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.
Transport Canada has issued AD CF-2007-25 affecting Pratt and Whitney Canada PW305 series engines. Canada is the State of Design for this type. CASA has assessed this AD and has issued Australian AD/PW300/1 which will become effective on 17 January 2008.
As this AD is issued because of Australia’s obligations under Convention on International Civil Aviation, and because it is issued in response to an AD raised by the relevant State of Design, no consultation of the Australian public has taken place on this AD. 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 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 establish a comprehensive legal framework for civil aviation in Australia, ensuring the safety and efficiency of air navigation. This Act empowers the Governor-General to create regulations for the purposes of the Act, primarily to enhance the safety of air navigation. One such regulation, the Civil Aviation Safety Regulations 1998, enables the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific kinds of aircraft or aeronautical products. The ADs are legislative instruments that mandate the continuing airworthiness of aircraft types, aligning with Australia’s obligations under the Convention on International Civil Aviation. The policy objective is to ensure that aircraft maintain their airworthiness, thereby enhancing safety standards in line with international best practices. CASA, acting as Australia’s national airworthiness authority, assesses information from the State of Design and issues Australian ADs as necessary to comply with international standards and ensure domestic safety.
Scope and Application
The Civil Aviation Safety Regulations 1998, under the Civil Aviation Act 1988, empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) concerning specific types of aircraft or aeronautical products. These directives serve as legislative instruments, designed to ensure the safety of air navigation. They are issued in compliance with international standards set out in Annex 8 to the Convention on International Civil Aviation, which mandates that the State of Design has overarching responsibility for the continuing airworthiness of aircraft types, while the State of Registry is responsible for the airworthiness of individual aircraft. When a State of Design issues an AD, CASA must evaluate the information and, if necessary, issue a corresponding Australian AD to enforce the requirements. The issuance of such ADs is driven by international obligations and the need to respond to ADs from other states, and thus, they do not require public consultation or a Regulatory Impact Statement. The ADs are made by authorised personnel within CASA, adhering to the legislative framework provided by the Civil Aviation Act 1988.
Key Provisions
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 establish a framework for ensuring the safety and airworthiness of aircraft in Australia. Section 98 of the Civil Aviation Act 1988 allows the Governor-General to make regulations for the purposes of the Act, particularly focusing on the safety of air navigation. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 empowers the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. These ADs are designed to address safety issues and ensure compliance with safety standards.
Airworthiness directives are legislative instruments under section 6 of the Legislative Instruments Act 2003. They are crucial for maintaining the continuing airworthiness of aircraft, a responsibility shared between the State of Design and the State of Registry, as outlined in Annex 8 to the Convention on International Civil Aviation. The State of Design is responsible for issuing ADs for aircraft types, while the State of Registry, in this case CASA, must assess these directives and issue corresponding ADs for aircraft registered in Australia. This ensures that Australian aircraft meet international safety standards.
The obligations placed on parties governed by this Act include the requirement for CASA to assess ADs issued by the State of Design and to issue corresponding Australian ADs if necessary. This ensures that Australian aircraft comply with international safety standards. For instance, CASA assessed Transport Canada's AD CF-2007-25, which affected Pratt and Whitney Canada PW305 series engines, and subsequently issued Australian AD/PW300/1, effective from 17 January 2008. This process does not require public consultation as it is mandated by international obligations under the Convention on International Civil Aviation.
Failure to comply with ADs can lead to serious safety risks and potential regulatory breaches. While the Act does not explicitly detail specific penalties for non-compliance with ADs, the overarching regulations and safety standards imply severe consequences. Non-compliance can result in enforcement actions, including fines, suspension or revocation of airworthiness certificates, and potential criminal charges. The severity of the penalties reflects the critical importance of adhering to ADs in maintaining aviation safety.
