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 European Aviation Safety Authority (EASA) has issued AD 2007-0064R1 affecting Airbus A319, A320 and A321 model aircraft. EASA acts on behalf of France, the State of Design for these types. CASA has assessed this AD and has issued Australian AD/A320/205, Amendment 1, which will become effective on 22 November 2007. 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 Best Practice Regulation has determined that ADs do not require a Regulatory Impact Statement.
The AD has been made by the Manager, Airframes in the Airworthiness Engineering Branch, on behalf of CASA, in accordance with subsection 84A (2) of the Act.
Overview
The Civil Aviation Act 1988 was enacted to ensure the safety of air navigation and establish a regulatory framework for civil aviation in Australia. This legislation grants the Governor-General the authority to make regulations under section 98, and these regulations are pivotal in maintaining the safety standards of air navigation. The Civil Aviation Safety Regulations 1998 further elaborate on the process by which the Civil Aviation Safety Authority (CASA) can issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. These ADs serve as a legislative instrument, necessary to ensure compliance with international standards, particularly those set by the Convention on International Civil Aviation. The ADs are crucial for maintaining the continuing airworthiness of aircraft as mandated by the relevant State of Design and the State of Registry. CASA, as Australia’s national airworthiness authority, evaluates and issues these ADs to align with international obligations and ensure the safety of aircraft operating within Australian airspace.
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. This authority is exercised under the overarching provisions of the Civil Aviation Act 1988, which mandates CASA’s role in ensuring the safety of air navigation. These directives, which include legislative instruments as per the Legislative Instruments Act 2003, are essential for maintaining the continuing airworthiness of aircraft registered in Australia. The ADs are issued in response to directives from the State of Design, which has the primary responsibility for ensuring the airworthiness of an aircraft type. The State of Registry, in this case CASA, must then assess and implement these directives, ensuring compliance with international standards set by the International Civil Aviation Organization (ICAO). Exemptions and exclusions from these regulations are not explicitly mentioned in the provided text, but it is understood that the ADs are issued under the authority of international conventions and Australian law, without the need for public consultation or a Regulatory Impact Statement. The ADs are thus an integral part of the regulatory framework that ensures the safety and airworthiness of aircraft operating in Australia.
Key Provisions
The Civil Aviation Act 1988, under section 98, empowers the Governor-General to create regulations aimed at ensuring the safety of air navigation. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 specifically authorises the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for certain types of aircraft or aeronautical products. These directives are intended to maintain or ensure the airworthiness of these aircraft. Subregulation 39.001(5) clarifies that an AD is a disallowable instrument under section 46A of the Acts Interpretation Act 1901, thus classifying it as a legislative instrument under section 6 of the Legislative Instruments Act 2003.
The obligations imposed by these regulations are significant. The State of Design, which is the country where an aircraft type is designed, holds the primary responsibility for the continuing airworthiness of that aircraft type. This includes providing necessary information to the State of Registry, which is the country where the aircraft is registered, to ensure the aircraft's ongoing airworthiness. In the case of Australia, CASA, as the national airworthiness authority, must assess the information provided by the State of Design and, if deemed necessary, issue an Australian AD to enforce the requirements of the State of Design on aircraft registered in Australia. For example, the European Aviation Safety Authority (EASA) issued AD 2007-0064R1 concerning Airbus A319, A320, and A321 models, prompting CASA to issue Australian AD/A320/205, Amendment 1, effective from 22 November 2007.
The ADs carry strict compliance requirements and potential consequences for non-compliance. Failure to adhere to the mandated airworthiness directives can result in serious safety risks, leading to regulatory actions against the aircraft operators. While specific penalties are not detailed in the provided text, it is evident that non-compliance with ADs can result in severe regulatory and legal consequences, including the grounding of aircraft, fines, and other sanctions. These directives are critical to maintaining the safety standards required under international aviation regulations, particularly those stipulated in Annex 8 to the Convention on International Civil Aviation.
