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.
CASA issued AD/PA-23/24 affecting Piper PA-23 model aircraft in 1971. CASA has reviewed this AD and as a result has decided to cancel it. The cancellation will become effective on 3 July 2008. No replacement AD is required, as all affected aircraft would have been modified long ago.
No consultation with the Australian public has taken place on this AD cancellation, because the cancellation results in a reduction of the regulatory burden. 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 was enacted to provide a legislative framework for the regulation of civil aviation in Australia, ensuring the safety and efficiency of air navigation. In line with this, the Civil Aviation Safety Regulations 1998 were established to further detail the regulatory requirements, including the issuance of airworthiness directives (ADs). These directives are critical for maintaining the continuing airworthiness of aircraft and are issued by the Civil Aviation Safety Authority (CASA) under the authority granted by section 39.001 of the regulations. CASA, as Australia's national airworthiness authority, plays a crucial role in ensuring compliance with international standards, particularly those outlined in Annex 8 to the Convention on International Civil Aviation. The policy objective behind these regulations is to ensure that aircraft registered in Australia meet the necessary safety standards, thereby protecting the public and contributing to the safe operation of civil aviation.
Scope and Application
The Civil Aviation Act 1988 and its associated regulations, including the Civil Aviation Safety Regulations 1998, govern the safety of air navigation in Australia. Under these provisions, the Civil Aviation Safety Authority (CASA) has the authority to issue airworthiness directives (ADs), which are legislative instruments that mandate requirements to ensure the continuing airworthiness of aircraft types registered in Australia. The ADs are issued in response to information from the State of Design and are tailored to the specific requirements of aircraft registered in Australia. The Act applies to all aircraft operators, manufacturers, and relevant personnel within Australia, ensuring compliance with safety standards. CASA, as the national airworthiness authority, is responsible for issuing these directives to maintain safety standards, and such directives have a direct impact on the operations of those within the aviation industry. The geographic reach of these regulations is national, applying to all aircraft registered in Australia. However, the application of ADs also aligns with international standards set by the International Civil Aviation Organization (ICAO). While no specific exclusions are mentioned, the issuance and cancellation of ADs are subject to rigorous review and assessment to maintain safety and compliance with both national and international standards.
Key Provisions
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 provide the framework for the issuance and management of airworthiness directives (ADs). Under section 98 of the Civil Aviation Act 1988, the Governor-General has the authority to make regulations for the safety of air navigation, and regulation 39.001 of the Civil Aviation Safety Regulations 1998 grants CASA (Civil Aviation Safety Authority) the power to issue ADs for specific kinds of aircraft or aeronautical products. These directives are essential for ensuring that aircraft and aeronautical products remain airworthy, as they contain mandatory requirements for the ongoing maintenance and safety of these items.
The obligations imposed by these regulations on the parties involved are significant. The State of Design, which is the state where the aircraft type is designed, must provide necessary information to ensure the continuing airworthiness of that aircraft type. This information is crucial for the State of Registry, the state where the individual aircraft is registered, which is responsible for the ongoing airworthiness of that specific aircraft. CASA, as Australia's national airworthiness authority, must assess information provided by the State of Design and issue Australian ADs when necessary to mandate the required safety measures. These obligations ensure that both states and CASA work collaboratively to maintain high safety standards in the aviation sector.
Failure to comply with the requirements set out in ADs can lead to serious consequences. While specific offences and penalties are not detailed in the provided text, non-compliance with ADs can generally result in severe civil and criminal penalties. Such penalties may include fines, imprisonment, or both, depending on the severity of the breach. The exact penalties would be determined based on the specific regulations and the nature of the non-compliance. It is imperative for all parties involved to adhere to the ADs to avoid these potential consequences and ensure the continued safety of aviation operations.
