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/INST/28 affecting ARC PA-1050A Actuators and DA-1050A Decoupler Adaptors. CASA has assessed this AD and as a result has cancelled Australian AD/INST/28. The cancellation will become effective on 12 March 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, Systems and New Technologies, 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 provide for the safety of civil aviation in Australia and to regulate matters related to civil aviation. This legislation was introduced to address the need for a comprehensive legal framework to ensure the safety of air navigation and aircraft. The Act empowers the Governor-General to make regulations that support its objectives, such as issuing airworthiness directives. In accordance with section 98 of the Act, the Civil Aviation Safety Regulations 1998 were established, under which the Civil Aviation Safety Authority (CASA) is authorised to issue airworthiness directives for specific types of aircraft or aeronautical products. This regulatory mechanism is crucial for maintaining the continuing airworthiness of aircraft and ensuring compliance with international standards as outlined in Annex 8 to the Convention on International Civil Aviation. The policy objective of these regulations is to uphold the highest standards of safety in civil aviation through effective regulatory oversight.
Scope and Application
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 together establish the framework for the issuance and management of airworthiness directives (ADs) in Australia, with a particular focus on ensuring the safety of air navigation. Pursuant to section 98 of the Civil Aviation Act 1988, the Governor-General is empowered to enact regulations under the Act, while regulation 39.001 of the Civil Aviation Safety Regulations 1998 specifically allows the Civil Aviation Safety Authority (CASA) to issue ADs for specific types of aircraft or aeronautical products. An AD is considered a legislative instrument under the Legislative Instruments Act 2003, and its disallowance is governed by section 46A of the Acts Interpretation Act 1901. The scope of these regulations is broad, applying to all aircraft registered in Australia, their operators, and relevant aeronautical products, with the primary goal of maintaining airworthiness standards. The geographic reach of these regulations is national, as CASA acts as Australia’s national airworthiness authority. However, ADs are also subject to international obligations, particularly under Annex 8 to the Convention on International Civil Aviation, which mandates that the State of Design must provide necessary information for the continuing airworthiness of an aircraft type. Consequently, when a State of Design issues an AD, CASA must evaluate and, if necessary, issue a corresponding Australian AD to ensure compliance with international standards. The cancellation of Australian AD/INST/28 for ARC PA-1050A Actuators and DA-1050A Decoupler Adaptors, for instance, reflects CASA’s adherence to these international obligations, as the unsafe condition addressed by the AD no longer exists.
Key Provisions
The Civil Aviation Act 1988, supplemented by the Civil Aviation Safety Regulations 1998, establishes the framework for ensuring the safety of air navigation in Australia. Specifically, section 98 of the Civil Aviation Act 1988 empowers the Governor-General to create regulations in the interest of air navigation safety, while regulation 39.001 of the Civil Aviation Safety Regulations 1998 enables the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) concerning certain types of aircraft or aeronautical products. Furthermore, subregulation 39.001(5) classifies ADs as disallowable instruments under section 46A of the Acts Interpretation Act 1901, making them legislative instruments under the Legislative Instruments Act 2003.
The obligations imposed by these regulations necessitate that the State of Design, which is the country where the aircraft is designed, take responsibility for the continuing airworthiness of an aircraft type, providing necessary information to States of Registry to ensure compliance with airworthiness standards. The State of Registry, in turn, must develop or adopt requirements to maintain the continuing airworthiness of aircraft registered within its jurisdiction. In Australia, CASA acts as the national airworthiness authority and must evaluate ADs issued by the State of Design. If an AD is relevant to aircraft registered in Australia, CASA may issue a corresponding Australian AD to enforce the requirements stipulated by the State of Design.
The Civil Aviation Safety Regulations 1998 also address the issuance of specific ADs, such as AD/INST/28, which pertained to ARC PA-1050A Actuators and DA-1050A Decoupler Adaptors. CASA assessed the AD and determined that the unsafe condition no longer existed, leading to the cancellation of Australian AD/INST/28, effective from 12 March 2009. Given that this cancellation was due to obligations under the Convention on International Civil Aviation, no public consultation or Regulatory Impact Statement was required. The AD was issued by the Manager, Systems and New Technologies, within CASA's Airworthiness Engineering Group, in compliance with subsection 84A(2) of the Civil Aviation Act 1988.
The implications of breaching the provisions of these regulations can be severe. Non-compliance with airworthiness directives or failure to adhere to the requirements set forth by CASA can result in significant penalties. For civil violations, the maximum penalty can include fines of up to $21,000 for individuals and $105,000 for corporations. Additionally, criminal sanctions may apply, including imprisonment for up to two years for individuals, reflecting the critical importance of adhering to these regulations to ensure the safety of air navigation.
