{"abstract":"We are adopting a new airworthiness directive (AD) for all Cessna Aircraft Company (Cessna) Model 402C airplanes modified by Supplemental Type Certificate (STC) SA927NW and Model 414A airplanes modified by STC SA892NW. This AD was prompted by report of a Cessna Model 414A airplane modified by STC SA892NW that experienced an asymmetrical flap condition causing an uncommanded roll when the pilot set the flaps to the approach position. We are issuing this AD to prevent failure of the flap system, which could result in an asymmetrical flap condition. This condition could result in loss of control.","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/2012/11/21/2012-27456.html","cfr_references":[{"chapter":null,"citation_url":null,"part":39,"title":14}],"citation":"77 FR 69742","comment_url":null,"comments_close_on":null,"correction_of":null,"corrections":[],"dates":"This AD is effective December 26, 2012.","disposition_notes":null,"docket_ids":["Docket No. FAA-2010-1084","Directorate Identifier 2010-CE-056-AD","Amendment 39-17257","AD 2012-23-01"],"dockets":[],"document_number":"2012-27456","effective_on":"2012-12-26","end_page":69744,"executive_order_notes":null,"executive_order_number":null,"full_text_xml_url":"https://www.federalregister.gov/documents/full_text/xml/2012/11/21/2012-27456.xml","html_url":"https://www.federalregister.gov/documents/2012/11/21/2012-27456/airworthiness-directives-cessna-aircraft-company-airplanes","images":{},"images_metadata":{},"json_url":"https://www.federalregister.gov/api/v1/documents/2012-27456?publication_date=2012-11-21","mods_url":"https://www.govinfo.gov/metadata/granule/FR-2012-11-21/2012-27456/mods.xml","not_received_for_publication":null,"page_length":3,"page_views":{"count":216,"last_updated":"2026-10-25 04:15:05 -0400"},"pdf_url":"https://www.govinfo.gov/content/pkg/FR-2012-11-21/pdf/2012-27456.pdf","presidential_document_number":null,"proclamation_number":null,"public_inspection_pdf_url":"https://public-inspection.federalregister.gov/2012-27456.pdf?1353422244","publication_date":"2012-11-21","raw_text_url":"https://www.federalregister.gov/documents/full_text/text/2012/11/21/2012-27456.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-2010-1084-0004"},{"title":"U.S. DOT/FAA -  See Attachments","document_id":"FAA-2010-1084-0002"}],"comments_url":"https://www.regulations.gov/docketBrowser?rpp=50&so=DESC&sb=postedDate&po=0&dct=PS&D=FAA-2010-1084","supporting_documents_count":2,"docket_id":"FAA-2010-1084","regulation_id_number":null,"title":"2010-CE-056-AD","checked_regulationsdotgov_at":"2012-12-11T08:07:06Z"},"regulations_dot_gov_url":null,"significant":false,"signing_date":null,"start_page":69742,"subtype":null,"title":"Airworthiness Directives; Cessna Aircraft Company Airplanes","toc_doc":"Cessna Aircraft Company Airplanes","toc_subject":"Airworthiness Directives:","topics":["Air transportation","Aircraft","Aviation safety","Incorporation by reference","Safety"],"type":"Rule","volume":77}
