{"abstract":"The FAA is adopting a new airworthiness directive (AD) for certain Diamond Aircraft Industries GmbH (DAI) Model DA 42, DA 42 NG, and DA 42 M-NG airplanes. This AD is prompted by mandatory continuing airworthiness information (MCAI) issued by the aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as a loose rudder T-yoke axle nut. This AD requires replacing the rudder T-yoke axle with an improved rudder T-yoke axle. 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/2022/11/09/2022-24370.html","cfr_references":[{"chapter":null,"citation_url":null,"part":39,"title":14}],"citation":"87 FR 67541","comment_url":null,"comments_close_on":null,"correction_of":null,"corrections":[],"dates":"This AD is effective December 14, 2022.","disposition_notes":null,"docket_ids":["Docket No. FAA-2021-1070","Project Identifier 2020-CE-004-AD","Amendment 39-22214","AD 2022-21-15"],"dockets":[{"supporting_documents":[{"title":"U.S. DOT/FAA - Supplemental AD Document (Diamond Aircraft RSB 42-139 and DAI RSB 42NG-081)","document_id":"FAA-2021-1070-0006"},{"title":"Supporting AD Document","document_id":"FAA-2021-1070-0002"}],"agency_name":"FAA","documents":[{"comment_count":0,"comment_start_date":"2022-11-09","updated_at":"2023-02-27T20:00:45.592-05:00","comment_url":"https://www.regulations.gov/commenton/FAA-2021-1070-0005","allow_late_comments":null,"id":"FAA-2021-1070-0005","comment_end_date":null,"regulations_dot_gov_open_for_comment":false}],"supporting_documents_count":2,"id":"FAA-2021-1070","title":"2020-CE-004-AD Diamond Aircraft Industries GmbH Model DA 42, DA 42 NG, and DA 42 M-NG airplanes; Rudder T-yok"}],"document_number":"2022-24370","effective_on":"2022-12-14","end_page":67543,"executive_order_notes":null,"executive_order_number":null,"explanation":null,"full_text_xml_url":"https://www.federalregister.gov/documents/full_text/xml/2022/11/09/2022-24370.xml","html_url":"https://www.federalregister.gov/documents/2022/11/09/2022-24370/airworthiness-directives-diamond-aircraft-industries-gmbh-airplanes","images":{},"images_metadata":{},"json_url":"https://www.federalregister.gov/api/v1/documents/2022-24370?publication_date=2022-11-09","mods_url":"https://www.govinfo.gov/metadata/granule/FR-2022-11-09/2022-24370/mods.xml","not_received_for_publication":null,"page_length":3,"page_views":{"count":698,"last_updated":"2026-04-05 00:15:04 -0400"},"pdf_url":"https://www.govinfo.gov/content/pkg/FR-2022-11-09/pdf/2022-24370.pdf","presidential_document_number":null,"proclamation_number":null,"public_inspection_pdf_url":"https://public-inspection.federalregister.gov/2022-24370.pdf?1667915116","publication_date":"2022-11-09","raw_text_url":"https://www.federalregister.gov/documents/full_text/text/2022/11/09/2022-24370.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":{"supporting_documents":[{"title":"U.S. DOT/FAA - Supplemental AD Document (Diamond Aircraft RSB 42-139 and DAI RSB 42NG-081)","document_id":"FAA-2021-1070-0006"},{"title":"Supporting AD Document","document_id":"FAA-2021-1070-0002"}],"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-2021-1070","supporting_documents_count":2,"docket_id":"FAA-2021-1070","document_id":"FAA-2021-1070-0005","regulation_id_number":"2120-AA64","title":"2020-CE-004-AD Diamond Aircraft Industries GmbH Model DA 42, DA 42 NG, and DA 42 M-NG airplanes; Rudder T-yok","checked_regulationsdotgov_at":"2023-02-28T01:00:44Z"},"regulations_dot_gov_url":null,"significant":false,"signing_date":null,"start_page":67541,"subtype":null,"title":"Airworthiness Directives; Diamond Aircraft Industries GmbH Airplanes","toc_doc":"Diamond Aircraft Industries GmbH Airplanes","toc_subject":"Airworthiness Directives:\n","topics":["Air transportation","Aircraft","Aviation safety","Incorporation by reference","Safety"],"type":"Rule","volume":87}
