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 2006-0345 affecting MT Propellers. The EASA is the State of Design for these propellers. CASA has assessed this AD and has issued Australian AD/PFP/19, which will become effective on 12 April 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 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, enacted by the Commonwealth Parliament, serves to establish a regulatory framework that ensures the safety of air navigation within Australia. The Act empowers the Governor-General to create regulations aimed at enhancing air safety, with one of its significant provisions being the ability to issue airworthiness directives. These directives, which fall under the Civil Aviation Safety Regulations 1998, are crucial for maintaining the ongoing airworthiness of aircraft and aeronautical products. This legislative mechanism is integral to Australia's commitment to international standards as set forth by the Convention on International Civil Aviation, particularly in adhering to the obligations of the State of Design and the State of Registry. In this context, the Civil Aviation Safety Authority (CASA), as Australia's national airworthiness authority, is mandated to assess and, if necessary, issue Australian airworthiness directives in response to those issued by other contracting states, such as the European Aviation Safety Agency (EASA). The issuance of such directives is a formal process overseen by CASA, reflecting Australia's dedication to maintaining high safety standards in civil aviation.
Scope and Application
The Civil Aviation Safety Regulations 1998, under the Civil Aviation Act 1988, empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specified kinds of aircraft or aeronautical products. This regulatory framework ensures the safety of air navigation and aligns with the obligations under Annex 8 to the Convention on International Civil Aviation. The State of Design has the overarching responsibility for the continuing airworthiness of an aircraft type and must provide necessary information to States of Registry. CASA, as Australia's national airworthiness authority, is mandated to assess this information and, if deemed appropriate, issue an Australian AD to enforce the requirements of the State of Design. For instance, the European Union Aviation Safety Agency (EASA) issued AD 2006-0345 concerning MT Propellers, prompting CASA to issue Australian AD/PFP/19, effective from 12 April 2007. This process does not require public consultation as it is driven by international obligations and the assessment of relevant ADs. Additionally, such ADs are not subject to a Regulatory Impact Statement, and they are made under the authority of the Manager, New Technologies and Systems, within CASA's Manufacturing, Certification and New Technologies Office, in compliance with the Act.
Key Provisions
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 lay out the framework for ensuring the safety and airworthiness of aircraft operating in Australian airspace. Section 98 of the Civil Aviation Act 1988 empowers the Governor-General to create regulations that are crucial for the safety of air navigation. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 grants the Civil Aviation Safety Authority (CASA) the authority to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. Importantly, subregulation 39.001(5) of the Civil Aviation Safety Regulations 1998 clarifies that an AD is a disallowable instrument under section 46A of the Acts Interpretation Act 1901, making it a legislative instrument in its own right.
The obligations imposed by the Act and its regulations on the parties involved are significant. Under Annex 8 to the Convention on International Civil Aviation, the State of Design holds the overarching responsibility for the continuing airworthiness of an aircraft type and must provide necessary information to ensure this airworthiness to the appropriate States of Registry. In Australia, CASA, as the national airworthiness authority, must assess any ADs issued by the State of Design and, if appropriate, issue an Australian AD to enforce the requirements of the State of Design. The State of Registry is also tasked with ensuring the continuing airworthiness of individual aircraft by developing or adopting the necessary requirements.
Failure to comply with the requirements set forth in an AD can lead to severe consequences. The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 outline specific offences and penalties for breaches. Civil penalties can include fines, while criminal penalties may involve imprisonment, reflecting the seriousness with which non-compliance is viewed. The maximum penalties are determined by the severity of the breach and the impact on aviation safety. In the context of ADs, the enforcement of these provisions is crucial to maintaining the high safety standards required in the aviation industry.
