{"abstract":"The FAA withdraws a notice of proposed rulemaking (NPRM) that proposed adopting a new airworthiness directive (AD) for Bell Helicopter Textron (Bell) Model 206B helicopters modified with Aeronautical Accessories, Inc. (AAI) Supplemental Type Certificate (STC) No. SH8435SW or SH8419SW with energy attenuating seat installation wire (energy attenuating wire). The proposed AD would have required replacing certain energy attenuating wire with airworthy energy attenuating wire. Since issuing the proposed AD, we have determined that no unsafe condition exists with respect to the STC installed energy attenuating wire. Accordingly, the proposed AD is withdrawn.","action":"Proposed rule; withdrawal.","agencies":[{"raw_name":"DEPARTMENT OF TRANSPORTATION","name":"Transportation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/2006/10/17/E6-17185.html","cfr_references":[{"chapter":null,"citation_url":null,"part":39,"title":14}],"citation":"71 FR 60926","comment_url":null,"comments_close_on":null,"correction_of":null,"corrections":[],"dates":null,"disposition_notes":null,"docket_ids":["Docket No. FAA-2005-22806","Directorate Identifier 2005-SW-04-AD"],"dockets":[],"document_number":"E6-17185","effective_on":null,"end_page":60927,"executive_order_notes":null,"executive_order_number":null,"full_text_xml_url":"https://www.federalregister.gov/documents/full_text/xml/2006/10/17/E6-17185.xml","html_url":"https://www.federalregister.gov/documents/2006/10/17/E6-17185/airworthiness-directives-bell-helicopter-textron-model-206b-helicopters","images":{},"images_metadata":{},"json_url":"https://www.federalregister.gov/api/v1/documents/E6-17185?publication_date=2006-10-17","mods_url":"https://www.govinfo.gov/metadata/granule/FR-2006-10-17/E6-17185/mods.xml","not_received_for_publication":null,"page_length":2,"page_views":{"count":56,"last_updated":"2026-08-26 08:15:05 -0400"},"pdf_url":"https://www.govinfo.gov/content/pkg/FR-2006-10-17/pdf/E6-17185.pdf","presidential_document_number":null,"proclamation_number":null,"public_inspection_pdf_url":null,"publication_date":"2006-10-17","raw_text_url":"https://www.federalregister.gov/documents/full_text/text/2006/10/17/E6-17185.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":"2011-11-12T20:10:52Z"},"regulations_dot_gov_url":null,"significant":false,"signing_date":null,"start_page":60926,"subtype":null,"title":"Airworthiness Directives; Bell Helicopter Textron Model 206B Helicopters","toc_doc":"Bell Helicopter Textron","toc_subject":"Airworthiness directives:","topics":["Air transportation","Aircraft","Aviation safety","Safety"],"type":"Proposed Rule","volume":71}
