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-2001-44 affecting Bombardier DHC 8-400 aeroplanes. Canada is the State of Design for these aeroplanes. CASA has assessed this AD and has issued Australian AD/DHC-8/118, which will become effective on 13 April 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 was enacted to provide a legal framework for the regulation of civil aviation in Australia, ensuring the safety and efficiency of air navigation. It empowers the Governor-General to make regulations for the purposes of the Act and in the interests of the safety of air navigation. One such regulation, made under section 98 of the Act, allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for kinds of aircraft or aeronautical products as specified in regulation 39.001 of the Civil Aviation Safety Regulations 1998. These ADs are legislative instruments that are subject to disallowance and must be made in accordance with the Legislative Instruments Act 2003. The ADs are necessary to ensure compliance with Australia's obligations under international agreements, such as Annex 8 to the Convention on International Civil Aviation, which mandates that States of Design and States of Registry are responsible for the continuing airworthiness of aircraft. This legislative framework allows CASA to issue Australian ADs in response to directives from the relevant State of Design, thereby maintaining the safety standards required by international standards.
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 certain types of aircraft or aeronautical products to ensure the safety of air navigation. These ADs, which are legislative instruments, are issued in accordance with international standards set by the International Civil Aviation Organization (ICAO) and are mandated by Australia’s obligations under the Convention on International Civil Aviation. The ADs serve as a crucial means for the State of Design to communicate necessary information to States of Registry, including Australia, to maintain the continuing airworthiness of aircraft types. CASA, as Australia's national airworthiness authority, is responsible for assessing ADs issued by other countries and, if deemed appropriate, issuing corresponding Australian ADs to enforce these safety requirements. This process underscores Australia's commitment to international aviation safety standards while ensuring that domestic aviation regulations are upheld.
Key Provisions
The Civil Aviation Act 1988, particularly section 98, empowers the Governor-General to enact regulations aimed at enhancing the safety of air navigation. This authority is exercised through the Civil Aviation Safety Regulations 1998, where regulation 39.001 allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. Section 39.001(5) further clarifies that an AD is considered a disallowable instrument under section 46A of the Acts Interpretation Act 1901, and thus, it is a legislative instrument as per section 6 of the Legislative Instruments Act 2003. These regulations are rooted in Annex 8 to the Convention on International Civil Aviation, which stipulates that the State of Design has primary responsibility for the continuing airworthiness of an aircraft type and must share necessary information with the States of Registry to maintain airworthiness standards. Consequently, CASA, as Australia’s national airworthiness authority, is obligated to assess and, if necessary, issue Australian ADs to implement the requirements outlined by the State of Design.
The obligations imposed on entities by the Civil Aviation Safety Regulations 1998 include the State of Design's duty to provide comprehensive information to ensure the continuing airworthiness of aircraft types. The State of Registry must then develop or adopt the requisite requirements to maintain the airworthiness of individual aircraft. When an AD is issued by a State of Design, CASA must evaluate this information and, if deemed appropriate, issue a corresponding Australian AD. This process is exemplified by the issuance of AD CF-2001-44 by Transport Canada concerning Bombardier DHC 8-400 aeroplanes. As Canada is the State of Design for these aircraft, CASA has assessed and issued Australian AD/DHC-8/118, which will take effect on 13 April 2006.
Given the nature of ADs and their alignment with international obligations under the Convention on International Civil Aviation, Australia does not undertake public consultation on these directives. The Office of Regulatory Review has concluded that ADs do not necessitate a Regulatory Impact Statement. The AD in question was formulated by the Manager, New Technologies and Systems, within CASA’s Manufacturing, Certification and New Technologies Office, in accordance with subsection 84A(2) of the Act. This legal framework ensures that CASA adheres to international standards while maintaining the airworthiness of aircraft registered in Australia.
In terms of consequences for non-compliance, breaches of airworthiness directives can lead to serious safety risks and potential legal ramifications. While the Civil Aviation Safety Regulations 1998 do not explicitly detail specific offences, penalties, or civil/criminal consequences, non-compliance with ADs could result in severe civil aviation safety breaches. Such breaches might lead to aircraft being grounded, operations being halted, or severe penalties being imposed on the aircraft operator or owner. Additionally, CASA has the authority to enforce compliance through various regulatory measures, which could include fines, suspension of airworthiness certificates, or even criminal charges in cases of gross negligence or willful disregard for safety directives. The precise penalties would depend on the severity of the breach and the specific circumstances involved.
