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 United States FAA has issued AD 2007-11-17 affecting Cessna 500 and 501 model aircraft. The United States is the State of Design for these types. CASA has assessed this AD and has issued Australian AD/CESSNA 500/30, which will become effective on 2 August 2007.
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 Acting Manager, New Technologies and Systems, in the Manufacturing, Certification and New Technologies Office, 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 the regulation of civil aviation in Australia, aiming to ensure the safety and efficiency of air navigation. The Act empowers the Governor-General to make regulations for the safety of air navigation, and under this authority, the Civil Aviation Safety Regulations 1998 were created. These regulations permit the issuance of airworthiness directives (ADs) by the Civil Aviation Safety Authority (CASA) to maintain the continuing airworthiness of aircraft and aeronautical products. The ADs are legislative instruments, which need to comply with the Legislative Instruments Act 2003. Australia’s obligations under the Convention on International Civil Aviation, particularly those concerning the responsibilities of the State of Design and the State of Registry, guide the issuance and implementation of these directives. The ADs serve as critical tools for harmonising international airworthiness standards, and CASA issues Australian ADs in response to directives from the relevant State of Design, such as the United States in the case of Cessna 500 and 501 models. This approach ensures that Australian aviation remains compliant with international safety standards.
Scope and Application
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 provide the framework for the issuance of airworthiness directives (ADs) by the Civil Aviation Safety Authority (CASA) to ensure the safety of air navigation. Specifically, regulation 39.001 of the Civil Aviation Safety Regulations 1998 empowers CASA to issue ADs for specific types of aircraft or aeronautical products, and these directives are considered legislative instruments under the Acts Interpretation Act 1901 and the Legislative Instruments Act 2003. The geographic and jurisdictional reach of these regulations is national, applying to all aircraft registered in Australia. The ADs are issued in accordance with Australia's obligations under the Convention on International Civil Aviation, particularly Annex 8, which mandates the State of Design to provide necessary information for the continuing airworthiness of aircraft types. CASA, as Australia's national airworthiness authority, assesses this information and, if necessary, issues corresponding Australian ADs to enforce the requirements of the State of Design. For instance, in response to a United States Federal Aviation Administration AD affecting Cessna 500 and 501 model aircraft, CASA issued AD/CESSNA 500/30, which became effective on 2 August 2007. Notably, these ADs do not require public consultation or a Regulatory Impact Statement, as they are directly linked to international obligations and the assessment of directives from the aircraft's State of Design.
Key Provisions
The Civil Aviation Act 1988 (section 98) grants the Governor-General the authority to enact regulations intended to safeguard air navigation, while regulation 39.001 of the Civil Aviation Safety Regulations 1998 enables CASA to issue airworthiness directives (ADs) for specific aircraft types or aeronautical products. Subregulation 39.001(5) of the same regulations further clarifies that ADs are considered disallowable instruments under section 46A of the Acts Interpretation Act 1901, and are legislative instruments as per section 6 of the Legislative Instruments Act 2003. In accordance with Annex 8 to the Convention on International Civil Aviation, the State of Design is tasked with maintaining the airworthiness of an aircraft type, and must provide necessary information to ensure the continuing airworthiness of a type to appropriate States of Registry. ADs are the most common form of continuing airworthiness information issued by most ICAO Contracting States.
Under the Civil Aviation Safety Regulations 1998, the State of Registry of an individual aircraft bears the responsibility for its ongoing airworthiness, and 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 the information and, if appropriate, issue an Australian AD to mandate the requirements of the State of Design. In the case of the United States FAA issuing AD 2007-11-17 affecting Cessna 500 and 501 model aircraft, CASA has assessed the AD and issued Australian AD/CESSNA 500/30, effective from 2 August 2007.
Given Australia's obligations under the Convention on International Civil Aviation and in response to an AD issued by the relevant State of Design, no consultation with the Australian public has taken place regarding this AD. The Office of Regulatory Review has determined that ADs do not require a Regulatory Impact Statement. This AD was made by the Acting Manager, New Technologies and Systems, in the Manufacturing, Certification and New Technologies Office, on behalf of CASA, in accordance with subsection 84A(2) of the Civil Aviation Act 1988.
The Civil Aviation Safety Regulations 1998 impose obligations on the parties and entities it governs, including the State of Registry, which must develop or adopt requirements to ensure the continuing airworthiness of aircraft. CASA, as Australia’s national airworthiness authority, must assess ADs issued by the State of Design and issue Australian ADs as necessary. Additionally, the State of Design must provide any necessary information to ensure the continuing airworthiness of a type to appropriate States of Registry. Any breach of these obligations may lead to potential safety risks and could result in civil or criminal consequences.
Section 164 of the Civil Aviation Act 1988 stipulates that a person who contravenes the Civil Aviation Regulations 1998 may be liable to a civil penalty of up to 500 penalty units (currently AUD 55,000) for individuals and 2,750 penalty units (currently AUD 300,000) for bodies corporate. In addition to civil penalties, there could also be criminal consequences, including fines and imprisonment, depending on the severity of the breach. The specific maximum penalties for criminal offences under the Civil Aviation Act 1988 can vary, but they may include substantial fines and/or imprisonment terms, depending on the nature and severity of the offence.
