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 2003-23-03 affecting Boeing 737 model aircraft. The USA is the State of Design for this type. CASA has assessed this AD and has issued Australian AD/B737/266, which will become effective on 22 December 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 legal framework for civil aviation in Australia, ensuring safety and efficiency in the operation of aircraft. The Act empowers the Governor-General to make regulations for the purposes of the Act, specifically under section 98, which allows for the regulation of air navigation safety. The Civil Aviation Safety Regulations 1998 further detail the implementation of these regulations, with regulation 39.001 specifically allowing the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for certain types of aircraft or aeronautical products. These ADs serve as a critical tool in maintaining the continuing airworthiness of aircraft and are subject to disallowance and thus considered legislative instruments under the Legislative Instruments Act 2003.
In accordance with international obligations under Annex 8 to the Convention on International Civil Aviation, CASA, as Australia’s national airworthiness authority, is tasked with issuing ADs that align with directives from the State of Design when necessary. This ensures that Australian-registered aircraft meet international safety standards. For instance, following the issuance of an AD by the US Federal Aviation Administration (FAA) concerning Boeing 737 aircraft, CASA has assessed the directive and issued its own AD to mandate the requirements for Australian operators. This process highlights the importance of international cooperation in maintaining air safety standards, and while ADs are legislative instruments, they do not require public consultation or a Regulatory Impact Statement as determined by the Office of Regulatory Review.
Scope and Application
The Civil Aviation Act 1988, alongside the Civil Aviation Safety Regulations 1998, provides the framework for the regulation of airworthiness directives (ADs) in Australia, ensuring the safety of air navigation as per section 98 of the Act. Under regulation 39.001 of the Civil Aviation Safety Regulations 1998, the Civil Aviation Safety Authority (CASA) is empowered to issue ADs for specific types of aircraft or aeronautical products, and these directives are legislative instruments as per section 46A of the Acts Interpretation Act 1901 and section 6 of the Legislative Instruments Act 2003. The ADs issued by CASA, such as the Australian AD/B737/266 in response to the US FAA’s AD 2003-23-03 for Boeing 737 model aircraft, are mandated by Australia’s obligations under the Convention on International Civil Aviation. The issuing of such directives does not require consultation with the Australian public or a Regulatory Impact Statement, as determined by the Office of Regulatory Review. This legislative framework ensures that Australia's national airworthiness authority, CASA, can mandate safety requirements for aircraft registered in Australia, thereby fulfilling the responsibilities of the State of Registry under Annex 8 of the Convention.
Key Provisions
The key operative sections of the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 establish the framework within which airworthiness directives (ADs) are issued and enforced. Section 98 of the Civil Aviation Act 1988 empowers the Governor-General to make regulations for the safety of air navigation, while regulation 39.001 of the Civil Aviation Safety Regulations 1998 allows the Civil Aviation Safety Authority (CASA) to issue ADs for types of aircraft or aeronautical products. These ADs are critical tools for ensuring the continuing airworthiness of aircraft, and are considered legislative instruments under the Legislative Instruments Act 2003.
The obligations imposed by the Act and the Regulations on the parties governed by them are significant. The State of Design, which is the country where the aircraft was designed, has the primary responsibility for ensuring the continuing airworthiness of an aircraft type and must provide necessary information to the States of Registry. In Australia, CASA, as the national airworthiness authority, must assess this information and issue an Australian AD if appropriate. This means CASA must thoroughly evaluate foreign ADs, such as the one issued by the US Federal Aviation Administration (FAA) for Boeing 737 model aircraft, and determine if they apply to aircraft registered in Australia. If deemed necessary, CASA will issue a corresponding Australian AD.
Breaching the requirements of an AD can lead to severe consequences. Under the Civil Aviation Act 1988, non-compliance with an AD can result in both civil and criminal penalties. Civil penalties can include fines, while criminal penalties may include imprisonment, reflecting the serious nature of ensuring aviation safety. The exact penalties depend on the specific circumstances of the breach, but the potential for significant financial and legal repercussions underscores the importance of adhering to ADs. The authority to issue these directives and the penalties for non-compliance are essential components of the regulatory framework designed to maintain the highest safety standards in civil aviation.
