CIVIL AVIATION ACT 1988
CIVIL AVIATION 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-2004-21R1 affecting Bell 430 model aircraft. Canada is the State of Design for this type. CASA has assessed this AD and has issued Australian AD/BELL 430/1 Amendment 2, which will become effective on17 March 2005. This AD cancels and replaces the previous issue.
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 Acting Section Head - Airframes, Airworthiness Standards Branch, Standards Division, 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 activities within Australia. This legislation was introduced to ensure the safety and efficiency of air navigation and operations. Under this Act, the Civil Aviation Safety Regulations 1998 were established to provide further detail on safety standards and practices, including the issuance of airworthiness directives (ADs). An AD is a legislative instrument created to maintain the continuing airworthiness of aircraft, mandated by the State of Registry and in response to international obligations under the Convention on International Civil Aviation. The Civil Aviation (Airworthiness) Regulations 1998 empower the Civil Aviation Safety Authority (CASA) to issue these directives, ensuring compliance with safety standards set by the State of Design, such as Transport Canada in the case of the Bell 430 model aircraft. This regulatory framework underscores Australia’s commitment to international aviation safety standards and the ongoing management of aircraft airworthiness within its jurisdiction.
Scope and Application
The Civil Aviation Act 1988 and its associated regulations, including the Civil Aviation Safety Regulations 1998, establish a regulatory framework that governs the issuance of airworthiness directives (ADs) by the Civil Aviation Safety Authority (CASA) in Australia. Under these provisions, CASA is empowered to issue ADs for specific kinds of aircraft or aeronautical products to ensure the safety of air navigation. These ADs serve as legislative instruments under the Acts Interpretation Act 1901 and the Legislative Instruments Act 2003. The ADs are primarily issued in response to obligations under the Convention on International Civil Aviation, where the State of Design has the responsibility for the continuing airworthiness of an aircraft type. CASA, as Australia’s national airworthiness authority, must assess information provided by the State of Design and subsequently issue Australian ADs as necessary. This process ensures that all aircraft registered in Australia meet the continuing airworthiness standards set forth by the State of Registry. In the instance of Transport Canada’s AD CF-2004-21R1 concerning Bell 430 model aircraft, CASA has issued a corresponding Australian AD/BELL 430/1 Amendment 2, effective from 17 March 2005, which replaces the previous directive. As these ADs are issued in compliance with international obligations, no public consultation or Regulatory Impact Statement is required, as determined by the Office of Regulatory Review. The ADs are made by authorised personnel within CASA, adhering to the statutory requirements under the Civil Aviation Act 1988.
Key Provisions
The Civil Aviation Act 1988 and its associated regulations provide the legal framework for ensuring the safety and airworthiness of aircraft within Australia. Section 98 of the Act grants the Governor-General the authority to make regulations that serve the interests of air navigation safety. 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 directives are considered legislative instruments under section 6 of the Legislative Instruments Act 2003 and are subject to disallowance provisions as outlined in section 46A of the Acts Interpretation Act 1901.
Under these provisions, the State of Design holds the primary responsibility for ensuring the continuing airworthiness of an aircraft type, including providing necessary information to States of Registry as per Annex 8 to the Convention on International Civil Aviation. The State of Registry, which in Australia's case is CASA, must then assess the ADs issued by the State of Design and, if appropriate, issue corresponding Australian ADs to mandate the required safety measures. For instance, following an AD issued by Transport Canada concerning the Bell 430 model aircraft, CASA has issued Australian AD/BELL 430/1 Amendment 2, which mandates specific requirements for the aircraft's continued airworthiness in Australia.
The obligations imposed by these regulations include ensuring that the State of Design provides all necessary information for continuing airworthiness and that the State of Registry, represented by CASA in Australia, assesses and enforces these directives. CASA must also ensure that these directives are issued in accordance with the legislative requirements and are aligned with international standards set by ICAO. This involves rigorous assessment processes and adherence to the Convention on International Civil Aviation, ensuring that all safety measures are consistently applied across the Australian aviation industry.
Any failure to comply with the ADs can lead to significant legal consequences. Non-compliance with an AD is considered an offence under the Civil Aviation Act 1988, and violators may face substantial penalties. The exact penalties can vary but often include fines and potential imprisonment. CASA has the authority to enforce these regulations, and non-compliance can result in serious civil or criminal penalties, reflecting the critical importance of adhering to airworthiness directives for maintaining aviation safety standards.
