{"abstract":"The FAA proposes to adopt a new airworthiness directive (AD) for certain The Boeing Company Model 747-400F series airplanes. This proposed AD was prompted by a report that cap seals were not applied to certain fasteners in the fuel tanks during production. This proposed AD would require applying cap seals to certain fastener collars inside the fuel tanks. 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/2024/04/12/2024-07562.html","cfr_references":[{"chapter":null,"citation_url":null,"part":39,"title":14}],"citation":"89 FR 25823","comment_url":null,"comments_close_on":"2024-05-28","correction_of":null,"corrections":[],"dates":"The FAA must receive comments on this proposed AD by May 28, 2024.","disposition_notes":null,"docket_ids":["Docket No. FAA-2024-1000","Project Identifier AD-2023-01051-T"],"dockets":[{"supporting_documents":[{"title":"U.S. DOT/FAA - Supplemental AD Documents","document_id":"FAA-2024-1000-0003"}],"agency_name":"FAA","documents":[{"comment_count":8,"comment_start_date":"2024-04-12","updated_at":"2025-01-21T16:58:05.626-05:00","comment_url":"https://www.regulations.gov/commenton/FAA-2024-1000-0001","allow_late_comments":false,"id":"FAA-2024-1000-0001","comment_end_date":"2024-05-29","regulations_dot_gov_open_for_comment":false}],"supporting_documents_count":1,"id":"FAA-2024-1000","title":"AD-2023-01051-T; The Boeing Company Model 747-400F series airplanes; cap seals on fasteners in the fuel tanks"}],"document_number":"2024-07562","effective_on":null,"end_page":25825,"executive_order_notes":null,"executive_order_number":null,"explanation":null,"full_text_xml_url":"https://www.federalregister.gov/documents/full_text/xml/2024/04/12/2024-07562.xml","html_url":"https://www.federalregister.gov/documents/2024/04/12/2024-07562/airworthiness-directives-the-boeing-company-airplanes","images":{},"images_metadata":{},"json_url":"https://www.federalregister.gov/api/v1/documents/2024-07562?publication_date=2024-04-12","mods_url":"https://www.govinfo.gov/metadata/granule/FR-2024-04-12/2024-07562/mods.xml","not_received_for_publication":null,"page_length":3,"page_views":{"count":217,"last_updated":"2026-04-04 16:15:04 -0400"},"pdf_url":"https://www.govinfo.gov/content/pkg/FR-2024-04-12/pdf/2024-07562.pdf","presidential_document_number":null,"proclamation_number":null,"public_inspection_pdf_url":"https://public-inspection.federalregister.gov/2024-07562.pdf?1712839514","publication_date":"2024-04-12","raw_text_url":"https://www.federalregister.gov/documents/full_text/text/2024/04/12/2024-07562.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-2024-1000-0003"}],"regulatory_plan":{"html_url":"https://www.federalregister.gov/regulations/2120-AA64/airworthiness-directives","title":"Airworthiness Directives"},"comments_count":8,"agency_id":"FAA","comments_url":"https://www.regulations.gov/docketBrowser?rpp=50&so=DESC&sb=postedDate&po=0&dct=PS&D=FAA-2024-1000","supporting_documents_count":1,"docket_id":"FAA-2024-1000","document_id":"FAA-2024-1000-0001","regulation_id_number":"2120-AA64","title":"AD-2023-01051-T; The Boeing Company Model 747-400F series airplanes; cap seals on fasteners in the fuel tanks","checked_regulationsdotgov_at":"2025-01-22T21:00:04Z"},"regulations_dot_gov_url":null,"significant":false,"signing_date":null,"start_page":25823,"subtype":null,"title":"Airworthiness Directives; The Boeing Company Airplanes","toc_doc":"The Boeing Company Airplanes","toc_subject":"Airworthiness Directives:\n","topics":["Air transportation","Aircraft","Aviation safety","Incorporation by reference","Safety"],"type":"Proposed Rule","volume":89}
