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/AC-112/3 affecting all models of Gulfstream (Rockwell) 112 series aeroplanes. CASA has assessed this AD and as a result has cancelled Australian AD/AC-112/3. The cancellation will become effective on 28 August 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 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 comprehensive legal framework for ensuring the safety and efficiency of civil aviation in Australia. This legislation, enacted by the Australian Parliament, aims to facilitate the regulation of civil aviation activities, including the issuance of airworthiness directives to maintain the safety standards of aircraft. The Civil Aviation Safety Regulations 1998 further support the Act by allowing the Civil Aviation Safety Authority (CASA) to issue airworthiness directives for types of aircraft or aeronautical products. These directives are legislative instruments under the Acts Interpretation Act 1901 and the Legislative Instruments Act 2003, ensuring they are subject to parliamentary disallowance if necessary. The Act and its regulations aim to uphold the obligations under the Convention on International Civil Aviation, particularly concerning the continuing airworthiness of aircraft and the dissemination of necessary safety information among contracting states.
Scope and Application
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 provide a comprehensive framework for the regulation of airworthiness in Australia, with a strong focus on safety. Under this framework, the Civil Aviation Safety Authority (CASA) is empowered to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. These directives are critical for ensuring that all aircraft maintain a high standard of airworthiness, in accordance with both national and international standards. The application of these regulations extends to all aircraft registered in Australia and involves a thorough assessment of safety requirements by CASA, Australia's national airworthiness authority. ADs are legislative instruments, subject to disallowance, and their issuance is guided by obligations under international conventions, particularly Annex 8 to the Convention on International Civil Aviation. The responsibility for ensuring the continuing airworthiness of aircraft lies with both the State of Design and the State of Registry, with CASA playing a pivotal role in implementing and enforcing these directives within Australia. The process for issuing and cancelling ADs, such as the recent cancellation of Australian AD/AC-112/3 for Gulfstream (Rockwell) 112 series aeroplanes, is conducted without public consultation as it is based on international obligations and does not necessitate a Regulatory Impact Statement.
Key Provisions
The Civil Aviation Act 1988, through section 98, empowers the Governor-General to make regulations aimed at ensuring the safety of air navigation. This broad authority allows for the creation of specific rules and directives necessary to maintain the safety standards of aircraft and aeronautical products. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 further delineates the powers of the Civil Aviation Safety Authority (CASA), granting it the authority to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. These ADs, as defined under subregulation 39.001(5), 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.
Under the provisions of the Act and the Regulations, CASA is tasked with the responsibility of ensuring the continuing airworthiness of aircraft registered in Australia. This includes the assessment and potential adoption of ADs issued by the State of Design, which is responsible for the overall continuing airworthiness of an aircraft type as per Annex 8 to the Convention on International Civil Aviation. In the case of Gulfstream (Rockwell) 112 series aeroplanes, CASA issued and subsequently cancelled Australian AD/AC-112/3, reflecting a change in the safety requirements for these aircraft. This cancellation, effective from 28 August 2008, was made in accordance with Australia's international obligations and without the need for public consultation or a Regulatory Impact Statement, as determined by the Office of Best Practice Regulation.
The obligations imposed by the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 on CASA include the assessment and potential implementation of ADs from other jurisdictions, as well as the continuous monitoring of aircraft airworthiness. CASA must ensure that all ADs issued are in line with international standards and are necessary to maintain the safety of air navigation. The authority to cancel ADs, as exercised in the case of AD/AC-112/3, is a crucial part of this regulatory framework, allowing for the responsive and flexible management of airworthiness directives in line with evolving safety requirements.
Breach of the obligations under the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 can result in significant penalties and consequences. While the specific penalties for non-compliance are not detailed in the text, general provisions under the Acts Interpretation Act 1901 and the Legislative Instruments Act 2003 suggest that failure to comply with disallowable instruments can lead to legal action, fines, and other civil or criminal penalties. The exact penalties would depend on the nature and severity of the breach, but they underscore the importance of adhering to the airworthiness directives and regulations to maintain the safety of air navigation.
