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 US FAA has issued AD 2007-08-03 affecting Cessna 206 model aircraft. The USA is the State of Design for this type. CASA has assessed this AD and has issued Australian AD/CESSNA 206/62, Amendment 1, which will become effective on 25 April 2007. This AD cancels and replaces the previous issue.
As this AD is issued because of Australia’s obligations under Convention on International Civil Aviation, and because it is issued in response to an AD raised by the relevant State of Design, no consultation of the Australian public has taken place on this AD. The Office of Regulatory Review has determined that ADs do not require a Regulatory Impact Statement.
The AD has been made by the Manager, Airframes in the Manufacturing, Certification and New Technologies Office, 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, ensuring the safety and efficiency of air navigation. This Act empowers the Governor-General to make regulations that serve the interests of air navigation safety, as seen in the issuance of airworthiness directives under regulation 39.001 of the Civil Aviation Safety Regulations 1998. The Civil Aviation Safety Regulations 1998, in turn, allow the Civil Aviation Safety Authority (CASA) to issue these directives, which are critical for maintaining the continuing airworthiness of aircraft. These directives are legislative instruments, subject to disallowance and review as stipulated under the Acts Interpretation Act 1901 and the Legislative Instruments Act 2003. The Civil Aviation Act 1988, therefore, addresses the need for a robust regulatory system to uphold the safety standards mandated by international conventions such as the Convention on International Civil Aviation.
Scope and Application
The Civil Aviation Act 1988, as supplemented by the Civil Aviation Safety Regulations 1998, empowers the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) that apply to aircraft and aeronautical products in Australia. This authority is exercised in accordance with the requirements of Annex 8 to the Convention on International Civil Aviation, which mandates that the State of Design holds overall responsibility for the continuing airworthiness of aircraft types and must provide necessary information to the States of Registry, including Australia. Consequently, CASA is tasked with assessing and, if appropriate, issuing ADs that align with those issued by the State of Design, ensuring the continuing airworthiness of aircraft registered in Australia. For example, in response to the United States Federal Aviation Administration's AD 2007-08-03 concerning Cessna 206 model aircraft, CASA issued Australian AD/CESSNA 206/62, Amendment 1, which superseded the previous directive. This regulatory process does not require public consultation or a Regulatory Impact Statement, as it stems from international obligations and the specific mandate of the State of Design. The ADs are legislative instruments subject to disallowance under the Acts Interpretation Act 1901 and are issued by CASA in line with the Civil Aviation Act 1988.
Key Provisions
The Civil Aviation Act 1988, as amended by the Civil Aviation Safety Regulations 1998, provides the legislative framework for the issuance of airworthiness directives (ADs) in Australia. Under section 98 of the Act, the Governor-General has the authority to make regulations aimed at enhancing the safety of air navigation. Regulation 39.001 specifically empowers the Civil Aviation Safety Authority (CASA) to issue ADs for particular types of aircraft or aeronautical products. These ADs are essential for ensuring that aircraft maintain their airworthiness standards and comply with necessary safety requirements. According to subregulation 39.001(5), an AD is considered a disallowable instrument under section 46A of the Acts Interpretation Act 1901, and therefore, it qualifies as a legislative instrument as per section 6 of the Legislative Instruments Act 2003.
The obligations imposed by these regulations on CASA and other parties are substantial. CASA, as Australia's national airworthiness authority, must rigorously assess any ADs issued by the State of Design to ensure that the requirements meet the safety standards outlined in the Convention on International Civil Aviation. Specifically, Annex 8 to the Convention mandates that the State of Design has the primary responsibility for the continuing airworthiness of an aircraft type. This means that such states must provide all necessary information to ensure that their aircraft types remain airworthy. Similarly, the State of Registry of an individual aircraft is obligated to develop or adopt requirements that ensure the continuing airworthiness of that aircraft. When CASA receives an AD from a State of Design, it must evaluate the information and, if deemed necessary, issue a corresponding Australian AD to enforce the requirements set by the State of Design.
Failure to comply with the provisions of an AD can lead to significant legal consequences. Under the Civil Aviation Act 1988, any person who contravenes an AD is subject to strict penalties. These penalties are designed to enforce compliance and maintain the highest safety standards in aviation. Although the specific penalties are not detailed in the provided text, it is common for non-compliance to result in substantial fines and, in severe cases, criminal charges. The regulatory authority has the power to take enforcement actions to ensure that all aircraft meet the stipulated airworthiness requirements, thereby safeguarding the safety of all those involved in air travel.
The process of issuing an AD, as illustrated by the example of AD 2007-08-03 affecting Cessna 206 model aircraft, underscores the importance of international cooperation in aviation safety. The United States, as the State of Design for this type of aircraft, issued the initial AD, which CASA then assessed and subsequently issued as an Australian AD. This example highlights the seamless coordination between countries to address safety concerns and ensure that aircraft continue to meet the required safety standards. Although the AD was issued without public consultation due to its basis in international obligations, it has undergone thorough regulatory review to ensure its compliance with Australian safety requirements.
