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 98-14-09 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/B737/258, 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 legislative framework for the regulation of civil aviation in Australia, ensuring the safety, efficiency, and orderly development of civil aviation within the country. One of the critical mechanisms introduced under this Act is the ability for the Governor-General to make regulations that promote the safety of air navigation. These regulations, such as the Civil Aviation Safety Regulations 1998, empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs). These ADs are legislative instruments designed to mandate specific requirements to maintain the continuing airworthiness of aircraft, reflecting Australia's commitments under international conventions such as the Convention on International Civil Aviation. The authority to issue such directives arises from the Civil Aviation Act and is exercised to meet international obligations and ensure the highest standards of aviation safety are maintained.
Scope and Application
The Civil Aviation Act 1988, supplemented by the Civil Aviation Safety Regulations 1998, empowers the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) concerning specific types of aircraft or aeronautical products, with the overarching goal of ensuring the safety of air navigation. This legislative framework applies to entities and individuals involved in the operation, maintenance, and manufacture of aircraft within Australia, including aircraft owners, operators, and maintenance service providers. The geographic scope of the Act is national, with CASA acting as Australia’s national airworthiness authority responsible for implementing ADs in accordance with international obligations under the Convention on International Civil Aviation. The Act does not provide specific exclusions or thresholds but mandates that CASA, as the national airworthiness authority, must respond to ADs issued by the State of Design, such as the United States Federal Aviation Administration (FAA) for Boeing 737 models, by issuing corresponding Australian ADs. Furthermore, ADs are considered legislative instruments under the Legislative Instruments Act 2003 and do not require public consultation or a Regulatory Impact Statement.
Key Provisions
The Civil Aviation Act 1988, in conjunction with the Civil Aviation Safety Regulations 1998, establishes the framework through which airworthiness directives (ADs) are issued to ensure the safety of air navigation. Section 98 of the Civil Aviation Act 1988 empowers the Governor-General to make regulations necessary for air safety, while regulation 39.001 of the Civil Aviation Safety Regulations 1998 allows the Civil Aviation Safety Authority (CASA) to issue ADs for specific types of aircraft or aeronautical products. These ADs, as outlined in subregulation 39.001(5), are considered disallowable instruments under section 46A of the Acts Interpretation Act 1901 and, as such, are legislative instruments according to section 6 of the Legislative Instruments Act 2003.
Under these regulations, the State of Design of an aircraft type holds the primary responsibility for ensuring the continuing airworthiness of that type, as stipulated in Annex 8 to the Convention on International Civil Aviation. This entails providing necessary information to States of Registry to maintain airworthiness. The State of Registry, in turn, is tasked with developing or adopting requirements to ensure the continuing airworthiness of aircraft registered within its jurisdiction. When an AD is issued by a State of Design, CASA must evaluate this information and, if deemed necessary, issue an Australian AD to mandate the requirements of the State of Design. This ensures that Australian registered aircraft comply with international safety standards.
The obligations imposed by these provisions require CASA to closely monitor and respond to ADs issued by the States of Design, particularly those that impact aircraft registered in Australia. CASA must assess these directives to determine their applicability and necessity within the Australian context, and then issue corresponding Australian ADs to enforce compliance. For example, in response to the US Federal Aviation Administration's (FAA) AD 98-14-09 for Boeing 737 model aircraft, CASA issued Australian AD/B737/258, which became effective on 22 December 2005. This process is driven by international obligations under the Convention on International Civil Aviation and does not typically require public consultation or a Regulatory Impact Statement.
Non-compliance with these airworthiness directives can lead to significant legal consequences. Under the Civil Aviation Act 1988, violations of ADs can result in both civil and criminal penalties. Civil penalties may include fines and other monetary sanctions, while criminal penalties can include imprisonment. The exact penalties depend on the severity and nature of the violation but are intended to ensure strict adherence to air safety standards. Failure to comply with ADs can compromise the safety of air navigation, leading to severe repercussions for individuals and entities involved in civil aviation.
