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 EASA has issued AD 2008-0113 affecting Eurocopter Deutschland GmbH MBB-BK-117 C-2 helicopters. Germany is the State of Design for these helicopters. CASA has assessed this AD and has issued Australian AD/GBK 117/20, 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 Regulatory Review has determined that ADs do not require a Regulatory Impact Statement.
The AD has been made by the Manager, New Technologies and Systems, 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 Australian Parliament, was introduced to provide a framework for ensuring the safety of civil aviation in Australia. This Act enables the Governor-General to make regulations that support the Act's objectives, particularly focusing on the safety of air navigation. Under the Act, the Civil Aviation Safety Regulations 1998 were established, which include provisions for the issuance of airworthiness directives (ADs) by the Civil Aviation Safety Authority (CASA). ADs are legislative instruments that are issued in accordance with international standards set by the International Civil Aviation Organization (ICAO) and are designed to maintain the continuing airworthiness of aircraft. The ADs are crucial for ensuring compliance with international obligations and maintaining safety standards in the Australian civil aviation sector. The process of issuing ADs, such as the recent Australian AD/GBK 117/20 concerning Eurocopter Deutschland GmbH MBB-BK-117 C-2 helicopters, reflects Australia’s commitment to adhering to ICAO guidelines and its responsibility as a State of Registry to enforce airworthiness directives issued by the State of Design.
Scope and Application
The Civil Aviation Act 1988, supplemented by the Civil Aviation Safety Regulations 1998, provides the framework for the issuance of airworthiness directives (ADs) in Australia, with the primary objective of ensuring the safety of air navigation. Under this legislative structure, the Civil Aviation Safety Authority (CASA) is empowered to issue ADs for specific types of aircraft or aeronautical products as stipulated in regulation 39.001 of the Civil Aviation Safety Regulations 1998. These ADs serve as legislative instruments and are subject to disallowance under the Acts Interpretation Act 1901. In alignment with international standards under Annex 8 of the Convention on International Civil Aviation, the State of Design of an aircraft retains overall responsibility for the continuing airworthiness of an aircraft type, while the State of Registry is tasked with ensuring the continuing airworthiness of individual aircraft within its registry. Consequently, when a State of Design issues an AD, such as AD 2008-0113 by the European Aviation Safety Agency affecting Eurocopter Deutschland GmbH MBB-BK-117 C-2 helicopters, CASA must assess this information and, if deemed necessary, issue an Australian AD to enforce the requirements set forth by the State of Design. This process ensures that Australian aircraft meet the necessary safety standards as mandated by international conventions.
Key Provisions
The Civil Aviation Safety Regulations 1998, under regulation 39.001, empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific kinds of aircraft or aeronautical products. These directives, as outlined in subregulation 39.001(5), are considered disallowable instruments under section 46A of the Acts Interpretation Act 1901 and, as such, are legislative instruments under section 6 of the Legislative Instruments Act 2003. The ADs are fundamental for ensuring the continuing airworthiness of aircraft types, a responsibility that primarily lies with the State of Design but is also overseen by the State of Registry, as stipulated in Annex 8 to the Convention on International Civil Aviation. In the case of Australia, CASA must assess any ADs issued by the State of Design and, if necessary, issue corresponding Australian ADs to enforce the requirements.
Obligations under the Civil Aviation Safety Regulations 1998 place specific duties on CASA and other entities. For instance, CASA must evaluate ADs issued by the State of Design to ensure they meet the safety standards required under the Civil Aviation Act 1988. If an AD is deemed necessary, CASA must then issue an Australian AD, which becomes legally binding and enforceable. The State of Registry also has a role in implementing these directives, ensuring that all aircraft on the Australian Register comply with the continuing airworthiness requirements. These obligations ensure that the safety and airworthiness standards are uniformly maintained across all aircraft operating in Australia.
Violations of the airworthiness directives can result in significant consequences. Under the Civil Aviation Act 1988, non-compliance with ADs can lead to enforcement actions. Specifically, CASA can take measures to ensure compliance, which may include fines or other penalties. The severity of the penalties can vary, but in some cases, significant fines can be imposed, particularly if the non-compliance results in safety hazards or incidents. Additionally, continued non-compliance could lead to further legal actions, including potential prosecution under the Act. It is crucial for all parties involved, including aircraft operators and owners, to adhere strictly to the requirements set forth in the ADs to avoid these consequences.
