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 European Aviation Safety Authority (EASA) has issued AD 2007-0127 affecting Société de Motorisations Aéronautiques SR305-230 model engines. EASA acts on behalf of France, the State of Design for this type. CASA has assessed this AD and has issued Australian AD/SMA/3, which will become effective on 5 July 2007.
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 was enacted to provide a comprehensive legal framework for civil aviation in Australia, aiming to ensure safety and efficiency in air navigation. The Act empowers the Governor-General to make regulations necessary for the safety of air navigation, which includes the issuance of airworthiness directives (ADs) through the Civil Aviation Safety Regulations 1998. These ADs are legislative instruments that mandate specific requirements to ensure the continuing airworthiness of aircraft, reflecting Australia's commitment to international standards under the Convention on International Civil Aviation. In this context, the Civil Aviation Safety Authority (CASA) acts as Australia's national airworthiness authority, responsible for issuing Australian ADs when required by international obligations or assessments of relevant State of Design directives. The policy objective of these regulations is to harmonise with international civil aviation standards, ensuring the safety of aircraft operating in Australian airspace.
Scope and Application
The Civil Aviation Safety Regulations 1998, specifically regulation 39.001, empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) concerning particular types of aircraft or aeronautical products. This authority is exercised to ensure the safety of air navigation in accordance with section 98 of the Civil Aviation Act 1988. The issuance of these ADs is a legislative instrument, as stipulated by section 46A of the Acts Interpretation Act 1901 and section 6 of the Legislative Instruments Act 2003. ADs are essential for maintaining the continuing airworthiness of aircraft types, a responsibility shared by the State of Design and the State of Registry under Annex 8 to the Convention on International Civil Aviation. CASA, as Australia's national airworthiness authority, is tasked with assessing and implementing ADs issued by the State of Design, such as the AD 2007-0127 from the European Aviation Safety Authority (EASA) concerning Société de Motorisations Aéronautiques SR305-230 model engines, which has been translated into the Australian AD/SMA/3 effective from 5 July 2007. Given the international obligations and the nature of ADs, no public consultation or Regulatory Impact Statement is required for their issuance.
Key Provisions
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 establish the framework for issuing airworthiness directives (ADs) to ensure the safety of air navigation. Under section 98 of the Act, the Governor-General can create regulations to support the Act, and regulation 39.001 of the Regulations empowers the Civil Aviation Safety Authority (CASA) to issue ADs for specific types of aircraft or aeronautical products. This regulatory authority is derived from Annex 8 to the Convention on International Civil Aviation, which assigns the State of Design the responsibility for the continuing airworthiness of an aircraft type, and mandates that States of Registry adopt necessary requirements to maintain airworthiness.
The obligations imposed by these provisions require CASA to act on ADs issued by the State of Design. When a State of Design issues an AD, CASA must assess the information provided and, if necessary, issue an Australian AD to enforce the requirements of the State of Design. This ensures that Australian-registered aircraft meet international safety standards. The State of Registry, in this case CASA, must also ensure that any ADs issued are implemented on aircraft registered in Australia. The process of issuing an AD is streamlined, as it does not require public consultation or a Regulatory Impact Statement, given its alignment with international obligations and the urgency of safety concerns.
Failure to comply with an AD can result in significant legal consequences. Under section 84A(2) of the Act, CASA has the authority to enforce compliance, and non-compliance can lead to serious repercussions. While the exact penalties are not specified in the provided text, it is clear that any breach of an AD could lead to enforcement actions by CASA, potentially including fines or other sanctions. These measures are intended to ensure that all parties adhere to the safety requirements mandated by the ADs, thereby maintaining the high safety standards of civil aviation.
Overall, the key provisions of the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 establish a robust framework for the issuance and enforcement of ADs to ensure the safety of aircraft operating in Australia. By aligning with international standards and leveraging the authority of CASA, these provisions ensure that the continuing airworthiness of aircraft is maintained through timely and effective regulatory measures.
