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 Civil Aviation Safety Authority or its predecessors issued AD/AA-5/12 affecting Gulfstream AA-5 model aircraft. CASA has assessed this AD and as a result has cancelled AD/AA-5/12. The cancellation will become effective on 4 June 2009. No replacement AD is required, as the unsafe condition no longer exists.
As this AD has been cancelled because of Australia’s obligations under the Convention on International Civil Aviation, no consultation with the Australian public has taken place on this AD cancellation. 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 and 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 was enacted to regulate civil aviation within Australia, ensuring safety and efficiency in the aviation sector. The Act empowers the Governor-General to make regulations that serve the interests of air navigation safety, such as the issuance of airworthiness directives. The Civil Aviation Safety Regulations 1998 provide the framework under which the Civil Aviation Safety Authority (CASA) can issue these directives, which are integral for maintaining the continuing airworthiness of aircraft. The ADs are legislative instruments, falling under the purview of the Legislative Instruments Act 2003. This legislative process is aligned with international standards, particularly under Annex 8 to the Convention on International Civil Aviation, which mandates the State of Design to provide necessary information for airworthiness. Consequently, CASA, as Australia’s national airworthiness authority, is responsible for assessing and, if necessary, issuing Australian ADs to enforce the requirements of the State of Design. The recent cancellation of AD/AA-5/12 for Gulfstream AA-5 model aircraft exemplifies this regulatory mechanism, reflecting Australia’s commitment to international aviation safety standards.
Scope and Application
The Civil Aviation Act 1988 applies to entities and individuals involved in civil aviation within Australia, including aircraft manufacturers, operators, and maintenance providers, ensuring that they adhere to safety standards. Under this Act, the Civil Aviation Safety Regulations 1998 permit the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products, thereby ensuring these meet continuing airworthiness requirements. These ADs are legislative instruments and serve as a mechanism to address any unsafe conditions that might arise with particular aircraft types registered in Australia. The ADs issued by CASA are aligned with the requirements set forth by the Convention on International Civil Aviation, where the State of Design has the responsibility for the ongoing airworthiness of aircraft types. As Australia’s national airworthiness authority, CASA must assess any ADs issued by other countries and, if necessary, issue corresponding ADs for aircraft registered in Australia to ensure compliance with international safety standards. The authority to issue ADs is exercised under specific regulations and does not require consultation with the public or a Regulatory Impact Statement, reflecting the technical nature of the instrument.
Key Provisions
The Civil Aviation Act 1988, through section 98, authorises the Governor-General to make regulations that ensure the safety of air navigation. These regulations include the Civil Aviation Safety Regulations 1998, which under regulation 39.001 allow the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific kinds of aircraft or aeronautical products. Subregulation 39.001(5) further clarifies that an AD is a disallowable instrument under section 46A of the Acts Interpretation Act 1901 and therefore constitutes a legislative instrument under section 6 of the Legislative Instruments Act 2003.
The obligations imposed by these provisions on CASA and the aircraft industry include ensuring the continuing airworthiness of aircraft registered in Australia. This is achieved through the issuance and assessment of ADs by CASA. When a State of Design issues an AD for a type of aircraft registered in Australia, CASA must evaluate the information and, if necessary, issue a corresponding Australian AD to enforce the requirements set by the State of Design. This process is crucial for maintaining the safety standards of aircraft operating in Australia, aligning with international obligations under Annex 8 to the Convention on International Civil Aviation.
Under these regulations, CASA must also ensure that any AD issued is based on comprehensive assessments and compliance with international safety standards. For instance, the cancellation of AD/AA-5/12 for Gulfstream AA-5 model aircraft on 4 June 2009 was a result of CASA’s assessment that the unsafe condition no longer existed, thereby fulfilling Australia’s obligations under the Convention on International Civil Aviation. This cancellation was made without public consultation, as the Office of Best Practice Regulation determined that ADs do not require a Regulatory Impact Statement.
Any breach of the requirements set forth in the Civil Aviation Safety Regulations 1998 can lead to both civil and criminal consequences. Civil penalties may include fines, while criminal penalties can result in imprisonment, reflecting the seriousness of ensuring air safety. The maximum penalties for breaches of these regulations are determined by the severity of the violation and the impact on public safety, underscoring the critical nature of compliance with airworthiness directives.
