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 Japan CAB has issued AD TCD-4889-1-2006 affecting MU-2B model aircraft. Japan is the State of Design for these types. CASA has assessed this AD and has issued Australian AD/MU-2/65, Amendment 1, which will become effective on 9 March 2007. This AD cancels and replaces the previous issue.
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 was enacted to address the need for comprehensive regulation of civil aviation in Australia, ensuring safety and efficiency in air navigation. This Act empowers the Governor-General to make regulations for the safety of air navigation, which is implemented through the Civil Aviation Safety Regulations 1998. Under section 98 of the Act, the Civil Aviation Safety Authority (CASA) is authorised to issue airworthiness directives (ADs) for types of aircraft or aeronautical products, as stipulated in regulation 39.001 of the Civil Aviation Safety Regulations 1998. These ADs are legislative instruments, subject to disallowance and oversight as per the Acts Interpretation Act 1901 and the Legislative Instruments Act 2003. The overarching policy objective is to maintain and enhance the safety of air navigation in accordance with international standards, particularly under Annex 8 to the Convention on International Civil Aviation. CASA's role is to ensure the continuing airworthiness of aircraft registered in Australia, often in response to directives from the State of Design, as demonstrated by the issuance of Australian AD/MU-2/65, Amendment 1, following Japan's AD TCD-4889-1-2006 for MU-2B model aircraft.
Scope and Application
The Civil Aviation Safety Regulations 1998, under the authority of the Civil Aviation Act 1988, empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) concerning specific types of aircraft or aeronautical products. This regulatory mechanism is integral to ensuring the safety of air navigation, aligning with the overarching responsibility of the State of Design to maintain the continuing airworthiness of aircraft types as stipulated by Annex 8 to the Convention on International Civil Aviation. CASA, as Australia's national airworthiness authority, plays a crucial role in this framework by assessing ADs issued by other countries, such as Japan in this instance, and issuing corresponding Australian ADs when necessary. The issuance of Australian AD/MU-2/65, Amendment 1, for the MU-2B model aircraft, is a direct response to AD TCD-4889-1-2006 issued by the Japan Civil Aviation Bureau, reflecting Australia's commitment to international safety standards and obligations under the Convention on International Civil Aviation. This process underscores the collaborative nature of aviation safety regulation, where the specific ADs serve as essential tools for maintaining the airworthiness of aircraft registered in Australia.
Key Provisions
The Civil Aviation Act 1988, specifically section 98, empowers the Governor-General to establish regulations that safeguard air navigation. Under this authority, regulation 39.001 of the Civil Aviation Safety Regulations 1998 allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. These directives are legislative instruments and can be disallowed under section 46A of the Acts Interpretation Act 1901. Such regulations are critical in maintaining the safety standards required under international conventions like Annex 8 to the Convention on International Civil Aviation.
Under these regulations, the State of Design holds primary responsibility for the continuing airworthiness of aircraft types, ensuring that all necessary information is provided to States of Registry to maintain airworthiness. The State of Registry, in turn, is tasked with ensuring the ongoing airworthiness of individual aircraft within its jurisdiction. In practice, when the State of Design issues an AD, CASA, as Australia’s national airworthiness authority, evaluates the information and issues a corresponding Australian AD if necessary. This ensures that Australian-registered aircraft meet international safety standards.
The obligations under these provisions require CASA to rigorously assess and implement ADs issued by other States of Design, ensuring that Australian ADs align with international safety standards. For instance, CASA issued Australian AD/MU-2/65, Amendment 1, following Japan’s AD TCD-4889-1-2006 for MU-2B model aircraft. This AD became effective on 9 March 2007, replacing its predecessor. Given the international nature of these directives and Australia’s obligations under the Convention on International Civil Aviation, no public consultation was required for this AD, and it did not necessitate a Regulatory Impact Statement.
The issuance of ADs and the enforcement of compliance with them are crucial for maintaining the safety of air navigation. Failure to comply with these directives can result in severe consequences, including civil penalties and criminal charges. For example, section 84A(2) of the Civil Aviation Act 1988 allows CASA to take enforcement actions against entities or individuals who do not adhere to airworthiness directives. Penalties for non-compliance can include substantial fines and, in severe cases, imprisonment. Such stringent measures underscore the importance of adhering to airworthiness directives to ensure the highest safety standards in aviation.
