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 500/11 affecting Cessna 500 model aeroplanes. CASA has assessed this AD and as a result has cancelled Australian AD/CESSNA 500/11. 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, Airframe 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 was enacted to establish and regulate civil aviation activities in Australia, ensuring safety and efficiency in the sector. This legislation empowers the Governor-General to make regulations under section 98, aimed at enhancing air navigation safety. The Civil Aviation Safety Regulations 1998 further detail these regulations, allowing the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products as outlined in regulation 39.001. These ADs serve as legislative instruments under the Acts Interpretation Act 1901 and are essential for maintaining the continuing airworthiness of aircraft, in alignment with international standards set by the International Civil Aviation Organization (ICAO). The Civil Aviation Act 1988 and its associated regulations thus address the need for stringent safety measures and regulatory oversight in civil aviation, ensuring that Australia meets its obligations under international conventions while safeguarding public safety.
Scope and Application
The Civil Aviation Act 1988, as supplemented by the Civil Aviation Safety Regulations 1998, establishes the framework within which the Civil Aviation Safety Authority (CASA) can issue airworthiness directives (ADs). These regulations empower CASA to issue ADs for specific kinds of aircraft or aeronautical products, thereby ensuring adherence to safety standards across the industry. Such directives are integral to the ongoing maintenance of airworthiness and are issued by most states that are party to the Convention on International Civil Aviation. The State of Design, which is responsible for the initial airworthiness of an aircraft type, must provide necessary information to ensure continued safety. The State of Registry, on the other hand, is tasked with implementing these directives to maintain the airworthiness of individual aircraft registered within its jurisdiction. In Australia, CASA functions as the national airworthiness authority and must assess ADs issued by the State of Design, issuing corresponding Australian ADs when necessary. The issuance, amendment, or cancellation of ADs is a legislative instrument, subject to the provisions of the Legislative Instruments Act 2003. The cancellation of Australian AD/CESSNA 500/11 affecting Cessna 500 model aeroplanes is a recent example, reflecting Australia's compliance with international obligations and the cessation of an unsafe condition.
Key Provisions
The Civil Aviation Act 1988, along with the Civil Aviation Safety Regulations 1998, provides the legislative framework for ensuring the safety of air navigation in Australia. Section 98 of the Act allows the Governor-General to make regulations for the safety of air navigation. Regulation 39.001 specifically empowers the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products, establishing these ADs as legislative instruments under the Acts Interpretation Act 1901. This regulatory mechanism is crucial for maintaining the continuing airworthiness of aircraft types, as outlined under Annex 8 to the Convention on International Civil Aviation. The State of Design is responsible for providing necessary information to ensure airworthiness, while the State of Registry must implement requirements to maintain this airworthiness. When CASA issues an AD, it mandates the compliance with airworthiness requirements established by the State of Design.
The obligations imposed by the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 on the parties involved are significant. CASA, as the national airworthiness authority, must assess and implement ADs issued by the State of Design for aircraft registered in Australia. The State of Registry is obligated to ensure that each aircraft under its jurisdiction meets continuing airworthiness standards. This includes developing or adopting necessary requirements and complying with ADs to address safety issues identified by the State of Design. The State of Design, on the other hand, is responsible for issuing ADs and providing relevant information to ensure the safety and airworthiness of the aircraft type it designs. These obligations ensure that all stakeholders work collaboratively to maintain high safety standards in civil aviation.
Breaching the requirements set forth in the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 can result in serious consequences. While the specific penalties for non-compliance are not detailed in the provided text, it is clear that failure to adhere to ADs and other regulatory requirements can lead to safety risks and potential legal repercussions. Non-compliance can result in civil penalties, such as fines, or even criminal charges, depending on the severity of the breach. The text mentions that the AD in question was cancelled due to Australia’s obligations under the Convention on International Civil Aviation, indicating a framework where adherence to international standards is paramount. The specific maximum penalties for violations are not stated but can be substantial, reflecting the critical nature of air safety regulations.
