{"abstract":"The FAA proposes to adopt a new airworthiness directive (AD) for all Rolls-Royce Deutschland Ltd & Co KG (RRD) Model Trent7000-72 and Trent7000-72C engines. This proposed AD was prompted by reports of engine in-flight shut-downs (IFSDs) caused by the premature failure of certain parts. This proposed AD would prohibit the installation of certain lubrication/scavenge pumps unless certain installation criteria are met. 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/2026/05/20/2026-10076.html","cfr_references":[{"chapter":null,"citation_url":null,"part":"39","title":14}],"citation":"91 FR 29391","comment_url":"http://www.regulations.gov/commenton/FAA-2026-4640-0001","comments_close_on":"2026-07-06","correction_of":null,"corrections":[],"dates":"The FAA must receive comments on this NPRM by July 6, 2026.","disposition_notes":null,"docket_ids":["Docket No. FAA-2026-4640","Project Identifier MCAI-2024-00073-E"],"dockets":[{"supporting_documents":[{"title":"U.S. DOT/FAA - Supplemental AD Documents","document_id":"FAA-2026-4640-0002"}],"agency_name":"FAA","documents":[{"comment_count":0,"comment_start_date":"2026-05-20","updated_at":"2026-05-20T09:56:54.877-04:00","comment_url":"https://www.regulations.gov/commenton/FAA-2026-4640-0001","allow_late_comments":false,"id":"FAA-2026-4640-0001","comment_end_date":"2026-07-07","regulations_dot_gov_open_for_comment":true}],"supporting_documents_count":1,"id":"FAA-2026-4640","title":"2026-NM-XXXX"}],"document_number":"2026-10076","effective_on":null,"end_page":29394,"executive_order_notes":null,"executive_order_number":null,"explanation":null,"full_text_xml_url":"https://www.federalregister.gov/documents/full_text/xml/2026/05/20/2026-10076.xml","html_url":"https://www.federalregister.gov/documents/2026/05/20/2026-10076/airworthiness-directives-rolls-royce-deutschland-ltd-and-co-kg-engines","images":{},"images_metadata":{},"json_url":"https://www.federalregister.gov/api/v1/documents/2026-10076?publication_date=2026-05-20","mods_url":"https://www.govinfo.gov/metadata/granule/FR-2026-05-20/2026-10076/mods.xml","not_received_for_publication":null,"page_length":4,"page_views":{"count":98,"last_updated":"2026-06-01 12:15:06 -0400"},"pdf_url":"https://www.govinfo.gov/content/pkg/FR-2026-05-20/pdf/2026-10076.pdf","presidential_document_number":null,"proclamation_number":null,"public_inspection_pdf_url":"https://public-inspection.federalregister.gov/2026-10076.pdf?1779194711","publication_date":"2026-05-20","raw_text_url":"https://www.federalregister.gov/documents/full_text/text/2026/05/20/2026-10076.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-2026-4640-0002"}],"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-2026-4640","supporting_documents_count":1,"docket_id":"FAA-2026-4640","document_id":"FAA-2026-4640-0001","regulation_id_number":"2120-AA64","title":"2026-NM-XXXX","checked_regulationsdotgov_at":"2026-05-21T11:55:04Z"},"regulations_dot_gov_url":"http://www.regulations.gov/commenton/FAA-2026-4640-0001","significant":false,"signing_date":null,"start_page":29391,"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":"Proposed Rule","volume":91}
