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 Japanese CAB has issued AD TCD-7030-2006 affecting Mitsubishi MU-2B model aircraft. Japan is the State of Design for this type. CASA has assessed this AD and has issued Australian AD/MU-2/71, which will become effective on 15 March 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, Airframes 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 regulate civil aviation in Australia, establishing the framework for ensuring the safety and efficiency of air navigation within the country. This Act empowers the Governor-General to make regulations to enhance air navigation safety, as outlined in section 98. Specifically, under regulation 39.001 of the Civil Aviation Safety Regulations 1998, the Civil Aviation Safety Authority (CASA) is authorised to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products to ensure compliance with safety standards. The Civil Aviation Act 1988 addresses the need for a comprehensive legislative framework to govern civil aviation safety and airworthiness in Australia, ensuring that domestic aviation operations meet both national and international safety standards.
The Civil Aviation Safety Regulations 1998, established under the authority of the Civil Aviation Act 1988, further detail the procedures and requirements for maintaining the airworthiness of aircraft. These regulations empower CASA to issue ADs, which are legislative instruments subject to disallowance under section 46A of the Acts Interpretation Act 1901. The objective of these regulations is to ensure that aircraft meet continuing airworthiness standards, in line with obligations under the Convention on International Civil Aviation and the responsibilities of the State of Design and State of Registry. The issuance of Australian AD/MU-2/71 by CASA in response to a Japanese AD for Mitsubishi MU-2B model aircraft exemplifies the application of these regulations to maintain air safety in accordance with international standards.
Scope and Application
The Civil Aviation Act 1988, through regulation 39.001 of the Civil Aviation Safety Regulations 1998, empowers the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific kinds of aircraft or aeronautical products, thereby ensuring the continuing safety of air navigation. This regulatory framework is designed to maintain the highest safety standards in accordance with Australia's obligations under the Convention on International Civil Aviation, particularly Annex 8 which mandates that the State of Design bears the responsibility for the continuing airworthiness of an aircraft type. In the case of the Mitsubishi MU-2B model aircraft, Japan, as the State of Design, issued AD TCD-7030-2006, prompting CASA to assess and subsequently issue Australian AD/MU-2/71, effective from 15 March 2007. The issuance of these directives is a legislative instrument, disallowable under section 46A of the Acts Interpretation Act 1901 and regulated under the Legislative Instruments Act 2003. Given that these directives arise from international obligations and specific design state actions, they are not subject to public consultation or a Regulatory Impact Statement. Instead, the ADs are crafted by CASA's Manager, Airframes within the Manufacturing, Certification and New Technologies Office, acting under the authority granted by the Civil Aviation Act 1988.
Key Provisions
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 together establish the framework for the regulation of airworthiness in Australia. Specifically, section 98 of the Civil Aviation Act 1988 empowers the Governor-General to make regulations for the safety of air navigation, while regulation 39.001 of the Civil Aviation Safety Regulations 1998 allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for types of aircraft or aeronautical products. These ADs, which are considered legislative instruments under section 6 of the Legislative Instruments Act 2003, serve as a key mechanism for ensuring the continuing airworthiness of aircraft, aligning with the responsibilities outlined in Annex 8 to the Convention on International Civil Aviation.
Under these provisions, the State of Design holds the primary responsibility for the continuing airworthiness of an aircraft type and must supply necessary information to the State of Registry to facilitate this. The State of Registry, which in Australia is CASA, is tasked with developing or adopting requirements to ensure the airworthiness of aircraft registered within its jurisdiction. When an AD is issued by a State of Design, such as Japan for the Mitsubishi MU-2B model, CASA is required to assess the information and, if appropriate, issue a corresponding Australian AD to enforce the requirements set forth by the State of Design.
The ADs issued by CASA, such as AD/MU-2/71 for the Mitsubishi MU-2B model, are mandated by Australia's obligations under the Convention on International Civil Aviation and in response to directives from the relevant State of Design. Given the international nature of these directives and their basis in convention obligations, no consultation of the Australian public is required for these ADs, as determined by the Office of Regulatory Review. Furthermore, these ADs do not necessitate a Regulatory Impact Statement. The AD/MU-2/71 was made by the Manager, Airframes in the Manufacturing, Certification and New Technologies Office, on behalf of CASA, in accordance with subsection 84A(2) of the Act.
Failure to comply with the requirements of an AD can lead to serious consequences. Under the Civil Aviation Act 1988, non-compliance can result in both civil and criminal penalties. Civil penalties may include fines, and in severe cases, criminal penalties could be imposed, including imprisonment. The exact penalties are determined based on the severity of the breach and are designed to ensure adherence to safety standards set by CASA and international agreements. These measures underscore the importance of compliance with ADs to maintain the safety and integrity of Australia's aviation system.
