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 Civil Aviation Safety Authority or its predecessors issued AD/BEECH 23/12 affecting Beech A23-24 aircraft. CASA has assessed this AD and as a result has cancelled Australian AD/BEECH 23/12. The cancellation will become effective on 20 December 2007. No replacement AD is required, as the unsafe condition no longer exists.
As this AD has been cancelled because of Australia’s obligations under the Convention on International Civil Aviation, no consultation with the Australian public has taken place on this AD cancellation. 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 Branch, on behalf of CASA, in accordance with subsection 84A (2) of the Act.
Overview
The Civil Aviation Act 1988, enacted by the Commonwealth Parliament, was introduced to ensure the safety of air navigation within Australia. This Act empowers the Governor-General to establish regulations for air navigation safety, including the issuance of airworthiness directives (ADs) as per regulation 39.001 of the Civil Aviation Safety Regulations 1998. These ADs, which are legislative instruments, are crucial for maintaining the continuing airworthiness of aircraft in accordance with international standards, particularly as stipulated in Annex 8 of the Convention on International Civil Aviation. The Civil Aviation Safety Authority (CASA) is responsible for issuing and enforcing these ADs in Australia, ensuring that all aircraft meet the necessary safety standards. The authority derives its mandate from the Act and operates under the oversight of the State of Registry for individual aircraft, ensuring compliance with both national and international airworthiness requirements.
Scope and Application
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 govern the issuance of airworthiness directives (ADs) in Australia, ensuring the continuing airworthiness of aircraft registered in Australia. These regulations allow the Civil Aviation Safety Authority (CASA) to issue ADs for specific types of aircraft or aeronautical products, in line with Australia’s obligations under the Convention on International Civil Aviation. ADs are legislative instruments that mandate safety requirements and are typically issued by states to address unsafe conditions identified in aircraft types. The State of Design, where the aircraft was designed, is responsible for issuing initial ADs, while the State of Registry, in this case Australia, is responsible for ensuring that these directives are properly assessed and implemented for aircraft registered within its jurisdiction. CASA, acting as Australia’s national airworthiness authority, must evaluate foreign ADs and issue corresponding Australian ADs if necessary. The cancellation of an AD, such as AD/BEECH 23/12 for Beech A23-24 aircraft, reflects the resolution of the unsafe condition identified, thus no longer requiring regulatory action. This process operates within the framework of international aviation standards and does not typically involve public consultation or the preparation of a Regulatory Impact Statement, as determined by the Office of Best Practice Regulation.
Key Provisions
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) concerning types of aircraft or aeronautical products, as outlined in regulation 39.001(5). An AD is a legislative instrument, which means it has formal legal standing (section 6 of the Legislative Instruments Act 2003). These directives are essential for maintaining the continuing airworthiness of aircraft types, as required by Annex 8 to the Convention on International Civil Aviation. According to this convention, the State of Design must provide necessary information to ensure the airworthiness of a type, and the State of Registry must implement measures to ensure the airworthiness of individual aircraft registered within its jurisdiction. In the context of Australian aviation, CASA, as the national airworthiness authority, is responsible for assessing information from the State of Design and issuing Australian ADs as appropriate. For instance, CASA issued and subsequently cancelled Australian AD/BEECH 23/12 concerning Beech A23-24 aircraft due to the resolution of the unsafe condition it was addressing.
The obligations imposed by the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 require CASA to rigorously assess information from the State of Design. If an AD is necessary, CASA must issue an Australian AD to mandate the required safety measures. This ensures that aircraft on the Australian Register meet the necessary safety standards. In the case of AD/BEECH 23/12, CASA assessed the information from the State of Design and determined that the unsafe condition no longer existed, leading to the cancellation of the directive. Additionally, the State of Registry, through CASA, must ensure that all aircraft registered in Australia comply with these airworthiness directives and related safety regulations.
Failure to comply with airworthiness directives can result in serious consequences. Under the Civil Aviation Act 1988, non-compliance with an AD can lead to civil and criminal penalties. The severity of these penalties depends on the nature and extent of the non-compliance, but they can include fines and imprisonment. The specific penalties are not detailed in the provided text but are typically outlined in the relevant sections of the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998. Ensuring adherence to ADs is critical for maintaining the safety of air navigation and protecting the public from aviation-related risks. CASA's role in issuing, monitoring, and enforcing compliance with these directives is therefore crucial to upholding aviation safety standards in Australia.
