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 2006-0180-E affecting Eurocopter EC 225 LP model helicopters. EASA acts on behalf of France, the State of Design for this type. CASA has assessed this AD and has issued Australian AD/EC 225/5, which will become effective on 23 October 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 establish a framework for the regulation of civil aviation in Australia, ensuring the safety and efficiency of air navigation. Under this Act, the Governor-General has the authority to create regulations that safeguard air navigation, as outlined in section 98. One such regulation, 39.001 of the Civil Aviation Safety Regulations 1998, empowers the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specified types of aircraft or aeronautical products. These ADs, which are legislative instruments, are essential for maintaining the continuing airworthiness of aircraft as mandated by Annex 8 to the Convention on International Civil Aviation. CASA, as Australia’s national airworthiness authority, assesses ADs issued by the State of Design and, where necessary, issues corresponding Australian ADs to enforce the required safety measures, thus fulfilling Australia’s international obligations and ensuring the safety of air navigation.
Scope and Application
The Civil Aviation Act 1988, supplemented by the Civil Aviation Safety Regulations 1998, provides the legislative framework for ensuring the safety of air navigation in Australia, with specific application to the issuance of airworthiness directives (ADs) concerning aircraft and aeronautical products. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 allows the Civil Aviation Safety Authority (CASA) to issue ADs for certain types of aircraft or aeronautical products, thereby mandating safety requirements. The ADs are considered legislative instruments under the Legislative Instruments Act 2003 and must be aligned with international standards, particularly those set forth in Annex 8 to the Convention on International Civil Aviation. These ADs apply to aircraft registered in Australia, and CASA, as the national airworthiness authority, is tasked with assessing ADs issued by the State of Design and, if necessary, issuing corresponding Australian ADs to ensure compliance with international safety standards. The issuance of these ADs is governed by Australia's obligations under international conventions, and as such, they do not typically require public consultation or a Regulatory Impact Statement.
Key Provisions
The Civil Aviation Act 1988, through section 98, empowers the Governor-General to establish regulations aimed at ensuring the safety of air navigation. This regulatory authority is further delineated in regulation 39.001 of the Civil Aviation Safety Regulations 1998, which allows 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 defined under subregulation 39.001(5) of the Civil Aviation Safety Regulations 1998, which aligns with the requirements of the Acts Interpretation Act 1901 and the Legislative Instruments Act 2003.
Under the Convention on International Civil Aviation, particularly Annex 8, the State of Design holds primary responsibility for the continuing airworthiness of an aircraft type, including the provision of necessary information to States of Registry. The State of Registry, in turn, must develop or adopt requirements to ensure the continuing airworthiness of individual aircraft. When a State of Design issues an AD, CASA, as Australia’s national airworthiness authority, must evaluate this information and, if deemed necessary, issue an Australian AD to enforce the requirements set by the State of Design.
The European Aviation Safety Authority (EASA) has issued an AD, 2006-0180-E, affecting the Eurocopter EC 225 LP model helicopters, on behalf of France as the State of Design. CASA has reviewed this AD and issued Australian AD/EC 225/5, which is set to take effect on 23 October 2008. Given that this AD is issued due to Australia’s obligations under the Convention on International Civil Aviation and in response to an AD raised by the relevant State of Design, no public consultation has been conducted. Furthermore, the Office of Best Practice Regulation has concluded that ADs do not necessitate a Regulatory Impact Statement.
Breaches of ADs can have significant legal implications. Under section 303 of the Civil Aviation Act 1988, an operator who fails to comply with an AD can be subject to civil penalties, including fines of up to $252,000 for a corporation and $50,400 for an individual, as well as potential criminal penalties for serious non-compliance. Additionally, CASA may take enforcement actions, such as grounding non-compliant aircraft, which can result in operational disruptions and financial losses for the operator. Thus, adherence to ADs is critical to maintaining the safety and airworthiness of aircraft operating within Australia.
