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 206/96 affecting Bell 206B 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, 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 introduced to ensure the safety of air navigation and to provide a regulatory framework for the civil aviation sector. One of its provisions allows the Governor-General to make regulations for the safety of air navigation, which is further elaborated upon in the Civil Aviation Safety Regulations 1998. The Act was created to address the need for a comprehensive legislative framework governing the safety, efficiency, and regularity of civil aviation within Australia. As part of this framework, the Civil Aviation Safety Authority (CASA) has the authority to issue airworthiness directives (ADs) under regulation 39.001 of the Civil Aviation Safety Regulations 1998. These ADs serve as legislative instruments and are essential for maintaining the continuing airworthiness of aircraft types, aligning with international obligations under the Convention on International Civil Aviation.
Scope and Application
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 together provide the legislative framework for the issuance of airworthiness directives (ADs) in Australia, ensuring that all aircraft meet safety standards. Under the authority granted by section 98 of the Civil Aviation Act 1988, the Governor-General may make regulations for the safety of air navigation, with regulation 39.001 specifically empowering the Civil Aviation Safety Authority (CASA) to issue ADs for specific kinds of aircraft or aeronautical products. These ADs are legislative instruments as per section 46A of the Acts Interpretation Act 1901 and are subject to disallowance under section 6 of the Legislative Instruments Act 2003. The ADs are issued to comply with Australia's obligations under Annex 8 to the Convention on International Civil Aviation, which mandates that the State of Design must provide continuing airworthiness information. CASA, as Australia’s national airworthiness authority, is responsible for assessing this information and issuing Australian ADs as necessary to maintain safety standards. The AD/BELL 206/96 concerning the Bell 206B model aircraft, which has been cancelled by CASA due to the resolution of the unsafe condition, serves as an example of this process.
Key Provisions
The Civil Aviation Act 1988 (section 98) empowers the Governor-General to create regulations that support the Act, particularly concerning the safety of air navigation. The Civil Aviation Safety Regulations 1998 (regulation 39.001) then grant the Civil Aviation Safety Authority (CASA) the authority to issue airworthiness directives (ADs) for certain types of aircraft or aeronautical products. These ADs are considered disallowable instruments under section 46A of the Acts Interpretation Act 1901 and are classified as legislative instruments in accordance with section 6 of the Legislative Instruments Act 2003.
The ADs are integral to maintaining the continuing airworthiness of aircraft, a responsibility that falls to the State of Design and the State of Registry as per Annex 8 to the Convention on International Civil Aviation. CASA, as Australia’s national airworthiness authority, plays a crucial role in this process by assessing information from the State of Design and, if necessary, issuing Australian ADs that enforce the requirements of the State of Design. This ensures that Australian aircraft meet international safety standards.
Under the Civil Aviation Safety Regulations 1998, CASA issued AD/BELL 206/96 for Bell 206B model aircraft. However, CASA has subsequently assessed this directive and decided to cancel it, effective from 23 October 2008. This cancellation is due to the unsafe condition no longer existing, and no replacement AD is required. It is important to note that, as a result of Australia’s commitments under the Convention on International Civil Aviation, there was no public consultation regarding the AD cancellation, and the Office of Best Practice Regulation has determined that ADs do not necessitate a Regulatory Impact Statement.
The AD cancellation was 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 Civil Aviation Act 1988. This process ensures that all regulatory actions taken are consistent with the legislative framework and international obligations.
Breaches of the regulations or non-compliance with the ADs can lead to serious consequences. Under the Civil Aviation Act 1988, non-compliance with ADs can result in substantial penalties. These penalties can include fines and imprisonment, with the maximum fines reaching up to $500,000 for corporations and $100,000 for individuals, depending on the severity and nature of the breach. Additionally, CASA can take enforcement actions such as grounding aircraft or imposing operational restrictions to ensure compliance and safety.
