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-2006-08 affecting Bombardier DHC-8 aeroplanes. Canada is the State of Design for these aeroplanes. CASA has assessed this AD and has issued Australian AD/DHC-8/120, which will become effective on 31 May 2006.
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 Regulatory Review has determined that ADs do not require a Regulatory Impact Statement.
The AD has been made by the Manager, New Technologies and Systems, in the Manufacturing, Certification and New Technologies Office, on behalf of CASA, in accordance with subsection 84A (2) of the Act.
Overview
The Civil Aviation Act 1988, enacted by the Commonwealth Parliament, serves to regulate civil aviation in Australia, with a primary focus on ensuring the safety of air navigation. This Act empowers the Governor-General to make regulations that uphold the safety standards of air navigation, and it provides the Civil Aviation Safety Authority (CASA) with the authority to issue airworthiness directives (ADs) under regulation 39.001 of the Civil Aviation Safety Regulations 1998. These directives are crucial for maintaining the continuing airworthiness of aircraft types and aeronautical products, aligning with Australia's commitments under the Convention on International Civil Aviation. The policy objective of these regulations is to ensure that all aircraft operating within Australian airspace meet the necessary safety standards, thereby protecting the public and contributing to the global aviation safety framework.
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) for specific types of aircraft or aeronautical products. These ADs are intended to ensure the continuing airworthiness of aircraft and are applicable to all entities involved in the operation and maintenance of the affected aircraft types, including airlines, maintenance organisations, and aircraft operators. The ADs apply nationally across Australia and are issued in response to international obligations under the Convention on International Civil Aviation. Notably, these directives are subject to disallowance under the Acts Interpretation Act 1901 and are classified as legislative instruments pursuant to the Legislative Instruments Act 2003. The issuance of ADs is a response to actions by the State of Design, and CASA, as Australia’s national airworthiness authority, assesses and may issue corresponding Australian ADs. The ADs are issued without public consultation as they respond to international obligations, and the Office of Regulatory Review has determined that they do not require a Regulatory Impact Statement. The ADs are made by designated CASA officials in accordance with the Civil Aviation Act 1988.
Key Provisions
The Civil Aviation Act 1988, in conjunction with the Civil Aviation Safety Regulations 1998, outlines the framework for the issuance of airworthiness directives (ADs) by the Civil Aviation Safety Authority (CASA). Section 98 of the Act empowers the Governor-General to make regulations for air navigation safety, and regulation 39.001 specifically allows CASA to issue ADs for certain kinds of aircraft or aeronautical products. Under subregulation 39.001(5), ADs are recognised as disallowable instruments, and therefore legislative instruments, as per section 46A of the Acts Interpretation Act 1901 and section 6 of the Legislative Instruments Act 2003. These directives are crucial for ensuring the continuing airworthiness of aircraft, a responsibility held by the State of Design as per Annex 8 to the Convention on International Civil Aviation.
The obligations placed on the parties governed by these provisions are significant. The State of Design, in this case Canada for Bombardier DHC-8 aeroplanes, has the duty to issue ADs to ensure the safety and airworthiness of aircraft types. The State of Registry, in this instance CASA for Australia, must then evaluate these ADs and, if deemed necessary, issue corresponding Australian ADs to mandate the requirements of the State of Design. This process is essential to harmonise safety standards and ensure that all aircraft registered in Australia meet international safety requirements.
Breaches of the provisions outlined in the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 can result in serious consequences. While the specific offences and penalties are not detailed in the provided text, it is clear that non-compliance with ADs could lead to civil or criminal liabilities. The exact nature of these penalties would typically be outlined in more detail within the regulations themselves or related legal frameworks. Given the critical importance of airworthiness directives in maintaining aviation safety, any failure to adhere to these regulations could potentially endanger lives and result in severe legal repercussions.
In summary, the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 establish a robust system for the issuance and enforcement of airworthiness directives, ensuring that both States of Design and States of Registry fulfill their responsibilities under international aviation standards. CASA's role in assessing and issuing Australian ADs is crucial to maintaining the safety and airworthiness of aircraft registered in Australia. Non-compliance with these regulations can have significant legal and safety implications, highlighting the importance of adhering to the outlined provisions.
