{"abstract":"The FAA proposes to adopt a new airworthiness directive (AD) for certain Raytheon Aircraft Company (Raytheon) Model B300 airplanes. This proposed AD would require you to modify the cabin passenger seats by installing a modification kit on each passenger seat, removing the existing technical standard order (TSO) label, and re-identifying each modified passenger seat assembly with a new part number. This proposed AD results from the seats not meeting the ultimate load requirements of 14 CFR part 23 during structural testing of the seat with design changes. We are issuing this proposed AD to prevent the passenger seats from failing during emergency landing conditions when high inertial loadings occur. Passenger seat failure may result in occupant injury.","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/2006/05/19/E6-7636.html","cfr_references":[{"chapter":null,"citation_url":null,"part":39,"title":14}],"citation":"71 FR 29090","comment_url":null,"comments_close_on":"2006-07-14","correction_of":null,"corrections":[],"dates":"We must receive comments on this proposed AD by July 14, 2006.","disposition_notes":null,"docket_ids":["Docket No. FAA-2005-22103","Directorate Identifier 2005-CE-42-AD"],"dockets":[],"document_number":"E6-7636","effective_on":null,"end_page":29092,"executive_order_notes":null,"executive_order_number":null,"explanation":null,"full_text_xml_url":"https://www.federalregister.gov/documents/full_text/xml/2006/05/19/E6-7636.xml","html_url":"https://www.federalregister.gov/documents/2006/05/19/E6-7636/airworthiness-directives-raytheon-aircraft-company-model-b300-airplanes","images":{},"images_metadata":{},"json_url":"https://www.federalregister.gov/api/v1/documents/E6-7636?publication_date=2006-05-19","mods_url":"https://www.govinfo.gov/metadata/granule/FR-2006-05-19/E6-7636/mods.xml","not_received_for_publication":null,"page_length":3,"page_views":{"count":57,"last_updated":"2026-04-10 04:15:05 -0400"},"pdf_url":"https://www.govinfo.gov/content/pkg/FR-2006-05-19/pdf/E6-7636.pdf","presidential_document_number":null,"proclamation_number":null,"public_inspection_pdf_url":null,"publication_date":"2006-05-19","raw_text_url":"https://www.federalregister.gov/documents/full_text/text/2006/05/19/E6-7636.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":"2011-11-12T19:23:59Z"},"regulations_dot_gov_url":null,"significant":false,"signing_date":null,"start_page":29090,"subtype":null,"title":"Airworthiness Directives; Raytheon Aircraft Company Model B300 Airplanes","toc_doc":"Raytheon","toc_subject":"Airworthiness directives:","topics":["Air transportation","Aircraft","Aviation safety","Safety"],"type":"Proposed Rule","volume":71}
