{"abstract":"We propose to adopt a new airworthiness directive (AD) for certain Model MD-11 and MD-11F airplanes. This proposed AD would require a one-time inspection to detect damage of the wire assemblies of the tail tank fuel system, a wiring change, and corrective actions if necessary. This proposed AD results from fuel system reviews conducted by the manufacturer. We are proposing this AD to detect and correct a potential of ignition sources inside fuel tanks, which, in combination with flammable vapors, could result in a fuel tank fire or explosion, and consequent loss of the airplane.","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/2010/03/16/2010-5667.html","cfr_references":[{"chapter":null,"citation_url":null,"part":39,"title":14}],"citation":"75 FR 12464","comment_url":null,"comments_close_on":"2010-04-30","correction_of":null,"corrections":[],"dates":"We must receive comments on this proposed AD by April 30, 2010.","disposition_notes":null,"docket_ids":["Docket No. FAA-2010-0228","Directorate Identifier 2009-NM-252-AD"],"dockets":[],"document_number":"2010-5667","effective_on":null,"end_page":12466,"executive_order_notes":null,"executive_order_number":null,"explanation":null,"full_text_xml_url":"https://www.federalregister.gov/documents/full_text/xml/2010/03/16/2010-5667.xml","html_url":"https://www.federalregister.gov/documents/2010/03/16/2010-5667/airworthiness-directives-mcdonnell-douglas-corporation-model-md-11-and-md-11f-airplanes","images":{},"images_metadata":{},"json_url":"https://www.federalregister.gov/api/v1/documents/2010-5667?publication_date=2010-03-16","mods_url":"https://www.govinfo.gov/metadata/granule/FR-2010-03-16/2010-5667/mods.xml","not_received_for_publication":null,"page_length":3,"page_views":{"count":26,"last_updated":"2026-04-04 12:15:04 -0400"},"pdf_url":"https://www.govinfo.gov/content/pkg/FR-2010-03-16/pdf/2010-5667.pdf","presidential_document_number":null,"proclamation_number":null,"public_inspection_pdf_url":null,"publication_date":"2010-03-16","raw_text_url":"https://www.federalregister.gov/documents/full_text/text/2010/03/16/2010-5667.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":"2010-03-17T16:02:18Z"},"regulations_dot_gov_url":null,"significant":false,"signing_date":null,"start_page":12464,"subtype":null,"title":"Airworthiness Directives; McDonnell Douglas Corporation Model MD-11 and MD-11F Airplanes","toc_doc":"McDonnell Douglas Corporation Model MD11 and MD 11F Airplanes","toc_subject":"Airworthiness Directives:","topics":["Air transportation","Aircraft","Aviation safety","Incorporation by reference","Safety"],"type":"Proposed Rule","volume":75}
