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, the Civil Aviation Safety Authority (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.
CASA or its predecessors issued AD/TSA-600/40 Amdt 1 affecting Aerostar aircraft. CASA has reviewed this AD and as a result has cancelled it. The cancellation will become effective on 4 June 2009. No replacement AD is required.
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 regulate civil aviation safety within Australia, ensuring the protection of the public and promoting safe and efficient air navigation. This Act provides the legislative foundation for the development of regulations that govern various aspects of aviation safety, including the issuance of airworthiness directives by the Civil Aviation Safety Authority (CASA). In 1998, the Civil Aviation Safety Regulations were established to further detail the requirements for maintaining aircraft and aeronautical products' airworthiness. Under these regulations, CASA has the authority to issue airworthiness directives for specific types of aircraft or aeronautical products to maintain and ensure safety standards. The issuance of these directives is recognised as a legislative instrument under the Acts Interpretation Act 1901 and the Legislative Instruments Act 2003. The process of issuing and cancelling such directives, including AD/TSA-600/40 Amdt 1 for Aerostar aircraft, is conducted in accordance with Australia's obligations under the Convention on International Civil Aviation and relevant domestic legislation.
Scope and Application
The Civil Aviation Act 1988, as amended and supplemented by the Civil Aviation Safety Regulations 1998, provides a comprehensive framework for ensuring the safety of air navigation within Australia. Under this legislative structure, the Civil Aviation Safety Authority (CASA) has the authority to issue airworthiness directives (ADs) for specific types of aircraft and aeronautical products. These directives are intended to maintain the continuing airworthiness of aircraft and are aligned with the requirements of Annex 8 to the Convention on International Civil Aviation, which mandates that the State of Design and the State of Registry both have responsibilities towards ensuring that aircraft remain airworthy. The ADs issued by CASA are legislative instruments, and as such, they are subject to disallowance under section 46A of the Acts Interpretation Act 1901. The process of issuing and cancelling ADs is conducted in accordance with the provisions of the Civil Aviation Act 1988 and related regulations, with specific authority vested in the Manager, Systems and New Technologies within CASA’s Airworthiness Engineering Group. In the specific instance of AD/TSA-600/40 Amdt 1 affecting Aerostar aircraft, CASA has determined that the directive should be cancelled, reflecting Australia’s obligations under international conventions, and no public consultation or regulatory impact statement was deemed necessary for this action.
Key Provisions
The main operative sections of the Civil Aviation Act 1988, as relevant to the issuance and cancellation of airworthiness directives (ADs), are sections 98 and 84A. Section 98 allows the Governor-General to make regulations for the safety of air navigation, and section 84A empowers the Civil Aviation Safety Authority (CASA) to issue ADs for kinds of aircraft or aeronautical products, ensuring compliance with safety standards. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 formalises this process, providing that ADs are a legislative instrument under the Acts Interpretation Act 1901 and the Legislative Instruments Act 2003.
The obligations and requirements imposed by the Act on CASA and other parties include ensuring the continuing airworthiness of aircraft, as per Annex 8 of the Convention on International Civil Aviation. CASA, as the authority responsible for issuing ADs, must follow the processes outlined in the regulations and consider international obligations, particularly those stemming from the Convention. The State of Registry, which in this case is Australia, is responsible for developing or adopting requirements to ensure the continuing airworthiness of aircraft within its jurisdiction. CASA must ensure that any ADs issued are aligned with international standards and obligations, including the provision of necessary information to other Contracting States.
Offences, penalties, or civil/criminal consequences for breach of ADs are not explicitly detailed in the provided text. However, non-compliance with ADs could lead to safety violations, potentially resulting in civil or criminal penalties under broader aviation safety laws. While specific maximum penalties are not stated in this context, general aviation safety legislation often includes provisions for fines and imprisonment for breaches that result in serious harm or endangerment. The revocation or cancellation of an AD, such as the one affecting Aerostar aircraft, underscores the seriousness with which CASA treats compliance with airworthiness standards.
In summary, the Civil Aviation Act 1988 and the associated regulations provide a framework for issuing and managing ADs to maintain air safety. CASA's role in this framework includes ensuring that ADs are issued in accordance with international standards and obligations, and that any breaches of these directives are addressed appropriately. The legislative process and international responsibilities highlighted in the text demonstrate the importance of coordinated efforts in ensuring the safety of air navigation.
