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 German LBA has issued AD 2004-007 affecting Dornier 328 series aircraft. Germany is the State of Design for this series aircraft. CASA has assessed this AD and has issued Australian AD/DO 328/4, which will become effective on 28 November 2005.
As this AD is issued because of Australia’s obligations under the 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, 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 framework for the regulation of civil aviation in Australia, ensuring safety and efficiency within the industry. The Act empowers the Governor-General to make regulations for the purposes of the Act and in the interests of the safety of air navigation, as seen in section 98. The Civil Aviation Safety Regulations 1998 further detail the responsibilities and procedures necessary for maintaining airworthiness, including the issuance of airworthiness directives (ADs) by the Civil Aviation Safety Authority (CASA). This regulatory approach is consistent with Australia's obligations under the Convention on International Civil Aviation, particularly Annex 8, which outlines the responsibilities of the State of Design and the State of Registry regarding the continuing airworthiness of aircraft. The issuance of ADs, such as AD/DO 328/4 for the Dornier 328 series aircraft, is a direct response to international safety requirements and ensures that Australian aircraft meet the necessary safety standards. The ADs are developed without public consultation as they are in line with international obligations and follow the assessment of directives issued by the aircraft's State of Design.
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, ensuring compliance with international standards for aircraft safety. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 empowers the Civil Aviation Safety Authority (CASA) to issue ADs for specific types of aircraft or aeronautical products. These ADs are legislative instruments under the Legislative Instruments Act 2003 and serve to maintain the continuing airworthiness of aircraft as required by Annex 8 to the Convention on International Civil Aviation. The State of Design for an aircraft type has the primary responsibility for ensuring its airworthiness, while the State of Registry must enforce the ADs issued by the State of Design or, if necessary, develop its own requirements. In the case of the German State of Design issuing an AD for Dornier 328 series aircraft, CASA, as Australia’s national airworthiness authority, is mandated to assess and issue corresponding Australian ADs, such as AD/DO 328/4, which are effective from a specified date. Given that these directives are issued in response to international obligations and specific aircraft safety concerns, they do not require public consultation or a Regulatory Impact Statement. The issuance of these directives is overseen by the Manager, New Technologies and Systems, within CASA’s Manufacturing, Certification and New Technologies Office, as per subsection 84A(2) of the Act.
Key Provisions
The key operative sections of this legislation pertain to the issuance of airworthiness directives (ADs) by the Civil Aviation Safety Authority (CASA), as authorised under section 98 of the Civil Aviation Act 1988. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 empowers CASA to issue these directives for specific kinds of aircraft or aeronautical products. Under subregulation 39.001(5), these ADs are considered disallowable instruments under section 46A of the Acts Interpretation Act 1901 and, as such, are legislative instruments under section 6 of the Legislative Instruments Act 2003. The ADs are designed to ensure the continuing airworthiness of aircraft, a responsibility that falls upon the State of Design and the State of Registry under Annex 8 to the Convention on International Civil Aviation.
The obligations imposed by the Act and the Regulations on parties and entities governed by them include the responsibility of the State of Design to provide necessary information for maintaining the airworthiness of aircraft types. The State of Registry, in this case CASA, must assess the information provided by the State of Design and, if necessary, issue corresponding ADs to ensure compliance with airworthiness requirements. This process was followed when the German LBA issued AD 2004-007 concerning Dornier 328 series aircraft, with CASA subsequently issuing Australian AD/DO 328/4. These directives mandate specific actions or checks to be performed on the affected aircraft to maintain their airworthiness.
Failure to comply with the requirements of an AD can lead to significant legal consequences. Under the Civil Aviation Act 1988, non-compliance with an AD can result in civil penalties, which may include fines, and potentially criminal penalties for serious breaches. The exact penalties depend on the severity of the breach and the discretion of the courts, but they can include substantial financial penalties and, in severe cases, imprisonment. Additionally, non-compliance can lead to the grounding of aircraft, which can have severe operational and financial repercussions for airlines and operators.
