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 UK CAA has issued AD G-2005-0025 affecting DH 82 model aircraft. The UK is the State of Design for this type. CASA has assessed this AD and has issued Australian AD/DH 82/14, which will become effective on 27 October 2005.
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, enacted to ensure the safety and efficiency of civil aviation in Australia, provides the framework within which the Civil Aviation Safety Regulations 1998 operate. These regulations, particularly regulation 39.001, empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specified types of aircraft or aeronautical products. These ADs serve as legislative instruments, essential for maintaining the continuing airworthiness of aircraft as mandated by Annex 8 of the Convention on International Civil Aviation. In the context of international obligations and to uphold safety standards, CASA is required to issue Australian ADs when corresponding directives are issued by the State of Design, which in this case is the United Kingdom for the DH 82 model aircraft.
Given the nature of ADs and their international basis, the issuing of AD/DH 82/14 by CASA did not necessitate public consultation or a Regulatory Impact Statement, as determined by the Office of Regulatory Review. This directive was made by the Manager, Airframes in the Manufacturing, Certification and New Technologies Office at CASA, under the authority of the Civil Aviation Act 1988. The objective of these regulations and the resultant ADs is to ensure compliance with international standards and the continuing airworthiness of aircraft registered in Australia.
Scope and Application
The Civil Aviation Safety Regulations 1998, under regulation 39.001, empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. These directives are legislative instruments that serve to mandate safety requirements, in line with Australia's obligations under the Convention on International Civil Aviation and its Annex 8. The application of these regulations extends to all aircraft registered in Australia, thereby encompassing both domestic and international entities operating within the Australian airspace. The State of Design, such as the UK in the case of the DH 82 model aircraft, retains the primary responsibility for ensuring the continuing airworthiness of aircraft types, while the State of Registry, represented by CASA in Australia, is tasked with enforcing these directives to ensure compliance. The issuance of Australian ADs is triggered by corresponding directives from the State of Design, and as such, these directives do not undergo public consultation or require a Regulatory Impact Statement, reflecting their urgent safety-focused nature.
Key Provisions
The Civil Aviation Act 1988, through section 98, grants the Governor-General the authority to establish regulations aimed at ensuring the safety of air navigation. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 further empowers the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. These ADs are legally binding and serve as a crucial means of ensuring that aircraft maintain their airworthiness. Under subregulation 39.001(5), ADs are classified as disallowable instruments under the Acts Interpretation Act 1901, and therefore, they are considered legislative instruments in accordance with section 6 of the Legislative Instruments Act 2003.
The obligations imposed by the Act and the Regulations primarily rest on CASA, as Australia’s national airworthiness authority, to ensure that the continuing airworthiness of aircraft is maintained. When an AD is issued by the State of Design, such as the UK in the case of the DH 82 model aircraft, CASA is obligated to assess this information and, if necessary, issue a corresponding Australian AD to enforce the requirements set by the State of Design. The State of Registry, in this instance Australia, is also responsible for ensuring the continuing airworthiness of individual aircraft. This includes adopting or developing necessary requirements and complying with ADs issued by the State of Design. CASA, acting on behalf of Australia, must ensure that these international obligations are met and that Australian aviation standards are upheld.
Breach of the obligations imposed by the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 can lead to various legal consequences. Failure to comply with an AD can result in serious safety issues, potentially leading to aircraft being grounded or prohibited from operation. While the specific penalties for non-compliance are not detailed within the provided text, general aviation regulations may impose fines, suspension of certificates, or other punitive measures against individuals or entities that fail to adhere to airworthiness directives. Such breaches can also lead to civil liability for damages resulting from accidents or incidents caused by non-compliance. In extreme cases, criminal charges may be pursued against those responsible for significant safety violations.
