These aeroplanes are equipped with a Honeywell KAP 140 autopilot computer system installed in the centre instrument control panel near the throttle.\n\nThe original issue of this Directive required the installation of an update to the operating software of the KAP 140 autopilot computer system, a change to the unit's part number and change of the software modification identification tag. These actions prevent unintentional engagement of the KAP 140 autopilot computer system, which could cause the pilot to take inappropriate actions.\n\nAmendment 1 corrected an anomaly in the T206H serial number range and continued the requirements of the original issue of the Directive.\n\nThis Amendment is issued to correct a grammatical error and has no other effect.\n\nThe original issue of this Airworthiness Directive became effective on 19 February 2004.\n\nAmendment 1 became effective 18 March 2004.\n\n![](image.002.png)  \n\nJames Coyne\n\nDelegate of the Civil Aviation Safety Authority 27 April 2004\n\n![](image.001.png)  \n\nThe above AD is notified in the Commonwealth of Australia Gazette on 19 May 2004.","sortOrder":1}],"analysis":{"flash_summary_failed":{"failed":true,"reason":"Unauthenticated.
