{"abstract":"This document proposes to adopt a new airworthiness directive (AD) that would apply to certain Cessna Aircraft Company (Cessna) Models 172R, 172S, 182S, 182T, T182T, 206H, and T206H airplanes that are equipped with a Honeywell KAP 140 autopilot computer system installed on the center instrument control panel near the throttle. This proposed AD would require you to install an update to the operating software of the KAP 140 autopilot computer system, change the unit's part number, and change the software modification identification tab. This proposed AD is the result of reports of inadvertent and undetected engagement of the autopilot system. The actions specified by this proposed AD are intended to prevent unintentionally engaging the KAP 140 autopilot computer system, which could cause the pilot to take inappropriate actions.","action":"Notice of proposed rulemaking (NPRM).","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/2003/07/29/03-19197.html","cfr_references":[{"chapter":null,"citation_url":null,"part":39,"title":14}],"citation":"68 FR 44497","comment_url":null,"comments_close_on":"2003-09-22","correction_of":null,"corrections":[],"dates":"The Federal Aviation Administration (FAA) must receive any comments on this proposed rule on or before September 22, 2003.","disposition_notes":null,"docket_ids":["Docket No. 2003-CE-28-AD"],"dockets":[],"document_number":"03-19197","effective_on":null,"end_page":44499,"executive_order_notes":null,"executive_order_number":null,"full_text_xml_url":"https://www.federalregister.gov/documents/full_text/xml/2003/07/29/03-19197.xml","html_url":"https://www.federalregister.gov/documents/2003/07/29/03-19197/airworthiness-directives-cessna-aircraft-company-models-172r-172s-182s-182t-t182t-206h-and-t206h","images":{},"images_metadata":{},"json_url":"https://www.federalregister.gov/api/v1/documents/03-19197?publication_date=2003-07-29","mods_url":"https://www.govinfo.gov/metadata/granule/FR-2003-07-29/03-19197/mods.xml","not_received_for_publication":null,"page_length":3,"page_views":{"count":24,"last_updated":"2026-10-24 02:15:05 -0400"},"pdf_url":"https://www.govinfo.gov/content/pkg/FR-2003-07-29/pdf/03-19197.pdf","presidential_document_number":null,"proclamation_number":null,"public_inspection_pdf_url":null,"publication_date":"2003-07-29","raw_text_url":"https://www.federalregister.gov/documents/full_text/text/2003/07/29/03-19197.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":44497,"subtype":null,"title":"Airworthiness Directives; Cessna Aircraft Company Models 172R, 172S, 182S, 182T, T182T, 206H, and T206H Airplanes","toc_doc":"Cessna","toc_subject":"Airworthiness directives:","topics":["Air transportation","Aircraft","Aviation safety","Safety"],"type":"Proposed Rule","volume":68}
