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 2008-21-08 affecting Air Tractor 402 model aircraft. The USA is the State of Design for this type. CASA has assessed this AD and has issued Australian AD/AT/30, which will become effective on 18 December 2008.
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 provide for the safety of air navigation and other aspects of civil aviation within Australia. The Act grants the Governor-General the authority to make regulations necessary for the safety of air navigation. One of the key regulatory tools provided for under the Act is the issuance of airworthiness directives (ADs) by the Civil Aviation Safety Authority (CASA) to ensure the continuing airworthiness of aircraft. These ADs are mandated by regulation 39.001 of the Civil Aviation Safety Regulations 1998 and are considered legislative instruments under the Legislative Instruments Act 2003. The issuance of ADs is driven by international obligations under the Convention on International Civil Aviation, particularly Annex 8, which assigns the State of Design the responsibility for the continuing airworthiness of aircraft types and requires States of Registry to implement necessary measures to maintain airworthiness. CASA, as Australia’s national airworthiness authority, is tasked with assessing ADs issued by the State of Design and, where appropriate, issuing corresponding Australian ADs to comply with international standards and ensure the safety of aircraft registered in Australia.
Scope and Application
The Civil Aviation Act 1988, as supplemented by the Civil Aviation Safety Regulations 1998, grants the Civil Aviation Safety Authority (CASA) the authority to issue airworthiness directives (ADs) concerning specific types of aircraft or aeronautical products. This authority is exercised to ensure the safety of air navigation and aligns with the obligations under the Convention on International Civil Aviation, particularly concerning the continuing airworthiness of aircraft. The State of Registry, which in the case of Australia is CASA, holds the responsibility for the ongoing airworthiness of aircraft registered within its jurisdiction. Consequently, when a State of Design, such as the United States for the Air Tractor 402 model aircraft, issues an AD, CASA evaluates this information and, if necessary, issues a corresponding Australian AD to enforce the requirements stipulated by the State of Design. This process is governed by regulation 39.001 of the Civil Aviation Safety Regulations 1998 and is recognised as a legislative instrument under the Acts Interpretation Act 1901. Notably, such directives do not necessitate public consultation or a Regulatory Impact Statement, as determined by the Office of Best Practice Regulation.
Key Provisions
The Civil Aviation Act 1988 provides the framework for ensuring the safety of air navigation, with regulation 39.001 of the Civil Aviation Safety Regulations 1998 empowering the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. This authority is exercised under the auspices of section 98 of the Act, ensuring that the directives align with the overarching goal of maintaining the safety of air navigation. An airworthiness directive, as per subregulation 39.001(5), is classified as a disallowable instrument under section 46A of the Acts Interpretation Act 1901 and is a legislative instrument in accordance with section 6 of the Legislative Instruments Act 2003. These directives are essential tools in the maintenance of continuing airworthiness as outlined in Annex 8 to the Convention on International Civil Aviation, where the State of Design holds responsibility for an aircraft type’s continuing airworthiness and must provide necessary information to the States of Registry.
Entities governed by these regulations, such as CASA, are tasked with the responsibility of ensuring the continuing airworthiness of aircraft registered in Australia. When a State of Design issues an AD, CASA must evaluate the provided information and, if necessary, issue an Australian AD to enforce the requirements set by the State of Design. This process is mandatory and ensures that Australian-registered aircraft meet international safety standards. The State of Registry is also obligated to develop or adopt requirements that ensure the ongoing airworthiness of aircraft within its jurisdiction, reinforcing the collaborative nature of international aviation safety standards.
Breaches of the requirements set out in airworthiness directives can lead to significant legal consequences. Although specific offences and penalties are not detailed within the text, it is understood that non-compliance with ADs could result in severe repercussions, including potential civil or criminal penalties. These could encompass fines, imprisonment, or other punitive measures, depending on the severity and impact of the non-compliance on aviation safety. The legislative nature of ADs underscores their importance, and any failure to adhere to these directives can jeopardise the safety and regulatory compliance of aviation operations in Australia.
