{"abstract":"The FAA is adopting a new airworthiness directive (AD) for all Airbus SAS Model A321-271NY airplanes. This AD was prompted by the determination that affected parts addressed by other ADs could be installed in service on this airplane model. This AD requires corrective action if necessary and prohibits the installation of affected parts. The FAA is issuing this AD to address unsafe conditions on these products.","action":"Final rule; request for comments.","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/2025/08/18/2025-15687.html","cfr_references":[{"chapter":null,"citation_url":null,"part":39,"title":14}],"citation":"90 FR 40035","comment_url":null,"comments_close_on":null,"correction_of":null,"corrections":[],"dates":"This AD is effective September 2, 2025.","disposition_notes":null,"docket_ids":["Docket No. FAA-2025-1731","Project Identifier MCAI-2025-00491-T","Amendment 39-23109","AD 2025-16-11"],"dockets":[{"supporting_documents":[{"title":"U.S. DOT/FAA - Supplemental AD Documents","document_id":"FAA-2025-1731-0002"}],"agency_name":"FAA","documents":[{"comment_count":1,"comment_start_date":"2025-08-18","updated_at":"2025-10-03T00:04:14.517-04:00","comment_url":"https://www.regulations.gov/commenton/FAA-2025-1731-0001","allow_late_comments":false,"id":"FAA-2025-1731-0001","comment_end_date":"2025-10-03","regulations_dot_gov_open_for_comment":false}],"supporting_documents_count":1,"id":"FAA-2025-1731","title":"MCAI-2025-00491-T; Airbus SAS Model A321-271NY airplanes; prohibit installation of affected parts"}],"document_number":"2025-15687","effective_on":"2025-09-02","end_page":40037,"executive_order_notes":null,"executive_order_number":null,"explanation":null,"full_text_xml_url":"https://www.federalregister.gov/documents/full_text/xml/2025/08/18/2025-15687.xml","html_url":"https://www.federalregister.gov/documents/2025/08/18/2025-15687/airworthiness-directives-airbus-sas-airplanes","images":{},"images_metadata":{},"json_url":"https://www.federalregister.gov/api/v1/documents/2025-15687?publication_date=2025-08-18","mods_url":"https://www.govinfo.gov/metadata/granule/FR-2025-08-18/2025-15687/mods.xml","not_received_for_publication":null,"page_length":3,"page_views":{"count":96,"last_updated":"2026-04-04 16:15:04 -0400"},"pdf_url":"https://www.govinfo.gov/content/pkg/FR-2025-08-18/pdf/2025-15687.pdf","presidential_document_number":null,"proclamation_number":null,"public_inspection_pdf_url":"https://public-inspection.federalregister.gov/2025-15687.pdf?1755261926","publication_date":"2025-08-18","raw_text_url":"https://www.federalregister.gov/documents/full_text/text/2025/08/18/2025-15687.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-2025-1731-0002"}],"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-2025-1731","supporting_documents_count":1,"docket_id":"FAA-2025-1731","document_id":"FAA-2025-1731-0001","regulation_id_number":"2120-AA64","title":"MCAI-2025-00491-T; Airbus SAS Model A321-271NY airplanes; prohibit installation of affected parts","checked_regulationsdotgov_at":"2025-10-03T08:55:03Z"},"regulations_dot_gov_url":null,"significant":false,"signing_date":null,"start_page":40035,"subtype":null,"title":"Airworthiness Directives; Airbus SAS Airplanes","toc_doc":"Airbus SAS Airplanes","toc_subject":"Airworthiness Directives","topics":["Air transportation","Aircraft","Aviation safety","Incorporation by reference","Safety"],"type":"Rule","volume":90}
