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 2008-11-17 affecting Air Tractor AT-600 model aircraft. The USA is the State of Design for this type. CASA has assessed this AD and has issued Australian AD/AT 600/8 which will become effective on 31 July 2008.
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 Best Practice Regulation has determined that ADs do not require a Regulatory Impact Statement.
The AD has been made by the Manager, Airframes in the Airworthiness Engineering Branch, on behalf of CASA, in accordance with subsection 84A (2) of the Act.
Overview
The Civil Aviation Act 1988 was enacted to regulate the safety and efficiency of civil aviation in Australia, with a particular focus on ensuring the safety of air navigation. The Act empowers the Governor-General to make regulations that serve the interests of aviation safety, and these regulations include provisions for the issuance of airworthiness directives (ADs) under regulation 39.001 of the Civil Aviation Safety Regulations 1998. These ADs are legislative instruments that address continuing airworthiness concerns for specific types of aircraft or aeronautical products, as mandated by Annex 8 to the Convention on International Civil Aviation. The Civil Aviation Safety Authority (CASA) is responsible for assessing and issuing Australian ADs when necessary, following evaluations of ADs issued by the relevant State of Design. In this particular instance, CASA issued AD/AT 600/8 in response to an AD issued by the US Federal Aviation Administration concerning Air Tractor AT-600 model aircraft, reflecting Australia's commitment to international aviation safety standards.
Scope and Application
The Civil Aviation Safety Regulations 1998, under section 39.001, empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific kinds of aircraft or aeronautical products in accordance with section 98 of the Civil Aviation Act 1988. These ADs are legislative instruments as they are disallowable instruments under section 46A of the Acts Interpretation Act 1901 and are regulated by the Legislative Instruments Act 2003. ADs are essential for ensuring the continuing airworthiness of aircraft types and are typically issued by the State of Design, with the State of Registry being responsible for implementing these directives. In this context, Australia, through CASA, assesses and issues ADs in response to international directives, such as the AD 2008-11-17 from the US Federal Aviation Administration (FAA) concerning Air Tractor AT-600 model aircraft. CASA's AD/AT 600/8, issued under the Act, reflects Australia's obligations under the Convention on International Civil Aviation and mandates specific requirements for the Australian Register. Given their nature, ADs typically do not undergo public consultation or require a Regulatory Impact Statement, as determined by the Office of Best Practice Regulation. The AD is issued by the Manager, Airframes in the Airworthiness Engineering Branch on behalf of CASA, in compliance with subsection 84A(2) of the Act.
Key Provisions
The Civil Aviation Act 1988, under section 98, allows the Governor-General to establish regulations aimed at ensuring the safety of air navigation. This authority is exercised through the Civil Aviation Safety Regulations 1998, particularly under regulation 39.001, which empowers the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. These ADs are legislative instruments, as outlined in subregulation 39.001(5), and are subject to disallowance under section 46A of the Acts Interpretation Act 1901. Furthermore, they are regulated as legislative instruments under section 6 of the Legislative Instruments Act 2003. This regulatory framework ensures that ADs, which are essential for maintaining the continuing airworthiness of aircraft, are issued in compliance with international standards.
The obligations under this Act and its regulations are multifaceted and involve various entities. Primarily, the State of Design, which in this case is the USA for the Air Tractor AT-600 model aircraft, is responsible for ensuring that any information necessary for the continuing airworthiness of the aircraft type is provided to the States of Registry, such as Australia. CASA, as the national airworthiness authority for Australia, is then responsible for assessing this information and, if deemed necessary, issuing an Australian AD to enforce the requirements outlined by the State of Design. This process ensures that the aircraft registered in Australia meet the international safety standards set forth by ICAO under Annex 8 of the Convention on International Civil Aviation.
Under the Civil Aviation Safety Regulations 1998, failure to comply with an AD can result in severe consequences. Although specific offences and penalties are not detailed in the provided text, non-compliance with ADs can typically lead to significant civil or criminal penalties. Such penalties may include fines, imprisonment, or both, depending on the severity of the breach and the discretion of the court. The consequences underscore the importance of adhering to ADs to maintain the safety of air navigation and the integrity of the aviation regulatory framework.
In summary, the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 establish a comprehensive regulatory framework for issuing airworthiness directives. These regulations are critical for ensuring that aircraft meet international safety standards and that the continuing airworthiness of aircraft types is maintained. CASA's role in assessing and issuing Australian ADs in response to directives from States of Design, such as the USA, ensures that Australian-registered aircraft comply with necessary safety requirements. The legal obligations and potential penalties for non-compliance reinforce the importance of adhering to these directives to safeguard air navigation safety.
