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 2005-21-04 affecting Bell model 47 helicopters. The USA is the State of Design for this type. CASA has assessed this AD and has issued Australian AD/BELL 47/101, which will become effective on 9 November 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, enacted by the Commonwealth Parliament, provides a comprehensive legal framework for the regulation of civil aviation within Australia. It aims to ensure the safety, efficiency and orderly development of civil aviation. In line with this, the Civil Aviation Safety Regulations 1998 were established to further specify the safety requirements for aircraft and aeronautical products. Under section 98 of the Civil Aviation Act 1988, the Governor-General is empowered to make regulations necessary for the safety of air navigation, with regulation 39.001 allowing the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific aircraft types or aeronautical products. These directives are legislative instruments that mandate actions to maintain the airworthiness of aircraft, as outlined in Annex 8 to the Convention on International Civil Aviation. The policy objective of these regulations is to harmonise Australian civil aviation practices with international standards, thereby ensuring the continuing airworthiness of aircraft registered in Australia.
Scope and Application
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 govern the issuance of airworthiness directives (ADs) in Australia, which are designed to maintain the continuing airworthiness of aircraft as mandated by international conventions, particularly Annex 8 to the Convention on International Civil Aviation. Under these regulations, the Civil Aviation Safety Authority (CASA) has the authority to issue ADs for specific kinds of aircraft or aeronautical products. Such directives are considered legislative instruments and are subject to disallowance under the Acts Interpretation Act 1901. The State of Design, which is the country where the aircraft was designed, holds the primary responsibility for the continuing airworthiness of an aircraft type and must provide necessary information to the States of Registry. The State of Registry, in this case CASA, must then assess this information and, if deemed appropriate, issue an Australian AD to enforce the requirements set forth by the State of Design. This process ensures that Australian-registered aircraft comply with international safety standards. For instance, following the issuance of an AD by the US Federal Aviation Administration (FAA) for Bell model 47 helicopters, CASA has assessed and subsequently issued Australian AD/BELL 47/101, which will be effective from 9 November 2005. Given the international nature of these directives, there has been no requirement for public consultation or a Regulatory Impact Statement, and the AD has been issued in accordance with the Civil Aviation Act 1988.
Key Provisions
The key operative sections of the Civil Aviation Safety Regulations 1998, particularly regulation 39.001, allow the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) concerning specific types of aircraft or aeronautical products. An AD is a formal directive issued under the authority of the Civil Aviation Act 1988, and it is considered a legislative instrument, which means it carries the weight of law (sections 39.001 and 6 of the Legislative Instruments Act 2003). These directives are essential for ensuring that aircraft remain airworthy and comply with safety standards. The Civil Aviation Act 1988 provides the legislative foundation, allowing the Governor-General to make regulations in the interests of air navigation safety, and the Civil Aviation Safety Regulations 1998 specify the procedures for issuing ADs.
The obligations imposed by the ADs are primarily on the State of Registry, which is responsible for ensuring the continuing airworthiness of individual aircraft registered within its jurisdiction. For aircraft types designed in other countries, such as the Bell model 47 helicopter designed in the United States, CASA must review and assess the airworthiness directives issued by the State of Design. If deemed necessary, CASA may issue its own ADs to enforce the requirements set forth by the State of Design within the Australian context. This includes ensuring that all stakeholders, such as aircraft operators and maintenance organisations, comply with the ADs to maintain the safety and airworthiness of the aircraft.
Failure to comply with the requirements of an AD can lead to serious legal consequences. While specific offences and penalties are not detailed in the provided text, breaches of aviation regulations generally attract significant penalties under Australian law. For example, non-compliance with ADs could result in fines, imprisonment, or both, depending on the severity of the breach and its impact on safety. In some cases, CASA may also take enforcement actions such as grounding aircraft or revoking airworthiness certificates, which can have severe repercussions for operators and manufacturers. The maximum penalties for such breaches can vary, but they are typically substantial, reflecting the critical nature of maintaining airworthiness and safety standards in aviation.
