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 United States FAA issued AD 87-21-07 affecting Gulfstream 500, 600 and 700 series aircraft. The United States is the State of Design for these aircraft. CASA has assessed this AD and as a result has cancelled Australian AD/AC/101. The cancellation will become effective on 23 October 2008. No replacement AD is required, as the original unsafe condition has been corrected by existing CASA rules.
As this AD has been cancelled because of Australia’s obligations under the Convention on International Civil Aviation, and because it is cancelled in response to an AD raised by the relevant State of Design, no consultation with the Australian public has taken place on this AD cancellation. The Office of Regulatory Review 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 within Australia, aiming to ensure the safety and efficiency of air navigation. This Act empowers the Governor-General to make regulations in the interests of air navigation safety, including the issuance of airworthiness directives by the Civil Aviation Safety Authority (CASA) as stipulated in the Civil Aviation Safety Regulations 1998. The policy objective of the Act is to maintain high standards of safety and efficiency in civil aviation through stringent regulatory oversight and adherence to international standards set by the International Civil Aviation Organization (ICAO). In response to the obligations under the Convention on International Civil Aviation, the Civil Aviation Act enables CASA to issue and manage airworthiness directives, ensuring the continuing airworthiness of aircraft registered in Australia by aligning with directives issued by the aircraft's State of Design.
Scope and Application
The Civil Aviation Act 1988, as amended by the Civil Aviation Safety Regulations 1998, provides the framework for the issuance of airworthiness directives (ADs) to ensure the safety of aircraft and aeronautical products. Under this legislative framework, the Civil Aviation Safety Authority (CASA) is empowered to issue ADs for specific types of aircraft or aeronautical products, as stipulated in regulation 39.001 of the Civil Aviation Safety Regulations 1998. These ADs are considered legislative instruments as per the Legislative Instruments Act 2003, which means they have legal effect and can be disallowed under the Acts Interpretation Act 1901. The ADs serve as a means to communicate necessary information to ensure the continuing airworthiness of aircraft, in line with obligations under Annex 8 of the Convention on International Civil Aviation. The State of Registry, in this case CASA, is responsible for ensuring that aircraft registered in Australia meet the continuing airworthiness requirements, which includes implementing ADs issued by the relevant State of Design, such as the United States for certain Gulfstream aircraft series. This process ensures compliance with international standards and the safety of air navigation within Australia's jurisdiction.
Key Provisions
The main operative sections of the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 detail the authority and process for issuing airworthiness directives (ADs). Section 98 of the Act allows the Governor-General to make regulations for the safety of air navigation, while regulation 39.001 of the Regulations empowers the Civil Aviation Safety Authority (CASA) to issue ADs for specific aircraft or aeronautical products. Furthermore, subregulation 39.001(5) classifies an AD as a disallowable instrument, thus a legislative instrument under the Legislative Instruments Act 2003.
The obligations imposed by the Act and Regulations focus on ensuring the continuing airworthiness of aircraft. The State of Design, as per Annex 8 to the Convention on International Civil Aviation, is responsible for providing necessary information to ensure the airworthiness of a particular aircraft type. CASA, as Australia’s national airworthiness authority, must review this information and issue a corresponding Australian AD if deemed necessary. This process ensures that Australian aircraft comply with international standards and safety requirements.
In terms of potential breaches and consequences, the Civil Aviation Act 1988 does not explicitly detail specific offences or penalties for non-compliance with ADs. However, general compliance with ADs is mandatory, and failure to adhere to these directives could lead to significant safety risks, potentially resulting in aircraft being grounded or other enforcement actions. While specific penalties are not outlined in the provided text, non-compliance could potentially lead to administrative, civil, or criminal penalties under broader aviation safety laws, which may include fines or imprisonment depending on the severity of the breach.
The legislative framework ensures that ADs are issued to maintain safety standards and that the process adheres to international obligations and domestic regulations. The cancellation of an AD, as in the case of Gulfstream 500, 600, and 700 series aircraft, is based on assessments by CASA and the State of Design, ensuring that safety conditions are met and that the aircraft can continue to operate safely. The absence of a Regulatory Impact Statement and public consultation in this context is justified by the nature of the AD cancellation, which aligns with international obligations and does not necessitate broader public consultation.
