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 Civil Aviation Safety Authority or its predecessors issued AD/AA-1/5 affecting Gulfstream AA-1 model aircraft. CASA has assessed this AD and as a result has cancelled AD/AA-1/5. The cancellation will become effective on 4 June 2009. No replacement AD is required, as the unsafe condition no longer exists.
As this AD has been cancelled because of Australia’s obligations under the Convention on International Civil Aviation, no consultation with the Australian public has taken place on this AD cancellation. 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 Group, on behalf of CASA, in accordance with subsection 84A (2) of the Act.
Overview
The Civil Aviation Act 1988, enacted by the Australian Parliament, aims to regulate civil aviation within Australia, focusing on safety and ensuring the airworthiness of aircraft. In line with this, the Civil Aviation Safety Regulations 1998 empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products, as outlined in regulation 39.001. These ADs serve as legislative instruments, critical for maintaining the safety and airworthiness of aircraft in accordance with international standards, particularly under Annex 8 to the Convention on International Civil Aviation. The cancellation of an airworthiness directive, such as AD/AA-1/5 affecting Gulfstream AA-1 model aircraft, reflects Australia's commitment to international obligations and the ongoing efforts of CASA to ensure that the Australian Register maintains the highest safety standards.
Scope and Application
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 provide the legal framework for the issuance and regulation of airworthiness directives (ADs) in Australia. Under this Act and the Regulations, the Civil Aviation Safety Authority (CASA) has the authority to issue ADs for specific types of aircraft or aeronautical products, in accordance with the safety of air navigation. These directives serve as legislative instruments and are essential for ensuring the continuing airworthiness of aircraft in compliance with international standards set by the Convention on International Civil Aviation. The State of Design holds responsibility for the airworthiness of an aircraft type, while the State of Registry, in this case CASA, must ensure that the aircraft remains airworthy and compliant with Australian regulations. The issuance and cancellation of ADs are typically conducted without public consultation and do not require a Regulatory Impact Statement. CASA issues and manages these directives to maintain the safety and compliance of aircraft within Australia, reflecting the nation's commitment to international aviation safety standards.
Key Provisions
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 together provide the legislative framework for issuing airworthiness directives (ADs). According to section 98 of the Civil Aviation Act 1988, the Governor-General has the authority to make regulations that support the Act and promote the safety of air navigation. Under regulation 39.001 of the Civil Aviation Safety Regulations 1998, the Civil Aviation Safety Authority (CASA) is empowered to issue ADs for specific types of aircraft or aeronautical products to ensure their continuing airworthiness. An AD is considered a legislative instrument under section 6 of the Legislative Instruments Act 2003 and is disallowable under section 46A of the Acts Interpretation Act 1901.
The obligations and requirements imposed by these provisions on the parties involved, particularly CASA, include assessing the need for ADs issued by the State of Design and determining whether to issue an Australian AD to enforce those requirements. CASA, as Australia’s national airworthiness authority, must ensure the continuing airworthiness of aircraft registered in Australia in accordance with Annex 8 to the Convention on International Civil Aviation. This includes evaluating international ADs and deciding whether to implement or cancel them based on the specific circumstances and safety considerations pertinent to Australian operations.
Failure to comply with the requirements of the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 can lead to various civil or criminal consequences. While the text does not specify exact penalties for non-compliance with ADs, breaches of civil aviation regulations can result in significant fines, imprisonment, or both, depending on the severity of the violation. For example, under section 24 of the Civil Aviation Act 1988, a person can be fined up to $22,200 for offences related to airworthiness. In more severe cases, the penalties can extend to fines of up to $222,000 and imprisonment for up to five years, as stipulated under section 27 of the same Act. These penalties underscore the importance of adhering to the ADs and other regulatory requirements to ensure the safety and integrity of the aviation industry.
