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 2008-0033 affecting Dowty Rotol propellers. EASA acts on behalf of the United Kingdom; the State of Design for these propellers. CASA has assessed this AD and has issued Australian AD/PR/39, which will become effective on 31 July 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, Systems and New Technologies 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 provide a comprehensive legal framework for civil aviation in Australia, ensuring the safety and efficiency of air navigation and operations. The Act empowers the Governor-General to make regulations, such as the Civil Aviation Safety Regulations 1998, which include provisions for issuing airworthiness directives (ADs). ADs are legislative instruments designed to maintain the continuing airworthiness of aircraft and aeronautical products, reflecting Australia’s commitments under the Convention on International Civil Aviation. The Civil Aviation Safety Authority (CASA) issues these directives, which mandate specific actions to address identified safety issues. For instance, in response to AD 2008-0033 issued by the European Aviation Safety Authority concerning Dowty Rotol propellers, CASA issued Australian AD/PR/39, effective from 31 July 2008. Given that this directive aligns with international obligations and follows an AD from the relevant State of Design, it did not require public consultation or a Regulatory Impact Statement. Instead, it was prepared by the Manager, Systems and New Technologies in the Airworthiness Engineering Branch of CASA, in accordance with the legislative framework established by the Act.
Scope and Application
The Civil Aviation Safety Regulations 1998, specifically regulation 39.001, empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for particular types of aircraft or aeronautical products, thereby ensuring the safety of air navigation as per section 98 of the Civil Aviation Act 1988. These ADs, which are legislative instruments under the Legislative Instruments Act 2003, are essential for maintaining the continuing airworthiness of aircraft as mandated by Annex 8 to the Convention on International Civil Aviation. The State of Registry, which is responsible for the individual aircraft, must comply with these ADs, ensuring they align with international standards and practices. For instance, following the issuance of AD 2008-0033 by the European Aviation Safety Authority (EASA) concerning Dowty Rotol propellers, CASA assessed the directive and issued Australian AD/PR/39, effective from 31 July 2008. The process for issuing these directives is driven by international obligations and the need to respond to directives from the relevant State of Design, and therefore does not require public consultation or a Regulatory Impact Statement. The ADs are made by the Manager, Systems and New Technologies in the Airworthiness Engineering Branch, on behalf of CASA, in accordance with the Act.
Key Provisions
The Civil Aviation Act 1988, as supplemented by the Civil Aviation Safety Regulations 1998, allows for the issuance of airworthiness directives (ADs) under regulation 39.001. These directives are legislative instruments that pertain to specific types of aircraft or aeronautical products. This process is overseen by the Civil Aviation Safety Authority (CASA), which is empowered to issue such directives to ensure compliance with safety standards (sections 98 and 39.001(5)). When CASA issues an AD, it is doing so in response to international obligations under Annex 8 of the Convention on International Civil Aviation, which mandates that the State of Design provides necessary information for the continuing airworthiness of an aircraft type, and that the State of Registry ensures the ongoing airworthiness of individual aircraft.
The obligations imposed on parties governed by this Act include a responsibility on the State of Design to provide necessary information to ensure the continuing airworthiness of an aircraft type. The State of Registry, in this case CASA, must assess any international ADs and, if appropriate, issue corresponding Australian ADs to mandate the safety requirements of the State of Design. This ensures that aircraft registered in Australia meet international safety standards. CASA must also ensure that any ADs issued are consistent with the obligations under the Convention on International Civil Aviation and that they are assessed and implemented in a timely manner.
Failure to comply with an AD can result in significant legal consequences. The Act does not explicitly state the penalties for non-compliance with an AD; however, non-compliance with civil aviation regulations generally can lead to serious civil and criminal penalties. Civil penalties may include fines, and criminal penalties may include imprisonment, depending on the severity of the non-compliance and the discretion of the court. The exact penalties would be determined by the specific circumstances of the case and the relevant jurisdictional laws. It is essential for operators and owners of aircraft to adhere strictly to ADs to avoid these potential penalties and to ensure the safety of air navigation.
