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.
Transport Canada has issued AD CF-98-29 affecting Bell 430 model helicopters. Canada is the State of Design for this type. CASA has assessed this AD and has issued Australian AD/BELL 430/8, which will become effective on 26 October 2006.
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 was enacted to regulate the safety of civil aviation within Australia, ensuring the safe operation of aircraft and the protection of the public. The Act empowers the Governor-General to make regulations for the purposes of the Act and in the interests of the safety of air navigation. In this context, the Civil Aviation Safety Regulations 1998, under regulation 39.001, allow the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. These ADs serve as legislative instruments, disallowable under the Acts Interpretation Act 1901, and play a crucial role in maintaining the continuing airworthiness of aircraft as mandated by Annex 8 to the Convention on International Civil Aviation. The State of Registry, including Australia, is responsible for ensuring the airworthiness of individual aircraft, and when a State of Design issues an AD, CASA must assess and, if appropriate, issue an Australian AD to mandate the requirements. This legislative framework ensures that Australia complies with international standards and obligations concerning aircraft safety.
Scope and Application
The Civil Aviation Act 1988, along with the Civil Aviation Safety Regulations 1998, establishes a framework for ensuring the safety of air navigation in Australia, and includes provisions for the issuance of airworthiness directives (ADs) by the Civil Aviation Safety Authority (CASA). ADs are legislative instruments made under regulation 39.001 of the Civil Aviation Safety Regulations, and serve as a mechanism for enforcing continuing airworthiness of aircraft types, as per Annex 8 of the Convention on International Civil Aviation. The State of Design, which is the country responsible for the design of the aircraft, is tasked with providing necessary information to ensure continuing airworthiness, and ADs are the primary means by which this information is communicated. Australia, as a State of Registry for aircraft designed by other countries, must adopt these ADs or issue its own as necessary to maintain airworthiness standards. The issuance of ADs is a regulatory function exercised by CASA, and they are subject to disallowance under the Acts Interpretation Act 1901, with oversight by the Office of Regulatory Review ensuring compliance with legislative processes. ADs issued in response to international directives do not require public consultation, as they are mandated by international obligations.
Key Provisions
The Civil Aviation Act 1988, specifically section 98, empowers the Governor-General to create regulations aimed at enhancing air navigation safety. In line with this provision, regulation 39.001 of the Civil Aviation Safety Regulations 1998 allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) concerning types of aircraft or aeronautical products. These ADs, as outlined in subregulation 39.001(5), are considered disallowable instruments under section 46A of the Acts Interpretation Act 1901, thereby making them legislative instruments as per section 6 of the Legislative Instruments Act 2003.
These airworthiness directives play a crucial role in ensuring the continued safety of aircraft by providing necessary information to states responsible for the ongoing airworthiness of individual aircraft types. According to Annex 8 of the Convention on International Civil Aviation, the State of Design holds the primary responsibility for maintaining an aircraft type's airworthiness, while the State of Registry is tasked with ensuring the airworthiness of specific aircraft registered within its jurisdiction. When a State of Design issues an AD, such as AD CF-98-29 from Transport Canada concerning Bell 430 model helicopters, CASA, as Australia's national airworthiness authority, must evaluate the information and, if necessary, issue a corresponding Australian AD. This was the case with AD/BELL 430/8, which CASA issued in response to the Canadian AD and which will take effect on 26 October 2006.
Entities governed by the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 are required to adhere to the obligations imposed by the ADs issued by CASA. These obligations include ensuring compliance with the ADs, which mandate specific maintenance, repair, or alteration procedures to maintain airworthiness. The State of Registry and aircraft operators must implement the directives to ensure the safety and airworthiness of the aircraft. Additionally, CASA must assess any foreign ADs issued by the State of Design and determine their applicability to aircraft registered in Australia.
Failure to comply with the airworthiness directives can result in serious consequences. While specific offences and penalties are not detailed in the provided text, non-compliance with ADs can generally lead to civil and criminal penalties, including fines and imprisonment, as stipulated by other relevant sections of the Civil Aviation Act 1988. The severity of the penalties may depend on the nature and extent of the non-compliance and any resulting safety risks. CASA has the authority to enforce these regulations and take appropriate action against those who fail to comply with the issued directives.
