{"abstract":"The FAA proposes to adopt a new airworthiness directive (AD) for certain General Electric Company (GE) Model GEnx-1B64, GEnx-1B64/ P1, GEnx-1B64/P2, GEnx-1B67, GEnx-1B67/P1, GEnx-1B67/P2, GEnx-1B70, GEnx-1B70/75/P1, GEnx-1B70/75/P2, GEnx-1B70/P1, GEnx-1B70/P2, GEnx- 1B70C/P1, GEnx-1B70C/P2, GEnx-1B74/75/P1, GEnx-1B74/75/P2, GEnx-1B76/ P2, GEnx-1B76A/P2, GEnx-2B67, GEnx-2B67B, and GEnx-2B67/P engines. This proposed AD was prompted by a report of a fuel leak caused by a defective fuel tube hose connecting the main fuel-oil heat exchanger. This proposed AD would require removal of all affected fuel tube hoses from service and replacement with parts eligible for installation. 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/2026/03/19/2026-05403.html","cfr_references":[{"chapter":null,"citation_url":null,"part":"39","title":14}],"citation":"91 FR 13238","comment_url":null,"comments_close_on":"2026-05-04","correction_of":null,"corrections":[],"dates":"The FAA must receive comments on this proposed AD by May 4, 2026.","disposition_notes":null,"docket_ids":["Docket No. FAA-2026-2717","Project Identifier AD-2025-01668-E"],"dockets":[{"supporting_documents":[],"agency_name":"FAA","documents":[{"comment_count":9,"comment_start_date":"2026-03-19","updated_at":"2026-05-05T11:56:35.066-04:00","comment_url":"https://www.regulations.gov/commenton/FAA-2026-2717-0001","allow_late_comments":false,"id":"FAA-2026-2717-0001","comment_end_date":"2026-05-05","regulations_dot_gov_open_for_comment":false}],"supporting_documents_count":0,"id":"FAA-2026-2717","title":"AD-2025-01668-E; General Electric GEnx-1B, 2B Engines; Removal of Fuel Tubes from Specific Manufacturing Lots"}],"document_number":"2026-05403","effective_on":null,"end_page":13240,"executive_order_notes":null,"executive_order_number":null,"explanation":null,"full_text_xml_url":"https://www.federalregister.gov/documents/full_text/xml/2026/03/19/2026-05403.xml","html_url":"https://www.federalregister.gov/documents/2026/03/19/2026-05403/airworthiness-directives-general-electric-company-engines","images":{},"images_metadata":{},"json_url":"https://www.federalregister.gov/api/v1/documents/2026-05403?publication_date=2026-03-19","mods_url":"https://www.govinfo.gov/metadata/granule/FR-2026-03-19/2026-05403/mods.xml","not_received_for_publication":null,"page_length":3,"page_views":{"count":397,"last_updated":"2026-05-23 12:15:04 -0400"},"pdf_url":"https://www.govinfo.gov/content/pkg/FR-2026-03-19/pdf/2026-05403.pdf","presidential_document_number":null,"proclamation_number":null,"public_inspection_pdf_url":"https://public-inspection.federalregister.gov/2026-05403.pdf?1773837917","publication_date":"2026-03-19","raw_text_url":"https://www.federalregister.gov/documents/full_text/text/2026/03/19/2026-05403.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":[],"regulatory_plan":{"html_url":"https://www.federalregister.gov/regulations/2120-AA64/airworthiness-directives","title":"Airworthiness Directives"},"comments_count":9,"agency_id":"FAA","comments_url":"https://www.regulations.gov/docketBrowser?rpp=50&so=DESC&sb=postedDate&po=0&dct=PS&D=FAA-2026-2717","supporting_documents_count":0,"docket_id":"FAA-2026-2717","document_id":"FAA-2026-2717-0001","regulation_id_number":"2120-AA64","title":"AD-2025-01668-E; General Electric GEnx-1B, 2B Engines; Removal of Fuel Tubes from Specific Manufacturing Lots","checked_regulationsdotgov_at":"2026-05-06T04:55:04Z"},"regulations_dot_gov_url":null,"significant":false,"signing_date":null,"start_page":13238,"subtype":null,"title":"Airworthiness Directives; General Electric Company Engines","toc_doc":"General Electric Company Engines","toc_subject":"Airworthiness Directives","topics":["Air transportation","Aircraft","Aviation safety","Incorporation by reference","Safety"],"type":"Proposed Rule","volume":91}
