CIVIL AVIATION ACT 1988
CIVIL AVIATION 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 Netherlands CAA has issued AD CAA-NL 2004-159 affecting Fokker F100 model aircraft. The Netherlands is the State of Design for this type. CASA has assessed this AD and has issued Australian AD/F100/63, which will become effective on 12 May 05.
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 Section Head - Airframes, Airworthiness Standards Branch, Standards Division, on behalf of CASA, in accordance with subsection 84A (2) of the Act.
Overview
The Civil Aviation Act 1988 was enacted to regulate and ensure the safety of air navigation within Australia. The Act empowers the Governor-General to make regulations that are essential for maintaining the safety of air navigation. A significant component of these regulations includes the issuance of airworthiness directives (ADs) under the Civil Aviation Safety Regulations 1998, specifically regulation 39.001. These directives serve as a critical mechanism for ensuring that aircraft and aeronautical products maintain their airworthiness. The Civil Aviation (Administrative and Support) Amendment Regulations 2005, which fall under the purview of the Civil Aviation Act, mandate that ADs are legislative instruments and can be disallowed under the Acts Interpretation Act 1901. This legislative framework is designed to align with international standards, particularly those outlined in Annex 8 to the Convention on International Civil Aviation, which mandates that the State of Design holds primary responsibility for the continuing airworthiness of an aircraft type. In response to international obligations and the issuance of ADs by the State of Design, the Civil Aviation Safety Authority (CASA) is tasked with assessing and, if necessary, issuing corresponding Australian ADs to ensure compliance and safety within the Australian aviation sector.
Scope and Application
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 collectively establish the framework for issuing airworthiness directives (ADs) in Australia. Under these legislative instruments, the Civil Aviation Safety Authority (CASA) is empowered to issue ADs for specific kinds of aircraft or aeronautical products, ensuring adherence to safety standards. Such ADs serve as legislative instruments, subject to disallowance and review as per the Acts Interpretation Act 1901 and the Legislative Instruments Act 2003. The authority to issue these directives is grounded in international obligations under Annex 8 to the Convention on International Civil Aviation, which designates the State of Design as responsible for the continuing airworthiness of aircraft types. In Australia, CASA, acting as the national airworthiness authority, assesses and issues Australian ADs in response to directives from the relevant State of Design. The ADs are designed to mandate the necessary safety requirements to maintain airworthiness and are applied to aircraft registered within Australia. Given their international nature and the urgency often associated with safety directives, these ADs are typically issued without public consultation and do not require a Regulatory Impact Statement, streamlining the process to swiftly address safety concerns.
Key Provisions
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998, particularly section 98 and regulation 39.001 respectively, establish the framework for the issuance of airworthiness directives (ADs) by the Civil Aviation Safety Authority (CASA). Under section 39.001(5) of the Civil Aviation Safety Regulations 1998, these ADs are classified as disallowable instruments, meaning they can be reviewed and potentially disallowed by Parliament. Furthermore, these directives are also legislative instruments according to section 6 of the Legislative Instruments Act 2003. ADs play a crucial role in ensuring the continuing airworthiness of aircraft types and aeronautical products, as outlined in Annex 8 to the Convention on International Civil Aviation. The State of Design, which is responsible for the aircraft type, must provide necessary information to ensure its airworthiness, and the State of Registry must then implement these directives for individual aircraft. CASA, acting on behalf of Australia, evaluates ADs issued by other countries and may issue corresponding Australian ADs to comply with international obligations.
The obligations imposed by the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 are primarily centred on the maintenance of aircraft airworthiness. The State of Design must ensure that all necessary information is provided to the State of Registry, which must then implement these requirements to maintain the airworthiness of aircraft on its register. CASA, as the national airworthiness authority, must assess ADs issued by other States of Design and may issue Australian ADs as required. This process ensures that Australian aircraft meet international safety standards and comply with the Convention on International Civil Aviation. The ADs must be issued in accordance with the legislative framework and by the appropriate authority within CASA, as outlined in subsection 84A(2) of the Act.
Breach of the obligations set out in the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 can lead to significant legal consequences. Non-compliance with ADs can result in the grounding of affected aircraft, which can have severe operational and financial impacts on airlines and other operators. Additionally, failure to adhere to the continuing airworthiness requirements can result in civil or criminal penalties under the Civil Aviation Act 1988. These penalties can include fines and imprisonment, depending on the severity of the breach and the specific provisions of the Act. The maximum penalties are determined by the courts and can vary widely based on the circumstances of each case. Ensuring compliance with ADs is therefore crucial to avoid these potential legal repercussions.
