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 Transport Canada has issued AD CF-1985-08R4 affecting DHC-2 model aircraft. Canada is the State of Design for this type. CASA has assessed this AD and has issued Australian AD/DHC-2/24, Amendment 4, which will become effective on 15 March 2007. 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 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 by the Parliament of Australia, was introduced to ensure the safety and efficiency of civil aviation within Australia. This Act empowers the Governor-General to create regulations that contribute to the safety of air navigation, including the issuance of airworthiness directives (ADs) by the Civil Aviation Safety Authority (CASA) to ensure the continuing airworthiness of aircraft. These ADs are crucial for maintaining safety standards in alignment with international agreements, such as Annex 8 to the Convention on International Civil Aviation, which designates the State of Design as responsible for the ongoing airworthiness of an aircraft type. The policy objective of these regulations is to ensure that all aircraft operating in Australia meet the necessary safety standards as dictated by international and domestic regulations. The Civil Aviation Safety Regulations 1998 further detail the process for issuing ADs, ensuring that they are compliant with Australian law and international obligations.
Scope and Application
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 collectively establish the framework for the regulation of civil aviation in Australia, with particular emphasis on ensuring the safety of air navigation. Under this framework, the Civil Aviation Safety Authority (CASA) is empowered to issue airworthiness directives (ADs) concerning specific types of aircraft or aeronautical products. These directives, which are legislative instruments, play a crucial role in maintaining the continuing airworthiness of aircraft, as mandated by Australia's obligations under international conventions such as the Convention on International Civil Aviation. The State of Registry for an aircraft holds the responsibility for its ongoing airworthiness, and CASA, acting on behalf of Australia, assesses and issues ADs to ensure compliance with international standards. This process is conducted without public consultation or the need for a Regulatory Impact Statement, reflecting the nature of these directives as technical and safety-focused rather than policy-driven. The issuance of ADs, such as the recent Australian AD/DHC-2/24, Amendment 4, is a direct response to international airworthiness directives issued by the State of Design, in this case, Transport Canada, and is made under the authority granted by the Civil Aviation Act 1988.
Key Provisions
The Civil Aviation Act 1988, as supplemented by the Civil Aviation Safety Regulations 1998, empowers the Governor-General to create regulations that promote the safety of air navigation. Under this legislative framework, specifically through regulation 39.001, the Civil Aviation Safety Authority (CASA) is authorised to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. Section 98 of the Act provides the basis for this regulatory authority, ensuring that safety standards are met through the issuance of ADs. Furthermore, subregulation 39.001(5) identifies ADs as disallowable instruments, classifying them as legislative instruments under section 6 of the Legislative Instruments Act 2003.
The obligations placed on parties by these regulations are significant. For instance, the State of Design, which is responsible for the continuing airworthiness of a particular aircraft type, must furnish necessary information to the States of Registry, which in turn must develop or adopt requirements to ensure the continuing airworthiness of aircraft registered within their jurisdiction. When a State of Design issues an AD, the corresponding State of Registry, such as CASA in Australia, must assess the information provided and, if deemed necessary, issue a corresponding AD to enforce the requirements of the State of Design. This ensures that aircraft registered in Australia meet international safety standards.
Failure to comply with airworthiness directives can result in serious legal consequences. Under the Civil Aviation Act 1988, non-compliance with an AD can be considered an offence. The maximum penalties for such offences can include substantial fines and, in severe cases, imprisonment. These stringent measures underscore the importance of adhering to airworthiness directives to maintain the highest safety standards in civil aviation.
Additionally, the process of issuing airworthiness directives is governed by international conventions, notably Annex 8 to the Convention on International Civil Aviation. This convention mandates that the State of Design provide continuing airworthiness information to the States of Registry, facilitating international cooperation in maintaining aviation safety. In cases where ADs are issued in response to actions by the State of Design, such as the Transport Canada's AD CF-1985-08R4 affecting DHC-2 model aircraft, Australia's CASA must act promptly to assess and, if necessary, issue a corresponding Australian AD. This ensures that aircraft operating within Australia meet the stringent safety standards set by international agreements.
