{"abstract":"This amendment adopts a new airworthiness directive (AD), applicable to certain Boeing Model 767-300 and -400ER series airplanes, that requires replacing the tie rods for the waste tank cradle, related investigative actions, corrective actions, and special retrofit action if necessary. This action is necessary to prevent possible failure of the main deck floor stanchions and consequent collapse of the main floor during an emergency landing, which could result in passenger injury and impede passenger evacuation from the airplane. This action is intended to address the identified unsafe condition.","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/2004/12/09/04-26917.html","cfr_references":[{"chapter":null,"citation_url":null,"part":39,"title":14}],"citation":"69 FR 71340","comment_url":null,"comments_close_on":null,"correction_of":null,"corrections":[],"dates":"Effective January 13, 2005.","disposition_notes":null,"docket_ids":["Docket No. 2004-NM-33-AD","Amendment 39-13898","AD 2004-25-10"],"dockets":[],"document_number":"04-26917","effective_on":"2005-01-13","end_page":71342,"executive_order_notes":null,"executive_order_number":null,"explanation":null,"full_text_xml_url":"https://www.federalregister.gov/documents/full_text/xml/2004/12/09/04-26917.xml","html_url":"https://www.federalregister.gov/documents/2004/12/09/04-26917/airworthiness-directives-boeing-model-767-300-and--400er-series-airplanes","images":{},"images_metadata":{},"json_url":"https://www.federalregister.gov/api/v1/documents/04-26917?publication_date=2004-12-09","mods_url":"https://www.govinfo.gov/metadata/granule/FR-2004-12-09/04-26917/mods.xml","not_received_for_publication":null,"page_length":3,"page_views":{"count":11,"last_updated":"2026-04-05 00:15:04 -0400"},"pdf_url":"https://www.govinfo.gov/content/pkg/FR-2004-12-09/pdf/04-26917.pdf","presidential_document_number":null,"proclamation_number":null,"public_inspection_pdf_url":null,"publication_date":"2004-12-09","raw_text_url":"https://www.federalregister.gov/documents/full_text/text/2004/12/09/04-26917.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":{"checked_regulationsdotgov_at":"2011-11-12T14:13:36Z"},"regulations_dot_gov_url":null,"significant":false,"signing_date":null,"start_page":71340,"subtype":null,"title":"Airworthiness Directives; Boeing Model 767-300 and -400ER Series Airplanes","toc_doc":"Boeing","toc_subject":"Airworthiness directives:","topics":["Air transportation","Aircraft","Aviation safety","Incorporation by reference","Safety"],"type":"Rule","volume":69}
