Cessna 206 Series Aeroplanes

AD/CESSNA 206/58 Amdt 2 (continued)

Compliance: For Requirement 1 - Remains unchanged as ‘Within 100 hours time in service after the effective date of the original issue 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 - Remains unchanged as ‘As of the effective date of the original issue of this Directive’.

This Amendment becomes effective on 10 June 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.

The 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.

Amendment 1 corrected an anomaly in the T206H serial number range and continued the requirements of the original issue of the Directive.

This Amendment is issued to correct a grammatical error and has no other effect.

The original issue of this Airworthiness Directive became effective on 19 February 2004.

Amendment 1 became effective 18 March 2004.
