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. When a State of Design issues an AD against a type of aircraft on the Australian Register, CASA, as Australia’s national airworthiness authority, must assess that information and, if appropriate, issue an Australian AD to mandate the requirements of the State of Design.
The Civil Aviation Safety Authority or its predecessors issued AD/CESSNA 206/34 affecting Cessna 206 model aircraft. CASA has assessed this AD and as a result has cancelled it. 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, Systems and New Technologies 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 provide a comprehensive framework for the regulation of civil aviation in Australia, focusing on ensuring the safety of air navigation. Under this Act, the Governor-General has the authority to create regulations that support the overarching aim of aviation safety. Specifically, 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 directives serve as crucial tools for maintaining the continuing airworthiness of aircraft in accordance with international standards, as outlined in Annex 8 to the Convention on International Civil Aviation. The AD/CESSNA 206/34, issued and subsequently cancelled by CASA, is an example of how these regulations are applied to ensure the safety and compliance of aircraft within the Australian Register. The cancellation of this directive, effective from 23 October 2008, highlights CASA's commitment to adhering to international obligations and maintaining high safety standards.
Scope and Application
The Civil Aviation Act 1988, supported by the Civil Aviation Safety Regulations 1998, provides the legislative framework for the regulation of civil aviation in Australia. Specifically, under section 98 of the Act, the Governor-General has the authority to make regulations for the purposes of the Act, which is to ensure the safety of air navigation. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 grants the Civil Aviation Safety Authority (CASA) the power to issue airworthiness directives (ADs) for specified types of aircraft or aeronautical products. These ADs are considered legislative instruments under the Legislative Instruments Act 2003, as they are disallowable instruments under the Acts Interpretation Act 1901. This regulatory mechanism applies to the State of Registry of an individual aircraft, which is responsible for the continuing airworthiness of the aircraft, and aligns with the responsibilities outlined in Annex 8 to the Convention on International Civil Aviation. The State of Design of an aircraft type has a corresponding responsibility for the continuing airworthiness of that type, and must provide necessary information to the State of Registry. The ADs issued by CASA serve to implement these international standards within Australia, ensuring compliance with both national and international aviation safety requirements.
Key Provisions
The Civil Aviation Act 1988, specifically under section 98, grants the Governor-General the authority to make regulations necessary for the safety of air navigation. This power extends to the issuance of airworthiness directives (ADs) as per regulation 39.001 of the Civil Aviation Safety Regulations 1998, which allows the Civil Aviation Safety Authority (CASA) to issue ADs for specific kinds of aircraft or aeronautical products. These ADs serve as legislative instruments under subregulation 39.001(5) and are subject to disallowance as per section 46A of the Acts Interpretation Act 1901. Furthermore, according to Annex 8 of the Convention on International Civil Aviation, the State of Design holds the primary responsibility for ensuring the continuing airworthiness of an aircraft type, which includes providing necessary information to States of Registry to maintain safety standards.
In terms of obligations, CASA, as Australia's national airworthiness authority, must review and assess any ADs issued by the State of Design concerning aircraft registered in Australia. If an AD is deemed necessary to address a safety issue, CASA is required to issue a corresponding Australian AD to mandate compliance with the safety requirements. This process ensures that Australian-registered aircraft meet international safety standards and obligations. For instance, in the case of AD/CESSNA 206/34 concerning Cessna 206 model aircraft, CASA assessed the AD and subsequently cancelled it because the unsafe condition no longer existed. The cancellation was made effective on 23 October 2008, and no replacement AD was necessary.
The legislation also imposes specific requirements and processes for the issuance and cancellation of ADs. CASA must act in accordance with the Civil Aviation Act 1988, particularly under subsection 84A(2), when issuing or cancelling ADs. This process is conducted by the Manager, Systems and New Technologies within the Airworthiness Engineering Group. Importantly, the Office of Best Practice Regulation has determined that ADs do not require a Regulatory Impact Statement, and the cancellation of an AD, such as AD/CESSNA 206/34, does not necessitate public consultation due to Australia's obligations under the Convention on International Civil Aviation.
For breaches of the Civil Aviation Act 1988 or the Civil Aviation Safety Regulations 1998, including non-compliance with ADs, there are potential civil and criminal consequences. Penalties can include substantial fines and, in severe cases, imprisonment. The exact penalties depend on the nature and severity of the breach, but they are designed to enforce compliance and maintain the highest safety standards in civil aviation. This stringent approach ensures that all parties, including aircraft manufacturers, operators, and regulatory authorities, adhere to the prescribed safety regulations.
