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 2006-08-08 R1 affecting Air Tractor AT-400 series aircraft. The USA is the State of Design for this type. CASA has assessed this AD and has issued Australian AD/AT/27 Amendment 2, which will become effective on 4 June 2009. 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 & Structures in the Airworthiness Engineering Group, on behalf of CASA, in accordance with subsection 84A (2) of the Act.
Overview
The Civil Aviation Act 1988 was enacted to establish a comprehensive framework for the regulation of civil aviation in Australia, ensuring safety and efficiency in the national airspace. One of the key mechanisms under this Act is the issuance of airworthiness directives (ADs) to maintain the safety standards of aircraft. The Civil Aviation Safety Regulations 1998, which were made under the authority of the Act, provide for the creation and implementation of these ADs. The Civil Aviation Safety Authority (CASA), as Australia's national airworthiness authority, is responsible for assessing foreign ADs and issuing corresponding Australian ADs when necessary. This process is mandated by Australia's obligations under the Convention on International Civil Aviation, ensuring that the continuing airworthiness of aircraft on the Australian Register aligns with international standards. The ADs are considered legislative instruments and do not require public consultation or a Regulatory Impact Statement, as they are issued in response to directives from the aircraft's State of Design.
Scope and Application
The Civil Aviation Safety Regulations 1998, under the Civil Aviation Act 1988, empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specified types of aircraft or aeronautical products. These ADs are legislative instruments and play a crucial role in ensuring the continuing airworthiness of aircraft as mandated by international conventions, particularly Annex 8 to the Convention on International Civil Aviation. Each State of Design, such as the United States for the Air Tractor AT-400 series, has the responsibility to issue ADs based on their findings, and CASA, as Australia's national airworthiness authority, must then assess these directives and, if necessary, issue corresponding Australian ADs to enforce the required safety measures. This regulatory framework ensures that Australian aircraft maintain compliance with international safety standards, and while no public consultation is required for these ADs due to their international obligations, they are meticulously reviewed and enforced to safeguard aviation safety within Australia.
Key Provisions
The key operative sections of the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 establish the framework for the issuance of airworthiness directives (ADs) by the Civil Aviation Safety Authority (CASA). Section 98 of the Civil Aviation Act 1988 allows the Governor-General to make regulations for the safety of air navigation, while regulation 39.001 of the Civil Aviation Safety Regulations 1998 specifically empowers CASA to issue ADs for certain kinds of aircraft or aeronautical products. Subregulation 39.001(5) further clarifies that an AD is a disallowable instrument under section 46A of the Acts Interpretation Act 1901 and is therefore a legislative instrument.
The obligations imposed by these provisions on CASA and other relevant parties are significant. CASA, as Australia’s national airworthiness authority, must assess information provided by the State of Design to ensure the continuing airworthiness of aircraft. If an AD is issued by the State of Design, CASA must evaluate this information and, if deemed necessary, issue an Australian AD to mandate the requirements of the State of Design. The State of Registry of an individual aircraft is also responsible for ensuring the continuing airworthiness of that aircraft, which includes complying with any applicable ADs.
The Act and Regulations also outline the consequences for non-compliance with ADs. While the text does not detail specific penalties, non-compliance with ADs can result in significant civil and criminal consequences, including fines and imprisonment. The severity of these penalties underscores the importance of adhering to ADs to maintain the safety standards required by international aviation agreements and domestic regulations. CASA’s role in issuing and enforcing ADs is thus critical in upholding these standards and ensuring the safety of air navigation in Australia.
