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 Austrian CAA has issued AD A-2005-003 affecting Diamond DA42 model aircraft. Austria is the State of Design for this type. CASA has assessed this AD and has issued Australian AD/DA42/4, which will become effective on 5 June 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 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, serves to regulate civil aviation within Australia, with a primary focus on ensuring the safety of air navigation. The Act empowers the Governor-General to create regulations aimed at maintaining the safety of air navigation, which includes the issuance of airworthiness directives (ADs) by the Civil Aviation Safety Authority (CASA) under regulation 39.001 of the Civil Aviation Safety Regulations 1998. The ADs are legislative instruments that comply with the requirements of the Legislative Instruments Act 2003. In line with international standards set forth by the Convention on International Civil Aviation, particularly Annex 8, the State of Design has the responsibility for the continuing airworthiness of an aircraft type, necessitating the provision of necessary information to the States of Registry. CASA, as Australia’s national airworthiness authority, is tasked with assessing these directives and, if deemed appropriate, issuing corresponding Australian ADs to enforce the requirements of the State of Design.
Scope and Application
The Civil Aviation Safety Regulations 1998, pursuant to the Civil Aviation Act 1988, empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products, ensuring the safety of air navigation as per section 98 of the Act. These ADs, which are legislative instruments as defined by the Acts Interpretation Act 1901, are instrumental in maintaining the continuing airworthiness of aircraft types. The ADs must be aligned with the obligations under the Convention on International Civil Aviation, particularly Annex 8, which designates the State of Design as responsible for providing necessary information to ensure an aircraft type’s continuing airworthiness. Australia, as the State of Registry for certain aircraft types, is obliged to issue corresponding ADs upon assessing those issued by the State of Design, such as AD/DA42/4 issued in response to Austria's AD A-2005-003 for the Diamond DA42 model aircraft. This process does not involve public consultation or require a Regulatory Impact Statement, as determined by the Office of Best Practice Regulation. CASA issues these ADs under the authority granted by the Act, ensuring compliance with international standards and maintaining the safety standards within the Australian airspace.
Key Provisions
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 lay out the framework for ensuring the safety and airworthiness of aircraft operating in Australian airspace. Section 98 of the Act allows the Governor-General to make regulations for the safety of air navigation, and regulation 39.001 of the Civil Aviation Safety Regulations 1998 empowers CASA to issue airworthiness directives (ADs) for specific kinds of aircraft or aeronautical products. An AD is a legislative instrument, as per section 46A of the Acts Interpretation Act 1901, and it is made under the authority granted by section 84A(2) of the Civil Aviation Act 1988. This legislative process ensures that ADs are binding and enforceable.
The obligations imposed by these regulations are significant. The State of Design, which is responsible for the initial airworthiness of an aircraft type, must provide all necessary information to ensure the continuing airworthiness of that type to the States of Registry, including Australia. In this case, Austria, as the State of Design for the Diamond DA42 model aircraft, issued AD A-2005-003. CASA, as Australia’s national airworthiness authority, is required to assess this information and issue a corresponding Australian AD if necessary. This process ensures that Australian aircraft meet international safety standards and that Australian aviation authorities are accountable for enforcing these standards domestically.
Failure to comply with an AD can have serious legal consequences. Under the Civil Aviation Act 1988, non-compliance with an AD can result in civil penalties. Specifically, section 201 of the Act allows for fines of up to $22,200 for individuals and $111,000 for bodies corporate for each instance of non-compliance. Furthermore, operating an aircraft that does not comply with an AD can lead to criminal charges under section 202, which carries a penalty of up to 200 penalty units, currently amounting to approximately $33,000. These penalties underscore the importance of adhering to ADs to maintain the highest safety standards in aviation.
Additionally, the regulations do not require consultation with the public or a Regulatory Impact Statement for ADs, as determined by the Office of Best Practice Regulation. This decision is based on the international obligations under the Convention on International Civil Aviation and the specific nature of ADs, which are technical and safety-focused rather than broad policy measures. The streamlined process ensures that critical safety information can be disseminated and enforced without undue delay, protecting the public and maintaining the integrity of the aviation safety framework.
