{"abstract":"We propose to adopt a new airworthiness directive (AD) for certain Bell Helicopter Textron Canada Inc. (BHT) Model 206A, 206B, and 206L helicopters. This proposed AD would require replacing certain part-numbered engine auto-relight kit control boxes. This proposed AD is prompted by a design review that revealed the control box chipset did not meet the required temperature range requirements, which could cause the control box to malfunction, disabling the engine auto-relight system. This condition could result in increased pilot workload during a power loss emergency and subsequent loss of control of the aircraft.","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/2013/04/22/2013-09415.html","cfr_references":[{"chapter":null,"citation_url":null,"part":39,"title":14}],"citation":"78 FR 23688","comment_url":null,"comments_close_on":"2013-06-21","correction_of":null,"corrections":[],"dates":"We must receive comments on this proposed AD by June 21, 2013.","disposition_notes":null,"docket_ids":["Docket No. FAA-2013-0349","Directorate Identifier 2012-SW-058-AD"],"dockets":[],"document_number":"2013-09415","effective_on":null,"end_page":23690,"executive_order_notes":null,"executive_order_number":null,"full_text_xml_url":"https://www.federalregister.gov/documents/full_text/xml/2013/04/22/2013-09415.xml","html_url":"https://www.federalregister.gov/documents/2013/04/22/2013-09415/airworthiness-directives-bell-helicopter-textron-canada-inc-helicopters","images":{},"images_metadata":{},"json_url":"https://www.federalregister.gov/api/v1/documents/2013-09415?publication_date=2013-04-22","mods_url":"https://www.govinfo.gov/metadata/granule/FR-2013-04-22/2013-09415/mods.xml","not_received_for_publication":null,"page_length":3,"page_views":{"count":174,"last_updated":"2026-08-24 16:15:16 -0400"},"pdf_url":"https://www.govinfo.gov/content/pkg/FR-2013-04-22/pdf/2013-09415.pdf","presidential_document_number":null,"proclamation_number":null,"public_inspection_pdf_url":"https://public-inspection.federalregister.gov/2013-09415.pdf?1366375706","publication_date":"2013-04-22","raw_text_url":"https://www.federalregister.gov/documents/full_text/text/2013/04/22/2013-09415.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 - See Attachments","document_id":"FAA-2013-0349-0005"},{"title":"U.S. DOT/FAA - See Attachment","document_id":"FAA-2013-0349-0003"},{"title":"U.S. DOT/FAA - See Attachments","document_id":"FAA-2013-0349-0002"}],"regulatory_plan":{"html_url":"https://www.federalregister.gov/regulations/2120-AA66/airspace-actions","title":"Airspace Actions"},"comments_url":"https://www.regulations.gov/docketBrowser?rpp=50&so=DESC&sb=postedDate&po=0&dct=PS&D=FAA-2013-0349","supporting_documents_count":3,"docket_id":"FAA-2013-0349","regulation_id_number":"2120-AA66","title":"2012-SW-058-AD Bell Helicopter Textron Canada, Inc., Model 206A, 206B, and 206L helicopters, to require replacing certain part-numbered engine auto-relight kit control boxes.","checked_regulationsdotgov_at":"2013-05-26T05:01:15Z"},"regulations_dot_gov_url":null,"significant":false,"signing_date":null,"start_page":23688,"subtype":null,"title":"Airworthiness Directives; Bell Helicopter Textron Canada Inc.
