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 Brazilian ANAC has issued AD 2006-11-02R3 affecting Embraer ERJ 170 model aircraft. Brazil is the State of Design for these types. CASA has assessed this AD and has issued Australian AD/ERJ-170/4, Amendment 4, which will become effective on 18 June 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, Systems and New Technologies in the Airworthiness Engineering Branch, on behalf of CASA, in accordance with subsection 84A (2) of the Act.
Overview
The Civil Aviation Act 1988 was enacted to provide a legislative framework for the regulation of civil aviation in Australia, ensuring safety and efficiency in air navigation. Under this Act, the Governor-General has the authority to make regulations to promote the safety of air navigation, with the Civil Aviation Safety Regulations 1998 detailing the mechanisms through which these regulations can be implemented. One such regulation is the issuance of airworthiness directives (ADs), which are legislative instruments that mandate specific requirements to ensure the continuing airworthiness of aircraft types. The Civil Aviation Safety Authority (CASA), acting as Australia's national airworthiness authority, assesses and issues these ADs, particularly when they are issued by the State of Design in accordance with international obligations under the Convention on International Civil Aviation. The issuance of ADs such as the Australian AD/ERJ-170/4, Amendment 4, reflects the need to align with international standards and ensure the safety of aircraft registered in Australia.
Scope and Application
The Civil Aviation Act 1988, in conjunction with the Civil Aviation Safety Regulations 1998, provides the legal framework for the issuance of airworthiness directives (ADs) in Australia. These directives are applicable to all aircraft and aeronautical products registered in Australia, encompassing both civilian and commercial entities involved in air navigation. The regulations empower the Civil Aviation Safety Authority (CASA) to issue ADs for specific types of aircraft or aeronautical products, reflecting Australia's commitment to international safety standards as stipulated in Annex 8 to the Convention on International Civil Aviation. The ADs serve as legislative instruments and are subject to disallowance under section 46A of the Acts Interpretation Act 1901. This legislative approach ensures that CASA, acting on behalf of the Australian government, can mandate airworthiness requirements derived from international directives, thereby maintaining the safety and reliability of aircraft operating within Australia. The application of ADs extends nationally, aligning with the jurisdictional reach of the Civil Aviation Act, and is subject to specific exclusions or exemptions as determined by CASA in accordance with the overarching safety regulations.
Key Provisions
The Civil Aviation Safety Regulations 1998 (section 39.001) allow the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. These ADs are legal instruments (section 46A of the Acts Interpretation Act 1901) and are created under the authority of the Civil Aviation Act 1988 (section 98). An AD is essentially a formal notification from CASA that mandates certain actions to ensure the continuing airworthiness of an aircraft. For instance, if the State of Design issues an AD for a particular aircraft type, CASA must review this directive and, if deemed necessary, issue a corresponding AD for Australian-registered aircraft of that type. This ensures that Australian aircraft meet international safety standards.
The obligations under these regulations require CASA to act promptly in response to ADs issued by the State of Design. For example, when the Brazilian National Civil Aviation Agency (ANAC) issued AD 2006-11-02R3 for Embraer ERJ 170 model aircraft, CASA was obligated to assess this directive and issue an Australian AD (AD/ERJ-170/4, Amendment 4) to mandate the required actions for Australian operators. This process ensures that all aircraft registered in Australia comply with the necessary safety standards set forth by international agreements, such as Annex 8 to the Convention on International Civil Aviation.
Failure to comply with the requirements outlined in an AD can lead to serious consequences. Under the Civil Aviation Act 1988, operators who do not adhere to the mandated actions specified in an AD may face penalties. These can include substantial fines and, in severe cases, the grounding of non-compliant aircraft. Such penalties serve as a deterrent to non-compliance and ensure that safety standards are maintained across the board. Additionally, CASA has the authority to take enforcement actions against operators who fail to comply with ADs, further emphasising the importance of adherence to these directives.
In summary, the Civil Aviation Safety Regulations 1998 empower CASA to issue ADs that are essential for maintaining the safety of aircraft registered in Australia. These ADs must be issued in response to directives from the State of Design and are subject to rigorous assessment by CASA. The obligations imposed by these regulations ensure that Australian aircraft meet international safety standards, and failure to comply with ADs can result in significant penalties, including fines and the grounding of aircraft. This regulatory framework is designed to protect public safety and uphold the highest standards of airworthiness.
