{"abstract":"The FAA adopts a new airworthiness directive (AD) for certain Cessna Aircraft Company (Cessna) 172, 182, and 206 series airplanes. This AD requires you to remove the crew seats, modify the seat base/ back attach brackets, and reinstall the seats of the affected airplanes. This AD results from reports of the seat base/back attach bracket failing where it is welded to the seat base. We are issuing 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":"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/2008/03/04/E8-3771.html","cfr_references":[{"chapter":null,"citation_url":null,"part":39,"title":14}],"citation":"73 FR 11536","comment_url":null,"comments_close_on":null,"correction_of":null,"corrections":[],"dates":"This AD becomes effective on April 8, 2008.","disposition_notes":null,"docket_ids":["Docket No. FAA-2007-28433","Directorate Identifier 2007-CE-052-AD","Amendment 39-15403","AD 2008-05-09"],"dockets":[],"document_number":"E8-3771","effective_on":"2008-04-08","end_page":11538,"executive_order_notes":null,"executive_order_number":null,"full_text_xml_url":"https://www.federalregister.gov/documents/full_text/xml/2008/03/04/E8-3771.xml","html_url":"https://www.federalregister.gov/documents/2008/03/04/E8-3771/airworthiness-directives-cessna-aircraft-company-172-182-and-206-series-airplanes","images":{},"images_metadata":{},"json_url":"https://www.federalregister.gov/api/v1/documents/E8-3771?publication_date=2008-03-04","mods_url":"https://www.govinfo.gov/metadata/granule/FR-2008-03-04/E8-3771/mods.xml","not_received_for_publication":null,"page_length":3,"page_views":{"count":1087,"last_updated":"2026-10-24 06:15:04 -0400"},"pdf_url":"https://www.govinfo.gov/content/pkg/FR-2008-03-04/pdf/E8-3771.pdf","presidential_document_number":null,"proclamation_number":null,"public_inspection_pdf_url":null,"publication_date":"2008-03-04","raw_text_url":"https://www.federalregister.gov/documents/full_text/text/2008/03/04/E8-3771.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":{"checked_regulationsdotgov_at":"2011-11-13T21:31:09Z"},"regulations_dot_gov_url":null,"significant":false,"signing_date":null,"start_page":11536,"subtype":null,"title":"Airworthiness Directives; Cessna Aircraft Company 172, 182, and 206 Series Airplanes","toc_doc":"Cessna Aircraft Company 172 et al.","toc_subject":"Airworthiness Directives:","topics":["Air transportation","Aircraft","Aviation safety","Incorporation by reference","Safety"],"type":"Rule","volume":73}
