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 UK CAA has issued AD 006-05-96 affecting BAe Jetstream 4100 model aircraft. The UK is the State of Design for this type. CASA has assessed this AD and has issued Australian AD/J4100/9, which will become effective on 20 February 2008.
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, addresses the regulation of civil aviation in the country with a focus on safety and efficiency. The Act provides the framework for establishing and enforcing safety standards, including the issuance of airworthiness directives (ADs) by the Civil Aviation Safety Authority (CASA) to ensure the continuing airworthiness of aircraft. Under section 98 of the Act, the Governor-General has the authority to make regulations, including ADs, in the interests of air navigation safety. This legislation was introduced to fill the need for a cohesive regulatory approach to civil aviation safety, aligning with international standards as set by the Convention on International Civil Aviation. The Civil Aviation Safety Regulations 1998, which operate under the authority of the Civil Aviation Act, further detail the process and requirements for issuing ADs. The policy objective is to maintain and enhance the safety of civil aviation through consistent and enforceable airworthiness standards.
Scope and Application
The Civil Aviation Act 1988 applies to the regulation and safety of civil aviation in Australia, with specific focus on the issuance of airworthiness directives (ADs) under regulation 39.001 of the Civil Aviation Safety Regulations 1998. The Act empowers the Civil Aviation Safety Authority (CASA) to issue ADs for specific kinds of aircraft or aeronautical products to ensure the continuing airworthiness of aircraft registered in Australia. These ADs are legislative instruments under the Legislative Instruments Act 2003, and their issuance is governed by international standards, particularly Annex 8 to the Convention on International Civil Aviation. The ADs are issued by the State of Design, and CASA, as Australia's national airworthiness authority, must assess these directives and, if necessary, issue corresponding Australian ADs. This ensures compliance with international obligations and the maintenance of air safety standards. The process of issuing these ADs does not require public consultation or a Regulatory Impact Statement, as determined by the Office of Best Practice Regulation. The ADs are issued by CASA officials, such as the Manager, Airframes in the Airworthiness Engineering Branch, in accordance with the Act.
Key Provisions
The Civil Aviation Safety Regulations 1998 (Regulation 39.001) provide the authority for the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs). These directives are legislative instruments under the Legislative Instruments Act 2003 and are essential tools for maintaining the continuing airworthiness of aircraft. In the case of the BAe Jetstream 4100 model aircraft, CASA has issued AD/J4100/9 in response to the UK Civil Aviation Authority's (CAA) AD 006-05-96. This action aligns with Australia's obligations under the Convention on International Civil Aviation, specifically Annex 8, which assigns the State of Design the responsibility for continuing airworthiness. In this scenario, the UK is the State of Design, and CASA, as Australia's national airworthiness authority, is the State of Registry.
The obligations under the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 require CASA to evaluate and, when necessary, issue ADs to ensure that aircraft meet the required safety standards. This includes assessing ADs issued by other states and determining whether they should be mandated in Australia. For the BAe Jetstream 4100 model, CASA's role is to ensure that the Australian AD/J4100/9 incorporates the necessary safety measures to maintain the continuing airworthiness of the aircraft registered in Australia. Additionally, the State of Registry must develop or adopt requirements to ensure the continuing airworthiness of aircraft, which CASA enforces through the issuance of ADs.
The Civil Aviation Safety Regulations 1998 and the Legislative Instruments Act 2003 establish the legal framework for issuing ADs, but also include provisions for their disallowance. In the case of ADs issued in response to international obligations and based on directives from the State of Design, such as the UK CAA's AD 006-05-96, no consultation of the Australian public is required. Similarly, the Office of Best Practice Regulation has determined that ADs do not require a Regulatory Impact Statement, simplifying the process for issuing such directives. The AD/J4100/9, issued by CASA, mandates compliance with the safety requirements specified in the UK AD, and will become effective on 20 February 2008.
Breaches of the requirements set out in airworthiness directives can result in significant consequences. Under the Civil Aviation Act 1988, failure to comply with an AD can lead to civil penalties, including fines, and in severe cases, criminal charges. The maximum penalties for non-compliance can be substantial, reflecting the serious implications for public safety that can arise from operating an aircraft that does not meet the required airworthiness standards. The specific penalties depend on the nature and severity of the breach, but can include fines of up to $1,650,000 for corporations and $330,000 for individuals, as well as potential imprisonment for criminal offences. It is therefore crucial for all parties governed by the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 to adhere strictly to the requirements set out in ADs to ensure the safety of air navigation.
