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/PA-31/1 affecting Piper PA-31 aircraft. CASA has reviewed this AD and as a result has cancelled it. The cancellation will become effective on 31 July 2008. 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, 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 Commonwealth Parliament, aims to ensure the safety of air navigation through various regulations and provisions. Under the Act, the Governor-General is empowered to issue regulations that support the overarching goal of air safety, with the Civil Aviation Safety Regulations 1998 being a significant component in this framework. Specifically, regulation 39.001 enables the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for particular types of aircraft or aeronautical products, thus ensuring that the aircraft meet safety standards. This regulatory approach aligns with international standards, such as Annex 8 to the Convention on International Civil Aviation, which mandates the State of Design's responsibility for the continuing airworthiness of an aircraft type and the State of Registry's obligation to ensure the ongoing airworthiness of individual aircraft. Given these international obligations, CASA has the authority to cancel existing ADs, such as AD/PA-31/1 affecting Piper PA-31 aircraft, without the need for public consultation or a Regulatory Impact Statement. The cancellation of this particular AD, effective from 31 July 2008, signifies CASA's adherence to international obligations and its commitment to maintaining the highest safety standards in civil aviation.
Scope and Application
The Civil Aviation Act 1988, as supplemented by the Civil Aviation Safety Regulations 1998, provides the legislative framework for the regulation of civil aviation safety in Australia. Under this framework, the Civil Aviation Safety Authority (CASA) is empowered to issue airworthiness directives (ADs) for specific kinds of aircraft or aeronautical products to ensure the safety of air navigation. These ADs are designed to address safety issues and maintain the continuing airworthiness of aircraft. Notably, an AD is a legislative instrument and is subject to disallowance under the Acts Interpretation Act 1901 and the Legislative Instruments Act 2003. The ADs are integral to fulfilling Australia's commitments under the Convention on International Civil Aviation, particularly those related to the continuing airworthiness of aircraft as overseen by the State of Design and the State of Registry. In the case of the AD affecting Piper PA-31 aircraft, CASA has cancelled the directive, reflecting its obligations under international conventions, and this cancellation does not require public consultation or a Regulatory Impact Statement. The AD was issued by the Manager, Airframes in the Airworthiness Engineering Branch on behalf of CASA, in accordance with the Act.
Key Provisions
Under section 98 of the Civil Aviation Act 1988, the Governor-General is empowered to establish regulations aimed at ensuring the safety of air navigation. This provision is foundational, as it grants the authority to create detailed rules and standards necessary for maintaining the safety of aviation operations. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 specifically allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for particular types of aircraft or aeronautical products. These ADs are designed to address safety issues and ensure that aircraft remain airworthy. According to subregulation 39.001(5), an AD is considered a disallowable instrument, which means it can be reviewed and potentially disallowed by Parliament under section 46A of the Acts Interpretation Act 1901. Additionally, as per section 6 of the Legislative Instruments Act 2003, an AD is classified as a legislative instrument, thereby necessitating adherence to the processes governing legislative instruments.
The obligations imposed by the Act and its associated regulations on the parties and entities it governs are substantial. The State of Design, which is the country where an aircraft type is designed, has the overarching responsibility for ensuring the continuing airworthiness of that aircraft type, as stipulated in Annex 8 to the Convention on International Civil Aviation. This includes providing all necessary information to the appropriate States of Registry to maintain the airworthiness of the aircraft. Similarly, the State of Registry, which is the country where the individual aircraft is registered, must develop or adopt specific requirements to ensure that the aircraft remains airworthy. CASA, as the regulatory body in Australia, plays a critical role in enforcing these obligations by issuing ADs and ensuring compliance with international standards.
Breaches of the requirements set forth in the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 can lead to significant consequences. While the specific offences and penalties are not detailed in the provided text, it is evident that non-compliance with ADs or failure to maintain airworthiness could result in severe civil or criminal penalties. These penalties could include fines, imprisonment, or both, depending on the severity of the breach and the specific provisions of the Act or regulations. The legislative framework ensures that safety standards are rigorously enforced to protect the public and maintain the integrity of the aviation industry.
