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 2008-10-10 affecting Boeing 737-600, -700,
-700C, -800 and -900 series aircraft. The United States is the State of Design for these types. CASA has assessed this AD and has issued Australian AD/B737/329, which will become effective on 3 July 2008.
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, Systems and New Technologies in the Airworthiness Engineering Branch, on behalf of CASA, in accordance with subsection 84A (2) of the Act.
Overview
The Civil Aviation Act 1988, enacted to ensure the safety of air navigation and to provide a comprehensive regulatory framework for civil aviation, empowers the Governor-General to make regulations in the interest of safety. One significant aspect of this legislation is the issuance of airworthiness directives (ADs), which are regulatory instruments used to mandate compliance with safety standards for specific aircraft types or aeronautical products. Under regulation 39.001 of the Civil Aviation Safety Regulations 1998, the Civil Aviation Safety Authority (CASA) can issue these directives, which are considered legislative instruments under the Legislative Instruments Act 2008. The ADs are crucial for maintaining the continuing airworthiness of aircraft and are issued in accordance with the requirements set forth by the International Civil Aviation Organization (ICAO). In the case of foreign ADs, such as the one issued by the United States Federal Aviation Administration (FAA) for Boeing 737 aircraft, CASA evaluates and, if necessary, issues corresponding Australian ADs to align with international safety standards. This process ensures that Australian-registered aircraft meet global safety requirements without necessitating public consultation due to the nature of international obligations and the technical basis of ADs.
Scope and Application
The Civil Aviation Safety Regulations 1998, specifically regulation 39.001, empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for certain types of aircraft or aeronautical products. These directives are legislative instruments that pertain to the continuing airworthiness of aircraft and are issued in accordance with section 98 of the Civil Aviation Act 1988, with the overarching aim of ensuring the safety of air navigation. The ADs are intended to mandate requirements that ensure compliance with international standards, particularly those set by the International Civil Aviation Organization (ICAO) under Annex 8. The State of Design, which in the case of Boeing 737 series aircraft is the United States, has the responsibility to provide information necessary for the continuing airworthiness of an aircraft type. CASA, as Australia's national airworthiness authority, must then assess this information and, if appropriate, issue an Australian AD to enforce the requirements of the State of Design. This process is mandated by Australia's obligations under the Convention on International Civil Aviation, and thus does not require public consultation or a Regulatory Impact Statement. The issuance of such directives is a direct extension of the legislative framework provided by the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998, ensuring that Australian aviation standards remain aligned with international safety protocols.
Key Provisions
The Civil Aviation Act 1988 (the Act) authorises the Governor-General to make regulations aimed at ensuring the safety of air navigation. This authority is exercised through the Civil Aviation Safety Regulations 1998 (CASR), which provide, under regulation 39.001, that the Civil Aviation Safety Authority (CASA) can issue airworthiness directives (ADs) for certain types of aircraft or aeronautical products. Section 98 of the Act and regulation 39.001 empower CASA to issue ADs, which are considered legislative instruments under the Legislative Instruments Act 2003. These ADs are essential for maintaining the continuing airworthiness of aircraft, a responsibility that falls on the State of Registry under Annex 8 to the Convention on International Civil Aviation. In the context of Australia, CASA, as the national airworthiness authority, must assess information provided by the State of Design and issue an Australian AD if necessary.
The obligations imposed by the Act and the CASR on parties and entities governed by these provisions are primarily centred around ensuring the continuing airworthiness of aircraft. The State of Design, responsible for the type of aircraft, must provide necessary information to the States of Registry, including Australia. CASA, as the State of Registry for Australian-registered aircraft, must then assess this information and, if required, issue an Australian AD. These ADs mandate specific actions to be taken to ensure compliance with airworthiness standards. The process is designed to maintain safety standards and ensure that all aircraft, regardless of their country of design, meet the necessary safety requirements when operating in Australia.
Breaching the requirements set out in the ADs can lead to significant consequences. Under section 84A of the Act, failure to comply with an AD can be considered an offence, leading to potential civil or criminal penalties. The specific consequences for non-compliance are not detailed in the provided text, but in general, such breaches can result in fines, imprisonment, or both, depending on the severity of the violation and the discretion of the court. The seriousness of these penalties reflects the importance of adhering to airworthiness directives in maintaining the safety of air navigation.
Additionally, the issuance of ADs under the CASR is subject to certain procedural requirements to ensure transparency and accountability. However, the provided text notes that ADs, such as the one issued in response to the United States Federal Aviation Administration’s AD 2008-10-10, do not require public consultation or a Regulatory Impact Statement. This exemption is based on the determination by the Office of Best Practice Regulation that such instruments do not necessitate these additional steps. The AD in question was issued by the Manager, Systems and New Technologies in the Airworthiness Engineering Branch, on behalf of CASA, in accordance with subsection 84A(2) of the Act. This highlights the streamlined process for issuing ADs aimed at quickly addressing safety concerns without undue delay.
