{"abstract":"We are adopting a new airworthiness directive (AD) for all General Electric Company (GE) CF6-80C2A1, CF6-80C2A2, CF6-80C2A3, CF6- 80C2A5, CF6-80C2A5F, CF6-80C2A8, CF6-80C2B1, CF6-80C2B1F, CF6-80C2B1F1, CF6-80C2B1F2, CF6-80C2B2, CF6-80C2B2F, CF6-80C2B3F, CF6-80C2B4, CF6- 80C2B4F, CF6-80C2B5F, CF6-80C2B6, CF6-80C2B6F, CF6-80C2B6FA, CF6- 80C2B7F, CF6-80C2B8F, CF6-80C2D1F, CF6-80C2L1F, CF6-80C2K1F and CF6- 80E1A1, CF6-80E1A2, CF6-80E1A3, CF6-80E1A4, and CF6-80E1A4/B turbofan engines. This AD was prompted by reports of a burn-through of the accessory heat shield during an engine fire, propagating the fire into the accessory compartment and igniting additional flammable fuel source. This AD requires replacing the accessory heat shield assembly. We are issuing this AD to prevent fires from propagating into the accessory compartment, resulting in an uncontrolled engine fire, and damage to 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/2016/04/27/2016-09686.html","cfr_references":[{"chapter":null,"citation_url":null,"part":39,"title":14}],"citation":"81 FR 24699","comment_url":null,"comments_close_on":null,"correction_of":null,"corrections":[],"dates":"This AD is effective June 1, 2016.","disposition_notes":null,"docket_ids":["Docket No. FAA-2015-4344","Directorate Identifier 2015-NE-32-AD","Amendment 39-18486","AD 2016-08-10"],"dockets":[{"supporting_documents":[{"title":"U.S. DOT/FAA - Supplemental AD Documents","document_id":"FAA-2015-4344-0019"}],"agency_name":null,"documents":[{"comment_count":0,"comment_start_date":"2016-04-27","updated_at":"2023-03-01T13:22:20.721-05:00","comment_url":"https://www.regulations.gov/commenton/FAA-2015-4344-0018","allow_late_comments":null,"id":"FAA-2015-4344-0018","comment_end_date":null,"regulations_dot_gov_open_for_comment":false}],"supporting_documents_count":1,"id":"FAA-2015-4344","title":"2015-NE-32-AD "}],"document_number":"2016-09686","effective_on":"2016-06-01","end_page":24701,"executive_order_notes":null,"executive_order_number":null,"explanation":null,"full_text_xml_url":"https://www.federalregister.gov/documents/full_text/xml/2016/04/27/2016-09686.xml","html_url":"https://www.federalregister.gov/documents/2016/04/27/2016-09686/airworthiness-directives-general-electric-company-turbofan-engines","images":{},"images_metadata":{},"json_url":"https://www.federalregister.gov/api/v1/documents/2016-09686?publication_date=2016-04-27","mods_url":"https://www.govinfo.gov/metadata/granule/FR-2016-04-27/2016-09686/mods.xml","not_received_for_publication":null,"page_length":3,"page_views":{"count":1300,"last_updated":"2026-04-04 18:15:03 -0400"},"pdf_url":"https://www.govinfo.gov/content/pkg/FR-2016-04-27/pdf/2016-09686.pdf","presidential_document_number":null,"proclamation_number":null,"public_inspection_pdf_url":"https://public-inspection.federalregister.gov/2016-09686.pdf?1461674734","publication_date":"2016-04-27","raw_text_url":"https://www.federalregister.gov/documents/full_text/text/2016/04/27/2016-09686.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 - Supplemental AD Documents","document_id":"FAA-2015-4344-0019"}],"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-2015-4344","supporting_documents_count":1,"docket_id":"FAA-2015-4344","document_id":"FAA-2015-4344-0018","regulation_id_number":"2120-AA64","title":"2015-NE-32-AD ","checked_regulationsdotgov_at":"2023-03-01T18:22:19Z"},"regulations_dot_gov_url":null,"significant":false,"signing_date":null,"start_page":24699,"subtype":null,"title":"Airworthiness Directives; General Electric Company Turbofan Engines","toc_doc":"General Electric Company Turbofan Engines","toc_subject":"Airworthiness Directives:","topics":["Air transportation","Aircraft","Aviation safety","Incorporation by reference","Safety"],"type":"Rule","volume":81}
