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/PDH/7 affecting all model PD136/212/1, PD170/212/1 and PD175/212/1 propellers fitted to DH-114 (Herron) aircraft. CASA has assessed this AD and as a result has cancelled Australian AD/PDH/7. The cancellation will become effective on 9 April 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, enacted by the Australian Parliament, was designed to establish a regulatory framework ensuring the safety and efficiency of civil aviation. This Act empowers the Governor-General to create regulations that serve the interests of air navigation safety. A notable regulation under this Act is the Civil Aviation Safety Regulations 1998, which allow 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, critical for maintaining the continuing airworthiness of aircraft and ensuring compliance with international standards as outlined in Annex 8 to the Convention on International Civil Aviation. CASA's role is pivotal in assessing and implementing these directives, ensuring that Australian aircraft meet safety standards set forth by the State of Design and the State of Registry. This legislative framework underscores Australia's commitment to international aviation safety standards and its role in maintaining the safety of aircraft registered within its jurisdiction.
Scope and Application
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 together provide the framework for the regulation of airworthiness directives (ADs) in Australia, with the overarching aim of ensuring the safety of air navigation. Under these legislative instruments, the Civil Aviation Safety Authority (CASA) is empowered to issue ADs concerning types of aircraft or aeronautical products. Such directives are legislative instruments, subject to disallowance and the scrutiny of the Legislative Instruments Act 2003. The application of these ADs extends to all relevant aircraft and aeronautical products registered within Australia, aligning with the responsibilities outlined in Annex 8 to the Convention on International Civil Aviation, where the State of Design must provide necessary information for continuing airworthiness and the State of Registry must ensure the maintenance of airworthiness. CASA, as Australia's national airworthiness authority, is obligated to assess foreign ADs and issue corresponding Australian ADs where necessary. The legislative scope and application are thus comprehensive, covering all aircraft types registered in Australia and ensuring adherence to international safety standards.
Key Provisions
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 outline the framework for the issuance of airworthiness directives (ADs). Section 98 of the Civil Aviation Act 1988 allows the Governor-General to make regulations for the safety of air navigation, and regulation 39.001 of the Civil Aviation Safety Regulations 1998 enables the Civil Aviation Safety Authority (CASA) to issue ADs for specific kinds of aircraft or aeronautical products. Subregulation 39.001(5) clarifies that ADs are legislative instruments, subject to disallowance under the Acts Interpretation Act 1901. This means ADs have legal standing and can be reviewed or annulled by Parliament.
The Act and the Regulations impose specific obligations on CASA and other entities involved in the aviation industry. CASA is required to assess information provided by the State of Design, which is responsible for the continuing airworthiness of an aircraft type, and to issue corresponding ADs as necessary. The State of Registry must also develop or adopt requirements to ensure the continuing airworthiness of individual aircraft. These obligations ensure that aircraft remain safe and airworthy, aligning with the standards set by the Convention on International Civil Aviation.
Breaches of the ADs can lead to serious civil and criminal consequences. Although specific penalties for non-compliance with ADs are not detailed in the provided text, general aviation regulations often include significant fines and potential imprisonment for serious violations. Compliance with ADs is critical to maintaining the safety standards required under the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998. Failure to adhere to these directives can result in severe penalties, underscoring the importance of following the mandated safety procedures.
