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, the Civil Aviation Safety Authority (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.
CASA or its predecessors issued AD/CESSNA 170/25 affecting Cessna 172 model aircraft. CASA has reviewed this AD and as a result has cancelled it. The cancellation will become effective on 31 July 2008. No replacement AD is required.
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 Branch, on behalf of CASA, in accordance with subsection 84A (2) of the Act.
Overview
The Civil Aviation Act 1988, enacted by the Australian Parliament, is designed to ensure the safety and efficiency of civil aviation within Australia. This Act empowers the Governor-General to make regulations, such as the Civil Aviation Safety Regulations 1998, which are critical for maintaining air navigation safety. Under these regulations, the Civil Aviation Safety Authority (CASA) has the authority to issue airworthiness directives (ADs) for specific aircraft types or aeronautical products, as stated in regulation 39.001. These ADs are considered legislative instruments as per the Legislative Instruments Act 2003. The overarching goal of these measures is to align with international standards, particularly those outlined in Annex 8 of the Convention on International Civil Aviation, which mandates the State of Design to maintain the continuing airworthiness of aircraft types and provides necessary information to States of Registry.
In accordance with these international obligations, CASA has cancelled AD/CESSNA 170/25 concerning Cessna 172 model aircraft, effective from 31 July 2008. This decision was made in line with Australia's commitments under the Convention on International Civil Aviation, and as such, no public consultation or Regulatory Impact Statement was required. The cancellation was executed by the Manager, Systems and New Technologies, in the Airworthiness Engineering Branch, on behalf of CASA, in compliance with subsection 84A(2) of the Act.
Scope and Application
The Civil Aviation Act 1988, supplemented by the Civil Aviation Safety Regulations 1998, provides a legislative framework for the issuance of airworthiness directives (ADs) aimed at ensuring the safety of air navigation. The Act authorises the Governor-General to make regulations for air safety, and under regulation 39.001 of the Civil Aviation Safety Regulations 1998, the Civil Aviation Safety Authority (CASA) is empowered to issue ADs concerning specific types of aircraft or aeronautical products. These directives, as legislative instruments, are subject to disallowance and comply with the Legislative Instruments Act 2003. The ADs are integral to fulfilling international obligations under Annex 8 to the Convention on International Civil Aviation, where the State of Design has the responsibility for the continuing airworthiness of an aircraft type, while the State of Registry ensures the aircraft's ongoing airworthiness. Consequently, the AD/CESSNA 170/25 issued by CASA or its predecessors concerning Cessna 172 model aircraft was reviewed and subsequently cancelled effective 31 July 2008, due to Australia’s international obligations, without the need for public consultation or a Regulatory Impact Statement.
Key Provisions
The main operative sections of this legislation are sections 98 and 39.001 of the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 respectively. Section 98 allows the Governor-General to make regulations for the purposes of the Act, focusing on the safety of air navigation. Section 39.001 permits the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific kinds of aircraft or aeronautical products. Subregulation 39.001(5) further clarifies that an AD is a disallowable instrument under section 46A of the Acts Interpretation Act 1901, and thus a legislative instrument under section 6 of the Legislative Instruments Act 2003. These sections empower CASA to issue directives to ensure the safety and airworthiness of aircraft.
The obligations imposed by these sections require CASA to issue ADs as necessary to maintain the safety and airworthiness of aircraft. The State of Design has the overarching responsibility to ensure the continuing airworthiness of an aircraft type, providing necessary information to the States of Registry. The State of Registry, in turn, must develop or adopt requirements to ensure the continuing airworthiness of individual aircraft. This dual responsibility ensures that all stakeholders, including manufacturers and regulatory authorities, work together to maintain high safety standards. CASA, as the regulatory authority in Australia, must comply with these obligations by issuing and monitoring ADs, and ensuring that aircraft meet the necessary safety standards.
Breaching the obligations set out by these regulations can lead to significant consequences. Failure to comply with ADs can result in penalties for non-compliance, which could include civil or criminal penalties. For example, under the Civil Aviation Act 1988, non-compliance with an AD can lead to fines and other penalties. The exact penalties depend on the severity of the breach and may be subject to the maximum penalties specified under the Act or related regulations. Such penalties serve as a deterrent against non-compliance, ensuring that all parties adhere to the necessary safety standards.
The Civil Aviation Safety Regulations 1998, along with the Civil Aviation Act 1988, provide a comprehensive framework for ensuring the safety and airworthiness of aircraft in Australia. By issuing ADs, CASA plays a crucial role in maintaining these standards. The regulatory process ensures that all stakeholders are aware of their responsibilities and the consequences of non-compliance, thereby promoting a safe and reliable aviation environment. This framework, backed by clear obligations and penalties, ensures that the aviation industry adheres to the highest safety standards.
