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/AC/71 affecting Twin Aero Commander 690B model aircraft. CASA has assessed this AD and as a result has cancelled Australian AD/AC/71. The cancellation will become effective on 31 July 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, Airframe and Structures, in the Airworthiness Engineering Branch, 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, with a primary focus on ensuring the safety of air navigation. This Act empowers the Governor-General to make regulations that serve the interests of aviation safety, delegating authority to the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. These directives are critical for maintaining the continuing airworthiness of aircraft, in line with international standards set by the International Civil Aviation Organization (ICAO). CASA, as Australia's national airworthiness authority, plays a pivotal role in assessing international ADs issued by the State of Design and, when necessary, issuing corresponding Australian ADs to ensure compliance with safety standards. The process is designed to uphold Australia's obligations under the Convention on International Civil Aviation, ensuring that all aircraft registered in Australia meet the necessary safety requirements.
Scope and Application
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 govern the issuance of airworthiness directives (ADs) in Australia, ensuring the continuing airworthiness of aircraft and aeronautical products. Under these regulations, CASA, as the national airworthiness authority, is empowered to issue ADs for kinds of aircraft or aeronautical products in accordance with the interests of air navigation safety. The ADs are considered legislative instruments and are issued in line with international obligations, such as Annex 8 to the Convention on International Civil Aviation, which outlines the responsibilities of the State of Design and the State of Registry in ensuring airworthiness. The ADs apply to the specific aircraft types or products registered in Australia, and the State of Registry is responsible for enforcing compliance with the issued directives. In the case of the Twin Aero Commander 690B model aircraft, CASA assessed and subsequently cancelled the AD/AC/71 due to the resolution of the unsafe condition, reflecting Australia's adherence to international obligations without the need for public consultation or a Regulatory Impact Statement. The AD cancellation was executed by the Manager, Airframe and Structures, in the Airworthiness Engineering Branch on behalf of CASA, in compliance with the Act.
Key Provisions
The Civil Aviation Act 1988 (section 98) empowers the Governor-General to make regulations that support the Act, particularly focusing on the safety of air navigation. Under the Civil Aviation Safety Regulations 1998 (regulation 39.001), the Civil Aviation Safety Authority (CASA) is authorised to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. These directives serve as essential tools in maintaining the safety standards of aircraft in the Australian airspace. Additionally, subregulation 39.001(5) states that an AD is a disallowable instrument under section 46A of the Acts Interpretation Act 1901, which means it can be subject to disallowance by either house of the Parliament. Furthermore, according to the Legislative Instruments Act 2003 (section 6), an AD is considered a legislative instrument, giving it formal legal status.
The obligations placed on parties and entities governed by these regulations are significant. The State of Design has a primary responsibility under Annex 8 of the Convention on International Civil Aviation to ensure the continuing airworthiness of an aircraft type. This includes providing necessary information to the States of Registry, which are responsible for the airworthiness of individual aircraft registered within their jurisdictions. CASA, as Australia’s national airworthiness authority, must evaluate any ADs issued by the State of Design and, if deemed necessary, issue corresponding Australian ADs to enforce the required safety measures. The recent cancellation of AD/AC/71 for Twin Aero Commander 690B model aircraft is an example of CASA exercising its authority to ensure that Australian aviation safety standards are maintained.
Failure to comply with airworthiness directives can lead to serious consequences. The Civil Aviation Act 1988 and the associated regulations establish various offences and penalties for non-compliance. While the specific penalties are not detailed in the provided text, it is clear that non-compliance with ADs can result in both civil and criminal liabilities. Such penalties may include fines and, in more severe cases, imprisonment. The severity of the penalty often depends on the nature and extent of the non-compliance, with the potential for significant repercussions for both individuals and organisations that fail to adhere to the mandated safety standards.
In summary, the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 provide a robust framework for ensuring the safety and airworthiness of aircraft in Australia. The issuance and enforcement of airworthiness directives are central to this framework, with CASA playing a critical role in assessing and implementing these directives. The obligations on States of Design and States of Registry, as well as the potential penalties for non-compliance, underscore the importance of adhering to these regulations. The recent cancellation of AD/AC/71 for Twin Aero Commander 690B model aircraft exemplifies the dynamic nature of these regulations and the commitment to maintaining the highest safety standards in Australian aviation.
