{"abstract":"We are adopting a new airworthiness directive (AD) for the products listed above. This AD requires installing a full authority digital engine control (FADEC) backup battery, replacing the supplement pilot's operating handbook and FAA approved airplane flight manual, and replacing the FADEC backup battery every 12 calendar months. This AD was prompted by an incident where an airplane experienced an in-flight engine shutdown caused by a momentary loss of electrical power to the FADEC. We are issuing this AD to prevent interruption of electrical power to the FADEC, which could result in an uncommanded engine shutdown. This failure could lead to a loss of engine power.","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/2011/04/21/2011-8564.html","cfr_references":[{"chapter":null,"citation_url":null,"part":39,"title":14}],"citation":"76 FR 22298","comment_url":null,"comments_close_on":null,"correction_of":null,"corrections":[],"dates":"This AD is effective May 26, 2011.","disposition_notes":null,"docket_ids":["Docket No. FAA-2010-1243","Directorate Identifier 2010-CE-058-AD","Amendment 39-16626","AD 2011-06-02"],"dockets":[],"document_number":"2011-8564","effective_on":"2011-05-26","end_page":22301,"executive_order_notes":null,"executive_order_number":null,"full_text_xml_url":"https://www.federalregister.gov/documents/full_text/xml/2011/04/21/2011-8564.xml","html_url":"https://www.federalregister.gov/documents/2011/04/21/2011-8564/airworthiness-directives-cessna-aircraft-company-cessna-model-172-airplanes-modified-by-supplemental","images":{},"images_metadata":{},"json_url":"https://www.federalregister.gov/api/v1/documents/2011-8564?publication_date=2011-04-21","mods_url":"https://www.govinfo.gov/metadata/granule/FR-2011-04-21/2011-8564/mods.xml","not_received_for_publication":null,"page_length":4,"page_views":{"count":695,"last_updated":"2026-08-25 00:15:04 -0400"},"pdf_url":"https://www.govinfo.gov/content/pkg/FR-2011-04-21/pdf/2011-8564.pdf","presidential_document_number":null,"proclamation_number":null,"public_inspection_pdf_url":null,"publication_date":"2011-04-21","raw_text_url":"https://www.federalregister.gov/documents/full_text/text/2011/04/21/2011-8564.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":"2011-05-11T08:09:38Z"},"regulations_dot_gov_url":null,"significant":false,"signing_date":null,"start_page":22298,"subtype":null,"title":"Airworthiness Directives; Cessna Aircraft Company (Cessna) Model 172 Airplanes Modified by Supplemental Type Certificate (STC) SA01303WI","toc_doc":"Cessna Aircraft Co.
