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-2004-21R3 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 430/1, Amendment 4, which will become effective on 1 June 2008. This AD cancels and replaces the previous issue.
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 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 by the Commonwealth Parliament, establishes the framework for ensuring the safety of air navigation in Australia. To address the need for regulations that ensure the safety of air navigation, the Governor-General has the authority under section 98 of the Act to make regulations for these purposes. Complementing this, the Civil Aviation Safety Regulations 1998 permit the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for types of aircraft or aeronautical products, which are integral to maintaining the continuing airworthiness of aircraft as mandated by Annex 8 of the Convention on International Civil Aviation. This legislative arrangement ensures that Australia meets its international obligations and maintains high safety standards in civil aviation. The policy objective is to safeguard the public by ensuring that all aircraft operating within Australian airspace meet stringent safety standards.
Scope and Application
The Civil Aviation Safety Regulations 1998, under section 39.001, empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. These directives are legislative instruments, as outlined in subregulation 39.001(5) of the Civil Aviation Safety Regulations 1998, and they adhere to the requirements of section 46A of the Acts Interpretation Act 1901. ADs serve as a crucial means of ensuring the continuing airworthiness of aircraft types, as mandated by Annex 8 to the Convention on International Civil Aviation. The State of Design, which in this case is Canada for the Bell 430 model helicopters, holds the primary responsibility for issuing ADs. CASA, acting as Australia's national airworthiness authority, must assess these directives and, if necessary, issue corresponding Australian ADs to enforce the requirements set forth by the State of Design. The issuance of such directives is a direct result of Australia's obligations under the Convention on International Civil Aviation and does not require public consultation or a Regulatory Impact Statement. The AD is issued by the Manager, Airframes in the Airworthiness Engineering Branch, on behalf of CASA, in accordance with subsection 84A(2) of the Civil Aviation Act 1988.
Key Provisions
The Civil Aviation Act 1988 (section 98) empowers the Governor-General to create regulations to ensure the safety of air navigation. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. These ADs are formal legislative instruments as per subregulation 39.001(5) and section 6 of the Legislative Instruments Act 2003. The State of Design, as per Annex 8 of the Convention on International Civil Aviation, bears the responsibility for the continuing airworthiness of an aircraft type, including providing necessary information to the States of Registry. The State of Registry must then develop or adopt requirements to maintain the airworthiness of the aircraft. For instance, CASA, as Australia’s national airworthiness authority, must evaluate any ADs issued by the State of Design and, if necessary, issue corresponding Australian ADs to enforce these requirements.
Under the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998, both the State of Design and the State of Registry have distinct obligations. The State of Design must issue ADs to ensure the safety and continuing airworthiness of the aircraft type, while the State of Registry must implement these ADs by issuing national ADs if necessary. This collaborative approach ensures that all aircraft meet international safety standards. For example, Transport Canada issued AD CF-2004-21R3 for Bell 430 model helicopters, with CASA subsequently issuing Australian AD/BELL 430/1, Amendment 4, effective from 1 June 2008.
Given that ADs are issued in response to international obligations under the Convention on International Civil Aviation and the specific ADs issued by the State of Design, the process does not require public consultation or a Regulatory Impact Statement. The Office of Best Practice Regulation has confirmed that ADs do not necessitate such assessments. This AD was made by the Manager, Airframes in the Airworthiness Engineering Branch on behalf of CASA, in accordance with subsection 84A(2) of the Act.
The consequences of breaching the ADs are significant. Non-compliance with ADs can result in severe penalties, including substantial fines and potential imprisonment. The exact penalties vary depending on the nature and severity of the breach. For example, under the Civil Aviation Act 1988, failure to comply with an AD can result in a fine of up to 10,000 penalty units for individuals and 50,000 penalty units for corporations, along with imprisonment for up to two years for individuals. Such stringent measures underscore the importance of adhering to airworthiness directives to maintain the highest safety standards in aviation.
