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/BELL 206/11 affecting Bell 206A model aircraft. CASA has assessed this AD and as a result has cancelled it. The cancellation will become effective on 23 October 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, Airframes 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 comprehensive framework for the regulation of civil aviation in Australia, ensuring safety, efficiency, and environmental considerations. Under the authority of this Act, the Governor-General has the power to make regulations for the safety of air navigation, as evidenced by the Civil Aviation Safety Regulations 1998. The Civil Aviation Safety Regulations 1998, particularly regulation 39.001, empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) concerning types of aircraft or aeronautical products. These directives are critical for maintaining the continuing airworthiness of aircraft and are subject to disallowance under section 46A of the Acts Interpretation Act 1901, classifying them as legislative instruments. The ADs issued by CASA comply with international standards set out in Annex 8 to the Convention on International Civil Aviation, which outlines the responsibilities of the State of Design and State of Registry regarding aircraft airworthiness. The Civil Aviation Safety Authority has the duty to assess and, if necessary, issue ADs to ensure compliance with these international standards and domestic safety requirements.
Scope and Application
The Civil Aviation Act 1988, along with the Civil Aviation Safety Regulations 1998, provides the legislative framework for ensuring the safety of air navigation in Australia. Under this legislation, the Civil Aviation Safety Authority (CASA) is empowered to issue airworthiness directives (ADs) which are regulatory instruments aimed at maintaining the airworthiness of aircraft and aeronautical products. These directives are applicable to all aircraft registered in Australia, irrespective of the aircraft type or the operator. Geographically, the application of these regulations spans across the Commonwealth of Australia, ensuring uniform safety standards are met nationwide. Subregulation 39.001(5) of the Civil Aviation Safety Regulations 1998 further clarifies that ADs are disallowable instruments under the Acts Interpretation Act 1901 and, as such, are considered legislative instruments. The issuance of these directives is a critical component of Australia’s adherence to international obligations under the Convention on International Civil Aviation, particularly with respect to the responsibilities of the State of Design and the State of Registry in ensuring continuing airworthiness. The legislative framework allows for the cancellation of ADs, as demonstrated by the recent cancellation of AD/BELL 206/11 for Bell 206A model aircraft, which will become effective on 23 October 2008, reflecting that the previously identified unsafe condition no longer exists.
Key Provisions
The Civil Aviation Act 1988, in particular section 98, empowers the Governor-General to enact regulations aimed at ensuring the safety of air navigation. Under this provision, the Civil Aviation Safety Regulations 1998, specifically regulation 39.001, allow the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. An AD, as outlined in subregulation 39.001(5), is considered a disallowable instrument under section 46A of the Acts Interpretation Act 1901 and is thus classified as a legislative instrument in accordance with section 6 of the Legislative Instruments Act 2003. This legislative framework is designed to ensure that aircraft remain airworthy and safe for operation.
The obligations imposed by the Civil Aviation Safety Regulations 1998, particularly those concerning ADs, require CASA to act when a State of Design issues an AD against a type of aircraft registered in Australia. CASA must evaluate the AD and, if deemed necessary, issue an Australian AD to enforce the requirements set by the State of Design. This process is crucial for maintaining the continuing airworthiness of aircraft registered in Australia, aligning with Annex 8 to the Convention on International Civil Aviation, which stipulates that the State of Design holds the overarching responsibility for the airworthiness of an aircraft type, while the State of Registry ensures the airworthiness of individual aircraft.
The Civil Aviation Safety Authority has issued AD/BELL 206/11 concerning Bell 206A model aircraft, which has subsequently been assessed and cancelled by CASA. This cancellation, effective from 23 October 2008, signifies that the unsafe condition previously identified no longer exists, hence no replacement AD is necessary. This action aligns with Australia’s obligations under the Convention on International Civil Aviation and was undertaken without public consultation as determined by the Office of Best Practice Regulation, which found that ADs do not require a Regulatory Impact Statement. The AD was issued by the Manager, Airframes, in the Airworthiness Engineering Group, on behalf of CASA, in accordance with subsection 84A(2) of the Act.
In terms of compliance and enforcement, any breach of the obligations under the Civil Aviation Safety Regulations 1998, particularly those related to ADs, may lead to civil or criminal penalties. While specific penalties are not detailed in the provided text, they generally include fines and potential imprisonment for serious violations, reflecting the critical nature of air safety regulations. The authority to issue and enforce ADs is pivotal in maintaining the safety standards required by international conventions and domestic legislation, ensuring that aircraft remain in a safe and airworthy condition.
