{"abstract":"The FAA is adopting a new airworthiness directive (AD) for all The Boeing Company Model 777-200, -200LR, -300, -300ER, and 777F series airplanes. This AD was prompted by a report of an overheated alternating current motor pump (ACMP) that caused a fire in the main landing gear (MLG) wheel well. This AD requires a records check or inspection for any installed ACMP with a certain part number and applicable on-condition actions. This AD also prohibits the installation of affected parts. The FAA is issuing this AD to address the unsafe condition on these products.","action":"Final rule.","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/2026/09/28/2026-19751.html","cfr_references":[{"chapter":null,"citation_url":null,"part":"39","title":14}],"citation":"91 FR 61127","comment_url":null,"comments_close_on":null,"correction_of":null,"corrections":[],"dates":"This AD is effective November 2, 2026.","disposition_notes":null,"docket_ids":["Docket No. FAA-2025-3997","Project Identifier AD-2025-01471-T","Amendment 39-23471","AD 2026-19-04"],"dockets":[{"supporting_documents":[{"title":"U.S. DOT/FAA - Supplemental AD Documents","document_id":"FAA-2025-3997-0002"}],"agency_name":"FAA","documents":[{"comment_count":0,"comment_start_date":"2026-09-28","updated_at":"2026-09-28T09:02:35.302-04:00","comment_url":"https://www.regulations.gov/commenton/FAA-2025-3997-0010","allow_late_comments":false,"id":"FAA-2025-3997-0010","comment_end_date":null,"regulations_dot_gov_open_for_comment":false}],"supporting_documents_count":1,"id":"FAA-2025-3997","title":"AD-2025-01471-T; The Boeing Company Model 777 Series airplanes; Alternating Current Motor Pump Inspection"}],"document_number":"2026-19751","effective_on":"2026-11-02","end_page":61133,"executive_order_notes":null,"executive_order_number":null,"full_text_xml_url":"https://www.federalregister.gov/documents/full_text/xml/2026/09/28/2026-19751.xml","html_url":"https://www.federalregister.gov/documents/2026/09/28/2026-19751/airworthiness-directives-the-boeing-company-airplanes","images":{},"images_metadata":{},"json_url":"https://www.federalregister.gov/api/v1/documents/2026-19751?publication_date=2026-09-28","mods_url":"https://www.govinfo.gov/metadata/granule/FR-2026-09-28/2026-19751/mods.xml","not_received_for_publication":null,"page_length":7,"page_views":{"count":232,"last_updated":"2026-10-03 14:15:03 -0400"},"pdf_url":"https://www.govinfo.gov/content/pkg/FR-2026-09-28/pdf/2026-19751.pdf","presidential_document_number":null,"proclamation_number":null,"public_inspection_pdf_url":"https://public-inspection.federalregister.gov/2026-19751.pdf?1790340313","publication_date":"2026-09-28","raw_text_url":"https://www.federalregister.gov/documents/full_text/text/2026/09/28/2026-19751.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-2025-3997-0002"}],"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-2025-3997","supporting_documents_count":1,"docket_id":"FAA-2025-3997","document_id":"FAA-2025-3997-0010","regulation_id_number":"2120-AA64","title":"AD-2025-01471-T; The Boeing Company Model 777 Series airplanes; Alternating Current Motor Pump Inspection","checked_regulationsdotgov_at":"2026-09-29T15:55:04Z"},"regulations_dot_gov_url":null,"significant":false,"signing_date":null,"start_page":61127,"subtype":null,"title":"Airworthiness Directives; The Boeing Company Airplanes","toc_doc":"The Boeing Company Airplanes","toc_subject":"Airworthiness Directives","topics":["Air transportation","Aircraft","Aviation safety","Incorporation by reference","Safety"],"type":"Rule","volume":91}
