{"abstract":"This amendment adopts a new airworthiness directive (AD) that is applicable to certain Cessna Model 560 airplanes. This action requires disengaging and tie-strapping the pitch trim and autopilot servo (servo 1) circuit breakers. This action also provides an optional inspection and follow-on actions that, if accomplished, terminates the requirement to disengage and tie-strap those circuit breakers. This action is necessary to prevent a single-point failure in the trim system from causing a runaway trim condition that the pilot may be unable to stop by using the autopilot-disconnect switch. This condition could result in loss of control of the airplane. This action is intended to address the identified unsafe condition.","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/2003/11/13/03-28166.html","cfr_references":[{"chapter":null,"citation_url":null,"part":39,"title":14}],"citation":"68 FR 64266","comment_url":null,"comments_close_on":null,"correction_of":null,"corrections":[],"dates":"Effective November 28, 2003.","disposition_notes":null,"docket_ids":["Docket No. 2003-NM-225-AD","Amendment 39-13365","AD 2003-23-02"],"dockets":[],"document_number":"03-28166","effective_on":"2003-11-28","end_page":64268,"executive_order_notes":null,"executive_order_number":null,"full_text_xml_url":"https://www.federalregister.gov/documents/full_text/xml/2003/11/13/03-28166.xml","html_url":"https://www.federalregister.gov/documents/2003/11/13/03-28166/airworthiness-directives-cessna-model-560-airplanes","images":{},"images_metadata":{},"json_url":"https://www.federalregister.gov/api/v1/documents/03-28166?publication_date=2003-11-13","mods_url":"https://www.govinfo.gov/metadata/granule/FR-2003-11-13/03-28166/mods.xml","not_received_for_publication":null,"page_length":3,"page_views":{"count":18,"last_updated":"2026-08-24 16:15:16 -0400"},"pdf_url":"https://www.govinfo.gov/content/pkg/FR-2003-11-13/pdf/03-28166.pdf","presidential_document_number":null,"proclamation_number":null,"public_inspection_pdf_url":null,"publication_date":"2003-11-13","raw_text_url":"https://www.federalregister.gov/documents/full_text/text/2003/11/13/03-28166.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":64266,"subtype":null,"title":"Airworthiness Directives; Cessna Model 560 Airplanes","toc_doc":"Cessna","toc_subject":"Airworthiness directives:","topics":["Air transportation","Aircraft","Aviation safety","Incorporation by reference","Safety"],"type":"Rule","volume":68}
