{"abstract":"The FAA is adopting a new airworthiness directive (AD) for all Airbus SAS Model A350-941 and -1041 airplanes. This AD was prompted by a determination that certain primary flight control actuators have been exposed to mechanical overloads during the acceptance test procedure. This AD requires replacing affected parts with serviceable parts and prohibits the installation of affected parts. 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/2026/06/15/2026-11975.html","cfr_references":[{"chapter":null,"citation_url":null,"part":"39","title":14}],"citation":"91 FR 35881","comment_url":null,"comments_close_on":null,"correction_of":null,"corrections":[],"dates":"This AD is effective July 20, 2026.","disposition_notes":null,"docket_ids":["Docket No. FAA-2026-3473","Project Identifier MCAI-2025-01221-T","Amendment 39-23375","AD 2026-12-05"],"dockets":[{"supporting_documents":[{"title":"U.S. DOT/FAA - Supplemental AD Documents","document_id":"FAA-2026-3473-0005"},{"title":"US DOT/FAA- AD Supplemental Documents","document_id":"FAA-2026-3473-0002"}],"agency_name":"FAA","documents":[{"comment_count":0,"comment_start_date":"2026-06-15","updated_at":"2026-06-15T08:56:52.591-04:00","comment_url":"https://www.regulations.gov/commenton/FAA-2026-3473-0004","allow_late_comments":false,"id":"FAA-2026-3473-0004","comment_end_date":null,"regulations_dot_gov_open_for_comment":false}],"supporting_documents_count":2,"id":"FAA-2026-3473","title":"MCAI-2025-01221-T; Airbus SAS Model A350 airplanes; Primary Flight Control Actuators – Replacement"}],"document_number":"2026-11975","effective_on":"2026-07-20","end_page":35883,"executive_order_notes":null,"executive_order_number":null,"full_text_xml_url":"https://www.federalregister.gov/documents/full_text/xml/2026/06/15/2026-11975.xml","html_url":"https://www.federalregister.gov/documents/2026/06/15/2026-11975/airworthiness-directives-airbus-sas-airplanes","images":{},"images_metadata":{},"json_url":"https://www.federalregister.gov/api/v1/documents/2026-11975?publication_date=2026-06-15","mods_url":"https://www.govinfo.gov/metadata/granule/FR-2026-06-15/2026-11975/mods.xml","not_received_for_publication":null,"page_length":3,"page_views":{"count":110,"last_updated":"2026-06-22 20:15:04 -0400"},"pdf_url":"https://www.govinfo.gov/content/pkg/FR-2026-06-15/pdf/2026-11975.pdf","presidential_document_number":null,"proclamation_number":null,"public_inspection_pdf_url":"https://public-inspection.federalregister.gov/2026-11975.pdf?1781268315","publication_date":"2026-06-15","raw_text_url":"https://www.federalregister.gov/documents/full_text/text/2026/06/15/2026-11975.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-2026-3473-0005"},{"title":"US DOT/FAA- AD Supplemental Documents","document_id":"FAA-2026-3473-0002"}],"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-2026-3473","supporting_documents_count":2,"docket_id":"FAA-2026-3473","document_id":"FAA-2026-3473-0004","regulation_id_number":"2120-AA64","title":"MCAI-2025-01221-T; Airbus SAS Model A350 airplanes; Primary Flight Control Actuators – Replacement","checked_regulationsdotgov_at":"2026-06-16T15:55:04Z"},"regulations_dot_gov_url":null,"significant":false,"signing_date":null,"start_page":35881,"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}
