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 2008-15-06 affecting Cessna 175 model aircraft. The USA is the State of Design for this type. CASA has assessed this AD and has issued Australian AD/CESSNA 170/84, which will become effective on 25 September 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, enacted by the Parliament of Australia, was introduced to ensure the safety of air navigation and to establish the regulatory framework governing civil aviation in Australia. Under this Act, the Civil Aviation Safety Regulations 1998 were established to further detail the operational standards and regulatory measures necessary for maintaining air safety. The Civil Aviation Safety Regulations 1998 empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products to ensure continuing airworthiness. These directives are considered legislative instruments and are subject to disallowance under the Acts Interpretation Act 1901. The objective of these regulations is to align with international standards, particularly those outlined in Annex 8 to the Convention on International Civil Aviation, ensuring that both the State of Design and the State of Registry of aircraft maintain oversight and compliance with necessary safety measures. The ADs issued by CASA reflect Australia's commitment to international safety standards and are issued in response to directives from the relevant State of Design without the need for public consultation.
Scope and Application
The Civil Aviation Act 1988, supplemented by the Civil Aviation Safety Regulations 1998, governs the issuance of airworthiness directives (ADs) in Australia, which are regulatory instruments designed to ensure the safety and airworthiness of aircraft. Under this framework, the Civil Aviation Safety Authority (CASA), acting on behalf of the Commonwealth, can issue ADs for specific types of aircraft or aeronautical products to comply with national and international safety standards. These directives apply to all aircraft registered in Australia, as well as to any entities or persons involved in the operation or maintenance of such aircraft. The ADs are based on the obligations set out in Annex 8 to the Convention on International Civil Aviation and mandate compliance with continuing airworthiness requirements. While ADs are legislative instruments and must be assessed and approved by CASA, the process does not typically involve public consultation or require a Regulatory Impact Statement, given their technical nature and the international framework underpinning their issuance.
Key Provisions
The Civil Aviation Act 1988, in conjunction with the Civil Aviation Safety Regulations 1998, establishes the framework through which the Civil Aviation Safety Authority (CASA) can issue airworthiness directives (ADs). According to section 98 of the Civil Aviation Act 1988, the Governor-General is empowered to enact regulations that serve the interests of air navigation safety. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 authorises CASA to issue ADs for specified types of aircraft or aeronautical products. This regulatory mechanism is integral to maintaining the safety and airworthiness of aircraft within Australia, as stipulated by Annex 8 of the Convention on International Civil Aviation, which designates the State of Design as the entity with overarching responsibility for the continuing airworthiness of an aircraft type.
CASA, as Australia’s national airworthiness authority, is tasked with assessing information provided by the State of Design and issuing corresponding Australian ADs when necessary. This process ensures that the requirements for airworthiness are uniformly enforced across aircraft types registered in Australia. For instance, following the issuance of AD 2008-15-06 by the US Federal Aviation Administration (FAA) for Cessna 175 model aircraft, CASA assessed this directive and issued Australian AD/CESSNA 170/84, which was set to become effective on 25 September 2008. Given the international obligations under the Convention on International Civil Aviation and the direct response to an AD from the relevant State of Design, no public consultation was required for this AD, as confirmed by the Office of Best Practice Regulation.
The obligations imposed on the parties governed by this Act are significant. CASA must meticulously evaluate and, if necessary, implement Australian ADs in response to directives from the State of Design. The State of Registry is also responsible for ensuring the continuing airworthiness of individual aircraft, developing or adopting requisite requirements to meet this obligation. This includes adhering to the ADs issued by CASA, which are designed to maintain safety standards consistent with international conventions. Additionally, the legislative framework ensures that ADs, such as Australian AD/CESSNA 170/84, are issued in accordance with the Act, as evidenced by the authority exercised by the Manager, Airframes in the Airworthiness Engineering Branch, on behalf of CASA, pursuant to subsection 84A(2) of the Act.
The breach of any requirement or mandate set forth by the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 can lead to various civil and criminal consequences. Offences under the Act may result in penalties that include fines and imprisonment. For instance, non-compliance with ADs can be prosecuted under the Act, leading to significant penalties. The specific maximum penalties depend on the severity of the breach and are outlined within the Act and related regulations. The rigorous enforcement of these provisions underscores the critical importance of maintaining air navigation safety and the continuing airworthiness of aircraft.
