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 have issued AD CF-52-06 affecting Canadian DHC-1 aircraft. Canada is the State of Design for this type. CASA has assessed this AD and has issued Australian AD/DHC-1/41 which will become effective on 12 August 2011.
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 A/Manager, Continuing Airworthiness in the Airworthiness and Engineering Branch, on behalf of CASA, in accordance with subsection 94 (1) of the Act.
Overview
The Civil Aviation Act 1988 was enacted to provide a comprehensive legislative framework governing civil aviation safety in Australia. The Act empowers the Governor-General to make regulations that ensure the safety of air navigation, with the Civil Aviation Safety Regulations 1998 detailing specific requirements. Regulation 39.001 of these regulations enables the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for types of aircraft and aeronautical products, which are legislative instruments under the Legislative Instruments Act 2003. These directives are integral to maintaining the continuing airworthiness of aircraft, in line with international obligations under the Convention on International Civil Aviation. CASA, acting as Australia’s national airworthiness authority, is responsible for assessing and, when necessary, issuing ADs to enforce the requirements of the State of Design. For instance, CASA issued Australian AD/DHC-1/41 in response to Transport Canada’s AD CF-52-06 for Canadian DHC-1 aircraft, reflecting Australia’s commitment to international safety standards. This process does not require public consultation or a Regulatory Impact Statement as it pertains to Australia’s international obligations and is issued by CASA in accordance with the Civil Aviation Act.
Scope and Application
The Civil Aviation Safety Regulations 1998, under section 39.001, empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products, as a means to ensure the continuing airworthiness of such aircraft within Australia. These directives are issued in accordance with the overarching obligations of Australia under the Convention on International Civil Aviation, particularly Annex 8, which assigns the State of Design the responsibility for the continuing airworthiness of an aircraft type. When an AD is issued by a State of Design, CASA, as Australia’s national airworthiness authority, is mandated to assess the information and, if necessary, issue an Australian AD to enforce the requirements of the State of Design. The ADs are legislative instruments, subject to disallowance, and are not required to undergo public consultation or a Regulatory Impact Statement, as determined by the Office of Regulatory Review. The ADs are issued by the A/Manager, Continuing Airworthiness, within the Airworthiness and Engineering Branch, in accordance with the Civil Aviation Act 1988.
Key Provisions
The main operative sections of the Civil Aviation Act 1988, as applied through the Civil Aviation Safety Regulations 1998, empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) under regulation 39.001. This regulation is supported by section 98 of the Act, which allows the Governor-General to create regulations for the safety of air navigation. Specifically, subregulation 39.001(5) clarifies that an AD is a disallowable instrument under section 46A of the Acts Interpretation Act 1901, making it a legislative instrument as per section 6 of the Legislative Instruments Act 2003. These directives are critical for ensuring the continuing airworthiness of aircraft and aeronautical products, aligning with international standards set out in Annex 8 to the Convention on International Civil Aviation.
The obligations imposed by the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 on parties governed by these laws include several key responsibilities. Firstly, the State of Design, which is responsible for the initial airworthiness of an aircraft type, must provide necessary information to the State of Registry to ensure the continuing airworthiness of aircraft. Secondly, the State of Registry must develop or adopt requirements to maintain the airworthiness of individual aircraft. CASA, acting as Australia’s national airworthiness authority, must evaluate any ADs issued by the State of Design and, if appropriate, issue corresponding Australian ADs. This process ensures that Australian-registered aircraft meet safety standards consistent with international obligations.
The implications of breaching the provisions of the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 are significant. While the specific penalties for non-compliance with ADs are not detailed in the provided text, general aviation regulations typically impose both civil and criminal penalties for breaches. Civil penalties can include fines, while criminal penalties may include imprisonment, reflecting the critical nature of air safety. The authority to issue ADs and the stringent requirements for continuing airworthiness underscore the importance of adhering to these regulations to ensure the safety of air navigation.
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 do not mandate public consultation for ADs issued in response to international obligations or directives from the State of Design. This is supported by the Office of Regulatory Review's determination that ADs do not require a Regulatory Impact Statement, highlighting the streamlined process designed to maintain air safety without unnecessary delays. The issuance of ADs, such as the Australian AD/DHC-1/41 in response to Transport Canada’s AD CF-52-06, demonstrates the regulatory framework's efficiency in addressing safety concerns promptly and effectively.
