{"abstract":"The FAA is adopting a new airworthiness directive (AD) for certain The Boeing Company Model 787-8, 787-9, and 787-10 airplanes. This AD was prompted by reports of water leakage from the potable water system due to improperly installed waterline couplings, and water leaking into the electronics equipment (EE) bays from above the floor in the main cabin, resulting in water on the equipment in the EE bays. This AD requires an inspection of seat tracks above the EE bays for missing, damaged, or deteriorated sealant, moisture barrier tape, or tape dams, as applicable, and applicable on-condition actions. 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/2025/05/14/2025-08346.html","cfr_references":[{"chapter":null,"citation_url":null,"part":"39","title":14}],"citation":"90 FR 20373","comment_url":null,"comments_close_on":null,"correction_of":null,"corrections":[],"dates":"This AD is effective June 18, 2025.","disposition_notes":null,"docket_ids":["Docket No. FAA-2024-2665","Project Identifier AD-2024-00203-T","Amendment 39-23033","AD 2025-09-12"],"dockets":[{"supporting_documents":[{"title":"U.S. DOT/FAA - Supplemental AD Documents","document_id":"FAA-2024-2665-0002"}],"agency_name":"FAA","documents":[{"comment_count":0,"comment_start_date":"2025-05-14","updated_at":"2025-05-14T10:56:08.826-04:00","comment_url":"https://www.regulations.gov/commenton/FAA-2024-2665-0008","allow_late_comments":false,"id":"FAA-2024-2665-0008","comment_end_date":null,"regulations_dot_gov_open_for_comment":false}],"supporting_documents_count":1,"id":"FAA-2024-2665","title":"AD-2024-00203-T; The Boeing Company Model 787-8, 787-9, and 787-10 airplanes; water waste"}],"document_number":"2025-08346","effective_on":"2025-06-18","end_page":20375,"executive_order_notes":null,"executive_order_number":null,"full_text_xml_url":"https://www.federalregister.gov/documents/full_text/xml/2025/05/14/2025-08346.xml","html_url":"https://www.federalregister.gov/documents/2025/05/14/2025-08346/airworthiness-directives-the-boeing-company-airplanes","images":{},"images_metadata":{},"json_url":"https://www.federalregister.gov/api/v1/documents/2025-08346?publication_date=2025-05-14","mods_url":"https://www.govinfo.gov/metadata/granule/FR-2025-05-14/2025-08346/mods.xml","not_received_for_publication":null,"page_length":3,"page_views":{"count":1677,"last_updated":"2026-06-14 20:15:04 -0400"},"pdf_url":"https://www.govinfo.gov/content/pkg/FR-2025-05-14/pdf/2025-08346.pdf","presidential_document_number":null,"proclamation_number":null,"public_inspection_pdf_url":"https://public-inspection.federalregister.gov/2025-08346.pdf?1747140309","publication_date":"2025-05-14","raw_text_url":"https://www.federalregister.gov/documents/full_text/text/2025/05/14/2025-08346.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-2024-2665-0002"}],"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-2024-2665","supporting_documents_count":1,"docket_id":"FAA-2024-2665","document_id":"FAA-2024-2665-0008","regulation_id_number":"2120-AA64","title":"AD-2024-00203-T; The Boeing Company Model 787-8, 787-9, and 787-10 airplanes; water waste","checked_regulationsdotgov_at":"2025-05-22T21:55:07Z"},"regulations_dot_gov_url":null,"significant":false,"signing_date":null,"start_page":20373,"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":90}
