{"abstract":"We are adopting a new airworthiness directive (AD) for all The Boeing Company Model 767 airplanes. This AD was prompted by reports of latently failed fuel shutoff valves discovered during fuel filter replacement. This AD requires revising the maintenance or inspection program to include new airworthiness limitations. We are issuing this AD to detect and correct latent failures of the fuel shutoff valve to the engine and auxiliary power unit (APU), which could result in the inability to shut off fuel to the engine and APU and, in case of certain fires, an uncontrollable fire that could lead to structural failure.","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/2015/09/16/2015-23119.html","cfr_references":[{"chapter":null,"citation_url":null,"part":39,"title":14}],"citation":"80 FR 55512","comment_url":null,"comments_close_on":null,"correction_of":null,"corrections":[],"dates":"This AD is effective October 21, 2015.","disposition_notes":null,"docket_ids":["Docket No. FAA-2014-0127","Directorate Identifier 2013-NM-237-AD","Amendment 39-18265","AD 2015-19-02"],"dockets":[],"document_number":"2015-23119","effective_on":"2015-10-21","end_page":55521,"executive_order_notes":null,"executive_order_number":null,"explanation":null,"full_text_xml_url":"https://www.federalregister.gov/documents/full_text/xml/2015/09/16/2015-23119.xml","html_url":"https://www.federalregister.gov/documents/2015/09/16/2015-23119/airworthiness-directives-the-boeing-company-airplanes","images":{},"images_metadata":{},"json_url":"https://www.federalregister.gov/api/v1/documents/2015-23119?publication_date=2015-09-16","mods_url":"https://www.govinfo.gov/metadata/granule/FR-2015-09-16/2015-23119/mods.xml","not_received_for_publication":null,"page_length":10,"page_views":{"count":1088,"last_updated":"2026-04-04 16:15:04 -0400"},"pdf_url":"https://www.govinfo.gov/content/pkg/FR-2015-09-16/pdf/2015-23119.pdf","presidential_document_number":null,"proclamation_number":null,"public_inspection_pdf_url":"https://public-inspection.federalregister.gov/2015-23119.pdf?1442321115","publication_date":"2015-09-16","raw_text_url":"https://www.federalregister.gov/documents/full_text/text/2015/09/16/2015-23119.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 - Various Supplemental AD Documents","document_id":"FAA-2014-0127-0006"},{"title":"U.S. DOT/FAA - Airworthiness Directive Grid","document_id":"FAA-2014-0127-0005"}],"regulatory_plan":{"html_url":"https://www.federalregister.gov/regulations/2120-AA64/airworthiness-directives","title":"Airworthiness Directives"},"comments_url":"https://www.regulations.gov/docketBrowser?rpp=50&so=DESC&sb=postedDate&po=0&dct=PS&D=FAA-2014-0127","supporting_documents_count":2,"docket_id":"FAA-2014-0127","regulation_id_number":"2120-AA64","title":"2013-NM-237-AD The Boeing Company Model 767 airplanes","checked_regulationsdotgov_at":"2015-10-06T06:00:10Z"},"regulations_dot_gov_url":null,"significant":false,"signing_date":null,"start_page":55512,"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":80}
