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 206/35 affecting Cessna U206 model aeroplanes. CASA has assessed this AD and as a result has cancelled Australian AD/CESSNA 206/35. 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 Systems and New Technologies, 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, provides the framework for regulating civil aviation in Australia, with a primary focus on ensuring the safety of air navigation. The Act empowers the Governor-General to issue regulations, including those that govern the issuance of airworthiness directives (ADs), as per section 98. These ADs, which are considered legislative instruments under the Legislative Instruments Act 2003, are intended to mandate safety requirements for specific types of aircraft or aeronautical products. The Civil Aviation Safety Regulations 1998 further specify the process through which the Civil Aviation Safety Authority (CASA) can issue ADs to address identified safety issues. The policy objective of this legislative framework is to ensure that aircraft in Australian airspace maintain their airworthiness in accordance with international standards, thereby enhancing aviation safety.
Scope and Application
The Civil Aviation Act 1988, as supplemented by the Civil Aviation Safety Regulations 1998, applies to entities and individuals involved in civil aviation within Australia, including aircraft manufacturers, operators, maintenance providers, and other aviation stakeholders. Under this legislative framework, the Civil Aviation Safety Authority (CASA) is empowered to issue airworthiness directives (ADs) to ensure the safety of air navigation. These ADs apply to specific types of aircraft or aeronautical products and are issued to address safety concerns or rectify unsafe conditions identified in the design or operation of aircraft. The authority to issue ADs is exercised through regulation 39.001 of the Civil Aviation Safety Regulations 1998, and any such directive is a legislative instrument as per the Acts Interpretation Act 1901 and the Legislative Instruments Act 2003. Furthermore, the ADs issued by CASA are influenced by the obligations Australia has under the Convention on International Civil Aviation, particularly in relation to the responsibilities of the State of Design and the State of Registry concerning the continuing airworthiness of aircraft. In the specific case of AD/CESSNA 206/35, which affected Cessna U206 model aeroplanes, CASA has determined that the unsafe condition no longer exists, leading to the cancellation of this AD, effective from 25 September 2008.
Key Provisions
The Civil Aviation Act 1988, as referenced in section 98, empowers the Governor-General to establish regulations for the safety of air navigation. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 specifically allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for particular types of aircraft or aeronautical products. According to subregulation 39.001(5), these ADs are classified as disallowable instruments under section 46A of the Acts Interpretation Act 1901, and thus fall under the purview of the Legislative Instruments Act 2003. This regulatory framework ensures that ADs are issued in accordance with international standards, particularly those outlined in Annex 8 to the Convention on International Civil Aviation, which assigns the State of Design the overarching responsibility for the continuing airworthiness of an aircraft type, requiring them to provide necessary information to the States of Registry.
In terms of obligations, the State of Design is mandated to furnish any information essential to ensure the continuing airworthiness of the aircraft type to the States of Registry. The State of Registry, in turn, is responsible for the continuing airworthiness of individual aircraft and must establish or adopt requirements to maintain this airworthiness. When a State of Design issues an AD concerning an aircraft type on the Australian Register, CASA, as Australia's national airworthiness authority, is obligated to evaluate this information and, if deemed appropriate, issue an Australian AD to enforce the State of Design's requirements. This systematic approach ensures that safety standards are uniformly upheld across different jurisdictions.
Any breach of the provisions outlined in the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 can lead to serious legal consequences. While specific penalties for non-compliance with ADs are not detailed in the provided text, general contraventions under civil aviation law can result in substantial fines and, in severe cases, imprisonment. For instance, under the Crimes Act 1914, an individual found guilty of endangering the safety of an aircraft could face penalties including fines of up to $210,000 and imprisonment for up to 10 years. Additionally, CASA can impose administrative penalties for non-compliance with airworthiness directives, further emphasising the importance of adhering to these regulations.
In summary, the Civil Aviation Act 1988 and the associated regulations mandate a robust framework for the issuance and enforcement of airworthiness directives to ensure the safety of air navigation. The roles and responsibilities of the State of Design and the State of Registry are clearly delineated, with CASA acting as the central authority in Australia. Non-compliance with these regulations can lead to severe civil and criminal penalties, underscoring the critical nature of adhering to these safety measures.
