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 German LBA has issued AD 1997-327/3 affecting Dornier 328 model aircraft. Germany is the State of Design for this type. CASA has assessed this AD and has issued Australian AD/DO 328/38, which will become effective on 19 January 2006.
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 establish a legal framework for the regulation of civil aviation in Australia, addressing the need for comprehensive safety standards and operational oversight. It empowers the Governor-General to make regulations for the safety of air navigation, which is integral to ensuring the safe operation of aircraft. The Civil Aviation Safety Regulations 1998, made under this Act, provide mechanisms for the issuance of airworthiness directives by the Civil Aviation Safety Authority (CASA). The authority to issue these directives is grounded in international obligations under Annex 8 to the Convention on International Civil Aviation, which places the responsibility for continuing airworthiness on the State of Design and the State of Registry. Consequently, CASA, as Australia's national airworthiness authority, must assess and, if necessary, mandate the requirements of foreign airworthiness directives for aircraft registered in Australia. This ensures compliance with international safety standards and the safe operation of aircraft within Australian airspace.
Scope and Application
The Civil Aviation Act 1988, supplemented by the Civil Aviation Safety Regulations 1998, governs the issuance of airworthiness directives (ADs) in Australia, with the objective of ensuring the safety of air navigation. Under regulation 39.001, the Civil Aviation Safety Authority (CASA) has the authority to issue ADs for specific types of aircraft or aeronautical products. These ADs are considered legislative instruments and are subject to disallowance as per section 46A of the Acts Interpretation Act 1901 and the Legislative Instruments Act 2003. The ADs are crucial for maintaining the continuing airworthiness of aircraft, as stipulated in Annex 8 of the Convention on International Civil Aviation, where the State of Design bears the responsibility for providing necessary information to the States of Registry. In Australia, CASA, as the national airworthiness authority, assesses ADs issued by the States of Design and, if necessary, issues corresponding Australian ADs to enforce these requirements. For instance, CASA issued Australian AD/DO 328/38 in response to German LBA's AD 1997-327/3 concerning Dornier 328 model aircraft. This process adheres to Australia’s international obligations and does not require public consultation or a Regulatory Impact Statement, as determined by the Office of Regulatory Review.
Key Provisions
The key operative sections of the Civil Aviation Act 1988, particularly section 98, empower the Governor-General to enact regulations for air navigation safety, thereby enabling the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) under regulation 39.001 of the Civil Aviation Safety Regulations 1998. These ADs, which are legislative instruments as per section 6 of the Legislative Instruments Act 2003, play a crucial role in ensuring the safety and airworthiness of aircraft. Subregulation 39.001(5) further underscores the formal status of ADs as disallowable instruments under the Acts Interpretation Act 1901.
The obligations imposed by these provisions necessitate that CASA, as Australia's national airworthiness authority, closely collaborates with the State of Design and the State of Registry to maintain the continuing airworthiness of aircraft types registered in Australia. Specifically, when a State of Design issues an AD for a particular aircraft type, CASA must assess the information and, if necessary, issue a corresponding Australian AD. This ensures that the safety standards set by the State of Design are effectively implemented in Australia. For instance, following the German LBA's issuance of AD 1997-327/3 for the Dornier 328 model, CASA issued Australian AD/DO 328/38 to align with international standards and obligations under the Convention on International Civil Aviation.
In terms of consequences, breaches of these regulations can lead to significant penalties. Under section 34 of the Civil Aviation Act 1988, non-compliance with an AD can result in substantial fines and imprisonment, reflecting the critical nature of these safety measures. The maximum penalty for such offences can be up to $210,000 for individuals and $1,050,000 for bodies corporate, highlighting the serious implications of failing to adhere to the mandated safety protocols. Additionally, CASA has the authority to suspend or revoke airworthiness certificates for non-compliance, which can have severe operational consequences for airlines and aircraft operators.
In summary, the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 establish a robust framework for maintaining airworthiness through the issuance of ADs. CASA's role in assessing and implementing these directives ensures that Australian-registered aircraft meet international safety standards. The stringent penalties for non-compliance underscore the importance of adhering to these regulations, thereby safeguarding the safety of air navigation.
