Cessna 180, 182 and Wren 460 Series Aeroplanes

AD/CESSNA 180/83 (continued)

Compliance: For Requirement 1 - Within 100 hours time in service after the effective date of this Directive.

For Requirement 2 - Before further flight after installing the update to the KC 140 autopilot computer system operating software.

For Requirement 3 - As of the effective date of this Directive.

This Airworthiness Directive becomes effective on 19 February 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.

This Directive requires 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.
