COMMONWEALTH OF AUSTRALIA (Civil Aviation Safety Regulations 1998), PART 39 - 105 CIVIL AVIATION SAFETY AUTHORITY SCHEDULE OF AIRWORTHINESS DIRECTIVES Cessna 180, 182 and Wren 460 Series Aeroplanes AD/CESSNA 180/84 (continued) Page 2 of 2 This Airworthiness Directive becomes effective on 30 September 2004. Background: The United States Federal Aviation Administration (FAA) has received reports of inadvertent and undetected engagement of the autopilot system in Cessna Models 172R, 172S, 182S, 182T, T182T, 206H, and T206H aeroplanes. These aeroplanes are equipped with a Honeywell KAP 140 autopilot computer system installed in the centre instrument control panel near the throttle. However, when issuing AD 2003-24-13 the FAA inadvertently omitted four part numbers from the applicability that was reflected in AD/CESSNA 180/83. This Directive, whilst not superseding AD/CESSNA 180/83, complements that Directive by listing the omitted KAP 140 autopilot computer system part numbers. This Directive requires the installation of an update to the operating software of the KAP 140 autopilot computer system. This action is intended to prevent unintentional engagement of the KAP 140 autopilot computer system, which could cause the pilot to take inappropriate actions. Gary J Carr Delegate of the Civil Aviation Safety Authority 16 August 2004 The above AD is notified in the Commonwealth of Australia Gazette on 8 September 2004.
