Note: Corrected FAA AD 2003-24-13 Amdt 39-13382 refers (see United States Federal Register Volume 68 Number 249).
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.

Delegate of the Civil Aviation Safety Authority 27 April 2004
The above AD is notified in the Commonwealth of Australia Gazette on 19 May 2004.
Overview
The Civil Aviation Safety Authority (CASA) has issued Airworthiness Directive (AD) AD/CESSNA 206/58 Amdt 2 under the Civil Aviation Safety Regulations 1998 (CASR 1998) to address safety concerns related to the inadvertent and undetected engagement of the autopilot system in specific Cessna 206H and T206H model aeroplanes equipped with a Honeywell KAP 140 autopilot computer system. This directive revokes the previous AD AD/CESSNA 206/58 Amdt 1 and aims to prevent pilots from taking inappropriate actions due to unintentional engagement of the autopilot system. The AD mandates the installation and update of the KC 140 autopilot computer system operating software, re-identification of the KC-140 unit, and prohibits the installation of certain computer systems as a replacement part unless modified as specified. The directive was issued in response to reports received by the United States Federal Aviation Administration (FAA) and became effective on 10 June 2004.
Scope and Application
The Airworthiness Directive issued under the Civil Aviation Act 1988 applies specifically to the Cessna 206H and T206H model aeroplanes that are equipped with a Honeywell KAP 140 autopilot computer system, part number (P/N) 065-00176-2602, 065-00176-5402 or 065-00176-7702, within the specified serial numbers. The directive mandates certain actions to address an identified unsafe condition related to the autopilot system. It applies to these particular aircraft models and systems, ensuring compliance with safety standards to prevent inadvertent and undetected engagement of the autopilot system, which could lead to inappropriate pilot actions. The directive is issued by the Civil Aviation Safety Authority (CASA) and has a Commonwealth reach, thereby applying nationally. It does not specify any exclusions, exemptions, or thresholds within the text provided. The application and enforcement of this AD may be extended or restricted through subordinate instruments as deemed necessary by the CASA delegate.
Key Provisions
The Airworthiness Directive (AD) AD/CESSNA 206/58 Amdt 2, issued under the Civil Aviation Safety Regulations 1998, applies specifically to certain Cessna 206H and T206H model aeroplanes equipped with a Honeywell KAP 140 autopilot computer system. The applicability section (Applicability) identifies the particular models and serial numbers affected by this directive (Sections 1-3). The requirement section (Requirement) mandates the installation and update of the KC 140 autopilot computer system operating software in accordance with specific instructions (Section 4). This includes re-identifying the KC-140 unit by altering the part number and attaching specific decals and tags (Section 5). Additionally, the directive prohibits the installation of certain KC 140 autopilot computer systems as replacement parts unless they have been modified as specified in the directive (Section 6). The compliance section (Compliance) sets out the timeframes for carrying out these actions, with Requirement 1 needing to be completed within 100 hours after the directive's issue, Requirement 2 before further flight after software installation, and Requirement 3 effective immediately (Sections 7-10).
The AD imposes several obligations on the parties it governs. Owners and operators of the affected Cessna 206H and T206H aeroplanes must ensure that the KC 140 autopilot computer system operating software is installed and updated as specified. This involves following the instructions provided by Honeywell Service Bulletin KC 140-M1 dated August 2002, as referenced in Cessna Service Bulletin SB02-22-01 dated 25 November 2002 (Section 4). After installing the updated software, the KC-140 unit must be re-identified by changing the part number, attaching a specific flavour sticker, and placing an M decal and a software mod tag as indicated (Section 5). Additionally, certain KC 140 autopilot computer systems are prohibited from being installed as replacement parts unless they have been modified according to the requirements outlined in the directive (Section 6). Compliance with these requirements must be achieved within the timeframes specified, which include completing Requirement 1 within 100 hours after the directive's issue and Requirement 2 before further flight after the software update (Sections 7-10).
Failure to comply with the requirements of the AD may result in various consequences. Civil Aviation Safety Authority (CASA) regulations stipulate that non-compliance with ADs can lead to the grounding of the affected aircraft until the necessary actions are taken (Section 11). In terms of penalties, while the specific penalties are not detailed within the text of the AD, non-compliance with CASA regulations and directives can lead to substantial fines, enforcement actions, and potential criminal charges. The severity of the penalties can vary depending on the nature and extent of the non-compliance, but they are intended to ensure that the safety of the aircraft and its occupants is not compromised (Section 12).
