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 US FAA has issued AD 91-22-08 affecting Boeing 727 model aircraft. The USA is the State of Design for this type. CASA has assessed this AD and has issued Australian AD/B727/197, 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 was enacted to establish a legal framework for ensuring the safety and efficiency of civil aviation within Australia. One of its key provisions is section 98, which allows the Governor-General to make regulations in the interests of air navigation safety. Complementing this, the Civil Aviation Safety Regulations 1998 include regulation 39.001, empowering the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. This legislative mechanism is integral to maintaining the continuing airworthiness of aircraft, as mandated by international standards set out in Annex 8 to the Convention on International Civil Aviation. In this context, CASA, as Australia's national airworthiness authority, is obligated to respond to ADs issued by the State of Design, ensuring that Australian registered aircraft meet international safety standards. The ADs are legislative instruments, disallowable under section 46A of the Acts Interpretation Act 1901, and are typically issued without public consultation due to their alignment with international obligations and immediate safety concerns.
Scope and Application
The Civil Aviation Safety Regulations 1998, under the Civil Aviation Act 1988, enable the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) to ensure the continuing airworthiness of aircraft and aeronautical products registered in Australia. These regulations apply to all aircraft and aeronautical products within the Australian jurisdiction, with CASA mandated to assess and potentially issue Australian ADs in response to ADs issued by the State of Design, such as the United States Federal Aviation Administration (FAA). The issuance of these ADs is governed by international obligations under the Convention on International Civil Aviation, which places the responsibility on the State of Design to provide necessary information for continuing airworthiness. CASA’s role as Australia’s national airworthiness authority involves evaluating such information and enforcing compliance through Australian ADs, thereby ensuring that all aircraft registered in Australia meet the required safety standards. While ADs are legislative instruments, they are issued without public consultation or the need for a Regulatory Impact Statement, reflecting their technical nature and the urgency of addressing safety concerns.
Key Provisions
The primary sections of relevance here are section 98 of the Civil Aviation Act 1988 and regulation 39.001 of the Civil Aviation Safety Regulations 1998. Section 98 allows the Governor-General to make regulations for the purposes of the Act, particularly in relation to the safety of air navigation, while regulation 39.001 grants the Civil Aviation Safety Authority (CASA) the authority to issue airworthiness directives (ADs) for certain types of aircraft or aeronautical products. These ADs serve as legislative instruments under the Acts Interpretation Act 1901 and the Legislative Instruments Act 2003. The ADs aim to ensure the continuing airworthiness of aircraft and aeronautical products, mandated by international standards set out in Annex 8 to the Convention on International Civil Aviation.
Under these provisions, the State of Registry, in this case CASA, is responsible for the continuing airworthiness of aircraft registered in Australia. This includes assessing and, if necessary, issuing ADs based on those issued by the State of Design. For instance, the US Federal Aviation Administration (FAA) issued AD 91-22-08 concerning Boeing 727 model aircraft, and CASA has subsequently issued Australian AD/B727/197 to comply with these international obligations. The ADs are not subject to public consultation or a Regulatory Impact Statement as they are issued in response to international agreements and to ensure the safety of air navigation.
Breaching the requirements outlined in these ADs can result in significant consequences. Failure to comply with the ADs could lead to the grounding of affected aircraft, which would have severe operational and financial implications for airlines. In terms of legal consequences, the Civil Aviation Act 1988 and associated regulations might include provisions for fines, penalties, or other enforcement actions against entities or individuals who fail to comply with the ADs. The specific penalties would depend on the nature and severity of the non-compliance, but they are intended to ensure that air safety standards are upheld. It is essential for all relevant parties to adhere to these directives to maintain the high safety standards required by international and domestic aviation regulations.
