{"abstract":"We are adopting a new airworthiness directive (AD) for certain The Boeing Company Model 757 airplanes. This AD was prompted by fuel system reviews conducted by the manufacturer. This AD requires modifying the fuel quantity indication system (FQIS) wiring to prevent development of an ignition source inside the center fuel tank. We are issuing this AD to prevent ignition sources inside the center fuel tank, which, in combination with flammable fuel vapors, could result in a fuel tank explosion and consequent loss of the airplane.","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/2016/04/05/2016-07150.html","cfr_references":[{"chapter":null,"citation_url":null,"part":39,"title":14}],"citation":"81 FR 19472","comment_url":null,"comments_close_on":null,"correction_of":null,"corrections":[],"dates":"This AD is effective May 10, 2016.","disposition_notes":null,"docket_ids":["Docket No. FAA-2012-0187","Directorate Identifier 2011-NM-094-AD","Amendment 39-18452","AD 2016-07-07"],"dockets":[{"supporting_documents":[{"title":"U.S. DOT/FAA - Various Supplemental AD Documents","document_id":"FAA-2012-0187-0022"},{"title":"U.S. DOT/FAA- See Attachment","document_id":"FAA-2012-0187-0016"},{"title":"U.S. DOT/FAA - See Attachments","document_id":"FAA-2012-0187-0002"}],"agency_name":null,"documents":[{"comment_count":0,"comment_start_date":"2016-04-05","updated_at":"2023-03-01T13:22:01.352-05:00","comment_url":"https://www.regulations.gov/commenton/FAA-2012-0187-0030","allow_late_comments":null,"id":"FAA-2012-0187-0030","comment_end_date":null,"regulations_dot_gov_open_for_comment":false}],"supporting_documents_count":3,"id":"FAA-2012-0187","title":"2011?NM?094?AD The Boeing Company Model 757 airplanes"}],"document_number":"2016-07150","effective_on":"2016-05-10","end_page":19482,"executive_order_notes":null,"executive_order_number":null,"explanation":null,"full_text_xml_url":"https://www.federalregister.gov/documents/full_text/xml/2016/04/05/2016-07150.xml","html_url":"https://www.federalregister.gov/documents/2016/04/05/2016-07150/airworthiness-directives-the-boeing-company-airplanes","images":{},"images_metadata":{},"json_url":"https://www.federalregister.gov/api/v1/documents/2016-07150?publication_date=2016-04-05","mods_url":"https://www.govinfo.gov/metadata/granule/FR-2016-04-05/2016-07150/mods.xml","not_received_for_publication":null,"page_length":11,"page_views":{"count":850,"last_updated":"2026-04-04 12:15:04 -0400"},"pdf_url":"https://www.govinfo.gov/content/pkg/FR-2016-04-05/pdf/2016-07150.pdf","presidential_document_number":null,"proclamation_number":null,"public_inspection_pdf_url":"https://public-inspection.federalregister.gov/2016-07150.pdf?1459773921","publication_date":"2016-04-05","raw_text_url":"https://www.federalregister.gov/documents/full_text/text/2016/04/05/2016-07150.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-2012-0187-0022"},{"title":"U.S. DOT/FAA- See Attachment","document_id":"FAA-2012-0187-0016"},{"title":"U.S. DOT/FAA - See Attachments","document_id":"FAA-2012-0187-0002"}],"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-2012-0187","supporting_documents_count":3,"docket_id":"FAA-2012-0187","document_id":"FAA-2012-0187-0030","regulation_id_number":"2120-AA64","title":"2011?NM?094?AD The Boeing Company Model 757 airplanes","checked_regulationsdotgov_at":"2023-03-01T18:22:00Z"},"regulations_dot_gov_url":null,"significant":false,"signing_date":null,"start_page":19472,"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":81}
