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/BEECH 55/55 affecting Beechcraft 58P and 58PA model aircraft. CASA has assessed this AD and as a result has cancelled Australian AD/BEECH 55/55. The cancellation will become effective on 5 June 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, 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 was enacted to provide for the regulation of civil aviation in Australia, addressing the need for comprehensive safety and operational standards within the industry. Under section 98, the Governor-General is empowered to create regulations that promote the safety of air navigation, delegating authority to 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 serve as legislative instruments, playing a crucial role in ensuring the continuing airworthiness of aircraft as mandated by Annex 8 to the Convention on International Civil Aviation. CASA’s role involves assessing directives issued by the State of Design and, where necessary, issuing corresponding Australian ADs to enforce the required safety measures. The Act thus facilitates the alignment of Australian aviation safety standards with international obligations, ensuring the safety and efficiency of civil aviation operations within the country.
Scope and Application
The Civil Aviation Safety Regulations 1998, under the authority of the Civil Aviation Act 1988, empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) that pertain to specific types of aircraft or aeronautical products. These directives are essential tools for ensuring the continuing airworthiness of aircraft, as mandated by Annex 8 to the Convention on International Civil Aviation. ADs are issued by CASA in response to safety concerns identified by the State of Design or other ICAO Contracting States. The geographic scope of these regulations is national, with CASA acting as Australia’s regulatory authority to enforce airworthiness standards. The application of these directives is inclusive of all aircraft and aeronautical products registered within Australia, thus affecting entities such as aircraft manufacturers, operators, and maintenance service providers. The ADs are legislative instruments, subject to disallowance under the Acts Interpretation Act 1901, and the cancellation or amendment of such directives can occur without public consultation due to their technical nature and the international obligations under the Convention on International Civil Aviation.
Key Provisions
The Civil Aviation Act 1988 (section 98) empowers the Governor-General to enact regulations aimed at ensuring the safety of air navigation. One such regulation, regulation 39.001 of the Civil Aviation Safety Regulations 1998, allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. These ADs serve as a legislative instrument, as outlined in section 46A of the Acts Interpretation Act 1901 and confirmed by section 6 of the Legislative Instruments Act 2003. They are a critical tool for maintaining the continuing airworthiness of aircraft, a responsibility that lies with the State of Design and the State of Registry under Annex 8 of the Convention on International Civil Aviation.
When CASA issues an AD, it mandates specific requirements to address identified safety concerns. The State of Design, which holds overall responsibility for the continuing airworthiness of an aircraft type, provides necessary information to ensure compliance. The State of Registry must then develop or adopt corresponding requirements to maintain the airworthiness of individual aircraft. For example, in the case of Beechcraft 58P and 58PA model aircraft, CASA issued AD/BEECH 55/55, which has since been cancelled due to the resolution of the unsafe condition it addressed. The cancellation of this AD, effective from 5 June 2008, was made under the authority of subsection 84A(2) of the Civil Aviation Act 1988 by the Manager, Systems and New Technologies in the Airworthiness Engineering Branch of CASA.
The obligations imposed by these regulations are clear and specific. CASA must assess any ADs issued by the State of Design and determine whether an Australian AD is necessary. In the case of Beechcraft 58P and 58PA, CASA's assessment led to the cancellation of the AD/BEECH 55/55, reflecting that the unsafe condition no longer exists. The process of issuing and cancelling ADs is transparent and adheres to the obligations under the Convention on International Civil Aviation. However, due to the nature of these legislative instruments, no public consultation was conducted on the cancellation of this AD, and the Office of Best Practice Regulation determined that a Regulatory Impact Statement was not required.
In terms of consequences, the Civil Aviation Safety Regulations 1998 and the Civil Aviation Act 1988 provide for various offences and penalties for non-compliance with ADs. The specifics of these penalties are not detailed in the explanatory statement, but generally, non-compliance with ADs can lead to significant civil or criminal penalties. Such penalties may include fines or imprisonment, depending on the severity of the violation. These measures underscore the importance of adhering to airworthiness directives to maintain the safety of air navigation.
