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 European Aviation Safety Authority (EASA) has issued AD 2006-0136 affecting Airbus A318, A319, A320 and A321 model aircraft. EASA acts on behalf of France, the State of Design for these types. CASA has assessed this AD and has issued Australian AD/A320/190, Amendment 3, which will become effective on 15 March 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 comprehensive legal framework governing civil aviation in Australia, with a particular focus on ensuring the safety of air navigation. This Act empowers the Governor-General to make regulations necessary for the safety of air navigation, as seen in the Civil Aviation Safety Regulations 1998. Under these regulations, the Civil Aviation Safety Authority (CASA) is authorised to issue airworthiness directives (ADs) for specific kinds of aircraft or aeronautical products, thereby facilitating the implementation of safety measures in response to identified risks. The ADs are legislative instruments subject to disallowance and are essential for maintaining the continuing airworthiness of aircraft types, aligning with international standards set by the International Civil Aviation Organization (ICAO). CASA’s role as the national airworthiness authority involves assessing ADs issued by the State of Design and, when necessary, issuing corresponding Australian ADs to ensure compliance with safety standards on the Australian Register.
Scope and Application
The Civil Aviation Act 1988, through its regulation 39.001 of the Civil Aviation Safety Regulations 1998, authorises the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products, thereby establishing its scope and application. This legislative framework applies to all entities and persons involved in the operation, maintenance, and certification of aircraft within Australia, ensuring compliance with safety standards and international conventions. The jurisdictional reach of the Act is national, with CASA as the regulatory body ensuring that the continuing airworthiness of aircraft registered in Australia is maintained. This legislative instrument extends its application through subordinate instruments such as ADs, which are disallowable and thus subject to parliamentary scrutiny. Importantly, this AD was issued in response to an AD from the European Aviation Safety Authority for the Airbus A318, A319, A320, and A321 models, reflecting Australia’s obligations under the Convention on International Civil Aviation. Notably, because this AD responds to international obligations and pre-existing directives from the State of Design, it does not require public consultation or a Regulatory Impact Statement.
Key Provisions
The Civil Aviation Act 1988, specifically section 98, empowers the Governor-General to create regulations to ensure the safety of air navigation. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for certain types of aircraft or aeronautical products. These directives are formal, legally binding documents that establish safety standards and compliance requirements for aircraft maintenance, repair, and operation. Subregulation 39.001(5) clarifies that ADs are considered disallowable instruments under section 46A of the Acts Interpretation Act 1901 and are legislative instruments as per section 6 of the Legislative Instruments Act 2003.
Airworthiness directives are critical for ensuring the continuing safety and airworthiness of aircraft. The State of Design, as per Annex 8 of the Convention on International Civil Aviation, holds the primary responsibility for the continuing airworthiness of aircraft types and must provide necessary information to the States of Registry. The State of Registry, in turn, must establish or adopt requirements to maintain the airworthiness of aircraft registered within its jurisdiction. When a State of Design issues an AD, CASA, as Australia's national airworthiness authority, must evaluate this information and, if necessary, issue an Australian AD to enforce the requirements of the State of Design. For instance, the European Aviation Safety Authority (EASA) issued AD 2006-0136 for Airbus A318, A319, A320, and A321 model aircraft, and CASA subsequently issued Australian AD/A320/190, Amendment 3, effective from 15 March 2007.
The obligations imposed by these regulations are significant. The State of Design must communicate any safety-related issues or required maintenance actions to the States of Registry. CASA, as the national authority, must assess these communications and decide whether to issue a corresponding AD for aircraft registered in Australia. Compliance with these ADs is mandatory for aircraft operators, maintenance providers, and other relevant parties. Failure to adhere to the ADs can result in serious safety risks and legal consequences.
Failure to comply with airworthiness directives can lead to severe penalties. Under the Civil Aviation Act 1988, non-compliance can result in civil penalties, including fines and other sanctions. The maximum penalties can vary depending on the severity of the breach and the specific provisions of the ADs. In addition, non-compliance with ADs can also have criminal consequences, leading to prosecution and potential imprisonment. CASA is tasked with enforcing these regulations and can take legal action against individuals or entities that fail to comply with the mandated safety standards.
