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/AC/18 affecting Twin Aero Commander 500, 560E and 680E aircraft models. CASA has assessed this AD and as a result has cancelled Australian AD/AC/18. The cancellation will become effective on 31 July 2008. 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 Manager, Systems and New Technologies, Manager, Airframe and Structures, 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 established to ensure the safety and efficiency of civil aviation within Australia. It provides a legislative framework for regulating air navigation, aircraft operations, and the safety standards of aviation activities. The Act empowers the Governor-General to make regulations that promote air navigation safety, with specific provisions for issuing airworthiness directives (ADs) through the Civil Aviation Safety Regulations 1998. These ADs, which are legislative instruments, are integral to ensuring the continuing airworthiness of aircraft and aeronautical products, aligning with international standards set by the International Civil Aviation Organization (ICAO). The Civil Aviation Safety Authority (CASA) operates as the national airworthiness authority, responsible for assessing and issuing ADs that mandate compliance with airworthiness requirements. The policy objective of these regulations is to maintain and enhance the safety of air navigation through stringent oversight and continuous compliance with international and national standards.
Scope and Application
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 together provide the legislative framework for the regulation of civil aviation safety in Australia, with the Civil Aviation Safety Authority (CASA) being the national airworthiness authority responsible for the implementation of these regulations. Under the authority granted by the Civil Aviation Act 1988, CASA can issue airworthiness directives (ADs) that mandate safety requirements for specific types of aircraft or aeronautical products, which are legislative instruments subject to disallowance. The ADs are aligned with the standards set by the International Civil Aviation Organization (ICAO) and are intended to ensure the continuing airworthiness of aircraft registered in Australia. In accordance with international obligations under the Convention on International Civil Aviation, the State of Design is responsible for the ongoing airworthiness of an aircraft type, while the State of Registry, in this case CASA, must enforce any ADs issued by the State of Design. The AD/AC/18, which affected Twin Aero Commander 500, 560E, and 680E aircraft models, has been cancelled by CASA as the unsafe conditions it addressed no longer exist, without the need for public consultation or a Regulatory Impact Statement. This cancellation is effective from 31 July 2008 and does not require a replacement AD.
Key Provisions
The Civil Aviation Act 1988, along with the Civil Aviation Safety Regulations 1998, provides a framework for ensuring the safety of air navigation in Australia. Section 98 of the Act allows the Governor-General to make regulations for the purposes of the Act, with a focus on safety. Under regulation 39.001, the Civil Aviation Safety Authority (CASA) can issue airworthiness directives (ADs) for certain types of aircraft or aeronautical products. An AD is a legislative instrument, which means it has legal standing and must be followed by those it governs. The authority to issue ADs is based on international standards set out in Annex 8 to the Convention on International Civil Aviation.
The obligations under these regulations are primarily centred on ensuring the continuing airworthiness of aircraft. The State of Design, which is the country where an aircraft type is designed, holds overall responsibility for its continuing airworthiness and must provide necessary information to States of Registry. The State of Registry, in this case CASA, is responsible for ensuring that individual aircraft meet airworthiness standards. When an AD is issued by a State of Design, CASA must evaluate the information and, if necessary, issue an Australian AD to enforce the requirements. This process ensures that aircraft registered in Australia meet international safety standards.
Breach of the obligations or non-compliance with the ADs can lead to serious consequences. Although specific offences, penalties, or civil and criminal consequences are not detailed in the provided text, generally speaking, failing to comply with airworthiness directives can result in severe penalties under the Civil Aviation Act 1988. Such penalties can include fines and, in some cases, criminal charges. It is important for operators and owners of aircraft to adhere strictly to ADs to avoid these consequences and ensure the safety of air navigation. The authority to issue and enforce ADs is a critical tool for maintaining high safety standards in civil aviation.
