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.
CASA issued AD/BEECH 56/19 affecting Beechcraft 56 series aeroplanes. CASA has reviewed this AD and as a result has decided to cancel it. The cancellation will become effective on 19 November 2009. No replacement AD is required.
No consultation with the Australian public has taken place on this AD cancellation, because the cancellation results in a reduction of the regulatory burden. 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, New Technology and Regulatory Trends, in the Standards Development and Future Technology Division, on behalf of CASA, in accordance with subsection 84A (2) of the Act.
Overview
The Civil Aviation Act 1988, enacted by the Australian Parliament, governs the regulation of civil aviation in Australia to ensure the safety and efficiency of air navigation. One of the key provisions of this Act is section 98, which empowers the Governor-General to make regulations that align with the Act’s objectives and the interests of air navigation safety. Complementing this Act are the Civil Aviation Safety Regulations 1998, which provide specific regulatory frameworks for maintaining airworthiness, including the issuance of airworthiness directives (ADs) by the Civil Aviation Safety Authority (CASA). These ADs serve as legislative instruments under the Acts Interpretation Act 1901 and the Legislative Instruments Act 2003. The policy objective behind these regulations is to ensure that the continuing airworthiness of aircraft is maintained in accordance with international standards, particularly those outlined in Annex 8 to the Convention on International Civil Aviation. The authority to issue ADs and manage their cancellation, as demonstrated in the case of AD/BEECH 56/19, is vested in CASA, Australia's national airworthiness authority.
Scope and Application
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 apply to the issuance of airworthiness directives (ADs) under regulation 39.001. These regulations empower the Civil Aviation Safety Authority (CASA) to issue ADs for specific types of aircraft or aeronautical products to ensure air navigation safety. Such ADs are considered legislative instruments as per the Acts Interpretation Act 1901 and the Legislative Instruments Act 2003. The application of these regulations extends to all aircraft registered within Australia, imposing responsibilities on the State of Registry to ensure the continuing airworthiness of the aircraft, in line with international standards set by the Convention on International Civil Aviation. CASA, as the national airworthiness authority, is tasked with assessing and implementing ADs issued by the State of Design, ensuring compliance with international and national safety standards. The scope of these regulations is thus broad, affecting aircraft manufacturers, operators, and the aviation industry at large, aiming to maintain high safety standards within Australian airspace and for aircraft registered in Australia.
Key Provisions
The Civil Aviation Act 1988 and its associated Civil Aviation Safety Regulations 1998 provide a comprehensive framework for the regulation of airworthiness in Australia. Under section 98 of the Act, the Governor-General has the authority to create regulations that ensure the safety of air navigation, and regulation 39.001 of the Civil Aviation Safety Regulations 1998 specifically empowers the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for particular types of aircraft or aeronautical products. Such directives are legally binding, as established by subregulation 39.001(5) of the Civil Aviation Safety Regulations 1998, which aligns with the Acts Interpretation Act 1901 and the Legislative Instruments Act 2003. These ADs serve as a crucial mechanism for maintaining the continuing airworthiness of aircraft, in line with the responsibilities outlined in Annex 8 to the Convention on International Civil Aviation.
Entities governed by these regulations, particularly CASA and the States of Design and Registry, have distinct obligations. The State of Design is responsible for the overall continuing airworthiness of an aircraft type, a duty that includes providing essential information to the State of Registry. Conversely, the State of Registry must establish or adopt specific requirements to guarantee the airworthiness of individual aircraft. When CASA, as Australia’s national airworthiness authority, receives an AD from a State of Design concerning a type of aircraft registered in Australia, it is obligated to evaluate the directive and, if necessary, issue a corresponding Australian AD to enforce the requirements stipulated by the State of Design. This collaborative approach ensures that safety standards are uniformly upheld.
The issuance of ADs is a formal process with potential consequences for non-compliance. CASA issued AD/BEECH 56/19, affecting Beechcraft 56 series aeroplanes, but has since decided to cancel this directive, effective from 19 November 2009. This cancellation does not necessitate the issuance of a replacement AD, as it results in a reduction of the regulatory burden. Importantly, the cancellation did not require consultation with the Australian public, a determination made by the Office of Best Practice Regulation, which also concluded that ADs do not require a Regulatory Impact Statement. The directive was made by the Manager, New Technology and Regulatory Trends, in the Standards Development and Future Technology Division, on behalf of CASA, in accordance with subsection 84A(2) of the Act.
Breaches of ADs can lead to significant consequences, both civil and criminal. While the specific civil and criminal penalties for non-compliance are not detailed in the provided text, it is clear that adherence to ADs is mandatory and non-compliance can result in enforcement actions by CASA. These actions may include fines, operational restrictions, or even grounding of the affected aircraft until compliance is achieved. The stringent oversight and enforcement mechanisms underscore the critical importance of maintaining airworthiness standards to ensure the safety of air navigation.
