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 2008-10-15 affecting Boeing B747 model aircraft. The USA is the State of Design for this type. CASA has assessed this AD and has issued Australian AD/B747/380, which will become effective on 31 July 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, was introduced to regulate civil aviation and ensure the safety of air navigation within Australia. The Act grants the Governor-General the authority to create regulations under section 98, which are aimed at enhancing the safety of air navigation. The Civil Aviation Safety Regulations 1998 further empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products as per regulation 39.001. These ADs serve as legislative instruments, as stated in the Acts Interpretation Act 1901 and the Legislative Instruments Act 2003. The ADs are integral to maintaining the continuing airworthiness of aircraft, a responsibility shared by the State of Design and the State of Registry, as outlined in Annex 8 of the Convention on International Civil Aviation. CASA, acting as Australia's national airworthiness authority, is tasked with assessing information from the State of Design and issuing corresponding Australian ADs when necessary. The ADs are issued under the authority of the Manager, Airframes in the Airworthiness Engineering Branch, on behalf of CASA, in accordance with the Act.
Scope and Application
The Civil Aviation Safety Regulations 1998, under the Civil Aviation Act 1988, empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. These directives are legislative instruments that mandate safety measures to ensure the continuing airworthiness of aircraft registered in Australia. The regulations are rooted in international obligations, specifically Annex 8 of the Convention on International Civil Aviation, which places the responsibility of continuing airworthiness on the State of Design and the State of Registry. In Australia, CASA, as the national airworthiness authority, assesses ADs issued by the State of Design and, if necessary, issues corresponding Australian ADs to enforce these safety requirements. An example of this process is CASA's issuance of AD/B747/380 in response to the US Federal Aviation Administration's AD 2008-10-15 for Boeing B747 model aircraft, reflecting Australia's commitment to international safety standards. These directives do not require public consultation or a Regulatory Impact Statement as they are integral to fulfilling Australia's international obligations under the Convention on International Civil Aviation.
Key Provisions
The Civil Aviation Act 1988, as supplemented by the Civil Aviation Safety Regulations 1998, facilitates the issuance of airworthiness directives (ADs) to ensure the safety of air navigation. Specifically, section 98 of the Act empowers the Governor-General to enact regulations necessary for air navigation safety, while regulation 39.001 of the Regulations permits the Civil Aviation Safety Authority (CASA) to issue ADs for specific types of aircraft or aeronautical products. Furthermore, subregulation 39.001(5) designates ADs as disallowable instruments under section 46A of the Acts Interpretation Act 1901, thus classifying them as legislative instruments in accordance with section 6 of the Legislative Instruments Act 2003.
The obligations imposed by the Act and the Regulations are significant for both the State of Design and the State of Registry of an aircraft. Under Annex 8 to the Convention on International Civil Aviation, the State of Design, which is responsible for the overall continuing airworthiness of an aircraft type, must furnish any necessary information to ensure the continuing airworthiness of the type to the appropriate States of Registry. In turn, the State of Registry is obligated to develop or adopt requirements to maintain the continuing airworthiness of aircraft registered within its jurisdiction. In Australia, CASA, as the national airworthiness authority, must assess ADs issued by the State of Design and, if necessary, issue corresponding Australian ADs to enforce the State of Design's requirements.
Failure to comply with the ADs issued under this framework can result in various civil and criminal consequences. The Act and the Regulations do not explicitly outline the penalties for non-compliance with ADs, but they are subject to broader aviation safety laws, which could include fines or imprisonment for serious breaches. The specific maximum penalties would depend on the nature and severity of the non-compliance and would be determined in accordance with other relevant aviation safety legislation. Moreover, non-compliance with ADs can lead to grounding of the aircraft, which could have severe implications for operators and passengers.
In summary, the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 provide a robust framework for the issuance and enforcement of ADs to maintain the safety and airworthiness of aircraft. These regulations place significant responsibilities on both the State of Design and the State of Registry to ensure compliance, and there are potential civil and criminal consequences for non-compliance, although specific penalties are not detailed in the provided legislative text.
