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 2008-13-21 affecting Boeing 767 model aircraft. The United States is the State of Design for this type. CASA has assessed this AD and has issued Australian AD/B767/245, which will become effective on 23 October 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 Acting Manager, Systems and New Technologies in the Airworthiness Engineering Group, 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 safety and efficiency in air navigation. The Act empowers the Governor-General to create regulations for air navigation safety, as seen in the Civil Aviation Safety Regulations 1998. These regulations permit the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for aircraft types and aeronautical products. ADs are a crucial mechanism for maintaining the continuing airworthiness of aircraft and are issued by the State of Design or Registry, in accordance with the Convention on International Civil Aviation. CASA, as Australia’s national airworthiness authority, is responsible for assessing and, if necessary, issuing Australian ADs in response to directives from the relevant State of Design. This legislative framework facilitates compliance with international standards and ensures that Australian aviation remains safe and reliable.
Scope and Application
The Civil Aviation Act 1988, supported by the Civil Aviation Safety Regulations 1998, establishes the framework within which airworthiness directives (ADs) are issued to ensure the safety of air navigation in Australia. These regulations empower the Civil Aviation Safety Authority (CASA) to issue ADs for specific types of aircraft or aeronautical products. Notably, these directives are considered disallowable instruments under section 46A of the Acts Interpretation Act 1901, making them legislative instruments in their own right. This process is mandated by Australia’s obligations under Annex 8 to the Convention on International Civil Aviation, which assigns the State of Design overall responsibility for the continuing airworthiness of aircraft types. Consequently, when a State of Design issues an AD, such as the United States Federal Aviation Administration's AD 2008-13-21 for Boeing 767 model aircraft, CASA must assess the information and, if necessary, issue a corresponding Australian AD to enforce the required safety measures. This approach underscores CASA’s role as Australia’s national airworthiness authority and its duty to ensure compliance with international standards.
Key Provisions
The Civil Aviation Act 1988, specifically under section 98, grants the Governor-General the authority to establish regulations aimed at ensuring the safety of air navigation. This foundational provision allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) under regulation 39.001 of the Civil Aviation Safety Regulations 1998. These directives, which pertain to particular types of aircraft or aeronautical products, are mandated to uphold airworthiness standards. According to subregulation 39.001(5), ADs are classified as disallowable instruments under section 46A of the Acts Interpretation Act 1901 and are considered legislative instruments as per section 6 of the Legislative Instruments Act 2003.
Entities governed by the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998, particularly CASA, are obligated to ensure the continuing airworthiness of aircraft registered in Australia. This responsibility includes the assessment and potential issuance of Australian ADs when necessary. The State of Design, such as the United States for Boeing 767 model aircraft, is responsible for providing information and directives to maintain airworthiness, and CASA must act on this information. The State of Registry, CASA in this context, must also develop or adopt requirements to maintain airworthiness, and must comply with ADs issued by the State of Design. The interaction between these states ensures that international safety standards are met and that aircraft are maintained to a high level of safety.
There are specific obligations and requirements imposed by the Act and the Regulations on the parties involved. CASA, as the national airworthiness authority, must rigorously assess any AD issued by a State of Design and determine if an Australian AD is necessary. If so, CASA must issue the appropriate AD to mandate the required actions to maintain airworthiness. The State of Registry must ensure that all aircraft under its purview comply with the issued ADs. Non-compliance with these directives can result in severe consequences, including grounding of aircraft, fines, and potential criminal charges. The ADs themselves are legally binding, and failure to adhere to them can lead to enforcement actions by CASA.
In terms of offences, penalties, and consequences, failure to comply with an airworthiness directive can result in both civil and criminal penalties. Civil penalties may include fines and the grounding of aircraft, while criminal penalties can include imprisonment. The maximum penalties vary depending on the severity of the breach and the specific provisions of the Civil Aviation Act 1988. CASA has the authority to take enforcement actions against any party that fails to comply with an AD, which may include issuing fines, suspending or revoking airworthiness certificates, and initiating criminal proceedings. These measures are designed to ensure that airworthiness standards are upheld and that the safety of air navigation is maintained at all times.
