{"abstract":"The FAA is adopting a new airworthiness directive (AD) for certain Boeing Model 757-200 and -300 series airplanes. This AD requires changes to existing wiring; installation of new circuit breakers, relays, relay connectors, and wiring; and replacement of certain circuit breakers with higher-rated circuit breakers. For certain airplanes, this AD also requires modification of wiring of the control module assembly for the electrical systems. This AD results from an in-flight entertainment (IFE) systems review. We are issuing this AD to ensure that the flightcrew is able to turn off electrical power to the IFE system and other non-essential electrical systems through utility bus switches in the flight compartment. The flightcrew's inability to turn off power to the IFE system and other non-essential electrical systems during a non-normal or emergency situation could result in the inability to control smoke or fumes in the airplane flight deck or cabin.","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/2007/08/09/E7-15410.html","cfr_references":[{"chapter":null,"citation_url":null,"part":39,"title":14}],"citation":"72 FR 44740","comment_url":null,"comments_close_on":null,"correction_of":null,"corrections":[],"dates":"This AD becomes effective September 13, 2007.","disposition_notes":null,"docket_ids":["Docket No. FAA-2006-25326","Directorate Identifier 2006-NM-081-AD","Amendment 39-15151","AD 2007-16-12"],"dockets":[],"document_number":"E7-15410","effective_on":"2007-09-13","end_page":44744,"executive_order_notes":null,"executive_order_number":null,"explanation":null,"full_text_xml_url":"https://www.federalregister.gov/documents/full_text/xml/2007/08/09/E7-15410.xml","html_url":"https://www.federalregister.gov/documents/2007/08/09/E7-15410/airworthiness-directives-boeing-model-757-200-and--300-series-airplanes","images":{},"images_metadata":{},"json_url":"https://www.federalregister.gov/api/v1/documents/E7-15410?publication_date=2007-08-09","mods_url":"https://www.govinfo.gov/metadata/granule/FR-2007-08-09/E7-15410/mods.xml","not_received_for_publication":null,"page_length":5,"page_views":{"count":384,"last_updated":"2026-04-04 16:15:04 -0400"},"pdf_url":"https://www.govinfo.gov/content/pkg/FR-2007-08-09/pdf/E7-15410.pdf","presidential_document_number":null,"proclamation_number":null,"public_inspection_pdf_url":null,"publication_date":"2007-08-09","raw_text_url":"https://www.federalregister.gov/documents/full_text/text/2007/08/09/E7-15410.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":"2011-11-12T22:19:55Z"},"regulations_dot_gov_url":null,"significant":false,"signing_date":null,"start_page":44740,"subtype":null,"title":"Airworthiness Directives; Boeing Model 757-200 and -300 Series Airplanes","toc_doc":"Boeing","toc_subject":"Airworthiness directives:","topics":["Air transportation","Aircraft","Aviation safety","Incorporation by reference","Safety"],"type":"Rule","volume":72}
