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 Civil Aviation Safety Authority or its predecessors issued AD/DHC-1/9 affecting De Havilland DHC-1 (Chipmunk) model aeroplanes. CASA has assessed this AD and as a result has cancelled Australian AD/DHC-1/9. The cancellation will become effective on 23 October 2008. No replacement AD is required, as the unsafe condition no longer exists.
As this AD has been cancelled because of Australia’s obligations under the Convention on International Civil Aviation, no consultation with the Australian public has taken place on this AD cancellation. 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, Airframe and 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 and efficiency of civil aviation in Australia, as well as for related matters. This Act empowers the Governor-General to make regulations that serve the interests of air navigation safety. One such regulation is the Civil Aviation Safety Regulations 1998, which allow the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for certain types of aircraft and aeronautical products. The ADs, which are legislative instruments, play a crucial role in ensuring the continuing airworthiness of aircraft types and are issued by most International Civil Aviation Organization (ICAO) Contracting States, in line with Annex 8 of the Convention on International Civil Aviation. The Act also addresses the responsibilities of both the State of Design and the State of Registry in ensuring the airworthiness of aircraft types. The cancellation of Australian AD/DHC-1/9 for De Havilland DHC-1 (Chipmunk) model aeroplanes, effective 23 October 2008, was made by the Manager, Airframe and Structures, in the Airworthiness Engineering Group, on behalf of CASA, in accordance with the Act. As this cancellation is due to Australia's obligations under the Convention on International Civil Aviation, no consultation with the Australian public has taken place, and the Office of Best Practice Regulation has determined that ADs do not require a Regulatory Impact Statement.
Scope and Application
The Civil Aviation Act 1988, supported by the Civil Aviation Safety Regulations 1998, establishes the framework within which airworthiness directives (ADs) are issued and managed in Australia. Under this legislation, the Civil Aviation Safety Authority (CASA) is empowered to issue ADs for specific types of aircraft or aeronautical products, which are considered legislative instruments as per the Legislative Instruments Act 2003. This regulatory framework applies to all aircraft registered within Australia, ensuring that the State of Registry adheres to the continuing airworthiness requirements set forth by the State of Design, as mandated by Annex 8 to the Convention on International Civil Aviation. CASA’s role as the national airworthiness authority includes the assessment of international ADs and the issuance of corresponding Australian ADs to ensure compliance with safety standards. The legislative process for ADs does not require public consultation or a Regulatory Impact Statement, reflecting their technical and safety-focused nature. Any AD issued by CASA is managed under the oversight of the Manager, Airframe and Structures, within the Airworthiness Engineering Group, ensuring adherence to the legislative mandates of the Civil Aviation Act 1988.
Key Provisions
The Civil Aviation Act 1988 (section 98) and the Civil Aviation Safety Regulations 1998 (regulation 39.001) provide the legislative foundation for the issuance of airworthiness directives (ADs) by the Civil Aviation Safety Authority (CASA). These directives are critical for ensuring the ongoing airworthiness of aircraft types and aeronautical products. An AD is a legislative instrument under section 46A of the Acts Interpretation Act 1901, and it falls within the scope of the Legislative Instruments Act 2003. The State of Design, typically the country where the aircraft is designed, bears the primary responsibility for ensuring the continuing airworthiness of an aircraft type, and must provide necessary information to States of Registry, such as Australia. CASA, as Australia's national airworthiness authority, must assess the ADs issued by the State of Design and may issue corresponding Australian ADs to enforce the requirements.
The obligations imposed by the Civil Aviation Safety Regulations 1998 include the requirement for CASA to assess and potentially issue Australian ADs when an AD is issued by the State of Design. This ensures that the continuing airworthiness of aircraft registered in Australia is maintained in accordance with international standards. The State of Registry, such as Australia, must also develop or adopt requirements to ensure the continuing airworthiness of aircraft within its jurisdiction. This involves working closely with CASA to implement and enforce ADs as necessary. The cooperation between the State of Design and the State of Registry is crucial in maintaining global aviation safety standards.
Non-compliance with ADs can lead to serious consequences. For instance, if an aircraft operator fails to adhere to an AD, the aircraft may be deemed unairworthy, resulting in the grounding of the aircraft. This could have significant ramifications for both the operator and passengers. From a legal perspective, failure to comply with ADs can result in civil penalties, including fines, as well as criminal penalties for more serious breaches. The specific penalties depend on the severity of the breach and the jurisdiction under which CASA operates. However, the overarching aim of these provisions is to ensure that all aircraft maintain the highest safety standards, thereby protecting the public and maintaining the integrity of the aviation industry.
