{"abstract":"We are adopting a new airworthiness directive (AD) for certain Airbus Model A318, A319, A320, and A321 series airplanes; all Model A330-200 Freighter, -200, and -300 series airplanes; and all Model A340-200, -300, -500, and -600 series airplanes. This AD was prompted by reports of false traffic collision avoidance system (TCAS) resolution advisories. This AD requires modifying the software in the TCAS computer processor or replacing the TCAS computer with a new TCAS computer. We are 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/2018/03/26/2018-05013.html","cfr_references":[{"chapter":null,"citation_url":null,"part":39,"title":14}],"citation":"83 FR 12852","comment_url":null,"comments_close_on":null,"correction_of":null,"corrections":[],"dates":"This AD is effective April 30, 2018.","disposition_notes":null,"docket_ids":["Docket No. FAA-2017-1096","Product Identifier 2017-NM-072-AD","Amendment 39-19221","AD 2018-06-01"],"dockets":[{"supporting_documents":[{"title":"Supporting AD Documents","document_id":"FAA-2017-1096-0006"},{"title":"U.S. DOT/FAA - Supporting AD Documents","document_id":"FAA-2017-1096-0003"}],"agency_name":"FAA","documents":[{"comment_count":0,"comment_start_date":"2018-03-26","updated_at":"2023-03-01T14:36:45.590-05:00","comment_url":"https://www.regulations.gov/commenton/FAA-2017-1096-0005","allow_late_comments":null,"id":"FAA-2017-1096-0005","comment_end_date":null,"regulations_dot_gov_open_for_comment":false}],"supporting_documents_count":2,"id":"FAA-2017-1096","title":"2017-NM-072-AD\nAirbus Model A318, A319, A320, and A321 series airplanes; all Model A330-200 Freighter, -200, and -300 series airplanes; and all Model A340-200, -300, -500, and -600 series airplanes"}],"document_number":"2018-05013","effective_on":"2018-04-30","end_page":12856,"executive_order_notes":null,"executive_order_number":null,"explanation":null,"full_text_xml_url":"https://www.federalregister.gov/documents/full_text/xml/2018/03/26/2018-05013.xml","html_url":"https://www.federalregister.gov/documents/2018/03/26/2018-05013/airworthiness-directives-airbus-airplanes","images":{},"images_metadata":{},"json_url":"https://www.federalregister.gov/api/v1/documents/2018-05013?publication_date=2018-03-26","mods_url":"https://www.govinfo.gov/metadata/granule/FR-2018-03-26/2018-05013/mods.xml","not_received_for_publication":null,"page_length":5,"page_views":{"count":302,"last_updated":"2026-04-04 20:15:04 -0400"},"pdf_url":"https://www.govinfo.gov/content/pkg/FR-2018-03-26/pdf/2018-05013.pdf","presidential_document_number":null,"proclamation_number":null,"public_inspection_pdf_url":"https://public-inspection.federalregister.gov/2018-05013.pdf?1521809116","publication_date":"2018-03-26","raw_text_url":"https://www.federalregister.gov/documents/full_text/text/2018/03/26/2018-05013.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 Documents","document_id":"FAA-2017-1096-0006"},{"title":"U.S. DOT/FAA - Supporting AD Documents","document_id":"FAA-2017-1096-0003"}],"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-2017-1096","supporting_documents_count":2,"docket_id":"FAA-2017-1096","document_id":"FAA-2017-1096-0005","regulation_id_number":"2120-AA64","title":"2017-NM-072-AD\nAirbus Model A318, A319, A320, and A321 series airplanes; all Model A330-200 Freighter, -200, and -300 series airplanes; and all Model A340-200, -300, -500, and -600 series airplanes","checked_regulationsdotgov_at":"2023-03-01T19:36:44Z"},"regulations_dot_gov_url":null,"significant":false,"signing_date":null,"start_page":12852,"subtype":null,"title":"Airworthiness Directives; Airbus Airplanes","toc_doc":"Airbus Airplanes","toc_subject":"Airworthiness Directives:","topics":["Air transportation","Aircraft","Aviation safety","Incorporation by reference","Safety"],"type":"Rule","volume":83}
