{"abstract":"We are adopting a new airworthiness directive (AD) for certain Cessna Aircraft Company Model 560XL airplanes. This AD was prompted by reports of jammed or stiff rudder control due to water freezing on the rudder bias cables and pulleys of the stinger. This AD requires modification of the drain installation of the tailcone stinger on the aft canted bulkhead, inspections for drain holes in the forward and aft frames, and modification of the drain holes. We are issuing this AD to prevent ice accumulation on the cables and pulleys of the stinger, which could result in jamming of the rudder and consequent reduced controllability 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/2012/03/21/2012-6522.html","cfr_references":[{"chapter":null,"citation_url":null,"part":39,"title":14}],"citation":"77 FR 16432","comment_url":null,"comments_close_on":null,"correction_of":null,"corrections":[],"dates":"This AD is effective April 25, 2012.","disposition_notes":null,"docket_ids":["Docket No. FAA-2011-1414","Directorate Identifier 2011-NM-227-AD","Amendment 39-16982","AD 2012-06-01"],"dockets":[],"document_number":"2012-6522","effective_on":"2012-04-25","end_page":16434,"executive_order_notes":null,"executive_order_number":null,"full_text_xml_url":"https://www.federalregister.gov/documents/full_text/xml/2012/03/21/2012-6522.xml","html_url":"https://www.federalregister.gov/documents/2012/03/21/2012-6522/airworthiness-directives-cessna-aircraft-company-airplanes","images":{},"images_metadata":{},"json_url":"https://www.federalregister.gov/api/v1/documents/2012-6522?publication_date=2012-03-21","mods_url":"https://www.govinfo.gov/metadata/granule/FR-2012-03-21/2012-6522/mods.xml","not_received_for_publication":null,"page_length":3,"page_views":{"count":294,"last_updated":"2026-08-25 06:15:03 -0400"},"pdf_url":"https://www.govinfo.gov/content/pkg/FR-2012-03-21/pdf/2012-6522.pdf","presidential_document_number":null,"proclamation_number":null,"public_inspection_pdf_url":"https://public-inspection.federalregister.gov/2012-06522.pdf?1332247713","publication_date":"2012-03-21","raw_text_url":"https://www.federalregister.gov/documents/full_text/text/2012/03/21/2012-6522.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":{"supporting_documents":[{"title":"U.S. DOT/FAA - See Attachments","document_id":"FAA-2011-1414-0005"},{"title":"U.S. DOT/FAA  - See Attachments","document_id":"FAA-2011-1414-0002"}],"regulatory_plan":{"html_url":"https://www.federalregister.gov/regulations/2120-AA64/airworthiness-directives","title":"Airworthiness Directives"},"comments_url":"https://www.regulations.gov/docketBrowser?rpp=50&so=DESC&sb=postedDate&po=0&dct=PS&D=FAA-2011-1414","supporting_documents_count":2,"docket_id":"FAA-2011-1414","regulation_id_number":"2120-AA64","title":"2011-NM-227-AD\r\nCessna Aircraft Company Model 560XL airplanes","checked_regulationsdotgov_at":"2012-07-13T05:00:14Z"},"regulations_dot_gov_url":null,"significant":false,"signing_date":null,"start_page":16432,"subtype":null,"title":"Airworthiness Directives; Cessna Aircraft Company Airplanes","toc_doc":"Cessna Aircraft Co.
