{"abstract":"We are adopting a new airworthiness directive (AD) for the specified Bell Helicopter Textron Canada (BHTC) Model 206A, 206B, 206L, 206L-1, 206L-3, and 206L-4 helicopters. This AD results from mandatory continuing airworthiness information (MCAI) originated by an aviation authority to identify and correct an unsafe condition on an aviation product. The aviation authority of Canada, with which we have a bilateral agreement, states in the MCAI: \"It has been determined that some helicopters have been fitted with a CRES steel fitting, part number (P/N) 407-030-750-103, and the installation of the tailboom attachment bolt does not meet the design criteria.\" We are issuing this AD to require actions that are intended to address the unsafe condition that results from an improper installation of the tailboom attachment bolt in the upper left-hand tailboom attachment CRES steel fitting.","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/2008/07/10/E8-14736.html","cfr_references":[{"chapter":null,"citation_url":null,"part":39,"title":14}],"citation":"73 FR 39577","comment_url":null,"comments_close_on":null,"correction_of":null,"corrections":[],"dates":"This AD becomes effective on August 14, 2008.","disposition_notes":null,"docket_ids":["Docket No. FAA-2008-0040","Directorate Identifier 2007-SW-13-AD","Amendment 39-15598","AD 2008-14-03"],"dockets":[],"document_number":"E8-14736","effective_on":"2008-08-14","end_page":39578,"executive_order_notes":null,"executive_order_number":null,"full_text_xml_url":"https://www.federalregister.gov/documents/full_text/xml/2008/07/10/E8-14736.xml","html_url":"https://www.federalregister.gov/documents/2008/07/10/E8-14736/airworthiness-directives-bell-helicopter-textron-canada-model-206a-206b-206l-206l-1-206l-3-and","images":{},"images_metadata":{},"json_url":"https://www.federalregister.gov/api/v1/documents/E8-14736?publication_date=2008-07-10","mods_url":"https://www.govinfo.gov/metadata/granule/FR-2008-07-10/E8-14736/mods.xml","not_received_for_publication":null,"page_length":2,"page_views":{"count":46,"last_updated":"2026-08-23 22:15:04 -0400"},"pdf_url":"https://www.govinfo.gov/content/pkg/FR-2008-07-10/pdf/E8-14736.pdf","presidential_document_number":null,"proclamation_number":null,"public_inspection_pdf_url":null,"publication_date":"2008-07-10","raw_text_url":"https://www.federalregister.gov/documents/full_text/text/2008/07/10/E8-14736.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":{"checked_regulationsdotgov_at":"2011-11-14T10:46:08Z"},"regulations_dot_gov_url":null,"significant":false,"signing_date":null,"start_page":39577,"subtype":null,"title":"Airworthiness Directives; Bell Helicopter Textron Canada Model 206A, 206B, 206L, 206L-1, 206L-3, and 206L-4 Helicopters","toc_doc":"Bell Helicopter Textron Canada Model 206A, 206B, 206L, 206L-1, 206L-3, and 206L-4 Helicopters","toc_subject":"Airworthiness Directives:","topics":["Air transportation","Aircraft","Aviation safety","Incorporation by reference","Safety"],"type":"Rule","volume":73}
