Requirement: 1. Inspect the left and right wing aileron control bellcrank stop bolts and lock nuts for flush and tight contact with the surface of the threaded boss on each end of the yoke assemblies as detailed in the instructions published in Cessna Special Service Project SSP99-27-02 dated 18 May 1999.
2. Following the inspection at Requirement 1 above, perform follow on and corrective action on all aircraft as detailed in the instructions published in Cessna Special Service Project SSP99-27-02 dated 18 May 1999.
Note: US FAA AD 99-13-04 Amdt 39-11197 dated 18 June 1999 refers.
Compliance: 1. Within the next 10 hours time in service or within 60 days of the effective date of this Directive whichever occurs sooner.

This Airworthiness Directive become effective on 7 July 1999.
Background: An unsafe condition has been found during the inspection of a Cessna 206H that could exist in other serial number aircraft with the same aileron system design. The situation could lead to partial or complete loss of aileron control and so a safety of flight Airworthiness Directive has been issued by the FAA to inspect all such aileron systems. This Directive reflects the content and urgency of the US FAA AD.
Overview
The Civil Aviation Regulations 1998, as amended, are the primary legislative instrument governing civil aviation in Australia, established to ensure the safety and efficiency of civil aviation operations. Within this framework, Part 39, particularly Schedule 105, outlines specific airworthiness directives to address identified safety issues. One such directive, AD/CESSNA 206/50, was introduced in 1999 by the Civil Aviation Safety Authority (CASA), in response to a safety issue identified in certain Cessna 206 Series aeroplanes. This directive aims to mitigate the risk of partial or complete loss of aileron control, which could compromise flight safety. The directive requires an inspection of the aileron control bellcrank stop bolts and lock nuts, with corrective actions to be implemented as necessary, reflecting the urgency and safety imperatives set forth by the US Federal Aviation Administration’s corresponding directive.
Scope and Application
The Airworthiness Directive (AD) AD/CESSNA 206/50 under the Civil Aviation Regulations 1998 applies specifically to Cessna 206H and T206H series aeroplanes within the specified serial number ranges. The directive mandates a rigorous inspection of the left and right wing aileron control bellcrank stop bolts and lock nuts to ensure they maintain a flush and tight contact with the threaded boss on each end of the yoke assemblies. This requirement is underpinned by detailed instructions published in Cessna Special Service Project SSP99-27-02 dated 18 May 1999. The directive is issued to mitigate the risk of partial or complete loss of aileron control, thereby ensuring the safety of flight. Compliance with this directive must occur within the next 10 hours of time in service or within 60 days of the directive's effective date of 7 July 1999, whichever is sooner, and before the next flight. This directive reflects the urgency and content of the corresponding US Federal Aviation Administration AD 99-13-04 Amdt 39-11197 dated 18 June 1999.
Key Provisions
The Civil Aviation Regulations 1998, specifically Part 39 - 105, addresses the safety of aircraft and includes detailed airworthiness directives for various aircraft models. One such directive, AD/CESSNA 206/50, pertains to the Cessna 206 Series aeroplanes and mandates specific inspections and corrective actions for certain models and serial numbers (Part 39 - 105). The directive applies to Model 206H serial numbers ranging from 20608002 through 20608026, and T206H aeroplanes with serial numbers from T20608002 through T20608015, T20608017 through T20608023, and T20608025 through T20608028 (Part 39 - 105). This directive was issued due to an identified unsafe condition that could lead to partial or complete loss of aileron control.
Under the directive, the key requirement is to inspect the left and right wing aileron control bellcrank stop bolts and lock nuts to ensure they are flush and in tight contact with the threaded boss on each end of the yoke assemblies (Part 39 - 105). This inspection must be carried out according to the instructions provided in Cessna Special Service Project SSP99-27-02 dated 18 May 1999. Following the inspection, any necessary corrective actions must be implemented as detailed in the same instructions (Part 39 - 105). The directive references a US FAA AD 99-13-04 Amdt 39-11197 dated 18 June 1999, indicating alignment with international safety standards.
Compliance with this directive requires that the inspections and corrective actions be completed within the next 10 hours of time in service or within 60 days from the effective date of the directive, whichever is sooner (Part 39 - 105). Additionally, all actions must be completed before the next flight. The directive became effective on 7 July 1999, underscoring the urgency and importance of adhering to these safety measures to prevent potential loss of aileron control.
Failure to comply with the requirements of this airworthiness directive could result in serious safety issues, including partial or complete loss of aileron control, which could compromise the safety of flight. While the specific penalties for non-compliance are not detailed within the directive, general provisions under the Civil Aviation Act 1988 may apply, potentially including fines and other civil or criminal consequences for breaches of airworthiness requirements.
