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 400/72 affecting Cessna 414A 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, Systems and New Technologies, 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 activities in Australia, ensuring safety and efficiency in air navigation. Under this Act, the Civil Aviation Safety Regulations 1998 were introduced to establish comprehensive safety standards for aircraft and aeronautical products. Specifically, regulation 39.001 allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for types of aircraft or aeronautical products. These ADs are legislative instruments subject to disallowance and review, as per the Legislative Instruments Act 2003. The ADs serve to maintain the continuing airworthiness of aircraft types, aligning with international standards set forth in Annex 8 to the Convention on International Civil Aviation, which mandates that the State of Design provides necessary information for ensuring aircraft safety. CASA, as Australia's national airworthiness authority, assesses these international directives and may issue corresponding Australian ADs to enforce compliance within the Australian Register. In this context, CASA issued and subsequently cancelled AD/CESSNA 400/72 for Cessna 414A model aircraft, effective from 25 September 2008, due to the resolution of the unsafe condition identified.
Scope and Application
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 apply to the issuance of airworthiness directives (ADs) by the Civil Aviation Safety Authority (CASA), the national airworthiness authority of Australia. Under section 98 of the Act, the Governor-General can make regulations for the purposes of the Act, and regulation 39.001 of the Regulations allows CASA to issue ADs for kinds of aircraft or aeronautical products. These ADs are legislative instruments under the Legislative Instruments Act 2003 and are subject to disallowance under the Acts Interpretation Act 1901. The ADs are issued in accordance with Annex 8 to the Convention on International Civil Aviation, which places the responsibility of continuing airworthiness on the State of Design and the State of Registry. CASA issues Australian ADs when necessary to mandate the requirements of the State of Design for aircraft on the Australian Register. The issuance, assessment, and cancellation of ADs are managed within CASA, specifically by the Manager, Systems and New Technologies, in the Airworthiness Engineering Branch, as outlined in subsection 84A(2) of the Act. The cancellation of a specific AD, such as AD/CESSNA 400/72 for Cessna 414A model aircraft, is a result of Australia's obligations under the Convention on International Civil Aviation, and such actions do not require public consultation or a Regulatory Impact Statement.
Key Provisions
The main operative sections of the Civil Aviation Safety Regulations 1998 relevant to airworthiness directives (ADs) are regulation 39.001 and its subregulation 39.001(5). Regulation 39.001 empowers the Civil Aviation Safety Authority (CASA) to issue ADs for specific types of aircraft or aeronautical products. These directives are intended to ensure the continuing airworthiness of aircraft, aligning with the overarching responsibility of the State of Design and the requirements set out in Annex 8 to the Convention on International Civil Aviation. Subregulation 39.001(5) further clarifies that an AD is a disallowable instrument under the Acts Interpretation Act 1901 and thus a legislative instrument under the Legislative Instruments Act 2003.
Under these regulations, CASA and other national airworthiness authorities, like the Australian Transport Safety Bureau (ATSB), have specific obligations. They must assess information provided by the State of Design and, if necessary, issue corresponding ADs to ensure compliance with international safety standards. The State of Registry is mandated to ensure the continuing airworthiness of aircraft registered within its jurisdiction, which includes implementing ADs issued by CASA. This regulatory framework ensures that both the State of Design and the State of Registry work in concert to maintain high safety standards in aviation.
Breach of the requirements set out in ADs can have significant consequences. While the Civil Aviation Safety Regulations 1998 do not explicitly detail the penalties for non-compliance with ADs, the overarching Civil Aviation Act 1988 provides for potential enforcement actions. Non-compliance with ADs can result in civil or criminal penalties, depending on the severity of the breach. Civil penalties may include fines, while criminal penalties can result in imprisonment, reflecting the critical importance of adhering to airworthiness directives to ensure the safety of air navigation.
The legislative process for issuing and cancelling ADs, such as AD/CESSNA 400/72 for the Cessna 414A model, involves careful assessment and decision-making by CASA. When CASA determines that an unsafe condition no longer exists, as in the case of the cancelled AD/CESSNA 400/72, it may cancel the AD without further public consultation, given the nature of the legislative instrument and its alignment with international obligations. This process underscores the importance of adhering to international standards and the efficient handling of airworthiness issues to maintain aviation safety.
