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-5/16 Amendment 1 affecting Gulfstream AA-5A aircraft. CASA has assessed this AD and as a result has cancelled Australian AD/AA-5/16 Amendment 1. The cancellation will become effective on 13 March 2008. 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 Acting Manager, Systems and New Technologies 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 framework for the regulation of civil aviation in Australia, ensuring the safety and efficiency of air navigation. Under this Act, the Governor-General has the authority to make regulations for the safety of air navigation, and the Civil Aviation Safety Regulations 1998 further detail the procedures for maintaining airworthiness of aircraft and aeronautical products, including the issuance of airworthiness directives (ADs). These directives serve as crucial mechanisms for maintaining the safety of aircraft, aligning with international standards set by the Convention on International Civil Aviation. The Civil Aviation Safety Authority (CASA) is responsible for assessing and implementing these directives when necessary, ensuring that Australian-registered aircraft meet the required safety standards. This legislative framework underscores Australia's commitment to international aviation safety protocols and the importance of maintaining the continuing airworthiness of aircraft.
Scope and Application
The Civil Aviation Act 1988 and its associated Civil Aviation Safety Regulations 1998 provide the legislative framework under which the Civil Aviation Safety Authority (CASA) can issue airworthiness directives (ADs) to ensure the safety of air navigation. The authority to issue ADs is derived from regulation 39.001 of the Civil Aviation Safety Regulations 1998, which allows CASA to mandate safety requirements for types of aircraft or aeronautical products. These directives are legislative instruments that must be made in accordance with the legislative process outlined in the Legislative Instruments Act 2003. ADs serve as the primary mechanism for communicating continuing airworthiness information as per Annex 8 of the Convention on International Civil Aviation. The State of Design has the responsibility to ensure the continuing airworthiness of an aircraft type, while the State of Registry, in this case CASA as Australia's national airworthiness authority, is tasked with ensuring the airworthiness of individual aircraft on the Australian register. The ADs issued by CASA are subject to international standards and obligations, and the process for issuing, amending, or cancelling these directives reflects Australia's commitments under the Convention on International Civil Aviation.
Key Provisions
The Civil Aviation Act 1988, specifically under section 98, empowers the Governor-General to create regulations aimed at enhancing the safety of air navigation. This authority extends to the Civil Aviation Safety Regulations 1998, where regulation 39.001 allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. According to subregulation 39.001(5), these ADs are considered disallowable instruments under section 46A of the Acts Interpretation Act 1901 and, therefore, are legislative instruments as per section 6 of the Legislative Instruments Act 2003.
The obligations imposed by the Civil Aviation Act and its regulations are primarily centred on ensuring the safety and continuing airworthiness of aircraft. The State of Design, which is responsible for the overall airworthiness of a particular aircraft type, must provide all necessary information to ensure that the aircraft type can maintain its airworthiness. The State of Registry, which is the country that registers an individual aircraft, must develop or adopt requirements to ensure the continuing airworthiness of that aircraft. When a State of Design issues an AD for a type of aircraft on the Australian Register, CASA, as Australia’s national airworthiness authority, is required to assess the AD and, if appropriate, issue an Australian AD to enforce the requirements of the State of Design.
Failure to comply with the requirements set forth by ADs can result in serious consequences. Under the Civil Aviation Act 1988, any violations of the ADs can lead to civil or criminal penalties. The specific nature of these penalties can vary, but they can include substantial fines and, in some cases, imprisonment. For example, under section 43 of the Civil Aviation Act, an individual found guilty of an offence related to airworthiness can be subject to a fine of up to $165,000 for a corporation, and in the case of individuals, imprisonment for up to five years. It is important to note that the maximum penalties and specific enforcement actions are determined by the severity of the violation and the discretion of the court.
In the specific case of AD/AA-5/16 Amendment 1, CASA has cancelled this AD affecting Gulfstream AA-5A aircraft, as the unsafe condition it was addressing no longer exists. This cancellation, which becomes effective on 13 March 2008, means no replacement AD is required. It is noteworthy that, due to Australia’s obligations under the Convention on International Civil Aviation, no public consultation was conducted regarding this cancellation, and the Office of Best Practice Regulation has determined that such ADs do not require a Regulatory Impact Statement. The AD was issued by the Acting Manager, Systems and New Technologies in the Airworthiness Engineering Branch, on behalf of CASA, in accordance with subsection 84A(2) of the Act.
