{"abstract":"This amendment adopts a new airworthiness directive (AD) that applies to all Raytheon Aircraft Company (Raytheon) 58, 60, 90, 100, 200, and 300 series and Model 2000 airplanes (formerly referred to as Beech 58, 60, 90, 100, 200, and 300 series and Beech Model 2000 airplanes). This AD requires replacing certain AlliedSignal Aerospace outflow/safety valves in the pressurization system with new or serviceable valves. The AD results from a report of cracking and consequent failure of the affected outflow safety valves in the pressurization system. Investigation has revealed problems during the manufacturing process of certain AlliedSignal outflow/safety valves. The actions specified by this AD are intended to prevent outflow/safety valve cracking and consequent failure, which could result in rapid decompression of the airplane.","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/1997/12/03/97-31676.html","cfr_references":[{"chapter":null,"citation_url":null,"part":"39","title":14}],"citation":"62 FR 63831","comment_url":null,"comments_close_on":null,"correction_of":null,"corrections":[],"dates":"January 11, 1998.","disposition_notes":null,"docket_ids":["Docket No. 97-CE-33-AD","Amendment 39-10224","AD 97-25-01"],"dockets":[],"document_number":"97-31676","effective_on":"1998-01-11","end_page":63834,"executive_order_notes":null,"executive_order_number":null,"full_text_xml_url":null,"html_url":"https://www.federalregister.gov/documents/1997/12/03/97-31676/airworthiness-directives-raytheon-aircraft-company-58-60-90-100-200-and-300-series-and-model-2000","images":{},"images_metadata":{},"json_url":"https://www.federalregister.gov/api/v1/documents/97-31676?publication_date=1997-12-03","mods_url":"https://www.govinfo.gov/metadata/granule/FR-1997-12-03/97-31676/mods.xml","not_received_for_publication":null,"page_length":4,"page_views":{"count":29,"last_updated":"2026-08-25 10:15:04 -0400"},"pdf_url":"https://www.govinfo.gov/content/pkg/FR-1997-12-03/pdf/97-31676.pdf","presidential_document_number":null,"proclamation_number":null,"public_inspection_pdf_url":null,"publication_date":"1997-12-03","raw_text_url":"https://www.federalregister.gov/documents/full_text/text/1997/12/03/97-31676.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":{},"regulations_dot_gov_url":null,"significant":false,"signing_date":null,"start_page":63831,"subtype":null,"title":"Airworthiness Directives; Raytheon Aircraft Company 58, 60, 90, 100, 200, and 300 Series and Model 2000 Airplanes","toc_doc":null,"toc_subject":null,"topics":[],"type":"Rule","volume":62}
