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 United States FAA has issued AD 99-25-05 affecting Hartzell propeller hubs. The United States is the State of Design for this equipment. CASA has assessed this AD and has issued Australian AD/PHZL/83, which will become effective on 19 January 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 Parliament of Australia, was established to ensure the safety and efficiency of civil aviation in Australia. One of its key provisions is the ability to issue airworthiness directives (ADs) through regulation, specifically under regulation 39.001 of the Civil Aviation Safety Regulations 1998. The Act empowers the Civil Aviation Safety Authority (CASA) to mandate safety requirements for aircraft and aeronautical products, in accordance with international standards set by the Convention on International Civil Aviation, particularly Annex 8 which deals with aircraft airworthiness. This legislative framework aims to maintain and enhance the safety of air navigation by ensuring that aircraft and aeronautical products meet necessary safety standards. ADs, which are legislative instruments under the Legislative Instruments Act 2003, serve as a critical mechanism for enforcing these safety requirements, particularly in response to directives issued by the State of Design of an aircraft type. The Civil Aviation Act 1988 thus provides the foundation for Australia's regulatory oversight in civil aviation, enabling the nation to meet its international obligations while ensuring the safety of its airspace.
Scope and Application
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 provide the legislative framework for the issuance of airworthiness directives (ADs) in Australia. Under section 98 of the Act, the Governor-General has the authority to make regulations in the interest of the safety of air navigation, and regulation 39.001 of the Regulations allows the Civil Aviation Safety Authority (CASA) to issue ADs for specific types of aircraft or aeronautical products. These ADs are legislative instruments that must comply with the Acts Interpretation Act 1901 and the Legislative Instruments Act 2003. The State of Design, which is responsible for the design of an aircraft type, must provide necessary information to ensure the continuing airworthiness of that type, and this responsibility extends to other states under the Convention on International Civil Aviation. The State of Registry, which is the country where the aircraft is registered, must also ensure the continuing airworthiness of individual aircraft, adopting or developing requirements to this end. When an AD is issued by the State of Design, CASA must assess the information and issue an Australian AD if appropriate. This process is exemplified by the issuance of Australian AD/PHZL/83 in response to United States Federal Aviation Administration AD 99-25-05 for Hartzell propeller hubs, where the United States is the State of Design. Due to Australia’s international obligations and the specific nature of ADs, public consultation and regulatory impact statements are not required for these instruments.
Key Provisions
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 provide a framework for the issuance and enforcement of airworthiness directives (ADs) as stipulated in section 98 and regulation 39.001 respectively. The Governor-General can make regulations for the safety of air navigation, and under regulation 39.001, the Civil Aviation Safety Authority (CASA) has the authority to issue ADs for specific types of aircraft or aeronautical products. According to subregulation 39.001(5), an AD is considered a disallowable instrument under section 46A of the Acts Interpretation Act 1901, and as such, it is also recognised as a legislative instrument under section 6 of the Legislative Instruments Act 2003. This legislative status underscores the importance and authority of ADs in maintaining aviation safety.
Under the obligations set forth by the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998, the State of Design holds the primary responsibility for the continuing airworthiness of an aircraft type, as per Annex 8 to the Convention on International Civil Aviation. The State of Design must provide necessary information to ensure the continuing airworthiness of the aircraft type to the relevant States of Registry. In Australia, CASA, as the national airworthiness authority, is tasked with assessing this information when a State of Design issues an AD. If deemed appropriate, CASA must issue an Australian AD to mandate the requirements of the State of Design. Additionally, the State of Registry, which is responsible for the continuing airworthiness of individual aircraft, must develop or adopt requirements to ensure compliance with these mandates.
The issuing of ADs is governed by specific international protocols and obligations. For instance, the United States Federal Aviation Administration (FAA) has issued AD 99-25-05 concerning Hartzell propeller hubs, and since the United States is the State of Design for this equipment, CASA has assessed this directive and issued Australian AD/PHZL/83, effective from 19 January 2006. Given that this AD is issued in response to obligations under the Convention on International Civil Aviation and by the relevant State of Design, there has been no requirement for public consultation. Furthermore, the Office of Regulatory Review has determined that ADs do not necessitate a Regulatory Impact Statement. The AD was made by the Manager, New Technologies and Systems, in the Manufacturing, Certification and New Technologies Office at CASA, in accordance with subsection 84A(2) of the Act.
In terms of compliance and enforcement, any breach of the requirements set forth in an AD could have serious implications. While the specific civil or criminal penalties for non-compliance with ADs are not detailed in the provided text, it is clear that such breaches could potentially lead to severe consequences, including operational restrictions, fines, or even criminal charges. The seriousness of these potential consequences underscores the importance of adhering to ADs to maintain the highest safety standards in aviation.
