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.
CASA issued AD/DAUPHIN/10 affecting Eurocopter SA365 Dauphin helicopters in 1984. CASA has reviewed this AD and as a result has decided to cancel it. The cancellation will become effective on 27 August 2009. No replacement AD is required as the original unsafe condition no longer exists.
No consultation with the Australian public has taken place on this AD cancellation, because the cancellation results in a reduction of the regulatory burden. 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, Initial Airworthiness, in the Airworthiness and Engineering Branch, on behalf of CASA, in accordance with subsection 84A (2) of the Act.
Overview
The Civil Aviation Act 1988, enacted by the Australian Parliament, provides the legal framework for ensuring the safety and efficiency of civil aviation in Australia. This Act empowers the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) under regulation 39.001 of the Civil Aviation Safety Regulations 1998, serving as a legislative instrument aimed at maintaining airworthiness standards. This regulatory approach addresses the need for ongoing oversight and management of aircraft safety issues identified post-certification. CASA's issuance and subsequent cancellation of ADs, such as the case of AD/DAUPHIN/10 affecting Eurocopter SA365 Dauphin helicopters, reflects its role in mitigating safety risks by responding to changes in aircraft conditions or the resolution of identified safety issues. The policy objective behind these regulations is to ensure that all aircraft operating within Australia meet stringent safety standards, thereby protecting the public and enhancing the overall safety of air navigation.
Scope and Application
The Civil Aviation Act 1988, as supplemented by the Civil Aviation Safety Regulations 1998, encompasses a broad scope concerning the regulation and oversight of civil aviation in Australia. Specifically, the Act authorises the issuance of airworthiness directives (ADs) by the Civil Aviation Safety Authority (CASA) to ensure the safety of aircraft and aeronautical products. The application of these regulations extends to all aircraft and aeronautical products within Australian jurisdiction, regardless of whether they are registered in Australia or are foreign-registered aircraft operating within Australian airspace. This regulatory framework is underpinned by the international standards set by Annex 8 to the Convention on International Civil Aviation, which delineates the responsibilities of States of Design and States of Registry in maintaining the airworthiness of aircraft. ADs, as a legislative instrument, are essential tools in enforcing these standards domestically, ensuring that both the State of Registry and aircraft operators adhere to the necessary safety protocols. The Act and its regulations are thus applicable to all entities involved in civil aviation within Australia, including aircraft manufacturers, operators, and regulatory authorities, and they extend to the broader national and international airspace under Australian oversight.
Key Provisions
The key operative sections of the Civil Aviation Act 1988, as applied through the Civil Aviation Safety Regulations 1998, provide that the Civil Aviation Safety Authority (CASA) has the authority to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products under regulation 39.001 (subsection 39.001(5)). These directives are considered disallowable instruments under section 46A of the Acts Interpretation Act 1901, and they constitute legislative instruments as per section 6 of the Legislative Instruments Act 2003. The ADs are a common mechanism for maintaining the continuing airworthiness of aircraft, as outlined in Annex 8 to the Convention on International Civil Aviation. The State of Design, which is the country where the aircraft type is designed, bears the primary responsibility for ensuring the aircraft's continuing airworthiness and must furnish any necessary information to the State of Registry, which is the country where the aircraft is registered.
The obligations imposed by the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 on the parties and entities they govern include the requirement for the State of Design to provide necessary information to ensure the continuing airworthiness of aircraft types. The State of Registry must develop or adopt requirements to maintain the airworthiness of individual aircraft registered within its jurisdiction. CASA, acting on behalf of the Commonwealth, issues ADs as regulatory tools to address specific safety concerns or to mandate compliance with certain airworthiness standards. CASA must ensure that these directives are issued in accordance with the legislative framework provided by the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998, and they must review and potentially cancel ADs when the conditions that necessitated their issuance no longer exist.
In terms of potential breaches of the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998, the legislation does not explicitly detail specific offences or penalties related to the issuance or non-compliance with ADs. However, non-compliance with ADs can lead to significant safety risks, and CASA may take enforcement actions against operators or manufacturers who fail to comply with the directives. These actions could include administrative penalties, fines, or in severe cases, grounding of aircraft until compliance is achieved. The specific penalties and consequences for non-compliance are not explicitly stated in the provided text but are generally governed by the broader regulatory framework of aviation safety in Australia.
