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/CESSNA 400/80 affecting Cessna 404 model aircraft. CASA has assessed this AD and as a result has cancelled it. The cancellation will become effective on 25 September 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 Branch, on behalf of CASA, in accordance with subsection 84A (2) of the Act.
Overview
The Civil Aviation Act 1988 was enacted to regulate civil aviation in Australia, addressing the need for comprehensive oversight and safety standards to ensure the well-being of passengers and the public. This Act empowers the Governor-General to establish regulations that protect the safety of air navigation, and it serves as the foundation for the Civil Aviation Safety Regulations 1998. Under these regulations, the Civil Aviation Safety Authority (CASA) has the authority to issue airworthiness directives, which are legislative instruments aimed at maintaining and ensuring the safety of aircraft and aeronautical products. The objective of this legislation is to align Australia's civil aviation practices with international standards and to uphold the continuing airworthiness of aircraft registered within the country.
The Civil Aviation Safety Regulations 1998, specifically regulation 39.001, provide CASA with the necessary tools to issue these directives, which are crucial for addressing safety concerns and ensuring compliance with international agreements such as the Convention on International Civil Aviation. The process of issuing and cancelling airworthiness directives is conducted under the authority granted by the Civil Aviation Act 1988, with CASA acting as the national airworthiness authority. The regulatory framework ensures that any unsafe conditions identified are addressed promptly, and the cancellation of directives, such as AD/CESSNA 400/80 for Cessna 404 model aircraft, reflects the resolution of those safety concerns.
Scope and Application
The Civil Aviation Act 1988, along with the Civil Aviation Safety Regulations 1998, governs the issuance of airworthiness directives (ADs) by the Civil Aviation Safety Authority (CASA) for specific kinds of aircraft or aeronautical products. These directives are legislative instruments under the Acts Interpretation Act 1901 and the Legislative Instruments Act 2003. The Act applies to all entities and persons involved in the design, manufacture, registration, and operation of aircraft within Australia, as well as to any aircraft registered in Australia. Geographically, the legislation operates within the national jurisdiction of Australia, in accordance with international obligations under the Convention on International Civil Aviation, particularly Annex 8, which mandates that the State of Design has overall responsibility for the continuing airworthiness of an aircraft type, and the State of Registry is responsible for the airworthiness of individual aircraft. CASA, as Australia’s national airworthiness authority, is required to issue Australian ADs to enforce the requirements of the State of Design when necessary. This particular legislation does not provide for exclusions or exemptions but rather ensures the alignment of Australian regulations with international standards to maintain safety and airworthiness.
Key Provisions
The Civil Aviation Act 1988, particularly section 98, empowers the Governor-General to establish regulations that promote the safety of air navigation, thereby allowing the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) under regulation 39.001 of the Civil Aviation Safety Regulations 1998. These ADs apply to specific types of aircraft or aeronautical products and serve as critical tools for maintaining the continuing airworthiness of aircraft. An AD is a legislative instrument, as stated in subregulation 39.001(5) and further clarified by section 6 of the Legislative Instruments Act 2003.
In line with Annex 8 of the Convention on International Civil Aviation, the State of Design holds primary responsibility for the continuing airworthiness of an aircraft type and must supply necessary information to ensure its safety. This information is typically communicated through ADs, which are issued by most ICAO Contracting States. The State of Registry, which is the country where the aircraft is registered, is also responsible for ensuring the continuing airworthiness of aircraft registered within its jurisdiction. When the State of Design issues an AD for a type of aircraft registered in Australia, CASA must evaluate this information and, if necessary, issue a corresponding Australian AD to enforce the State of Design’s requirements.
The Civil Aviation Safety Authority has issued and subsequently cancelled AD/CESSNA 400/80 for Cessna 404 model aircraft. This cancellation, effective from 25 September 2008, was a direct result of Australia’s obligations under the Convention on International Civil Aviation and the fact that the unsafe condition it addressed no longer exists. Because the cancellation aligns with these international obligations, no consultation with the Australian public was required, and the Office of Best Practice Regulation has determined that no Regulatory Impact Statement was necessary for this AD cancellation. The AD was made by the Manager, Airframes, in the Airworthiness Engineering Branch, on behalf of CASA, in accordance with subsection 84A(2) of the Act.
In terms of compliance, the issuance of ADs by CASA and their subsequent enforcement is crucial for maintaining safety standards within the aviation industry. Failure to comply with these ADs can lead to significant consequences. While specific offences and penalties for non-compliance with ADs are not detailed in the provided text, it is generally understood that such non-compliance can result in civil or criminal penalties, including fines and imprisonment, as stipulated by relevant aviation safety regulations.
