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 United States FAA has issued AD 2005-23-16 affecting Boeing Model 737 aircraft. The United States is the State of Design for these types. CASA has assessed this AD and has issued Australian AD/B737/274, which will become effective on 16 February 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 Acting 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 provide a legal framework for the regulation of civil aviation in Australia, ensuring the safety and efficiency of air navigation. One of the key provisions of this Act is section 98, which empowers the Governor-General to make regulations for the safety of air navigation, including the issuance of airworthiness directives (ADs) as outlined in the Civil Aviation Safety Regulations 1998. These regulations, particularly regulation 39.001, allow the Civil Aviation Safety Authority (CASA) to issue ADs for specific kinds of aircraft or aeronautical products. This authority is exercised under the oversight of the Legislative Instruments Act 2003, which designates ADs as legislative instruments. The objective of these regulations is to ensure the continuing airworthiness of aircraft, in line with Australia's obligations under the Convention on International Civil Aviation and to comply with the requirements set by the relevant State of Design. The ADs issued by CASA reflect the collaborative efforts between Australia and other contracting states to maintain the safety standards in international civil aviation.
Scope and Application
The Civil Aviation Safety Regulations 1998, under section 39.001, empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) concerning specific types of aircraft or aeronautical products to ensure the safety of air navigation as stipulated in the Civil Aviation Act 1988. These directives, as per subregulation 39.001(5), are considered disallowable instruments under the Acts Interpretation Act 1901, and thus, they fall under the purview of the Legislative Instruments Act 2003 as legislative instruments. The regulations apply to any aircraft registered in Australia and any aeronautical products used on those aircraft, encompassing both individual aircraft and the types they belong to. The geographic reach of these regulations is national, given CASA's role as Australia's national airworthiness authority. The issuance of these directives does not require public consultation due to Australia's international obligations under the Convention on International Civil Aviation, specifically Annex 8, which mandates that the State of Design has overarching responsibility for the continuing airworthiness of aircraft types, necessitating information sharing with States of Registry. The ADs are a standard form of continuing airworthiness information shared among ICAO Contracting States, including the United States, which is the State of Design for Boeing Model 737 aircraft. CASA issues Australian ADs when necessary, as illustrated by the Australian AD/B737/274 issued in response to the United States FAA's AD 2005-23-16.
Key Provisions
The Civil Aviation Act 1988, as amended, and the Civil Aviation Safety Regulations 1998 provide the framework for the regulation of civil aviation in Australia, with specific emphasis on the safety of air navigation and the continuing airworthiness of aircraft. Section 98 of the Act allows the Governor-General to make regulations for the purposes of the Act, which includes ensuring the safety of air navigation. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 empowers the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for certain types of aircraft or aeronautical products. These ADs are legislative instruments, disallowable under section 46A of the Acts Interpretation Act 1901 and subject to the provisions of the Legislative Instruments Act 2003.
In terms of obligations and requirements, the Act and Regulations impose several duties on CASA and other entities. Under Annex 8 to the Convention on International Civil Aviation, the State of Design (in this case, the United States for Boeing 737 aircraft) is responsible for the continuing airworthiness of an aircraft type and must provide necessary information to States of Registry, including Australia. CASA, as the national airworthiness authority, must assess this information and, if deemed appropriate, issue an Australian AD to ensure compliance with the safety standards set by the State of Design. The State of Registry is also responsible for ensuring the continuing airworthiness of individual aircraft by developing or adopting requirements based on the ADs issued.
Failure to comply with an airworthiness directive may result in serious consequences. While the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 do not explicitly detail offences and penalties for non-compliance with ADs, non-compliance can lead to significant legal and safety risks. These risks may include enforcement actions by CASA, potential grounding of the aircraft, and criminal or civil liability under other provisions of the Act. The safety and regulatory framework is designed to ensure that all parties involved in civil aviation adhere to the highest standards of safety and airworthiness.
The legislative process for issuing an AD, as illustrated in the case of AD 2005-23-16 affecting Boeing Model 737 aircraft, involves CASA assessing the information provided by the State of Design and issuing an Australian AD if necessary. The AD is then made by an authorised official of CASA in accordance with the relevant sections of the Civil Aviation Act 1988, without the need for public consultation or a Regulatory Impact Statement, due to its international obligations and the nature of the safety directive. This ensures that Australian aviation standards are harmonised with international practices, maintaining high safety standards across the industry.
