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-2004-19 affecting Bombardier DHC-8 model aircraft. Canada is the State of Design for this type. CASA has assessed this AD and has issued Australian AD/DHC-8/127, which will become effective on 31 August 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, enacted by the Commonwealth Parliament, establishes the legislative framework for civil aviation in Australia, with a primary focus on ensuring the safety of air navigation. Section 98 of the Act empowers the Governor-General to make regulations necessary for the safety of air navigation, and regulation 39.001 of the Civil Aviation Safety Regulations 1998 specifically allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives for certain types of aircraft or aeronautical products. This legislative provision addresses the need for a robust system to ensure the continuing airworthiness of aircraft and aeronautical products, aligning with Australia’s international obligations under Annex 8 to the Convention on International Civil Aviation. CASA, as Australia’s national airworthiness authority, has the responsibility to issue these directives when required, based on assessments of directives issued by the State of Design and in accordance with international standards.
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) that mandate safety standards for aircraft and aeronautical products. These regulations are designed to ensure the continuing airworthiness of aircraft registered in Australia, in alignment with international standards set forth by the Convention on International Civil Aviation. ADs serve as legislative instruments and are enforceable under Australian law. The application of these directives is broad, encompassing all aircraft and aeronautical products registered in Australia, as well as any aircraft or products that are manufactured in or imported into Australia. The ADs are issued in response to findings or recommendations made by the State of Design or other contracting states under the Convention on International Civil Aviation. CASA, as Australia's national airworthiness authority, has the responsibility to assess and, if necessary, mandate these directives for aircraft registered in Australia. The issuance of ADs is governed by the regulatory framework and does not typically require consultation with the Australian public or a Regulatory Impact Statement, given their alignment with international safety standards and obligations.
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). Section 98 of the Act allows the Governor-General to make regulations for the safety of air navigation, while regulation 39.001 of the Regulations empowers the Civil Aviation Safety Authority (CASA) to issue ADs for certain kinds of aircraft or aeronautical products. Subregulation 39.001(5) classifies an AD as a disallowable instrument under the Acts Interpretation Act 1901, and subsequently, as a legislative instrument under the Legislative Instruments Act 2003. These provisions ensure that ADs are issued in a legally binding manner, with the aim of maintaining the safety standards of aircraft operating in Australia.
The obligations imposed by the Act and the Regulations on the parties or entities they govern are primarily centred around the maintenance of airworthiness. The State of Design, which is the country where the aircraft type is designed, has the responsibility to provide necessary information to ensure the continuing airworthiness of the aircraft type. This is mandated under Annex 8 to the Convention on International Civil Aviation. The State of Registry, which is the country where the aircraft is registered, must develop or adopt requirements to ensure the continuing airworthiness of the aircraft registered within its jurisdiction. CASA, as Australia’s national airworthiness authority, must assess any ADs issued by the State of Design and, if appropriate, issue corresponding Australian ADs to mandate the necessary requirements. These obligations ensure that both the designers and operators of aircraft maintain the required safety standards.
The Act and the Regulations also outline specific consequences for breaches related to ADs. While the text does not detail specific offences or penalties for non-compliance with ADs, it is understood that failure to comply with an AD could lead to civil or criminal consequences. This is because ADs are legally binding instruments designed to ensure the safety of air navigation. The maximum penalties for non-compliance would depend on the severity of the breach and the specific regulations under which the breach is assessed. However, it is clear that adherence to ADs is crucial, as non-compliance could result in significant legal and safety repercussions. The importance of compliance is underscored by the international obligations and the role of CASA in enforcing these directives to maintain the highest safety standards in Australian aviation.
