{"abstract":"We are superseding an existing airworthiness directive (AD) for the products listed above. That AD currently requires fabricating and installing a placard incorporating information that limits operation when there is known or forecast icing and requires replacing a section of the pneumatic supply tube for the tail deice system with a new tube of a different material. This AD requires fabricating and installing a placard incorporating information that limits operation when there is known or forecast icing and requires replacing the entire length of the pneumatic supply tube for the tail deice system with a new tube of a different material. This AD was prompted by reports of two failures of the pneumatic supply tube for the tail deice system outside the area covered by AD 2008-07-10. We are issuing this AD to prevent collapsed pneumatic supply tubes, which could result in failure of the tail deice boots to operate. This failure could lead to loss of control in icing conditions.","action":"Final rule; request for comments.","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/2010/12/16/2010-31438.html","cfr_references":[{"chapter":null,"citation_url":null,"part":39,"title":14}],"citation":"75 FR 78596","comment_url":null,"comments_close_on":null,"correction_of":null,"corrections":[],"dates":"This AD is effective December 20, 2010.","disposition_notes":null,"docket_ids":["Docket No. FAA-2010-1242","Directorate Identifier 2010-CE-062-AD","Amendment 39-16542","AD 2010-26-03"],"dockets":[],"document_number":"2010-31438","effective_on":"2010-12-20","end_page":78599,"executive_order_notes":null,"executive_order_number":null,"explanation":null,"full_text_xml_url":"https://www.federalregister.gov/documents/full_text/xml/2010/12/16/2010-31438.xml","html_url":"https://www.federalregister.gov/documents/2010/12/16/2010-31438/airworthiness-directives-hawker-beechcraft-corporation-models-b200-b200gt-b300-and-b300c-airplanes","images":{},"images_metadata":{},"json_url":"https://www.federalregister.gov/api/v1/documents/2010-31438?publication_date=2010-12-16","mods_url":"https://www.govinfo.gov/metadata/granule/FR-2010-12-16/2010-31438/mods.xml","not_received_for_publication":null,"page_length":4,"page_views":{"count":393,"last_updated":"2026-04-05 02:15:03 -0400"},"pdf_url":"https://www.govinfo.gov/content/pkg/FR-2010-12-16/pdf/2010-31438.pdf","presidential_document_number":null,"proclamation_number":null,"public_inspection_pdf_url":null,"publication_date":"2010-12-16","raw_text_url":"https://www.federalregister.gov/documents/full_text/text/2010/12/16/2010-31438.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":"2011-01-05T08:04:50Z"},"regulations_dot_gov_url":null,"significant":false,"signing_date":null,"start_page":78596,"subtype":null,"title":"Airworthiness Directives; Hawker Beechcraft Corporation Models B200, B200GT, B300, and B300C Airplanes","toc_doc":"Hawker Beechcraft Corp.
