{"abstract":"The FAA proposes to adopt a new airworthiness directive (AD) for all Bell Textron Canada Limited Model 206A, 206A-1 (OH-58A), 206B, 206B-1, 206L, 206L-1, 206L-3, and 206L-4 helicopters. This proposed AD was prompted by a loss of tail rotor (TR) drive due to a failure of an adhesively bonded joint between an adapter and a tube on one of the segmented TR drive shaft (TRDS) assemblies. This proposed AD would require determining if an affected TRDS is installed; repetitively inspecting the bond line for damage; repetitively performing a proof load test of the TRDS assembly; and depending on the results of the inspections or the proof load tests, removing an affected TRDS from service and replacing it with a serviceable TRDS. This proposed AD would also prohibit installing a TRDS unless it meets certain requirements, as specified in a Transport Canada AD, which is proposed for incorporation by reference. 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/2022/11/28/2022-25709.html","cfr_references":[{"chapter":null,"citation_url":null,"part":"39","title":14}],"citation":"87 FR 72899","comment_url":null,"comments_close_on":"2023-01-12","correction_of":null,"corrections":[],"dates":"The FAA must receive comments on this proposed AD by January 12, 2023.","disposition_notes":null,"docket_ids":["Docket No. FAA-2022-1488","Project Identifier MCAI-2022-00788-R"],"dockets":[{"supporting_documents":[{"title":"U.S. DOT/FAA - Supplemental AD Documents","document_id":"FAA-2022-1488-0005"},{"title":"AD Supporting Document","document_id":"FAA-2022-1488-0002"}],"agency_name":"FAA","documents":[{"comment_count":1,"comment_start_date":"2022-11-28","updated_at":"2023-02-27T19:55:15.663-05:00","comment_url":"https://www.regulations.gov/commenton/FAA-2022-1488-0001","allow_late_comments":null,"id":"FAA-2022-1488-0001","comment_end_date":"2023-01-13","regulations_dot_gov_open_for_comment":false}],"supporting_documents_count":2,"id":"FAA-2022-1488","title":"MCAI-2022-00788-R TCCA IBR AD - Bell Textron Canada Helicopters"}],"document_number":"2022-25709","effective_on":null,"end_page":72902,"executive_order_notes":null,"executive_order_number":null,"full_text_xml_url":"https://www.federalregister.gov/documents/full_text/xml/2022/11/28/2022-25709.xml","html_url":"https://www.federalregister.gov/documents/2022/11/28/2022-25709/airworthiness-directives-bell-textron-canada-limited-helicopters","images":{},"images_metadata":{},"json_url":"https://www.federalregister.gov/api/v1/documents/2022-25709?publication_date=2022-11-28","mods_url":"https://www.govinfo.gov/metadata/granule/FR-2022-11-28/2022-25709/mods.xml","not_received_for_publication":null,"page_length":4,"page_views":{"count":450,"last_updated":"2026-08-26 10:15:07 -0400"},"pdf_url":"https://www.govinfo.gov/content/pkg/FR-2022-11-28/pdf/2022-25709.pdf","presidential_document_number":null,"proclamation_number":null,"public_inspection_pdf_url":"https://public-inspection.federalregister.gov/2022-25709.pdf?1669383930","publication_date":"2022-11-28","raw_text_url":"https://www.federalregister.gov/documents/full_text/text/2022/11/28/2022-25709.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-2022-1488-0005"},{"title":"AD Supporting Document","document_id":"FAA-2022-1488-0002"}],"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-2022-1488","supporting_documents_count":2,"docket_id":"FAA-2022-1488","document_id":"FAA-2022-1488-0001","regulation_id_number":"2120-AA64","title":"MCAI-2022-00788-R TCCA IBR AD - Bell Textron Canada Helicopters","checked_regulationsdotgov_at":"2023-02-28T00:55:14Z"},"regulations_dot_gov_url":null,"significant":false,"signing_date":null,"start_page":72899,"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":87}
