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 2009-0030 affecting Eurocopter AS350 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/ECUREUIL/131 Amendment 1, which will become effective on 26 February 2009. 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 Best Practice Regulation has determined that ADs do not require a Regulatory Impact Statement.
The AD has been made by the Manager, Airframes & Structures in the Airworthiness Engineering Group, on behalf of CASA, in accordance with subsection 84A (2) of the Act.
Overview
The Civil Aviation Act 1988, enacted by the Australian Parliament, establishes a regulatory framework for ensuring the safety and efficiency of civil aviation. One significant aspect of this Act is the ability to issue airworthiness directives (ADs) through the Civil Aviation Safety Regulations 1998. These ADs are legislative instruments designed to address safety concerns and ensure the continuing airworthiness of aircraft types registered in Australia. In line with international obligations under the Convention on International Civil Aviation, the Civil Aviation Safety Authority (CASA) is tasked with assessing and issuing ADs when necessary, particularly in response to directives issued by the State of Design, such as the European Aviation Safety Authority (EASA) in the case of Eurocopter AS350 model helicopters. This regulatory approach aims to harmonise safety standards and practices across different jurisdictions, ensuring that Australian aviation remains compliant with international safety norms.
Scope and Application
The Civil Aviation Act 1988, supplemented by the Civil Aviation Safety Regulations 1998, empowers the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for particular types of aircraft or aeronautical products to ensure the safety of air navigation. These ADs, which are legislative instruments, apply to aircraft registered in Australia and require compliance with safety standards established by the State of Design, such as the European Aviation Safety Authority (EASA) for specific types like the Eurocopter AS350 model helicopters. CASA, as Australia’s national airworthiness authority, must assess international ADs and issue corresponding Australian ADs if deemed necessary. This process is mandated by Australia’s obligations under the Convention on International Civil Aviation and does not require public consultation or a Regulatory Impact Statement. The ADs extend to mandating specific safety measures and are enforced within the jurisdictional reach of the Commonwealth.
Key Provisions
The main operative sections of the Civil Aviation Act 1988, in conjunction with the Civil Aviation Safety Regulations 1998, provide the framework for the issuance of airworthiness directives (ADs). Under section 98 of the Civil Aviation Act 1988, the Governor-General has the authority to create regulations that promote the safety of air navigation. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 enables the Civil Aviation Safety Authority (CASA) to issue ADs for specific types of aircraft or aeronautical products. This regulatory power is further clarified by subregulation 39.001(5), which stipulates that an AD is a disallowable instrument under section 46A of the Acts Interpretation Act 1901 and a legislative instrument under section 6 of the Legislative Instruments Act 2003. These provisions ensure that ADs are formal, enforceable directives aimed at maintaining or restoring the airworthiness of aircraft.
The obligations and requirements imposed by these regulations are multi-faceted. The State of Design, which is responsible for the overall airworthiness of an aircraft type, must provide necessary information to the State of Registry to ensure that the aircraft remains airworthy. This obligation is detailed in Annex 8 to the Convention on International Civil Aviation. The State of Registry, in turn, is responsible for the continuing airworthiness of individual aircraft and must implement measures to ensure compliance with airworthiness standards. When the State of Design issues an AD, CASA must evaluate the information provided and, if necessary, issue an Australian AD to mandate the requirements of the State of Design. This ensures that Australian-registered aircraft conform to international safety standards.
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 also outline the consequences for non-compliance with ADs. Although specific penalties for non-compliance with ADs are not detailed in the provided text, general aviation regulations typically impose strict penalties for violations. These may include fines, imprisonment, or both, depending on the severity of the non-compliance and the impact on aviation safety. The seriousness of airworthiness issues necessitates stringent enforcement to maintain high safety standards in the aviation industry.
CASA, as the national airworthiness authority, plays a crucial role in enforcing these regulations. By issuing Australian ADs in response to ADs from the State of Design, CASA ensures that Australian aviation standards align with international requirements. This alignment is critical for maintaining the safety and integrity of the global aviation system. The AD issued in response to EASA’s AD 2009-0030, for example, demonstrates the collaborative effort between international aviation authorities to address safety concerns promptly and effectively.
