{"abstract":"We propose to adopt a new airworthiness directive (AD) for certain Cessna Aircraft Company (Cessna), Models 172, 182, and 206 series airplanes. This proposed AD would require you to remove the seats, modify the seat base/back attach brackets, and reinstall the seats of all the crew seats of the affected airplanes and seats 3 and 4 on Model 206 series airplanes. This proposed AD results from reports of the seat base/back attach bracket failing where it is welded to the seat base. We are proposing this AD to prevent failure of the seat base/back attach brackets, which could result in the seats collapsing backwards during flight with consequent loss of control.","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/2007/07/19/E7-13984.html","cfr_references":[{"chapter":null,"citation_url":null,"part":39,"title":14}],"citation":"72 FR 39584","comment_url":null,"comments_close_on":"2007-09-17","correction_of":null,"corrections":[],"dates":"We must receive comments on this proposed AD by September 17, 2007.","disposition_notes":null,"docket_ids":["Docket No. FAA-2007-28433","Directorate Identifier 2007-CE-052-AD"],"dockets":[],"document_number":"E7-13984","effective_on":null,"end_page":39586,"executive_order_notes":null,"executive_order_number":null,"full_text_xml_url":"https://www.federalregister.gov/documents/full_text/xml/2007/07/19/E7-13984.xml","html_url":"https://www.federalregister.gov/documents/2007/07/19/E7-13984/airworthiness-directives-cessna-aircraft-company-models-172-182-and-206-series-airplanes","images":{},"images_metadata":{},"json_url":"https://www.federalregister.gov/api/v1/documents/E7-13984?publication_date=2007-07-19","mods_url":"https://www.govinfo.gov/metadata/granule/FR-2007-07-19/E7-13984/mods.xml","not_received_for_publication":null,"page_length":3,"page_views":{"count":101,"last_updated":"2026-10-25 08:15:04 -0400"},"pdf_url":"https://www.govinfo.gov/content/pkg/FR-2007-07-19/pdf/E7-13984.pdf","presidential_document_number":null,"proclamation_number":null,"public_inspection_pdf_url":null,"publication_date":"2007-07-19","raw_text_url":"https://www.federalregister.gov/documents/full_text/text/2007/07/19/E7-13984.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":"2011-11-12T22:15:13Z"},"regulations_dot_gov_url":null,"significant":false,"signing_date":null,"start_page":39584,"subtype":null,"title":"Airworthiness Directives; Cessna Aircraft Company, Models 172, 182, and 206 Series Airplanes","toc_doc":"Cessna","toc_subject":"Airworthiness directives:","topics":["Air transportation","Aircraft","Aviation safety","Safety"],"type":"Proposed Rule","volume":72}
