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 Brazilian ANAC has issued AD 2002-09-01R1 affecting Embraer 145 model aircraft. Brazil is the State of Design for this type. CASA has assessed this AD and has issued Australian AD/EMB-145/10, 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, 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 was enacted to provide a comprehensive legislative framework for civil aviation in Australia, ensuring the safety, efficiency, and orderly development of air navigation and air transport. This Act empowers the Governor-General to create regulations that serve the interests of air navigation safety, as exemplified by the Civil Aviation Safety Regulations 1998. Under these regulations, the Civil Aviation Safety Authority (CASA) has the authority to issue airworthiness directives (ADs) for certain aircraft or aeronautical products. These ADs are legislative instruments, subject to disallowance and review under the Acts Interpretation Act 1901 and the Legislative Instruments Act 2003 respectively. The overarching aim of these provisions is to align Australian aviation practices with international standards and to ensure the continuing airworthiness of aircraft as mandated by the Convention on International Civil Aviation.
In specific instances, such as the issuance of AD/EMB-145/10 for the Embraer 145 model aircraft, CASA exercises its regulatory function to mandate compliance with airworthiness directives issued by the aircraft's State of Design, in this case, Brazil. Given that these directives arise from international obligations and are in direct response to foreign ADs, they do not require public consultation or a Regulatory Impact Statement. Instead, CASA issues these directives under the authority conferred by the Civil Aviation Act 1988, reflecting its role as Australia's national airworthiness authority.
Scope and Application
The Civil Aviation Act 1988, supplemented by the Civil Aviation Safety Regulations 1998, outlines the framework within which airworthiness directives (ADs) are issued in Australia to ensure the safety of air navigation. Specifically, regulation 39.001 empowers the Civil Aviation Safety Authority (CASA) to issue ADs for certain types of aircraft or aeronautical products. These ADs are legislative instruments that must comply with the Acts Interpretation Act 1901 and the Legislative Instruments Act 2003. The authority to issue such directives is grounded in the broader obligations of the State of Design under Annex 8 to the Convention on International Civil Aviation, which places responsibility for continuing airworthiness on the State of Design and requires them to provide necessary information to States of Registry. In Australia, CASA, as the national airworthiness authority, must assess this information and, if necessary, issue corresponding Australian ADs to enforce the requirements set by the State of Design. The scope of the ADs extends to all aircraft of the specified type registered in Australia, ensuring compliance with both international standards and domestic regulatory requirements. This process is conducted without public consultation as it pertains to international obligations and is not subject to a Regulatory Impact Statement, reflecting its technical and safety-focused nature.
Key Provisions
The main operative sections of the Civil Aviation Act 1988, particularly section 98, empower the Governor-General to make regulations that serve the purposes of the Act and ensure the safety of air navigation. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 specifically allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific kinds of aircraft or aeronautical products. This regulatory framework is designed to maintain the safety and airworthiness of aircraft operating in Australian airspace. Subregulation 39.001(5) further clarifies that an AD is a disallowable instrument under the Acts Interpretation Act 1901, and as such, it is also a legislative instrument under the Legislative Instruments Act 2003.
The obligations imposed by these provisions on the parties and entities governed by the Act are substantial. CASA, as Australia’s national airworthiness authority, must assess any airworthiness directives issued by the State of Design for aircraft types registered in Australia. When the State of Design, in this case Brazil for the Embraer 145 model aircraft, issues an AD, CASA must evaluate the information and, if deemed necessary, issue a corresponding Australian AD to enforce the requirements. This ensures that Australian-registered aircraft meet international safety standards. The State of Registry, which in this context is Australia, has the responsibility to ensure the continuing airworthiness of its registered aircraft, aligning with the requirements outlined in Annex 8 of the Convention on International Civil Aviation.
Failure to comply with an AD can lead to significant consequences. The Civil Aviation Safety Regulations 1998 outline that non-compliance with an AD can result in serious safety risks, potentially leading to offences under the Civil Aviation Act 1988. The specific penalties for breaching these regulations can include fines and imprisonment, depending on the severity of the breach. The maximum penalties are not specified in the provided text but are generally determined by the seriousness of the violation and the risk posed to public safety. Civil and criminal liability may also arise for operators who fail to adhere to the mandated airworthiness directives, highlighting the importance of compliance for maintaining aviation safety standards.
