{"abstract":"The FAA is adopting a new airworthiness directive (AD) for certain Rolls-Royce Deutschland Ltd & Co KG (RRD) Model Trent XWB-97 engines. This AD was prompted by a report of damage to the main fuel hose assembly of the fuel manifold, which resulted an in-flight shut down. This AD requires a one-time set of visual and dimensional inspections of the main fuel hose assembly of the fuel manifold to confirm softness, compliance, and lack of resistance, and for shrinkage, cracks, chafing, dents, kinks, necking, and degradation of the hose braid wire; and, if necessary, replacement of the main fuel hose assembly of the fuel manifold, as specified in a European Union Aviation Safety Agency (EASA) AD, which is incorporated by reference. The FAA is issuing this AD to address the unsafe condition on these products.","action":"Final rule; request for comments.","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/2025/01/31/2025-02031.html","cfr_references":[{"chapter":null,"citation_url":null,"part":39,"title":14}],"citation":"90 FR 8661","comment_url":null,"comments_close_on":null,"correction_of":null,"corrections":[],"dates":"This AD is effective February 18, 2025.","disposition_notes":null,"docket_ids":["Docket No. FAA-2024-2664","Project Identifier MCAI-2024-00518-E","Amendment 39-22912","AD 2024-25-10"],"dockets":[{"supporting_documents":[{"title":"U.S. DOT/FAA - Supplemental AD Documents","document_id":"FAA-2024-2664-0002"}],"agency_name":"FAA","documents":[{"comment_count":1,"comment_start_date":"2025-01-31","updated_at":"2025-03-18T01:56:14.877-04:00","comment_url":"https://www.regulations.gov/commenton/FAA-2024-2664-0001","allow_late_comments":false,"id":"FAA-2024-2664-0001","comment_end_date":"2025-03-18","regulations_dot_gov_open_for_comment":false}],"supporting_documents_count":1,"id":"FAA-2024-2664","title":"MCAI-2024-00518-E; Rolls-Royce Deutschland Ltd & Co KG Model Trent XWB-97 engines; Main Fuel Hose Assembly / Fuel Hoses – Inspection"}],"document_number":"2025-02031","effective_on":"2025-02-18","end_page":8663,"executive_order_notes":null,"executive_order_number":null,"explanation":null,"full_text_xml_url":"https://www.federalregister.gov/documents/full_text/xml/2025/01/31/2025-02031.xml","html_url":"https://www.federalregister.gov/documents/2025/01/31/2025-02031/airworthiness-directives-rolls-royce-deutschland-ltd-and-co-kg-engines","images":{},"images_metadata":{},"json_url":"https://www.federalregister.gov/api/v1/documents/2025-02031?publication_date=2025-01-31","mods_url":"https://www.govinfo.gov/metadata/granule/FR-2025-01-31/2025-02031/mods.xml","not_received_for_publication":null,"page_length":3,"page_views":{"count":168,"last_updated":"2026-04-04 16:15:04 -0400"},"pdf_url":"https://www.govinfo.gov/content/pkg/FR-2025-01-31/pdf/2025-02031.pdf","presidential_document_number":null,"proclamation_number":null,"public_inspection_pdf_url":"https://public-inspection.federalregister.gov/2025-02031.pdf?1738244714","publication_date":"2025-01-31","raw_text_url":"https://www.federalregister.gov/documents/full_text/text/2025/01/31/2025-02031.txt","regulation_id_number_info":{"2120-AA64":{"issue":"202410","html_url":"https://www.federalregister.gov/regulations/2120-AA64/airworthiness-directives","title":"Airworthiness Directives","xml_url":"http://www.reginfo.gov/public/do/eAgendaViewRule?pubId=202410&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-2024-2664-0002"}],"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-2024-2664","supporting_documents_count":1,"docket_id":"FAA-2024-2664","document_id":"FAA-2024-2664-0001","regulation_id_number":"2120-AA64","title":"MCAI-2024-00518-E; Rolls-Royce Deutschland Ltd & Co KG Model Trent XWB-97 engines; Main Fuel Hose Assembly / Fuel Hoses – Inspection","checked_regulationsdotgov_at":"2025-03-19T00:55:03Z"},"regulations_dot_gov_url":null,"significant":false,"signing_date":null,"start_page":8661,"subtype":null,"title":"Airworthiness Directives; Rolls-Royce Deutschland Ltd & Co KG Engines","toc_doc":"Rolls-Royce Deutschland Ltd and Co KG Engines","toc_subject":"Airworthiness Directives","topics":["Air transportation","Aircraft","Aviation safety","Incorporation by reference","Safety"],"type":"Rule","volume":90}
