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, the Civil Aviation Safety Authority (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.

CASA or its predecessors issued AD/AS 355/15 Amdt 1 affecting Eurocopter AS355 helicopters.  CASA has reviewed this AD and as a result has cancelled it.  The cancellation will become effective on 30 July 2009.  No replacement AD is required.

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 is the primary legislation governing aviation safety in Australia, enacted to ensure the safety of air navigation and the continuing airworthiness of aircraft. The Act empowers the Governor-General to make regulations under section 98, with regulation 39.001 specifically enabling the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for kinds of aircraft or aeronautical products. These ADs, as disallowable instruments under section 46A of the Acts Interpretation Act 1901, are legislative instruments that play a critical role in maintaining airworthiness in alignment with international standards set forth in Annex 8 of the Convention on International Civil Aviation. The State of Design is responsible for the continuing airworthiness of aircraft types, while the State of Registry must implement necessary requirements to ensure the continuing airworthiness of individual aircraft. CASA has exercised its authority to issue and subsequently cancel certain ADs, such as AD/AS 355/15 Amdt 1 affecting Eurocopter AS355 helicopters, in accordance with Australia's international obligations and domestic regulatory framework.

Scope and Application

The Civil Aviation Act 1988, as supplemented by the Civil Aviation Safety Regulations 1998, provides the legal framework within which the Civil Aviation Safety Authority (CASA) can issue airworthiness directives (ADs) to ensure the safety of air navigation. These directives are legislative instruments issued under the authority of the Governor-General and apply to specific kinds of aircraft or aeronautical products to maintain their airworthiness. The geographic reach of these regulations is national, extending to all aircraft and aeronautical products registered in Australia, in compliance with international standards set by the Convention on International Civil Aviation, particularly Annex 8. The State of Design holds primary responsibility for ensuring the continuing airworthiness of an aircraft type, while the State of Registry, which in this case is Australia, must implement the necessary requirements to ensure the airworthiness of individual aircraft registered within its jurisdiction. The ADs are intended to provide necessary information for maintaining safety standards, and their issuance and cancellation are conducted in accordance with established regulatory processes without the need for public consultation or a Regulatory Impact Statement. The specific AD/AS 355/15 Amdt 1 affecting Eurocopter AS355 helicopters, which has been cancelled by CASA, exemplifies this regulatory approach and highlights the importance of adhering to international obligations in national regulatory practices.

Key Provisions

The key provision of this legislation is the issuance of airworthiness directives (ADs) by the Civil Aviation Safety Authority (CASA), which are legislative instruments under regulation 39.001 of the Civil Aviation Safety Regulations 1998 (subsection 39.001(5)). These ADs are critical for ensuring the continuing airworthiness of aircraft, as mandated by Annex 8 to the Convention on International Civil Aviation, where the State of Design has the overarching responsibility for maintaining airworthiness, while the State of Registry must ensure the airworthiness of individual aircraft. Specifically, section 98 of the Civil Aviation Act 1988 empowers the Governor-General to make regulations for the safety of air navigation, and regulation 39.001 allows CASA to issue ADs for kinds of aircraft or aeronautical products. The obligations imposed by this Act on the parties involved are primarily centred on ensuring compliance with the ADs issued by CASA. The State of Design must provide necessary information to ensure the continuing airworthiness of aircraft types to States of Registry, while the State of Registry must develop or adopt requirements to ensure the airworthiness of individual aircraft. This means that both the State of Design and the State of Registry have a responsibility to maintain airworthiness through compliance with ADs. CASA, as the regulatory authority, has the obligation to review and issue ADs as necessary, and in this instance, CASA has reviewed and subsequently cancelled a particular AD for Eurocopter AS355 helicopters, effective from 30 July 2009. In terms of consequences for breach, the Act does not explicitly state offences or penalties for non-compliance with ADs. However, the overarching principle is that failure to comply with ADs can lead to significant safety risks, potentially resulting in regulatory action by CASA. While specific penalties are not detailed in the provided text, non-compliance with safety regulations can lead to enforcement actions, including fines, suspension or revocation of airworthiness certificates, and other administrative or legal penalties. Given the critical nature of air safety, the consequences for non-compliance can be severe, impacting both the operators of the aircraft and the authority responsible for regulatory oversight.
