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 36/19 affecting Beechcraft models 36 series aircraft fitted with certain internally lighted altimeters. CASA has assessed this AD and as a result has cancelled Australian AD/BEECH 36/19. The cancellation will become effective on 8 May 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 Acting 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, with a strong emphasis on ensuring the safety of air navigation. The Act empowers the Governor-General to create regulations that serve the interests of aviation safety, as detailed under section 98. Pursuant to this authority, the Civil Aviation Safety Regulations 1998 were established, which include provisions for the issuance of airworthiness directives (ADs) by the Civil Aviation Safety Authority (CASA) to ensure the continuing airworthiness of aircraft and aeronautical products. This legislative framework is designed to comply with international standards set by the Convention on International Civil Aviation, particularly through Annex 8, which outlines the responsibilities of States of Design and States of Registry in maintaining aircraft airworthiness. The Act and its regulations aim to harmonise Australia's approach to air safety with global practices, ensuring that domestic aviation remains safe and compliant with international obligations.
Scope and Application
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 outline the framework for the issuance of airworthiness directives (ADs) in Australia, ensuring the safety of air navigation and the continuing airworthiness of aircraft. The Act applies to the Civil Aviation Safety Authority (CASA), which is responsible for issuing ADs for specific types of aircraft or aeronautical products under regulation 39.001. These directives are legislative instruments that must comply with the Acts Interpretation Act 1901 and the Legislative Instruments Act 2003. The scope of the ADs extends to aircraft registered in Australia, with the State of Design having overall responsibility for the continuing airworthiness of an aircraft type, and the State of Registry ensuring compliance with relevant airworthiness requirements. The application of ADs is influenced by international obligations under the Convention on International Civil Aviation, specifically Annex 8, which mandates that the State of Design must provide necessary information to ensure the continuing airworthiness of a type to the appropriate States of Registry. This international cooperation ensures that ADs issued by one country are considered by others, maintaining a uniform standard of safety across the global aviation industry.
Key Provisions
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 provide a framework for ensuring the safety of air navigation. Specifically, section 98 of the Act empowers the Governor-General to make regulations in the interest of safety, while regulation 39.001 of the Regulations allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for types of aircraft or aeronautical products. This regulatory power is exercised under the authority of the State of Design, which has a responsibility under Annex 8 of the Convention on International Civil Aviation to ensure the continuing airworthiness of aircraft types and provide necessary information to States of Registry. The State of Registry, in turn, is tasked with ensuring the airworthiness of individual aircraft.
In practice, when CASA issues an AD in response to a directive from the State of Design, it mandates specific requirements for maintaining the airworthiness of certain aircraft types. For instance, AD/BEECH 36/19, which affected Beechcraft models 36 series aircraft fitted with certain internally lighted altimeters, was issued by CASA. Following an assessment, CASA cancelled this AD because the unsafe condition it addressed no longer existed. This cancellation reflects CASA's role in ensuring that airworthiness directives are both necessary and effective in maintaining safety standards. Notably, because the cancellation was a result of international obligations under the Convention on International Civil Aviation, no public consultation was required, and the Office of Best Practice Regulation has determined that such ADs do not need a Regulatory Impact Statement.
The obligations imposed on parties under these regulations are substantial. CASA must rigorously assess any AD issued by the State of Design and determine whether it should be implemented in Australia. If an AD is deemed necessary, CASA issues an Australian AD to mandate compliance with the requirements. This process ensures that aircraft registered in Australia meet international safety standards. Additionally, the AD cancellation mechanism ensures that unnecessary or outdated directives are removed, thereby preventing unnecessary burdens on aircraft operators while maintaining safety.
Failure to comply with ADs can have serious consequences. Under section 78 of the Civil Aviation Act 1988, non-compliance with airworthiness directives can lead to civil penalties, including fines and imprisonment. Specifically, section 78(1) of the Act imposes fines and imprisonment for failing to comply with ADs, with maximum penalties depending on the severity of the offence. For example, serious violations can result in fines of up to $162,000 for individuals and $810,000 for corporations, as well as imprisonment for up to five years. These stringent penalties underscore the importance of adhering to ADs to maintain the highest safety standards in aviation.
