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 2008-10-12 affecting Air Tractor AT-800 model aircraft. The USA is the State of Design for this type. CASA has assessed this AD and has issued Australian AD/AT 800/9, Amendment 2, which will become effective on 3 July 2008. 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 Best Practice Regulation has determined that ADs do not require a Regulatory Impact Statement.
The AD has been made by the Manager, Airframes in the Airworthiness Engineering Branch, on behalf of CASA, in accordance with subsection 84A (2) of the Act.
Overview
The Civil Aviation Act 1988, enacted by the Parliament of Australia, serves to regulate civil aviation within Australia with the overarching aim of ensuring the safety of air navigation. This Act empowers the Governor-General to establish regulations in the interest of aviation safety, delegating authority to the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products as stipulated in the Civil Aviation Safety Regulations 1998. These ADs are considered legislative instruments and are integral to maintaining the continuing airworthiness of aircraft, aligning with international standards set by the International Civil Aviation Organization (ICAO).
The issuance of ADs, such as AD/AT 800/9, Amendment 2 for Air Tractor AT-800 model aircraft, reflects Australia's commitment to international aviation safety protocols and obligations under the Convention on International Civil Aviation. This directive, issued by CASA in response to a US Federal Aviation Administration (FAA) AD, is rooted in Australia's responsibilities as the State of Registry and does not require public consultation or a Regulatory Impact Statement, as determined by the Office of Best Practice Regulation. The AD is issued under the authority vested in CASA by the Civil Aviation Act 1988, ensuring that Australian regulatory practices are consistent with international standards and the safety mandates outlined in the Convention.
Scope and Application
The Civil Aviation Act 1988, complemented by the Civil Aviation Safety Regulations 1998, provides the legislative framework through which airworthiness directives (ADs) are issued in Australia. Under this legislation, the Civil Aviation Safety Authority (CASA) has the authority to issue ADs for specific kinds of aircraft or aeronautical products in order to ensure the safety of air navigation. This authority stems from regulation 39.001 of the Civil Aviation Safety Regulations 1998, and these ADs are considered legislative instruments as per subregulation 39.001(5) and section 6 of the Legislative Instruments Act 2003. The application of ADs is particularly relevant to the State of Registry of individual aircraft and the State of Design of aircraft types, aligning with the international obligations under Annex 8 to the Convention on International Civil Aviation. In the case of the Air Tractor AT-800 model aircraft, CASA, as Australia’s national airworthiness authority, has assessed the AD issued by the US Federal Aviation Administration (FAA) and subsequently issued an Australian AD to mandate the requirements for aircraft registered in Australia. Given the international nature and the specific obligations under the Convention on International Civil Aviation, this AD was issued without public consultation and does not require a Regulatory Impact Statement.
Key Provisions
The key provisions of the Civil Aviation Act 1988, specifically regarding the issuance of airworthiness directives (ADs) under section 98, allow the Governor-General to make regulations in the interest of safety in air navigation. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 empowers the Civil Aviation Safety Authority (CASA) to issue ADs for specific kinds of aircraft or aeronautical products. This process is designed to ensure that aircraft maintain their airworthiness in accordance with international standards.
Under the Civil Aviation Safety Regulations 1998, these ADs are legislative instruments, as outlined in section 46A of the Acts Interpretation Act 1901 and section 6 of the Legislative Instruments Act 2003. This means that ADs carry the force of law and are subject to disallowance. The ADs are a critical mechanism for maintaining the continuing airworthiness of aircraft types, as mandated by Annex 8 to the Convention on International Civil Aviation. The State of Design, which is the country where the aircraft type is designed, holds primary responsibility for ensuring the aircraft's continuing airworthiness, while the State of Registry, the country where the aircraft is registered, must implement the necessary measures to uphold these standards.
The obligations imposed by the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 require CASA to assess and, if appropriate, issue Australian ADs in response to ADs issued by the relevant State of Design. This ensures that Australian-registered aircraft comply with international safety standards. For instance, the US Federal Aviation Administration (FAA) issued AD 2008-10-12 concerning Air Tractor AT-800 model aircraft, prompting CASA to issue Australian AD/AT 800/9, Amendment 2, which superseded the previous directive and took effect on 3 July 2008.
In terms of civil and criminal consequences, the Civil Aviation Safety Regulations 1998 do not specify particular offences or penalties for failing to comply with ADs. However, non-compliance with ADs can result in severe repercussions, including the grounding of aircraft, which can have significant operational and financial impacts for airlines and aircraft owners. Furthermore, failure to adhere to ADs can lead to enforcement actions by CASA, which may include fines or other administrative penalties.
