{"abstract":"The FAA is adopting a new airworthiness directive (AD) for all McDonnell Douglas Model MD-11 and MD-11F airplanes and certain Model DC-10-10, DC-10-10F, DC-10-15, DC-10-30, DC-10-30F (KC-10A and KDC-10), DC-10-40, DC-10-40F, MD-10-10F, and MD-10-30F airplanes. This AD requires rerouting system 3 hydraulic piping, installing new pipe assemblies and unions, and installing redesigned support brackets for the system 3 hydraulic piping. This AD results from a report of damage to the hydraulic system that occurred when pieces of a ruptured tire from the left main landing gear penetrated the wing trailing edge access panel during takeoff. We are issuing this AD to prevent damage to the system 3 hydraulic piping, which could result in loss of the hydraulic system.","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/2007/09/21/E7-18459.html","cfr_references":[{"chapter":null,"citation_url":null,"part":39,"title":14}],"citation":"72 FR 53927","comment_url":null,"comments_close_on":null,"correction_of":null,"corrections":[],"dates":"This AD becomes effective October 26, 2007.","disposition_notes":null,"docket_ids":["Docket No. FAA-2007-28301","Directorate Identifier 2007-NM-061-AD","Amendment 39-15208","AD 2007-19-17"],"dockets":[],"document_number":"E7-18459","effective_on":"2007-10-26","end_page":53928,"executive_order_notes":null,"executive_order_number":null,"explanation":null,"full_text_xml_url":"https://www.federalregister.gov/documents/full_text/xml/2007/09/21/E7-18459.xml","html_url":"https://www.federalregister.gov/documents/2007/09/21/E7-18459/airworthiness-directives-mcdonnell-douglas-model-md-11-md-11f-dc-10-10-dc-10-10f-dc-10-15-dc-10-30","images":{},"images_metadata":{},"json_url":"https://www.federalregister.gov/api/v1/documents/E7-18459?publication_date=2007-09-21","mods_url":"https://www.govinfo.gov/metadata/granule/FR-2007-09-21/E7-18459/mods.xml","not_received_for_publication":null,"page_length":2,"page_views":{"count":83,"last_updated":"2026-04-04 14:15:05 -0400"},"pdf_url":"https://www.govinfo.gov/content/pkg/FR-2007-09-21/pdf/E7-18459.pdf","presidential_document_number":null,"proclamation_number":null,"public_inspection_pdf_url":null,"publication_date":"2007-09-21","raw_text_url":"https://www.federalregister.gov/documents/full_text/text/2007/09/21/E7-18459.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":{"checked_regulationsdotgov_at":"2011-11-13T02:17:50Z"},"regulations_dot_gov_url":null,"significant":false,"signing_date":null,"start_page":53927,"subtype":null,"title":"Airworthiness Directives; McDonnell Douglas Model MD-11, MD-11F, DC-10-10, DC-10-10F, DC-10-15, DC-10-30, DC-10-30F (KC-10A and KDC-10), DC-10-40, DC-10-40F, MD-10-10F, and MD-10-30F Airplanes","toc_doc":"McDonnell Douglas","toc_subject":"Airworthiness directives:","topics":["Air transportation","Aircraft","Aviation safety","Incorporation by reference","Safety"],"type":"Rule","volume":72}
