CIVIL AVIATION ACT 1988
CIVIL AVIATION 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-2005-14 affecting Bombardier DHC-8-400 series aircraft. Canada is the State of Design for these types. CASA has assessed this AD and has issued Australian AD/DHC-8/101, which will become effective on 7 July 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 Section Head - Systems, Airworthiness Standards Branch, Standards Division, on behalf of CASA, in accordance with subsection 84A (2) of the Act.
Overview
The Civil Aviation Act 1988 was enacted to address the need for comprehensive regulation of civil aviation in Australia, ensuring safety and efficiency in the national airspace. This legislation empowers the Governor-General to make regulations for the Act's purposes, particularly for the safety of air navigation. In line with this objective, regulation 39.001 of the Civil Aviation Safety Regulations 1998 allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. These ADs, being legislative instruments, serve as crucial tools for maintaining the continuing airworthiness of aircraft, a responsibility shared between the State of Design and the State of Registry, as stipulated under Annex 8 to the Convention on International Civil Aviation. CASA, as Australia’s national airworthiness authority, assesses and, if necessary, issues Australian ADs to ensure compliance with international standards and obligations. The issuance of the Australian AD/DHC-8/101 in response to Transport Canada’s AD CF-2005-14 exemplifies this collaborative approach to aviation safety.
Scope and Application
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 collectively provide the legislative framework for the issuance of airworthiness directives (ADs) in Australia, aimed at ensuring the safety of air navigation. Under these regulations, the Civil Aviation Safety Authority (CASA) can issue ADs for specific types of aircraft or aeronautical products, which are considered legislative instruments. These directives are crucial for maintaining the continuing airworthiness of aircraft, a responsibility that falls on the State of Design and the State of Registry as per Annex 8 to the Convention on International Civil Aviation. CASA, as Australia's national airworthiness authority, plays a pivotal role in assessing and implementing these directives when they affect aircraft registered in Australia. For instance, CASA has issued an Australian AD in response to an AD issued by Canada, the State of Design, for Bombardier DHC-8-400 series aircraft. This process underscores the importance of international cooperation in maintaining aviation safety standards. Importantly, this AD was issued without public consultation and does not require a Regulatory Impact Statement, reflecting its alignment with international obligations and the specific nature of its application.
Key Provisions
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 provide the framework for the issuance of airworthiness directives (ADs) by the Civil Aviation Safety Authority (CASA). Section 98 of the Civil Aviation Act 1988 empowers the Governor-General to make regulations for the safety of air navigation, and regulation 39.001 of the Civil Aviation Safety Regulations 1998 specifically allows CASA to issue ADs for kinds of aircraft or aeronautical products. These ADs are considered legislative instruments under the Legislative Instruments Act 2003, as they are disallowable instruments under section 46A of the Acts Interpretation Act 1901.
The obligations imposed by these provisions require CASA to issue ADs when the State of Design issues an AD affecting aircraft on the Australian Register. CASA must assess the information provided by the State of Design and, if appropriate, issue an Australian AD to mandate the requirements. For instance, Transport Canada has issued AD CF-2005-14 affecting Bombardier DHC-8-400 series aircraft. CASA has assessed this AD and has issued Australian AD/DHC-8/101, which will become effective on 7 July 2005. The State of Registry, which in this case is Australia, must also ensure the continuing airworthiness of the aircraft in accordance with Annex 8 to the Convention on International Civil Aviation.
Failure to comply with an AD can result in severe consequences. Under section 98 of the Civil Aviation Act 1988, CASA may issue fines and penalties for non-compliance with ADs. The specific penalties for breaches of ADs are not detailed in the provided text, but they can include fines, imprisonment, or both, depending on the severity of the breach and the discretion of the court. Additionally, failure to comply with an AD can lead to the grounding of the aircraft, which can have significant operational and financial implications for the aircraft operator.
In summary, the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 establish a framework for the issuance of ADs by CASA to ensure the safety and airworthiness of aircraft on the Australian Register. CASA must issue ADs in response to ADs issued by the State of Design, and operators must comply with these ADs to avoid penalties and ensure the continuing airworthiness of their aircraft. The obligations and consequences of non-compliance are serious, highlighting the importance of adhering to ADs.
