{"abstract":"The FAA proposes to adopt a new airworthiness directive (AD) for certain Airbus SAS Model A350-941 and -1041 airplanes. This proposed AD was prompted by reports of deep spot faces on rib 9 at the lower flange bolting with the lower spar. This proposed AD would require a special detailed inspection for discrepancies of certain pylon bolts, and applicable corrective actions, as specified in a European Union Aviation Safety Agency (EASA) AD, which is proposed for incorporation by reference (IBR). 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/2025/04/29/2025-06776.html","cfr_references":[{"chapter":null,"citation_url":null,"part":39,"title":14}],"citation":"90 FR 17749","comment_url":null,"comments_close_on":"2025-06-13","correction_of":null,"corrections":[],"dates":"The FAA must receive comments on this proposed AD by June 13, 2025.","disposition_notes":null,"docket_ids":["Docket No. FAA-2025-0628","Project Identifier MCAI-2024-00728-T"],"dockets":[{"supporting_documents":[{"title":"U.S. DOT/FAA - Supplemental AD Documents","document_id":"FAA-2025-0628-0004"},{"title":"U.S. DOT/FAA - Supplemental AD Document","document_id":"FAA-2025-0628-0002"}],"agency_name":"FAA","documents":[{"comment_count":0,"comment_start_date":"2025-04-29","updated_at":"2025-06-14T00:01:46.316-04:00","comment_url":"https://www.regulations.gov/commenton/FAA-2025-0628-0001","allow_late_comments":false,"id":"FAA-2025-0628-0001","comment_end_date":"2025-06-14","regulations_dot_gov_open_for_comment":false}],"supporting_documents_count":2,"id":"FAA-2025-0628","title":"MCAI-2024-00728-T; Airbus S.A.S.
