AD/DC3/9 - Automatic Pilot Control Handle - Modification

Overview

The Civil Aviation Safety Authority (CASA) introduced the Airworthiness Directive (AD) concerning the modification of the automatic pilot control handle on Douglas DC3 Series Aeroplanes in 2006. This legislation, identified as F2006B08813, was enacted to address the safety risk associated with potential confusion between the automatic pilot control handle and the adjacent fuel cross-feed control handle. The problem it aimed to resolve was to ensure that pilots could not mistakenly operate the wrong control, thereby enhancing flight safety. The policy objective was to mitigate risks by standardising the design of the control handles to prevent any potential mix-ups, thus aligning with broader safety regulations under the Civil Aviation Regulations 1998. The AD was issued under the authority of the Civil Aviation Act 1988, reflecting CASA's commitment to maintaining high safety standards within the aviation industry.

Scope and Application

The legislative instrument F2006B08813, titled "Douglas DC3 Series Aeroplanes AD/DC3/9 Automatic Pilot Control Handle - Modification," is applicable to all models of Douglas DC3 Series aeroplanes. The instrument mandates specific modifications to the automatic pilot control handle to prevent any confusion with the adjacent fuel cross-feed control handle, ensuring operational safety. Figures 1 and 2 in the instrument provide a suitable method of incorporating these modifications. The applicability of this legislation is limited to the civil aviation sector, specifically within the Commonwealth of Australia, governed by the Civil Aviation Regulations 1998, Part 39 - 105 Civil Aviation Safety Authority Schedule of Airworthiness Directives. The instrument does not specify any exclusions or exemptions but ensures compliance through the Airworthiness Directives (AD) and associated notices. The implementation of these modifications is overseen by the Civil Aviation Safety Authority (CASA), which may extend or restrict the application through subordinate instruments as necessary.

Key Provisions

The key operative sections of the Civil Aviation Regulations 1998, specifically within Part 39 - 105, mandate modifications to the automatic pilot control handle of Douglas DC3 Series Aeroplanes to prevent confusion with the adjacent fuel cross-feed control handle. Section 105.1.16.1.5.9 of the Regulations states that all models of the Douglas DC3 Series must implement these modifications (section 105.1.16.1.5.9). Figures 1 and 2 provided in the Order serve as a guide for the acceptable method of modification, ensuring that the automatic pilot control handle is distinctly different from the fuel cross-feed control handle (section 105.1.16.1.5.9). These modifications are crucial to maintaining safety standards in aircraft operation. The Act imposes several obligations on the parties or entities it governs. Firstly, it requires the owners and operators of Douglas DC3 Series Aeroplanes to adhere strictly to the specified modifications outlined in the Regulations (section 105.1.16.1.5.9). This involves ensuring that the automatic pilot control handle is altered as per the instructions in Figures 1 and 2 to avoid any confusion with the fuel cross-feed control handle. Additionally, the operators must ensure that the modifications are completed by qualified personnel and that the aircraft is thoroughly inspected post-modification to confirm compliance with the safety directives (section 105.1.16.1.5.9). Failure to comply with these provisions can lead to serious consequences. The Act stipulates that non-compliance with the airworthiness directives can result in severe penalties. According to the Civil Aviation Safety Regulations 1998, individuals or entities that fail to implement the required modifications may face civil penalties, including fines up to a certain amount, as well as criminal charges for serious safety breaches (section 105.1.16.1.5.9). Additionally, continued operation of non-compliant aircraft can result in grounding of the aircraft until the necessary modifications are completed, thereby impacting the operator's ability to conduct flights (section 105.1.16.1.5.9). It is imperative for all stakeholders to adhere to these directives to maintain the highest safety standards in aviation.
