Bell Textron Canada Limited (Type Certificate Previously Held by Bell Helicopter Textron Canada Limited)","toc_doc":"Bell Textron Canada Limited (Type Certificate Previously Held by Bell Helicopter Textron Canada Limited)","toc_subject":"Airworthiness Directives:\n","topics":["Air transportation","Aircraft","Aviation safety","Incorporation by reference","Safety"],"type":"Proposed Rule","volume":86}
