{"abstract":"The FAA is adopting a new airworthiness directive (AD) for certain Airbus SAS Model A350-941 airplanes. This AD was prompted by a determination that double overcoating sealant was not applied during production on certain fasteners in the center wing box (CWB) and belly faring junction for both left-hand (LH) and right-hand (RH) sides, and certain fasteners are also susceptible to rotation. This AD requires replacing each affected part and applying additional head nut cap protection. 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/2026/06/04/2026-11215.html","cfr_references":[{"chapter":null,"citation_url":null,"part":"39","title":14}],"citation":"91 FR 33593","comment_url":null,"comments_close_on":null,"correction_of":null,"corrections":[],"dates":"This AD is effective July 9, 2026.","disposition_notes":null,"docket_ids":["Docket No. FAA-2026-2280","Project Identifier MCAI-2025-01562-T","Amendment 39-23369","AD 2026-11-08"],"dockets":[],"document_number":"2026-11215","effective_on":"2026-07-09","end_page":33595,"executive_order_notes":null,"executive_order_number":null,"full_text_xml_url":"https://www.federalregister.gov/documents/full_text/xml/2026/06/04/2026-11215.xml","html_url":"https://www.federalregister.gov/documents/2026/06/04/2026-11215/airworthiness-directives-airbus-sas-airplanes","images":{},"images_metadata":{},"json_url":"https://www.federalregister.gov/api/v1/documents/2026-11215?publication_date=2026-06-04","mods_url":"https://www.govinfo.gov/metadata/granule/FR-2026-06-04/2026-11215/mods.xml","not_received_for_publication":null,"page_length":3,"page_views":{"count":81,"last_updated":"2026-06-08 20:15:03 -0400"},"pdf_url":"https://www.govinfo.gov/content/pkg/FR-2026-06-04/pdf/2026-11215.pdf","presidential_document_number":null,"proclamation_number":null,"public_inspection_pdf_url":"https://public-inspection.federalregister.gov/2026-11215.pdf?1780490724","publication_date":"2026-06-04","raw_text_url":"https://www.federalregister.gov/documents/full_text/text/2026/06/04/2026-11215.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":{"checked_regulationsdotgov_at":"2026-06-04T07:47:42Z"},"regulations_dot_gov_url":null,"significant":false,"signing_date":null,"start_page":33593,"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":91}
