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.
The US FAA has issued AD 2005-11-09 affecting Boeing B727 model aircraft. The USA is the State of Design for this type. CASA has assessed this AD and has issued Australian AD/B727/194, which will become effective on 1 September 2005.
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, Airframes 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 comprehensive framework for the regulation of civil aviation in Australia, ensuring safety and efficiency in air navigation. The Act empowers the Governor-General to make regulations in the interest of safety, with particular emphasis on the continuing airworthiness of aircraft. In line with this, the Civil Aviation Safety Regulations 1998 were established, allowing the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. This legislative structure was designed to address the need for a unified and internationally compliant approach to aircraft safety, fulfilling Australia’s obligations under the Convention on International Civil Aviation and its annexes. The Civil Aviation Safety Regulations 1998 also specify that ADs are legislative instruments subject to disallowance and review processes, ensuring they meet the required safety standards and are consistent with broader aviation policies.
Scope and Application
The Civil Aviation Act 1988, together with the Civil Aviation Safety Regulations 1998, governs the safety of air navigation in Australia, with the Civil Aviation Safety Authority (CASA) playing a pivotal role in enforcing these regulations. Specifically, under section 98 of the Civil Aviation Act 1988, the Governor-General has the authority to create regulations aimed at enhancing air navigation safety. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 allows CASA to issue airworthiness directives (ADs) for particular types of aircraft or aeronautical products. These ADs, being legislative instruments, are subject to disallowance under section 46A of the Acts Interpretation Act 1901. The ADs serve as a crucial mechanism for maintaining the continuing airworthiness of aircraft as stipulated by Annex 8 to the Convention on International Civil Aviation, which designates the State of Design with overarching responsibility for an aircraft type's airworthiness. In Australia, CASA, as the national airworthiness authority, must assess foreign ADs issued by the State of Design and, if necessary, issue corresponding Australian ADs to ensure compliance and safety. For example, in response to the US Federal Aviation Administration's AD 2005-11-09 for Boeing B727 model aircraft, CASA issued Australian AD/B727/194, which took effect on 1 September 2005. These directives are promulgated without public consultation due to Australia's international obligations under the Convention on International Civil Aviation, and they do not require a Regulatory Impact Statement.
Key Provisions
The Civil Aviation Act 1988, in particular section 98, empowers the Governor-General to create regulations aimed at ensuring the safety of air navigation. This provision is fundamental in enabling the issuance of airworthiness directives (ADs) by the Civil Aviation Safety Authority (CASA) under regulation 39.001 of the Civil Aviation Safety Regulations 1998. The ADs are legal instruments that mandate specific actions to ensure the continuing airworthiness of aircraft types, as detailed in subregulation 39.001(5). These directives are integral to maintaining the safety standards set forth by the Convention on International Civil Aviation, particularly Annex 8, which assigns the State of Design the responsibility for ensuring the continuing airworthiness of aircraft types.
The obligations imposed by these regulations are substantial for both CASA and the State of Registry of individual aircraft. CASA, as Australia's national airworthiness authority, is required to assess information provided by the State of Design and issue corresponding ADs if necessary. This ensures that Australian-registered aircraft comply with international safety standards. Similarly, the State of Registry is tasked with developing or adopting requirements to ensure the continuing airworthiness of aircraft within its jurisdiction. This collaborative approach underscores the importance of international cooperation in maintaining global aviation safety standards.
Non-compliance with the provisions of the ADs can lead to significant consequences. The Civil Aviation Act 1988 outlines various offences and penalties for breaches, although the specific details of these are not fully elaborated in the provided text. Generally, such breaches can result in both civil and criminal penalties, including fines and imprisonment, depending on the severity of the violation and the discretion of the court. The maximum penalties are determined by the nature and extent of the offence, reflecting the critical importance of adhering to airworthiness directives.
In summary, the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 establish a robust framework for issuing airworthiness directives to ensure the safety of aircraft. These regulations impose clear obligations on CASA and the State of Registry to enforce these directives, with significant penalties for non-compliance. The international nature of these requirements highlights the importance of global cooperation in maintaining high standards of aviation safety.
