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/AT/8 amendment 1 affecting Airtractor AT 300, 400 and 500 model aeroplanes. CASA has assessed this AD and as a result has cancelled Australian AD/AT/8 amendment 1. The cancellation will become effective on 7 May 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 establish and maintain a safe and efficient civil aviation system in Australia. One of its key provisions allows the Governor-General to make regulations for the purposes of the Act, with a primary focus on ensuring the safety of air navigation. The Civil Aviation Safety Regulations 1998 further elaborate on these provisions, specifically empowering the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. These directives, which are legislative instruments, are crucial for maintaining the continuing airworthiness of aircraft, in line with international standards set by the Convention on International Civil Aviation. CASA, as Australia’s national airworthiness authority, is responsible for assessing and issuing ADs when necessary, thereby fulfilling the obligations of both the State of Design and the State of Registry under international conventions.
Scope and Application
The Civil Aviation Act 1988, along with the Civil Aviation Safety Regulations 1998, provides the legislative framework under which the Civil Aviation Safety Authority (CASA) issues airworthiness directives (ADs). These regulations apply to the continuing airworthiness of aircraft registered in Australia, ensuring that the safety standards set by the State of Design and the State of Registry are met. The Act and its associated regulations pertain to all entities involved in civil aviation, including aircraft manufacturers, operators, and maintenance providers, as well as individuals such as pilots and air traffic controllers. The scope of the ADs extends to any kind of aircraft or aeronautical products, ensuring comprehensive coverage of all aspects of airworthiness. Geographically, the application of these regulations is national, as CASA acts as Australia's authority under the Convention on International Civil Aviation, ensuring compliance with international standards. Any exclusions or exemptions from these regulations are detailed in the subordinate instruments issued by CASA, which may vary depending on specific circumstances or types of aircraft. Additionally, while ADs are considered legislative instruments under the Legislative Instruments Act 2003, the process of issuing and cancelling them, as seen in the case of AD/AT/8 amendment 1, is subject to rigorous assessment and does not typically involve public consultation or a Regulatory Impact Statement.
Key Provisions
The key operative sections of the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 provide a framework for the issuance of airworthiness directives (ADs). Specifically, section 98 of the Civil Aviation Act 1988 allows the Governor-General to make regulations for the safety of air navigation. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 empowers the Civil Aviation Safety Authority (CASA) to issue ADs for certain types of aircraft or aeronautical products. These ADs are legislative instruments, as per section 6 of the Legislative Instruments Act 2003. Such directives are crucial for maintaining the airworthiness of aircraft and ensuring compliance with international standards set by the Convention on International Civil Aviation.
The obligations imposed by these regulations require the State of Design to provide necessary information to ensure the continuing airworthiness of an aircraft type, which the State of Registry must then adopt or develop to meet its own airworthiness requirements. In Australia, CASA is the national airworthiness authority responsible for assessing information from the State of Design and, if necessary, issuing an Australian AD to mandate the requirements of the State of Design. This ensures that Australian-registered aircraft meet international safety standards.
Failure to comply with an AD can lead to significant consequences. Under section 109 of the Civil Aviation Act 1988, non-compliance with an airworthiness directive is an offence, and CASA has the authority to take enforcement action against individuals or entities that fail to comply. Such actions may include fines, suspension or revocation of aircraft registration, or even criminal charges for more serious breaches. The maximum penalties for these offences can vary, but they are designed to ensure that safety regulations are strictly adhered to, thereby protecting the public and maintaining the integrity of the aviation industry.
In summary, the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 provide a comprehensive framework for the issuance and enforcement of airworthiness directives. These regulations mandate that CASA issue and enforce ADs to ensure the safety and airworthiness of aircraft registered in Australia. Non-compliance with these directives can result in severe penalties, reinforcing the importance of adhering to these safety standards.
