{"abstract":"The FAA proposes to adopt a new airworthiness directive (AD) for all Airbus SAS Model A330-243, A330-243F, A330-341, A330-342, A330- 343, A330-841, and A330-941 airplanes; and Model A340-211, A340-212, A340-213, A340-311, A340-312, A340-313, A340-541, and A340-642 airplanes. This proposed AD was prompted by reports of leaks on closed fuel low pressure shut-off valves (LPSOVs). This proposed AD would require repetitive leak checks of certain fuel LPSOVs and replacement of an affected part if any discrepancy is detected. This proposed AD would also allow the installation of an affected part under certain conditions. The FAA is proposing this AD to address the unsafe condition on these products.","action":"Notice of proposed rulemaking (NPRM).","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/2026/08/13/2026-16567.html","cfr_references":[{"chapter":null,"citation_url":null,"part":"39","title":14}],"citation":"91 FR 52269","comment_url":null,"comments_close_on":"2026-09-28","correction_of":null,"corrections":[],"dates":"The FAA must receive comments on this proposed AD by September 28, 2026.","disposition_notes":null,"docket_ids":["Docket No. FAA-2026-8780","Project Identifier MCAI-2026-00262-T"],"dockets":[{"supporting_documents":[{"title":"U.S. DOT/FAA - Supplemental AD Documents","document_id":"FAA-2026-8780-0005"},{"title":"U.S. DOT/FAA - Supplemental AD Documents","document_id":"FAA-2026-8780-0002"}],"agency_name":"FAA","documents":[{"comment_count":1,"comment_start_date":"2026-08-13","updated_at":"2026-09-29T00:03:19.220-04:00","comment_url":"https://www.regulations.gov/commenton/FAA-2026-8780-0001","allow_late_comments":false,"id":"FAA-2026-8780-0001","comment_end_date":"2026-09-29","regulations_dot_gov_open_for_comment":false}],"supporting_documents_count":2,"id":"FAA-2026-8780","title":"MCAI-2026-00262-T; Airbus SAS Model A330 and A340 airplanes; fuel low pressure shut-off valves"}],"document_number":"2026-16567","effective_on":null,"end_page":52271,"executive_order_notes":null,"executive_order_number":null,"full_text_xml_url":"https://www.federalregister.gov/documents/full_text/xml/2026/08/13/2026-16567.xml","html_url":"https://www.federalregister.gov/documents/2026/08/13/2026-16567/airworthiness-directives-airbus-sas-airplanes","images":{},"images_metadata":{},"json_url":"https://www.federalregister.gov/api/v1/documents/2026-16567?publication_date=2026-08-13","mods_url":"https://www.govinfo.gov/metadata/granule/FR-2026-08-13/2026-16567/mods.xml","not_received_for_publication":null,"page_length":3,"page_views":{"count":160,"last_updated":"2026-10-23 04:15:03 -0400"},"pdf_url":"https://www.govinfo.gov/content/pkg/FR-2026-08-13/pdf/2026-16567.pdf","presidential_document_number":null,"proclamation_number":null,"public_inspection_pdf_url":"https://public-inspection.federalregister.gov/2026-16567.pdf?1786538720","publication_date":"2026-08-13","raw_text_url":"https://www.federalregister.gov/documents/full_text/text/2026/08/13/2026-16567.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-2026-8780-0002"}],"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-2026-8780","supporting_documents_count":1,"docket_id":"FAA-2026-8780","document_id":"FAA-2026-8780-0001","regulation_id_number":"2120-AA64","title":"MCAI-2026-00262-T; Airbus SAS Model A330 and A340 airplanes; fuel low pressure shut-off valves","checked_regulationsdotgov_at":"2026-09-29T04:03:18Z"},"regulations_dot_gov_url":null,"significant":false,"signing_date":null,"start_page":52269,"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":"Proposed Rule","volume":91}
