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 2008-10-12 affecting Air Tractor AT-400 and AT-500 model aircraft. The USA is the State of Design for this type. CASA has assessed this AD and has issued Australian AD/AT/29, 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, 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 provide a comprehensive legal framework for the regulation of civil aviation in Australia, addressing gaps in safety, security, and efficiency within the sector. The Act empowers the Governor-General to make regulations necessary for the safety of air navigation, thereby ensuring that air travel within Australian airspace is conducted with the highest safety standards. The Civil Aviation Safety Regulations 1998, made under the authority of the Act, further detail specific safety requirements, including the issuance of airworthiness directives by the Civil Aviation Safety Authority (CASA). These directives are crucial for maintaining the continuing airworthiness of aircraft and are issued in accordance with international standards set by the Convention on International Civil Aviation. CASA, acting as Australia’s national airworthiness authority, is responsible for issuing these directives, which become effective as legislative instruments under the Acts Interpretation Act 1901. This legislative framework ensures that Australia meets its obligations under international conventions while maintaining stringent domestic safety standards.
Scope and Application
The Civil Aviation Act 1988, as supplemented by the Civil Aviation Safety Regulations 1998, mandates that the Civil Aviation Safety Authority (CASA) can issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. These ADs serve as legislative instruments under the Acts Interpretation Act 1901 and the Legislative Instruments Act 2003, aiming to ensure the continuing airworthiness of aircraft as per international standards set by the International Civil Aviation Organization (ICAO). The ADs are crucial for maintaining safety and compliance with air navigation regulations. The State of Design, such as the United States in the case of Air Tractor AT-400 and AT-500 models, holds the primary responsibility for issuing ADs, which CASA must assess and, if necessary, adopt as Australian ADs. This process reflects Australia's obligations under the Convention on International Civil Aviation and ensures that aircraft registered in Australia meet international safety standards. Exemptions from public consultation and the need for a Regulatory Impact Statement have been determined by the Office of Best Practice Regulation for these ADs, highlighting their technical and regulatory nature.
Key Provisions
The Civil Aviation Act 1988 allows the Governor-General to make regulations that are necessary for the safety of air navigation (section 98). Under regulation 39.001 of the Civil Aviation Safety Regulations 1998, the Civil Aviation Safety Authority (CASA) has the authority to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. These directives are considered legislative instruments as per section 6 of the Legislative Instruments Act 2003, and they are disallowable instruments under section 46A of the Acts Interpretation Act 1901 (subregulation 39.001(5)).
The obligations imposed by the Act and the Regulations are primarily on CASA as the national airworthiness authority. When the State of Design issues an AD, CASA must assess the information and, if appropriate, issue an Australian AD to mandate the requirements of the State of Design (Annex 8, Convention on International Civil Aviation). For example, the US Federal Aviation Administration (FAA) issued AD 2008-10-12 for Air Tractor AT-400 and AT-500 model aircraft, and CASA subsequently issued Australian AD/AT/29, effective from 3 July 2008. Given that these directives are issued in response to international obligations and requirements, no consultation of the Australian public is necessary. Additionally, the Office of Best Practice Regulation has determined that ADs do not require a Regulatory Impact Statement.
Failure to comply with an AD can lead to significant consequences. Under section 45 of the Civil Aviation Act 1988, it is an offence to operate an aircraft in contravention of any applicable AD. Civil penalties for non-compliance can include fines, and in severe cases, criminal penalties may apply. The maximum penalty for a serious breach could be substantial, reflecting the critical importance of adhering to ADs in maintaining airworthiness standards. Therefore, it is essential for operators and owners of affected aircraft to comply with all issued ADs to avoid potential legal and safety repercussions.
