{"abstract":"The FAA is superseding 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 required 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. This AD was prompted by the engine manufacturer expanding the RPM (N2) steady-state operation avoidance range limits. This AD retains certain requirements of AD 2013-20-13, and requires revising certain sections of the existing RFM for your helicopter and installing or replacing a placard. The FAA is 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/2021/06/10/2021-12040.html","cfr_references":[{"chapter":null,"citation_url":null,"part":"39","title":14}],"citation":"86 FR 30766","comment_url":"https://www.regulations.gov/commenton/FAA-2020-1175-0003","comments_close_on":null,"correction_of":null,"corrections":[],"dates":"This AD is effective July 15, 2021.","disposition_notes":null,"docket_ids":["Docket No. FAA-2020-1175","Product Identifier 2018-SW-071-AD","Amendment 39-21563","AD 2021-11-01"],"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":0,"comment_start_date":"2021-06-10","updated_at":"2024-11-13T18:22:39.764-05:00","comment_url":"https://www.regulations.gov/commenton/FAA-2020-1175-0003","allow_late_comments":true,"id":"FAA-2020-1175-0003","comment_end_date":null,"regulations_dot_gov_open_for_comment":false}],"supporting_documents_count":2,"id":"FAA-2020-1175","title":"2020-NM-XXX-AD"}],"document_number":"2021-12040","effective_on":"2021-07-15","end_page":30768,"executive_order_notes":null,"executive_order_number":null,"full_text_xml_url":"https://www.federalregister.gov/documents/full_text/xml/2021/06/10/2021-12040.xml","html_url":"https://www.federalregister.gov/documents/2021/06/10/2021-12040/airworthiness-directives-bell-textron-canada-limited-helicopters","images":{},"images_metadata":{},"json_url":"https://www.federalregister.gov/api/v1/documents/2021-12040?publication_date=2021-06-10","mods_url":"https://www.govinfo.gov/metadata/granule/FR-2021-06-10/2021-12040/mods.xml","not_received_for_publication":null,"page_length":3,"page_views":{"count":909,"last_updated":"2026-08-25 08:15:04 -0400"},"pdf_url":"https://www.govinfo.gov/content/pkg/FR-2021-06-10/pdf/2021-12040.pdf","presidential_document_number":null,"proclamation_number":null,"public_inspection_pdf_url":"https://public-inspection.federalregister.gov/2021-12040.pdf?1623242724","publication_date":"2021-06-10","raw_text_url":"https://www.federalregister.gov/documents/full_text/text/2021/06/10/2021-12040.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":0,"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-2020-1175-0003","regulation_id_number":"2120-AA64","title":"2020-NM-XXX-AD","checked_regulationsdotgov_at":"2024-11-13T23:31:30Z"},"regulations_dot_gov_url":"https://www.regulations.gov/commenton/FAA-2020-1175-0003","significant":false,"signing_date":null,"start_page":30766,"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":"Rule","volume":86}
