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-5/4 affecting Gulfstream AA-5 model aircraft. CASA has assessed this AD and as a result has cancelled AD/AA-5/4. The cancellation will become effective on 4 June 2009. 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 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 framework for the regulation of civil aviation in Australia, focusing on safety and efficiency. One significant aspect of this Act is its delegation of powers to the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) as stipulated under the Civil Aviation Safety Regulations 1998. The Act empowers the Governor-General to make regulations in the interest of air navigation safety, and section 98 specifically authorises such regulations. The ADs, which are legislative instruments, serve as a critical tool for ensuring the continuing airworthiness of aircraft types and aeronautical products, in line with international standards set by the International Civil Aviation Organization (ICAO). CASA, as Australia’s national airworthiness authority, is tasked with assessing information from the State of Design and, where necessary, issuing Australian ADs to mandate compliance with safety requirements. The Act thus addresses the need for a coordinated and internationally compliant approach to maintaining aircraft safety in Australia.
Scope and Application
The Civil Aviation Act 1988, as supplemented by the Civil Aviation Safety Regulations 1998, governs the issuance of airworthiness directives (ADs) within Australia, aiming to ensure the safety of air navigation. This legislation applies to entities such as the Civil Aviation Safety Authority (CASA), aircraft operators, and manufacturers, particularly those involved with aircraft types registered in Australia. The geographic reach of this Act is national, as it pertains to the continuing airworthiness of aircraft registered within Australia and adheres to international standards set by the International Civil Aviation Organization (ICAO). Regulation 39.001 of the Civil Aviation Safety Regulations 1998 specifically empowers CASA to issue ADs for certain kinds of aircraft or aeronautical products, ensuring these meet safety standards. While the Act facilitates the issuance of ADs, subregulation 39.001(5) stipulates that such directives are disallowable instruments under the Acts Interpretation Act 1901. The ADs can also be extended or restricted through subordinate instruments, aligning with Australia’s obligations under international conventions like the Convention on International Civil Aviation.
Key Provisions
The Civil Aviation Safety Regulations 1998, under section 39.001, empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. These ADs serve as legislative instruments, as stipulated by section 46A of the Acts Interpretation Act 1901 and section 6 of the Legislative Instruments Act 2003. Under Annex 8 of the Convention on International Civil Aviation, the State of Design, which is responsible for the continuing airworthiness of an aircraft type, must provide necessary information to the State of Registry to ensure the aircraft's ongoing airworthiness. In the case of Australia, CASA, as the national airworthiness authority, must review the information provided by the State of Design and, if deemed necessary, issue an Australian AD to enforce the requirements.
Entities governed by the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998, such as aircraft manufacturers, operators, and maintenance providers, have specific obligations. They must comply with ADs issued by CASA and ensure the aircraft they operate or maintain meet the continuing airworthiness standards. This includes implementing any required modifications, inspections, or maintenance tasks specified in the ADs to address identified safety issues. Furthermore, these entities must keep records of compliance and ensure that all personnel involved in aircraft operations and maintenance are adequately informed about the ADs and their requirements.
Failure to comply with an AD can result in significant legal consequences. Under the Civil Aviation Act 1988, non-compliance with an AD may be considered an offence, potentially leading to civil or criminal penalties. The maximum penalties for such offences can include fines and imprisonment, depending on the severity of the breach and the discretion of the court. It is crucial for all entities involved in the aviation industry to adhere strictly to the ADs to avoid these serious repercussions and to ensure the safety of air navigation.
