{"abstract":"The FAA proposes to adopt a new airworthiness directive (AD) for all Airbus SAS Model A350-941 and -1041 airplanes. This proposed AD was prompted by the obsolescence of the clamp holding in place the oxygen generator in the container and introduction of a new clamp from another manufacturer with different locking torque specifications, which were not properly reflected in Airbus documentation. This proposed AD would require replacing each affected part, would prohibit accomplishing maintenance actions using certain versions of a maintenance procedure task, and would also prohibit the installation of affected parts. 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/2026/02/13/2026-02910.html","cfr_references":[{"chapter":null,"citation_url":null,"part":39,"title":14}],"citation":"91 FR 6801","comment_url":null,"comments_close_on":"2026-03-30","correction_of":null,"corrections":[],"dates":"The FAA must receive comments on this proposed AD by March 30, 2026.","disposition_notes":null,"docket_ids":["Docket No. FAA-2026-1323","Project Identifier MCAI-2025-01190-T"],"dockets":[{"supporting_documents":[{"title":"U.S. DOT/FAA - Supplemental AD Documents","document_id":"FAA-2026-1323-0002"}],"agency_name":"FAA","documents":[{"comment_count":2,"comment_start_date":"2026-02-13","updated_at":"2026-03-31T01:56:25.514-04:00","comment_url":"https://www.regulations.gov/commenton/FAA-2026-1323-0001","allow_late_comments":false,"id":"FAA-2026-1323-0001","comment_end_date":"2026-03-31","regulations_dot_gov_open_for_comment":false}],"supporting_documents_count":1,"id":"FAA-2026-1323","title":"MCAI-2025-01190-T; Airbus SAS Model A350 airplane; revise airworthiness limitations"}],"document_number":"2026-02910","effective_on":null,"end_page":6803,"executive_order_notes":null,"executive_order_number":null,"explanation":null,"full_text_xml_url":"https://www.federalregister.gov/documents/full_text/xml/2026/02/13/2026-02910.xml","html_url":"https://www.federalregister.gov/documents/2026/02/13/2026-02910/airworthiness-directives-airbus-sas-airplanes","images":{},"images_metadata":{},"json_url":"https://www.federalregister.gov/api/v1/documents/2026-02910?publication_date=2026-02-13","mods_url":"https://www.govinfo.gov/metadata/granule/FR-2026-02-13/2026-02910/mods.xml","not_received_for_publication":null,"page_length":3,"page_views":{"count":105,"last_updated":"2026-04-04 00:15:02 -0400"},"pdf_url":"https://www.govinfo.gov/content/pkg/FR-2026-02-13/pdf/2026-02910.pdf","presidential_document_number":null,"proclamation_number":null,"public_inspection_pdf_url":"https://public-inspection.federalregister.gov/2026-02910.pdf?1770903915","publication_date":"2026-02-13","raw_text_url":"https://www.federalregister.gov/documents/full_text/text/2026/02/13/2026-02910.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-2026-1323-0002"}],"regulatory_plan":{"html_url":"https://www.federalregister.gov/regulations/2120-AA64/airworthiness-directives","title":"Airworthiness Directives"},"comments_count":2,"agency_id":"FAA","comments_url":"https://www.regulations.gov/docketBrowser?rpp=50&so=DESC&sb=postedDate&po=0&dct=PS&D=FAA-2026-1323","supporting_documents_count":1,"docket_id":"FAA-2026-1323","document_id":"FAA-2026-1323-0001","regulation_id_number":"2120-AA64","title":"MCAI-2025-01190-T; Airbus SAS Model A350 airplane; revise airworthiness limitations","checked_regulationsdotgov_at":"2026-03-31T21:55:04Z"},"regulations_dot_gov_url":null,"significant":false,"signing_date":null,"start_page":6801,"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}
