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, the Civil Aviation Safety Authority (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.
CASA or its predecessors issued AD/R22/17 affecting Robinson R22 helicopters. CASA has reviewed this AD and as a result has cancelled it. The cancellation will become effective on 7 May 2009. No replacement AD is required.
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 was enacted to provide a legislative framework for the regulation of civil aviation in Australia, ensuring safety and efficiency in air navigation. It empowers the Governor-General to make regulations, such as those found in the Civil Aviation Safety Regulations 1998, which delegate to the Civil Aviation Safety Authority (CASA) the authority to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. These directives, classified as legislative instruments, are essential for maintaining the continuing airworthiness of aircraft as mandated by Annex 8 to the Convention on International Civil Aviation. The State of Registry holds responsibility for individual aircraft, ensuring compliance with these directives, while the State of Design provides necessary information for maintaining airworthiness across contracting states. CASA issued and subsequently cancelled AD/R22/17, affecting Robinson R22 helicopters, due to Australia’s international obligations, without necessitating public consultation or a Regulatory Impact Statement. The cancellation of this AD was executed by the Manager, Systems and New Technologies in the Airworthiness Engineering Group on behalf of CASA, in accordance with the Act.
Scope and Application
The Civil Aviation Act 1988, supplemented by the Civil Aviation Safety Regulations 1998, establishes the legal framework for the regulation of airworthiness directives (ADs) in Australia, thereby ensuring the safety of air navigation. This Act applies to the Civil Aviation Safety Authority (CASA), which is authorised under regulation 39.001 to issue ADs for specific kinds of aircraft or aeronautical products. ADs are considered legislative instruments, as per subregulation 39.001(5) and section 46A of the Acts Interpretation Act 1901, and they are further regulated under section 6 of the Legislative Instruments Act 2003. The ADs issued by CASA serve to maintain the continuing airworthiness of aircraft, a responsibility that ultimately lies with the State of Registry, as outlined in Annex 8 to the Convention on International Civil Aviation. This jurisdictional scope is broad, applying nationally to all entities involved in civil aviation within Australia. The Act does not explicitly state exclusions, exemptions, or specific thresholds for its application, but its overarching aim is to uphold safety standards in line with international conventions. The regulatory process for ADs may be extended or refined through subordinate instruments, ensuring that the safety measures remain current and effective.
Key Provisions
The Civil Aviation Act 1988 (section 98) and the Civil Aviation Safety Regulations 1998 (regulation 39.001) provide the legal framework for the issuance of airworthiness directives (ADs) by the Civil Aviation Safety Authority (CASA). An AD, as defined in subregulation 39.001(5) of the Civil Aviation Safety Regulations 1998, is a disallowable instrument under the Acts Interpretation Act 1901 and is considered a legislative instrument according to section 6 of the Legislative Instruments Act 2003. The State of Design has the overarching responsibility for ensuring the continuing airworthiness of an aircraft type, as stipulated in Annex 8 to the Convention on International Civil Aviation, and must provide necessary information to the State of Registry. The State of Registry, in turn, is responsible for ensuring the continuing airworthiness of individual aircraft.
The obligations imposed by these regulations require CASA to issue ADs that address the safety of air navigation, with specific ADs targeting particular kinds of aircraft or aeronautical products. CASA must ensure that ADs comply with Australia's obligations under the Convention on International Civil Aviation. The cancellation of AD/R22/17, which affected Robinson R22 helicopters, is an example of CASA exercising its authority to withdraw an AD that no longer meets safety standards or aligns with international obligations.
The issuance and cancellation of ADs are significant actions that have legal and practical implications. CASA, as the regulatory body, must adhere to the procedural requirements set out in the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998. Given that ADs are legislative instruments, they must be created in accordance with the legislative process outlined in these acts. The cancellation of AD/R22/17 was determined by CASA based on Australia's international obligations, and no public consultation was necessary as per the Office of Best Practice Regulation's assessment that ADs do not require a Regulatory Impact Statement.
The consequences of failing to comply with the provisions of the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 can be severe. Breaches of these regulations may lead to civil or criminal penalties, depending on the nature and severity of the non-compliance. The specific penalties are not detailed in the text, but they can include fines or other sanctions as prescribed by the relevant legislation. The issuance of ADs and their subsequent cancellation must be handled with due diligence to avoid any legal repercussions and to maintain the safety standards required under international aviation law.
