CIVIL AVIATION ACT 1988
CIVIL AVIATION SAFETY REGULATIONS 1998
ISSUE OF AIRWORTHINESS DIRECTIVE
Under section 98 of the Civil Aviation Act 1988, the Governor-General may make regulations for the purposes of the Act and in the interests of the safety of air navigation. Under regulation 39.001 of the Civil Aviation Safety Regulations 1998, CASA may issue airworthiness directives (ADs) for kinds of aircraft or aeronautical products. Subregulation 39.001(5) of the Civil Aviation Safety Regulations 1998 provides that an AD is a disallowable instrument for the purposes of section 46A of the Acts Interpretation Act 1901. Therefore, in accordance with section 6 of the Legislative Instruments Act 2003, an AD is a legislative instrument.
Under Annex 8 to the Convention on International Civil Aviation, the State of Design has overall responsibility for continuing airworthiness of an aircraft type, and must provide any information necessary to ensure the continuing airworthiness of a type to appropriate States of Registry. ADs (and their equivalents) are the most common form of continuing airworthiness information, and are issued by most ICAO Contracting States.
The State of Registry of an individual aircraft is responsible for its continuing airworthiness. Under Annex 8, the State of Registry must develop or adopt requirements to ensure the continuing airworthiness of aircraft.
The Civil Aviation Safety Authority or its predecessors issued AD/DHC-2/14 affecting De Havilland DHC-2 (Beaver) model aeroplanes. CASA has assessed this AD and as a result has cancelled Australian AD/DHC-2/14. The cancellation will become effective on 23 October 2008. No replacement AD is required, as the unsafe condition no longer exists.
As this AD has been cancelled because of Australia’s obligations under the Convention on International Civil Aviation, no consultation with the Australian public has taken place on this AD cancellation. The Office of Best Practice Regulation has determined that ADs do not require a Regulatory Impact Statement.
The AD has been made by the Manager, Airframe and Structures, in the Airworthiness Engineering Group, on behalf of CASA, in accordance with subsection 84A (2) of the Act.
Overview
The Civil Aviation Act 1988 was enacted to govern civil aviation matters in Australia, ensuring the safety and efficiency of air navigation. It empowers the Governor-General to make regulations for the Act's purposes, particularly focusing on the safety of air navigation. Under this Act, the Civil Aviation Safety Regulations 1998 were established, which allow the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products, as per regulation 39.001. These directives serve as a crucial tool in maintaining the continuing airworthiness of aircraft, aligning with Australia's obligations under Annex 8 of the Convention on International Civil Aviation. The ADs are legislative instruments, subject to disallowance under section 46A of the Acts Interpretation Act 1901, and their creation is overseen by the Manager, Airframe and Structures, within CASA's Airworthiness Engineering Group, in accordance with the Act's provisions.
Scope and Application
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 together empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) concerning specific types of aircraft or aeronautical products, which are essential for maintaining safety in air navigation. These regulations apply to any entity involved in the operation or maintenance of aircraft within Australia, ensuring compliance with both national and international standards for airworthiness. The scope of this legislation extends to all aircraft registered in Australia, irrespective of the manufacturer's country of origin, and aligns with the obligations set forth in Annex 8 to the Convention on International Civil Aviation. While the Act and Regulations do not explicitly exclude any particular entities or types of aircraft from their purview, the practical application of ADs is subject to the authority's assessment and subsequent enforcement. Additionally, ADs are considered disallowable instruments, meaning they are subject to parliamentary scrutiny, and are treated as legislative instruments under the Legislative Instruments Act 2003. Given that ADs are a common mechanism for continuing airworthiness internationally, their issuance and cancellation reflect Australia's commitment to international aviation safety standards.
Key Provisions
The Civil Aviation Act 1988, particularly section 98, grants the Governor-General the authority to establish regulations aimed at ensuring the safety of air navigation. This overarching authority allows for the creation of specific rules and requirements that govern the aviation industry. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 empowers the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. These ADs are designed to address and rectify any issues that could potentially compromise the safety and airworthiness of the aircraft.
The obligations imposed by the Civil Aviation Safety Regulations 1998 on the parties governed by these regulations are quite stringent. Firstly, the State of Design, which is the country where the aircraft is designed, has the overarching responsibility for the continuing airworthiness of the aircraft type. This includes providing necessary information to ensure the safety of the aircraft to the State of Registry, which is the country where the aircraft is registered. Additionally, the State of Registry must establish or adopt requirements to ensure the continuing airworthiness of the aircraft under their jurisdiction. These responsibilities are in line with Annex 8 to the Convention on International Civil Aviation, which provides a framework for international cooperation in maintaining airworthiness standards.
Non-compliance with the provisions of the Civil Aviation Safety Regulations 1998, including the airworthiness directives, can lead to significant legal consequences. Under section 46A of the Acts Interpretation Act 1901, ADs are considered disallowable instruments, meaning that they can be reviewed and potentially disallowed by Parliament. Furthermore, failure to comply with an AD can result in serious safety risks, which may lead to enforcement actions by CASA. Although the specific penalties are not detailed in the provided text, it is reasonable to infer that non-compliance could result in both civil and criminal penalties, given the critical nature of airworthiness regulations.
It is important to note that the issuance and cancellation of ADs, such as the one affecting the De Havilland DHC-2 (Beaver) model aeroplanes, are made in accordance with Australia’s international obligations under the Convention on International Civil Aviation. This means that the decisions are often influenced by international standards and best practices. The Office of Best Practice Regulation has determined that ADs do not require a Regulatory Impact Statement, indicating that these measures are focused primarily on safety rather than economic considerations. The AD in question was made by the Manager, Airframe and Structures, in the Airworthiness Engineering Group, on behalf of CASA, in accordance with subsection 84A(2) of the Act, ensuring that the directive adheres to the legal framework established by the Civil Aviation Act 1988.
