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/AC/70 affecting Twin Aero Commander 680F, 680F(P), 680FL(P) aircraft models. CASA has assessed this AD and as a result has cancelled Australian AD/AC/70. The cancellation will become effective on 31 July 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, enacted by the Australian Parliament, serves to regulate civil aviation and ensure safety standards are upheld. One of the key mechanisms under this Act is the ability to issue airworthiness directives (ADs) to maintain the safety of air navigation, as per section 98. This was further detailed in the Civil Aviation Safety Regulations 1998, with regulation 39.001 authorising the Civil Aviation Safety Authority (CASA) to issue these directives for specific aircraft types or aeronautical products. The ADs serve as legislative instruments and are crucial for the continuing airworthiness of aircraft, as mandated by Annex 8 of the Convention on International Civil Aviation. In the case of Twin Aero Commander 680F, 680F(P), and 680FL(P) aircraft models, CASA issued an AD that has subsequently been cancelled due to the resolution of the unsafe condition, reflecting Australia’s commitment to international standards and safety.
Scope and Application
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 provide the legislative framework for the regulation of civil aviation in Australia, with a particular focus on ensuring the safety of air navigation. Under section 98 of the Act, the Governor-General has the authority to make regulations that serve the interests of air navigation safety, while 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, which are considered legislative instruments under the Legislative Instruments Act 2003, are a key mechanism for maintaining the continuing airworthiness of aircraft as per international standards set by the Convention on International Civil Aviation. CASA, as Australia’s national airworthiness authority, is responsible for assessing and implementing ADs issued by the States of Design or Registry, thereby ensuring compliance with international obligations and maintaining safety standards.
Key Provisions
The Civil Aviation Act 1988, under section 98, empowers the Governor-General to create regulations that promote the safety of air navigation. This is further operationalised under regulation 39.001 of the Civil Aviation Safety Regulations 1998, where the Civil Aviation Safety Authority (CASA) is authorised to issue airworthiness directives (ADs) for specific kinds of aircraft or aeronautical products. Section 39.001(5) of these regulations clarifies that ADs are disallowable instruments under the Acts Interpretation Act 1901 and thus constitute legislative instruments as per the Legislative Instruments Act 2003.
The obligations imposed by these provisions are significant. The State of Design is responsible for the continuing airworthiness of an aircraft type, mandated by Annex 8 to the Convention on International Civil Aviation. This involves providing all necessary information to ensure the continuing airworthiness of the aircraft type to the States of Registry. For their part, States of Registry must develop or adopt requirements to ensure the continuing airworthiness of individual aircraft within their jurisdiction. When an AD is issued by a State of Design, CASA, as Australia’s national airworthiness authority, must assess this information and, if necessary, issue an Australian AD to enforce the requirements of the State of Design.
Failure to comply with these regulations could result in severe consequences. Although specific penalties are not detailed within the excerpt, non-compliance with ADs could lead to civil or criminal penalties under broader aviation regulations, including potential fines or imprisonment, depending on the severity of the non-compliance. The obligations are clear: States of Design and States of Registry must collaborate to ensure that ADs are issued and followed to maintain airworthiness standards, thereby safeguarding public safety in air navigation.
In summary, the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 establish a robust framework for issuing and enforcing airworthiness directives. These provisions require coordination between States of Design and States of Registry to ensure the continuing airworthiness of aircraft. CASA’s role in assessing and, if necessary, issuing Australian ADs underscores the importance of these regulations in maintaining safety standards. Non-compliance with these directives can lead to serious consequences, highlighting the critical nature of these obligations.
