{"abstract":"The FAA is adopting a new airworthiness directive (AD) for all Airbus Helicopters Model EC120B helicopters. This AD was prompted by a report of geometrical non-conformities in the tail rotor blade (TRB) root section discovered during an accident investigation of a Model EC130B helicopter. Due to the similarity of design and production requirements, certain TRBs for the Model EC120B helicopters were inspected and geometrical non-conformities were also found. This AD requires an inspection (dimensional check) to verify conformity, and replacement of certain TRBs if necessary, as specified in a European Union Aviation Safety Agency (EASA) AD, which is incorporated by reference. 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/2022/02/10/2022-02748.html","cfr_references":[{"chapter":null,"citation_url":null,"part":39,"title":14}],"citation":"87 FR 7705","comment_url":"https://www.regulations.gov/commenton/FAA-2021-0886-0003","comments_close_on":null,"correction_of":null,"corrections":[],"dates":"This AD is effective March 17, 2022.","disposition_notes":null,"docket_ids":["Docket No. FAA-2021-0886","Project Identifier MCAI-2021-00341-R","Amendment 39-21903","AD 2022-02-06"],"dockets":[{"supporting_documents":[{"title":"Supporting AD Document","document_id":"FAA-2021-0886-0002"}],"agency_name":"FAA","documents":[{"comment_count":0,"comment_start_date":"2022-02-10","updated_at":"2024-11-13T18:20:12.710-05:00","comment_url":"https://www.regulations.gov/commenton/FAA-2021-0886-0003","allow_late_comments":true,"id":"FAA-2021-0886-0003","comment_end_date":null,"regulations_dot_gov_open_for_comment":false}],"supporting_documents_count":1,"id":"FAA-2021-0886","title":"2021-NM-XXXX"}],"document_number":"2022-02748","effective_on":"2022-03-17","end_page":7708,"executive_order_notes":null,"executive_order_number":null,"explanation":null,"full_text_xml_url":"https://www.federalregister.gov/documents/full_text/xml/2022/02/10/2022-02748.xml","html_url":"https://www.federalregister.gov/documents/2022/02/10/2022-02748/airworthiness-directives-airbus-helicopters","images":{},"images_metadata":{},"json_url":"https://www.federalregister.gov/api/v1/documents/2022-02748?publication_date=2022-02-10","mods_url":"https://www.govinfo.gov/metadata/granule/FR-2022-02-10/2022-02748/mods.xml","not_received_for_publication":null,"page_length":4,"page_views":{"count":103,"last_updated":"2026-04-04 02:15:03 -0400"},"pdf_url":"https://www.govinfo.gov/content/pkg/FR-2022-02-10/pdf/2022-02748.pdf","presidential_document_number":null,"proclamation_number":null,"public_inspection_pdf_url":"https://public-inspection.federalregister.gov/2022-02748.pdf?1644414318","publication_date":"2022-02-10","raw_text_url":"https://www.federalregister.gov/documents/full_text/text/2022/02/10/2022-02748.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":"Supporting AD Document","document_id":"FAA-2021-0886-0002"}],"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-2021-0886","supporting_documents_count":1,"docket_id":"FAA-2021-0886","document_id":"FAA-2021-0886-0003","regulation_id_number":"2120-AA64","title":"2021-NM-XXXX","checked_regulationsdotgov_at":"2024-11-13T23:20:05Z"},"regulations_dot_gov_url":"https://www.regulations.gov/commenton/FAA-2021-0886-0003","significant":false,"signing_date":null,"start_page":7705,"subtype":null,"title":"Airworthiness Directives; Airbus Helicopters","toc_doc":"Airbus Helicopters","toc_subject":"Airworthiness Directives:\n","topics":["Air transportation","Aircraft","Aviation safety","Incorporation by reference","Safety"],"type":"Rule","volume":87}
