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/AUS/8 affecting Auster/Beagle A.61 series aeroplanes. CASA has assessed this AD and as a result has cancelled Australian AD/AUS/8. The cancellation will become effective on 30 July 2009. 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, Airframe and Structures, in the Airworthiness Engineering Group, on behalf of CASA, in accordance with subsection 84A (2) of the Act.
Overview
The Civil Aviation Act 1988 was enacted to regulate civil aviation in Australia and ensure safety in air navigation. Under this Act, the Civil Aviation Safety Regulations 1998 were also introduced to provide further detail on operational safety standards. The Act empowers the Governor-General to make regulations, and section 98 specifically allows for the creation of airworthiness directives to enhance aviation safety. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 allows the Civil Aviation Safety Authority (CASA) to issue such directives for specific types of aircraft or aeronautical products, which are considered legislative instruments under the Legislative Instruments Act 2003. The primary policy objective behind these regulations is to ensure that all aircraft operating in Australian airspace meet stringent safety standards, aligning with international obligations under the Convention on International Civil Aviation.
Scope and Application
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 provide the legislative framework for issuing airworthiness directives (ADs) in Australia, ensuring the safety of air navigation and the continuing airworthiness of aircraft. 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. These ADs, which are legislative instruments, are made to comply with Australia’s obligations under Annex 8 to the Convention on International Civil Aviation, where the State of Design holds responsibility for the continuing airworthiness of aircraft types. The State of Registry, in this case CASA, must then assess this information and, if necessary, issue an Australian AD to enforce the requirements from the State of Design. The AD in question, AD/AUS/8 affecting Auster/Beagle A.61 series aeroplanes, has been cancelled as the unsafe condition it was addressing no longer exists, and no replacement AD is required. This cancellation was made in accordance with the Act and has not required public consultation or a Regulatory Impact Statement.
Key Provisions
The Civil Aviation Act 1988, particularly in conjunction with the Civil Aviation Safety Regulations 1998, provides the legislative framework under which the Civil Aviation Safety Authority (CASA) can issue airworthiness directives (ADs) (sections 98 and 39.001). These directives serve as a means to ensure that aircraft and aeronautical products maintain their airworthiness and safety standards, as required by international agreements under Annex 8 to the Convention on International Civil Aviation. The ADs are legally binding once issued and serve to mandate specific actions or checks that must be carried out on particular types of aircraft.
The obligations imposed by the Act and the Regulations on the parties involved are significant. The State of Design, which is the country where the aircraft type is designed, has the primary responsibility to provide information and directives to ensure the aircraft's continuing airworthiness. The State of Registry, which is the country where the aircraft is registered, must then implement these directives and ensure compliance within its jurisdiction. CASA, as Australia’s national airworthiness authority, must review the directives issued by the State of Design and, if appropriate, issue an Australian AD that enforces these requirements domestically.
Failure to comply with an AD can result in serious consequences. The Act does not explicitly state penalties for non-compliance with ADs, but non-compliance could potentially lead to severe civil and criminal consequences, including the grounding of an aircraft, fines, and even imprisonment. The severity of the penalty depends on the nature of the non-compliance and its impact on aviation safety. It is also worth noting that ADs are legislative instruments, which means they are subject to disallowance by Parliament under section 46A of the Acts Interpretation Act 1901.
In the specific case of AD/AUS/8 affecting Auster/Beagle A.61 series aeroplanes, CASA has cancelled the directive because the unsafe condition it was addressing no longer exists. This cancellation was made in line with Australia’s international obligations and does not require public consultation or a Regulatory Impact Statement, as determined by the Office of Best Practice Regulation. The Manager, Airframe and Structures, within CASA’s Airworthiness Engineering Group, made this decision in accordance with the legislative powers granted under section 84A(2) of the Civil Aviation Act 1988.
