{"abstract":"The FAA proposes to supersede Airworthiness Directive (AD) 2013-20-13 for certain Bell Helicopter Textron Canada Limited (now Bell Textron Canada Limited) (Bell) Model 206B and 206L helicopters. AD 2013-20-13 requires installing a placard beneath the engine power dual tachometer and revising the Operating Limitations section of the existing Rotorcraft Flight Manual (RFM) for your helicopter. Since the FAA issued AD 2013-20-13, the engine manufacturer expanded the RPM (N2) steady-state operation avoidance range limits. This proposed AD would retain certain requirements of AD 2013-20-13, require revising certain sections of the existing RFM for your helicopter, and require either replacing or installing a placard. The actions of this proposed AD are intended to address an 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/2021/03/11/2021-05093.html","cfr_references":[{"chapter":null,"citation_url":null,"part":"39","title":14}],"citation":"86 FR 13828","comment_url":null,"comments_close_on":"2021-04-26","correction_of":null,"corrections":[],"dates":"The FAA must receive comments on this proposed AD by April 26, 2021.","disposition_notes":null,"docket_ids":["Docket No. FAA-2020-1175","Product Identifier 2018-SW-071-AD"],"dockets":[{"supporting_documents":[{"title":"Supporting AD Documents","document_id":"FAA-2020-1175-0004"},{"title":"U.S. DOT/FAA - Supporting AD Document","document_id":"FAA-2020-1175-0002"}],"agency_name":"FAA","documents":[{"comment_count":1,"comment_start_date":"2021-03-11","updated_at":"2023-03-01T00:12:21.315-05:00","comment_url":"https://www.regulations.gov/commenton/FAA-2020-1175-0001","allow_late_comments":null,"id":"FAA-2020-1175-0001","comment_end_date":"2021-04-27","regulations_dot_gov_open_for_comment":false}],"supporting_documents_count":2,"id":"FAA-2020-1175","title":"2020-NM-XXX-AD"}],"document_number":"2021-05093","effective_on":null,"end_page":13830,"executive_order_notes":null,"executive_order_number":null,"full_text_xml_url":"https://www.federalregister.gov/documents/full_text/xml/2021/03/11/2021-05093.xml","html_url":"https://www.federalregister.gov/documents/2021/03/11/2021-05093/airworthiness-directives-bell-textron-canada-limited-helicopters","images":{},"images_metadata":{},"json_url":"https://www.federalregister.gov/api/v1/documents/2021-05093?publication_date=2021-03-11","mods_url":"https://www.govinfo.gov/metadata/granule/FR-2021-03-11/2021-05093/mods.xml","not_received_for_publication":null,"page_length":3,"page_views":{"count":385,"last_updated":"2026-08-25 20:15:03 -0400"},"pdf_url":"https://www.govinfo.gov/content/pkg/FR-2021-03-11/pdf/2021-05093.pdf","presidential_document_number":null,"proclamation_number":null,"public_inspection_pdf_url":"https://public-inspection.federalregister.gov/2021-05093.pdf?1615383933","publication_date":"2021-03-11","raw_text_url":"https://www.federalregister.gov/documents/full_text/text/2021/03/11/2021-05093.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-2020-1175-0004"},{"title":"U.S. DOT/FAA - Supporting AD Document","document_id":"FAA-2020-1175-0002"}],"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-2020-1175","supporting_documents_count":2,"docket_id":"FAA-2020-1175","document_id":"FAA-2020-1175-0001","regulation_id_number":"2120-AA64","title":"2020-NM-XXX-AD","checked_regulationsdotgov_at":"2023-03-01T05:12:20Z"},"regulations_dot_gov_url":null,"significant":false,"signing_date":null,"start_page":13828,"subtype":null,"title":"Airworthiness Directives; Bell Textron Canada Limited Helicopters","toc_doc":"Bell Textron Canada Limited Helicopters","toc_subject":"Airworthiness Directives:\n","topics":["Air transportation","Aircraft","Aviation safety","Incorporation by reference","Safety"],"type":"Proposed Rule","volume":86}
