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 310/11 affecting Cessna 310 aircraft. CASA has assessed this AD and as a result has cancelled Australian AD/CESSNA 310/11. The cancellation will become effective on 8 May 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 Acting 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, enacted by the Commonwealth Parliament, addresses the need for comprehensive regulation of civil aviation to ensure the safety of air navigation. This legislation empowers the Governor-General to establish regulations under section 98, thereby allowing the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) as stipulated in regulation 39.001 of the Civil Aviation Safety Regulations 1998. These ADs are legislative instruments that mandate specific actions to maintain the continuing airworthiness of aircraft, aligning with the requirements set forth by the International Civil Aviation Organization (ICAO) under Annex 8. The policy objective is to ensure that aircraft registered in Australia meet international safety standards, thereby safeguarding the public and promoting consistent safety practices across jurisdictions. The Civil Aviation Safety Authority, acting on behalf of CASA, cancelled AD/CESSNA 310/11 for Cessna 310 aircraft, reflecting the resolution of the previously identified unsafe condition and the authority's commitment to maintaining the highest safety standards.
Scope and Application
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 establish the framework for the regulation of airworthiness directives (ADs) in Australia. The Act empowers the Governor-General to make regulations that promote the safety of air navigation, and under these regulations, the Civil Aviation Safety Authority (CASA) can issue ADs for specific types of aircraft or aeronautical products. These ADs, which are legislative instruments, are mandated by the State of Design to ensure the continuing airworthiness of aircraft types, with the State of Registry responsible for implementing these directives to maintain individual aircraft airworthiness. The ADs serve as a critical mechanism under Annex 8 of the Convention on International Civil Aviation, ensuring that all contracting states, including Australia, adhere to international standards of airworthiness. CASA, as Australia’s national airworthiness authority, is obligated to assess and, if necessary, issue Australian ADs to align with those from the State of Design, ensuring compliance with international obligations and domestic safety standards.
Key Provisions
The Civil Aviation Act 1988, in conjunction with the Civil Aviation Safety Regulations 1998, establishes a framework for the issuance of airworthiness directives (ADs). Under section 98 of the Act, the Governor-General can make regulations to ensure the safety of air navigation, and regulation 39.001 of the Regulations allows the Civil Aviation Safety Authority (CASA) to issue ADs for specific types of aircraft or aeronautical products. These ADs serve as legislative instruments, as stipulated in the Legislative Instruments Act 2003. The ADs are crucial for maintaining the continuing airworthiness of aircraft, a responsibility shared between the State of Design and the State of Registry, as outlined in Annex 8 to the Convention on International Civil Aviation.
The obligations imposed by the Act and Regulations on parties and entities primarily revolve around ensuring compliance with ADs. For instance, the State of Design is tasked with providing necessary information to ensure the continuing airworthiness of an aircraft type, while the State of Registry, in this case CASA, must assess and implement ADs issued by the State of Design. This ensures that Australian-registered aircraft meet the safety standards required by international agreements. CASA, acting on behalf of Australia, has the authority to issue, amend, or cancel ADs, as seen in the example of AD/CESSNA 310/11, which was cancelled due to the resolution of the unsafe condition it was intended to address.
The Act and Regulations also outline the consequences of non-compliance with ADs. While the specific offences and penalties are not detailed in the provided text, the general principle is that failing to comply with an AD could result in severe civil or criminal penalties. These might include fines, imprisonment, or other sanctions, depending on the nature and severity of the non-compliance. The regulatory framework is designed to ensure that all stakeholders adhere to the safety requirements established by ADs, thereby safeguarding the integrity of air navigation and the safety of passengers and crew.
In summary, the Civil Aviation Act 1988 and Civil Aviation Safety Regulations 1998 provide a robust mechanism for issuing and enforcing ADs to maintain airworthiness. The obligations on entities such as CASA and the State of Registry are clearly defined, and while specific penalties for non-compliance are not detailed, the potential for severe consequences underscores the importance of adhering to these directives. The cancellation of AD/CESSNA 310/11 exemplifies how ADs are dynamically managed to address evolving safety concerns.
