{"abstract":"The FAA is adopting a new airworthiness directive (AD) for all The Boeing Company Model 717-200 airplanes. This AD was prompted by a report of a nose landing gear-up landing caused by the failure of the upper lock link assembly. This AD requires repetitive inspections for cracking of the upper lock link assembly 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/2025/11/28/2025-21478.html","cfr_references":[{"chapter":null,"citation_url":null,"part":"39","title":14}],"citation":"90 FR 54552","comment_url":null,"comments_close_on":null,"correction_of":null,"corrections":[],"dates":"This AD is effective January 2, 2026.","disposition_notes":null,"docket_ids":["Docket No. FAA-2025-0739","Project Identifier AD-2025-00196-T","Amendment 39-23177","AD 2025-21-05"],"dockets":[{"supporting_documents":[{"title":"U.S. DOT/FAA - Supplemental AD Document","document_id":"FAA-2025-0739-0003"}],"agency_name":"FAA","documents":[{"comment_count":0,"comment_start_date":"2025-11-28","updated_at":"2025-11-28T11:05:15.699-05:00","comment_url":"https://www.regulations.gov/commenton/FAA-2025-0739-0007","allow_late_comments":false,"id":"FAA-2025-0739-0007","comment_end_date":null,"regulations_dot_gov_open_for_comment":false}],"supporting_documents_count":1,"id":"FAA-2025-0739","title":"AD-2025-00196-T; The Boeing Company Model 717-200 airplanes; nose landing gear"}],"document_number":"2025-21478","effective_on":"2026-01-02","end_page":54555,"executive_order_notes":null,"executive_order_number":null,"full_text_xml_url":"https://www.federalregister.gov/documents/full_text/xml/2025/11/28/2025-21478.xml","html_url":"https://www.federalregister.gov/documents/2025/11/28/2025-21478/airworthiness-directives-the-boeing-company-airplanes","images":{},"images_metadata":{},"json_url":"https://www.federalregister.gov/api/v1/documents/2025-21478?publication_date=2025-11-28","mods_url":"https://www.govinfo.gov/metadata/granule/FR-2025-11-28/2025-21478/mods.xml","not_received_for_publication":null,"page_length":4,"page_views":{"count":322,"last_updated":"2026-10-22 16:15:06 -0400"},"pdf_url":"https://www.govinfo.gov/content/pkg/FR-2025-11-28/pdf/2025-21478.pdf","presidential_document_number":null,"proclamation_number":null,"public_inspection_pdf_url":"https://public-inspection.federalregister.gov/2025-21478.pdf?1764164731","publication_date":"2025-11-28","raw_text_url":"https://www.federalregister.gov/documents/full_text/text/2025/11/28/2025-21478.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 Document","document_id":"FAA-2025-0739-0003"}],"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-2025-0739","supporting_documents_count":1,"docket_id":"FAA-2025-0739","document_id":"FAA-2025-0739-0007","regulation_id_number":"2120-AA64","title":"AD-2025-00196-T; The Boeing Company Model 717-200 airplanes; nose landing gear","checked_regulationsdotgov_at":"2025-11-29T18:55:04Z"},"regulations_dot_gov_url":null,"significant":false,"signing_date":null,"start_page":54552,"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}
