AD/AUS/1 - Lift Strut

Overview

The Civil Aviation Regulations 1998, enacted by the Parliament of Australia, constitute a comprehensive regulatory framework governing the safety and operational standards within the civil aviation sector. One of the legislative instruments under this Act is the Civil Aviation Safety Authority Schedule of Airworthiness Directives, specifically addressing the Auster/Beagle A.61 Series Aeroplanes. This directive, numbered AD/AUS/1, was introduced to tackle the specific issue of lift struts in aeroplanes manufactured before May 1947, mandating compliance with the instructions outlined in Auster Service Bulletins Issues 2 and 5. The policy objective behind these regulations is to ensure the ongoing airworthiness and safety of aircraft through timely and effective maintenance and compliance actions. The enactment of these regulations by the Civil Aviation Safety Authority aims to maintain and enhance the safety standards of civil aviation, addressing the identified gap in the maintenance requirements for older aeroplane models. By specifying mandatory actions and compliance timelines, the regulations seek to mitigate risks associated with the identified issues, thereby contributing to the overall safety and reliability of civil aviation operations in Australia.

Scope and Application

The Civil Aviation Regulations 1998, specifically within Part 39 - 105, sets out detailed safety directives concerning Auster/Beagle A.61 series aeroplanes, targeting models manufactured before May 1947. This legislation applies to all aeroplanes of the specified series and models, mandating compliance with the safety directives to ensure airworthiness. The regulation extends its jurisdictional reach throughout the Commonwealth of Australia, imposing stringent safety standards that must be adhered to by the operators and owners of these aircraft. The directive necessitates immediate action in accordance with Auster Service Bulletins Issues 2 and 5 to address the lift strut, highlighting the importance of compliance without any delay. The regulation does not provide explicit exclusions or exemptions within its text, suggesting that all affected aircraft must meet the specified requirements to maintain their airworthiness certificates. While the primary text does not explicitly mention extensions or restrictions through subordinate instruments, the regulation's framework allows for further clarification or additional requirements through amendments or supplementary directives issued by the Civil Aviation Safety Authority.

Key Provisions

The Civil Aviation Regulations 1998, specifically Part 39 - 105, establishes the authority and requirements for issuing airworthiness directives under the Civil Aviation Safety Authority (CASA). Section 39.105 addresses the applicability of these directives to specific aircraft models, in this case, Auster/Beagle A.61 Series aeroplanes. The directive AD/AUS/1 mandates that all models of these aeroplanes manufactured before May 1947 must comply with the requirements outlined in Auster Service Bulletins Issues 2 and 5 regarding the lift strut. Compliance with these directives must be achieved immediately, referred to as "forthwith" in the regulation (39.105). The obligations imposed by these regulations are clear and straightforward. Owners and operators of Auster/Beagle A.61 Series aeroplanes that fall within the specified manufacturing date must ensure that their aircraft meet the specified service bulletin requirements. This involves adhering to the detailed instructions and modifications provided in Auster SB Issues 2 and 5 to ensure the lift strut is in a safe and compliant condition. Failure to comply with these service bulletins and achieve the required modifications promptly can result in the aircraft being deemed non-airworthy, thereby prohibiting its operation until the issues are rectified. Violating these airworthiness directives can have serious consequences. According to the Civil Aviation Regulations, non-compliance with an airworthiness directive can be considered an offence under the Civil Aviation Act 1988. Specifically, an individual or corporation that fails to comply with a directive may face substantial penalties. For a corporation, the maximum penalty can be up to $1,008,000, while an individual may face a penalty of up to $201,600 (as per Section 17(1) of the Civil Aviation Act 1988). Additionally, CASA has the authority to take enforcement actions, which may include grounding the aircraft or imposing operational restrictions until compliance is achieved. These stringent measures underscore the importance of adhering to the airworthiness directives to maintain the highest safety standards in civil aviation.
