{"abstract":"The FAA is superseding Airworthiness Directive (AD) 2023-09- 01, which applied to all Airbus SAS Model A318 series airplanes; Model A319 series airplanes; Model A320-211, -212, -214, -216, -231, -232, - 233, -251N, -252N, -253N, -271N, -272N, and -273N airplanes; and Model A321 series airplanes. AD 2023-09-01 was prompted by a report that certain overheat detection system (OHDS) sensing elements installed at certain positions might not properly detect thermal bleed leak events due to a quality escape during the manufacturing process. AD 2023-09-01 required a one-time detailed inspection of each affected part installed at an affected position and replacement if necessary and prohibited the installation of affected parts at affected positions. Since the FAA issued AD 2023-09-01, a new airplane model (A321-253NY) has been certified by EASA, on which affected parts could be installed in service. This AD continues to require the actions in AD 2023-09-01, and revises the applicability to include Model A321-253NY airplanes, 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; 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/2025/01/31/2025-02039.html","cfr_references":[{"chapter":null,"citation_url":null,"part":"39","title":14}],"citation":"90 FR 8667","comment_url":null,"comments_close_on":null,"correction_of":null,"corrections":[],"dates":"This AD is effective February 18, 2025.","disposition_notes":null,"docket_ids":["Docket No. FAA-2024-2715","Project Identifier MCAI-2024-00621-T","Amendment 39-22919","AD 2024-26-04"],"dockets":[{"supporting_documents":[{"title":"U.S. DOT/FAA - Supplemental AD Documents","document_id":"FAA-2024-2715-0003"}],"agency_name":"FAA","documents":[{"comment_count":1,"comment_start_date":"2025-01-31","updated_at":"2025-03-18T01:56:18.444-04:00","comment_url":"https://www.regulations.gov/commenton/FAA-2024-2715-0001","allow_late_comments":false,"id":"FAA-2024-2715-0001","comment_end_date":"2025-03-18","regulations_dot_gov_open_for_comment":false}],"supporting_documents_count":1,"id":"FAA-2024-2715","title":"MCAI-2024-00621-T; Airbus SAS Model A318, A319, A320 and A321 series airplanes; overheat detection system (OHDS) sensing elements"}],"document_number":"2025-02039","effective_on":"2025-02-18","end_page":8670,"executive_order_notes":null,"executive_order_number":null,"full_text_xml_url":"https://www.federalregister.gov/documents/full_text/xml/2025/01/31/2025-02039.xml","html_url":"https://www.federalregister.gov/documents/2025/01/31/2025-02039/airworthiness-directives-airbus-sas-airplanes","images":{},"images_metadata":{},"json_url":"https://www.federalregister.gov/api/v1/documents/2025-02039?publication_date=2025-01-31","mods_url":"https://www.govinfo.gov/metadata/granule/FR-2025-01-31/2025-02039/mods.xml","not_received_for_publication":null,"page_length":4,"page_views":{"count":232,"last_updated":"2026-08-25 12:15:05 -0400"},"pdf_url":"https://www.govinfo.gov/content/pkg/FR-2025-01-31/pdf/2025-02039.pdf","presidential_document_number":null,"proclamation_number":null,"public_inspection_pdf_url":"https://public-inspection.federalregister.gov/2025-02039.pdf?1738244714","publication_date":"2025-01-31","raw_text_url":"https://www.federalregister.gov/documents/full_text/text/2025/01/31/2025-02039.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-2024-2715-0003"}],"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-2024-2715","supporting_documents_count":1,"docket_id":"FAA-2024-2715","document_id":"FAA-2024-2715-0001","regulation_id_number":"2120-AA64","title":"MCAI-2024-00621-T; Airbus SAS Model A318, A319, A320 and A321 series airplanes; overheat detection system (OHDS) sensing elements","checked_regulationsdotgov_at":"2025-03-19T00:55:03Z"},"regulations_dot_gov_url":null,"significant":false,"signing_date":null,"start_page":8667,"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}
