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 US FAA has issued AD 2008-08-23 affecting Boeing B737 model aircraft. The USA is the State of Design for this type. CASA has assessed this AD and has issued Australian AD/B737/325, which will become effective on 5 June 2008.
As this AD is issued because of Australia’s obligations under Convention on International Civil Aviation, and because it is issued in response to an AD raised by the relevant State of Design, no consultation of the Australian public has taken place on this AD. 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 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 Australian Parliament, serves to regulate the safety of air navigation, ensuring the national and international standards of aviation safety are upheld. This legislation empowers the Governor-General to create regulations in the interest of air navigation safety, with the Civil Aviation Safety Regulations 1998 providing a framework for such regulations. Specifically, regulation 39.001 allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for certain types of aircraft or aeronautical products. These ADs are critical in maintaining the continuing airworthiness of aircraft, as mandated by international standards set forth in Annex 8 to the Convention on International Civil Aviation. The ADs are designed to address safety issues and are issued by the State of Design, with CASA responsible for ensuring these directives are appropriately implemented within Australia, thereby fulfilling the country's international obligations and maintaining safety standards.
Scope and Application
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998, as amended, provide the legislative framework under which airworthiness directives (ADs) are issued in Australia. Under section 98 of the Civil Aviation Act 1988, the Governor-General has the authority to enact regulations to ensure the safety of air navigation. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 empowers the Civil Aviation Safety Authority (CASA) to issue ADs for specific types of aircraft or aeronautical products. The issuance of these ADs is underpinned by international obligations, particularly those outlined in Annex 8 to the Convention on International Civil Aviation, which designates the State of Design with overall responsibility for the continuing airworthiness of an aircraft type. CASA, as Australia’s national airworthiness authority, is tasked with assessing information from the State of Design and issuing corresponding Australian ADs to enforce the necessary requirements. This process ensures that Australian aircraft meet international safety standards, and the ADs become legislative instruments under the Legislative Instruments Act 2003. The scope of the ADs applies to all aircraft registered in Australia and their operators, ensuring compliance with safety mandates issued both domestically and internationally.
Key Provisions
The Civil Aviation Act 1988 (section 98) empowers the Governor-General to make regulations that support the Act's objectives, particularly focusing on the safety of air navigation. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 grants the Civil Aviation Safety Authority (CASA) the authority to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. These ADs serve as legislative instruments under section 46A of the Acts Interpretation Act 1901 and are detailed further in subregulation 39.001(5) of the Civil Aviation Safety Regulations 1998. Such directives are pivotal for maintaining the continuing airworthiness of aircraft types and ensuring compliance with international standards set by the International Civil Aviation Organization (ICAO) under Annex 8 to the Convention on International Civil Aviation.
The obligations imposed by the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 necessitate that the State of Design, which is responsible for the design of the aircraft, provide all necessary information to the States of Registry to ensure the continuing airworthiness of aircraft types. For Australia, this means that CASA, as the national airworthiness authority, must assess any ADs issued by the State of Design and, if necessary, issue corresponding Australian ADs. This ensures that the regulatory requirements are effectively communicated and implemented within Australia. Furthermore, the State of Registry, in this case, CASA, must develop or adopt specific requirements to maintain the airworthiness of individual aircraft registered in Australia, ensuring they meet the safety standards set by ICAO.
The legal framework under the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 includes provisions for penalties and consequences for non-compliance with airworthiness directives. Failure to comply with these directives can result in serious safety risks, and regulatory authorities have the power to enforce compliance through various means, including fines and other sanctions. While the specific penalties are not detailed in the provided text, it is understood that non-compliance can lead to civil or criminal penalties depending on the severity of the breach and the impact on safety. CASA has the authority to take enforcement action against entities or individuals who fail to comply with the mandated requirements set forth in airworthiness directives.
In summary, the key provisions of the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 provide a structured framework for issuing and enforcing airworthiness directives. These directives are essential for maintaining the safety and airworthiness of aircraft within Australia and ensuring compliance with international standards. CASA’s role in assessing and issuing ADs, along with the obligations placed on States of Design and States of Registry, highlights the collaborative approach needed to uphold aviation safety standards. The absence of public consultation and a Regulatory Impact Statement for these directives underscores their critical nature and the importance of international coordination in aviation safety regulation.
