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/FU24/59 affecting Fletcher FU24 model aircraft. CASA has assessed this AD and as a result has cancelled Australian AD/FU24/59. The cancellation will become effective on 7 May 2009. 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 and Structures, 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 Commonwealth Parliament, serves to regulate and oversee the safety aspects of civil aviation in Australia. In alignment with the Act’s objectives and the overarching safety imperatives of air navigation, the Civil Aviation (Airworthiness Directive) Instrument 2009 (F2009L01397) was introduced to manage the issuing of airworthiness directives (ADs). These ADs, which are legislative instruments under the Acts Interpretation Act 1901 and the Legislative Instruments Act 2003, aim to ensure the continuing airworthiness of aircraft types and aeronautical products as mandated by international standards under the Convention on International Civil Aviation. The Civil Aviation Safety Authority (CASA) is responsible for assessing and issuing ADs, reflecting Australia’s commitment to international safety protocols and the specific responsibilities of the State of Registry. The 2009 cancellation of Australian AD/FU24/59 for the Fletcher FU24 model aircraft, without public consultation due to the international obligations under the Convention, exemplifies the practical application of these regulations.
Scope and Application
The Civil Aviation Safety Regulations 1998, under the Civil Aviation Act 1988, establish the framework for issuing airworthiness directives (ADs) which are legal instruments aimed at ensuring the safety and continuing airworthiness of aircraft and aeronautical products within Australia. These ADs apply to specific types of aircraft or aeronautical products and are issued by the Civil Aviation Safety Authority (CASA), Australia’s national airworthiness authority. The application of these regulations extends to all aircraft registered in Australia, encompassing both domestic and international operations conducted within Australian airspace. However, the regulations do not exempt any aircraft from compliance, thus applying uniformly across the board. While the ADs are created under the authority of the Act, they are also subject to disallowance under the Acts Interpretation Act 1901 and are classified as legislative instruments under the Legislative Instruments Act 2003. The issuance and enforcement of ADs are critical in ensuring that the safety standards mandated by the Convention on International Civil Aviation are adhered to, reflecting Australia's obligations as a signatory state.
Key Provisions
The key provisions of the Civil Aviation Safety Regulations 1998, specifically Regulation 39.001, empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific kinds of aircraft or aeronautical products (39.001(1)). An AD is a legislative instrument that can be disallowed under the Acts Interpretation Act 1901 (46A), and it must be assessed and endorsed by the Manager, Airframes and Structures, within CASA’s Airworthiness Engineering Group (84A(2)). In the context of international obligations, Annex 8 to the Convention on International Civil Aviation mandates that the State of Design retains responsibility for the continuing airworthiness of an aircraft type, while the State of Registry must ensure the ongoing airworthiness of individual aircraft registered within its jurisdiction. When a State of Design issues an AD, CASA must review the information and, if deemed necessary, issue a corresponding Australian AD to enforce the requirements stipulated by the State of Design.
The obligations imposed by these regulations on the parties involved are multifaceted. CASA, as Australia’s national airworthiness authority, is tasked with the responsibility of assessing international ADs and deciding whether to issue Australian ADs that mandate compliance with these international directives. This involves a thorough evaluation to determine if the unsafe condition identified in the international AD also affects aircraft registered in Australia. The State of Design must provide comprehensive information to ensure the continuing airworthiness of aircraft types, and the State of Registry must adopt appropriate measures to maintain the airworthiness of individual aircraft. Additionally, the Manager, Airframes and Structures, within CASA’s Airworthiness Engineering Group, is responsible for issuing or cancelling ADs based on the assessment of safety risks.
Failing to comply with the requirements set forth by ADs can result in serious legal consequences. Although the specific offences, penalties, and consequences are not detailed in the provided text, non-compliance with airworthiness directives can typically lead to enforcement actions by CASA. These may include fines, enforcement notices, or other regulatory sanctions. The severity of the penalties often depends on the nature and extent of the non-compliance, and in severe cases, it can result in grounding of the aircraft or even criminal charges if the non-compliance leads to accidents or significant safety risks.
