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/CESSNA 500/21 affecting Cessna 500 and 501 model aeroplanes. CASA has assessed this AD and as a result has cancelled Australian AD/CESSNA 500/21. The cancellation will become effective on 25 September 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 legal framework for the regulation of civil aviation in Australia, with a primary focus on ensuring the safety of air navigation. Under this Act, the Governor-General is empowered to make regulations to achieve the objectives of the Act, and the Civil Aviation Safety Regulations 1998 further detail these regulatory measures. Specifically, regulation 39.001 allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for types of aircraft or aeronautical products, which are legislative instruments subject to disallowance under the Acts Interpretation Act 1901. These directives are crucial for maintaining the continuing airworthiness of aircraft, aligning with international standards set forth in Annex 8 to the Convention on International Civil Aviation. The State of Registry holds the responsibility for the ongoing airworthiness of individual aircraft, while the State of Design must provide necessary information to ensure the airworthiness of aircraft types. In this context, CASA has exercised its authority by cancelling AD/CESSNA 500/21, which previously affected Cessna 500 and 501 model aeroplanes, due to the resolution of the unsafe condition identified. The cancellation, effective from 25 September 2008, does not necessitate public consultation or a Regulatory Impact Statement, as determined by the Office of Best Practice Regulation. The directive was issued by the Manager, Systems and New Technologies, in the Airworthiness Engineering Group, on behalf of CASA, in accordance with the Act.
Scope and Application
The Civil Aviation Act 1988, along with the Civil Aviation Safety Regulations 1998, provides the legal framework for ensuring the safety of air navigation in Australia. Under section 98 of the Civil Aviation Act 1988, the Governor-General is empowered to make regulations for the purposes of the Act, ensuring the safety of air navigation, with the Civil Aviation Safety Regulations 1998 being an example of such regulations. Regulation 39.001 of these regulations grants the Civil Aviation Safety Authority (CASA) the authority to issue airworthiness directives (ADs) for certain types of aircraft or aeronautical products, which are legislative instruments under section 46A of the Acts Interpretation Act 1901 and the Legislative Instruments Act 2003. These directives are critical for maintaining the continuing airworthiness of aircraft, a responsibility that primarily lies with the State of Registry, which in Australia is CASA. ADs are also a common mechanism used by ICAO Contracting States to communicate continuing airworthiness information. This regulatory approach underscores Australia's commitment to international aviation safety standards as outlined in Annex 8 to the Convention on International Civil Aviation.
Key Provisions
The Civil Aviation Act 1988, particularly under section 98, empowers the Governor-General to enact regulations aimed at ensuring the safety of air navigation. This authority is exercised by the Civil Aviation Safety Authority (CASA) through regulation 39.001 of the Civil Aviation Safety Regulations 1998, which allows CASA to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. According to subregulation 39.001(5), an AD is classified as a disallowable instrument under section 46A of the Acts Interpretation Act 1901, and consequently, as a legislative instrument under section 6 of the Legislative Instruments Act 2003.
These airworthiness directives are essential tools for maintaining the continuing airworthiness of aircraft, a responsibility that primarily lies with the State of Design, as outlined in Annex 8 to the Convention on International Civil Aviation. The State of Design must provide necessary information to the States of Registry, which are responsible for ensuring the airworthiness of individual aircraft. In Australia, CASA has historically issued directives such as AD/CESSNA 500/21, which affected Cessna 500 and 501 models. However, CASA has since assessed and cancelled AD/CESSNA 500/21, effective 25 September 2008, due to the resolution of the unsafe condition it was intended to address. This cancellation does not necessitate a replacement directive, nor does it require public consultation, as determined by the Office of Best Practice Regulation, which found that ADs do not require a Regulatory Impact Statement.
Under the Civil Aviation Safety Regulations 1998, entities such as CASA and aircraft owners are bound by the obligations imposed by ADs. These obligations include compliance with the directives issued to maintain the airworthiness of aircraft, which may involve inspections, repairs, and modifications as specified in the ADs. Non-compliance with these directives can lead to severe consequences, including potential grounding of the aircraft and enforcement actions by CASA. The Civil Aviation Act 1988 also includes provisions for penalties and enforcement measures, although specific penalties are detailed in other regulations or legislative instruments.
Breaches of the Civil Aviation Safety Regulations 1998 can result in both civil and criminal consequences. For instance, under section 53 of the Civil Aviation Act 1988, failure to comply with an AD can result in significant fines and, in severe cases, imprisonment. The exact penalties depend on the nature and severity of the breach, but they can include substantial monetary fines for corporations and individuals alike. Additionally, CASA has the authority to take enforcement actions such as suspension or revocation of airworthiness certificates, which can have a profound impact on an aircraft operator’s ability to conduct commercial operations.
