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.
CASA issued AD/BEECH 50/32, affecting Beech 50 model aircraft in 1984. CASA has reviewed this AD and as a result has decided to cancel it. The cancellation will become effective on 13 March 2008. No replacement AD is required, as the original unsafe condition no longer exists.
No consultation with the Australian public has taken place on this AD cancellation, because the cancellation results in a reduction of the regulatory burden. 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, enacted to regulate civil aviation within Australia, addresses the overarching need for safety in air navigation. This Act empowers the Governor-General to create regulations that serve the interests of aviation safety. Under this framework, the Civil Aviation Safety Regulations 1998 were established, which permit the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific aircraft types and aeronautical products. These directives are integral to maintaining the continuing airworthiness of aircraft, aligning with international standards set by the International Civil Aviation Organization (ICAO). The policy objective is to ensure that aircraft registered in Australia meet necessary safety standards, thereby protecting public safety in air travel. The process of issuing and cancelling ADs, such as the recent cancellation of AD/BEECH 50/32 affecting Beech 50 model aircraft, is carried out by CASA, reflecting their role as the national airworthiness authority. This legislative instrument, while crucial for aviation safety, operates within a regulatory framework that also seeks to minimise unnecessary burdens on the public and stakeholders.
Scope and Application
The Civil Aviation Act 1988 and Civil Aviation Safety Regulations 1998 provide the framework under which airworthiness directives (ADs) are issued in Australia. The Act applies to entities such as the Civil Aviation Safety Authority (CASA), which is responsible for ensuring the safety of air navigation. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 empowers CASA to issue ADs for specific types of aircraft or aeronautical products to maintain their airworthiness. These directives are legislative instruments and, as such, are subject to disallowance under the Acts Interpretation Act 1901 and must comply with the Legislative Instruments Act 2003. The ADs are issued in accordance with international standards outlined in Annex 8 to the Convention on International Civil Aviation, which places the responsibility of continuing airworthiness on the State of Design and State of Registry. CASA, as the national airworthiness authority for Australia, is mandated to assess information from the State of Design and issue corresponding ADs as necessary. The cancellation of an AD, such as AD/BEECH 50/32 for Beech 50 model aircraft, is carried out by CASA when the unsafe conditions that prompted the directive no longer exist, without the necessity for public consultation or a Regulatory Impact Statement, as determined by the Office of Best Practice Regulation. The AD cancellation is executed by the Manager, Airframes in the Airworthiness Engineering Branch on behalf of CASA, in accordance with the provisions of the Civil Aviation Act 1988.
Key Provisions
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 outline the processes and requirements for the issuance and management of airworthiness directives (ADs). Section 98 of the Civil Aviation Act 1988 allows the Governor-General to make regulations concerning the safety of air navigation, while regulation 39.001 of the Civil Aviation Safety Regulations 1998 empowers the Civil Aviation Safety Authority (CASA) to issue ADs for specific types of aircraft or aeronautical products. These ADs are legislative instruments under the Legislative Instruments Act 2003, as they are disallowable instruments under section 46A of the Acts Interpretation Act 1901.
The obligations placed upon entities by these provisions are multifaceted. Firstly, the State of Design is responsible for ensuring the continuing airworthiness of an aircraft type and must provide necessary information to States of Registry, as outlined in Annex 8 to the Convention on International Civil Aviation. Secondly, the State of Registry, which in Australia is CASA, must assess this information and, if necessary, issue an AD to enforce the requirements of the State of Design. For example, CASA issued AD/BEECH 50/32 for Beech 50 model aircraft in 1984, but has since reviewed and decided to cancel it due to the resolution of the original unsafe condition.
There are consequences for non-compliance with the ADs. The Civil Aviation Act 1988 stipulates that failure to comply with an AD can result in civil and criminal penalties. Civil penalties can include fines and other financial penalties, while criminal penalties may involve imprisonment. The specific penalties depend on the severity of the non-compliance and the discretion of the court. The issuing authority, CASA, has the power to enforce these directives, and non-compliance can lead to significant legal repercussions for individuals and entities involved in aviation operations.
