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/33 affecting Eurocopter SA365 Dauphin helicopters in 1992. 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 was enacted to provide a comprehensive legal framework for civil aviation in Australia, aiming to ensure the safety and efficiency of air navigation. One of the key mechanisms established under this Act is the ability for the Governor-General to make regulations, such as those concerning airworthiness directives, for the safety of air navigation. The Civil Aviation Safety Regulations 1998 further detail the processes and responsibilities for issuing these directives. In accordance with these regulations, the Civil Aviation Safety Authority (CASA) has the authority to issue airworthiness directives for specific types of aircraft or aeronautical products, ensuring that they meet continuing airworthiness standards. The Civil Aviation Safety Regulations also classify airworthiness directives as disallowable instruments, subject to the requirements of the Legislative Instruments Act 2003. This legislative framework is designed to maintain high safety standards in line with international conventions, such as Annex 8 to the Convention on International Civil Aviation, which assigns responsibilities to the States of Design and Registry for ensuring the continuing airworthiness of aircraft.
Scope and Application
The Civil Aviation Safety Regulations 1998, under section 39.001, empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives for specific types of aircraft or aeronautical products. These directives are legislative instruments, as confirmed by subregulation 39.001(5) and section 46A of the Acts Interpretation Act 1901. The Civil Aviation Act 1988 authorises the Governor-General to make such regulations to ensure the safety of air navigation. The issuing of airworthiness directives is further supported by Annex 8 to the Convention on International Civil Aviation, which mandates the State of Design to provide necessary information for continuing airworthiness and assigns the responsibility for the ongoing airworthiness of individual aircraft to the State of Registry. The AD/DAUPHIN/33, originally issued by CASA in 1992 for Eurocopter SA365 Dauphin helicopters, has been cancelled effective 27 August 2009, following a review by CASA which determined that the original unsafe condition no longer exists, thereby reducing the regulatory burden. No public consultation or Regulatory Impact Statement was required for this cancellation, as per the Office of Best Practice Regulation's determination.
Key Provisions
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 provide the framework within which airworthiness directives (ADs) are issued and managed in Australia. Under section 98 of the Civil Aviation Act 1988, the Governor-General has the authority to make regulations that promote the safety of air navigation, and regulation 39.001 of the Civil Aviation Safety Regulations 1998 specifically empowers the Civil Aviation Safety Authority (CASA) to issue ADs for certain kinds of aircraft or aeronautical products. These ADs are legislative instruments, as they are disallowable under section 46A of the Acts Interpretation Act 1901 and regulated by the Legislative Instruments Act 2003.
The obligations imposed by these provisions are significant for both CASA and the entities they regulate. CASA must ensure the continuing airworthiness of aircraft through the issuance of ADs, which are intended to address unsafe conditions that may arise with specific aircraft types or aeronautical products. The State of Design and the State of Registry each have specific responsibilities under Annex 8 to the Convention on International Civil Aviation. The State of Design must provide necessary information to ensure the airworthiness of aircraft types, while the State of Registry must develop or adopt requirements to ensure the continuing airworthiness of individual aircraft within its jurisdiction.
In terms of consequences for non-compliance, CASA's ADs carry specific legal weight. Failure to comply with an AD can result in serious safety risks and may lead to enforcement actions against the operators of non-compliant aircraft. While the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 do not explicitly detail the penalties for non-compliance with ADs, general aviation regulations and related acts may impose fines and other sanctions. For example, the Civil Aviation Act 1988 includes provisions for imposing fines and other penalties for violations that could potentially lead to imprisonment, depending on the severity of the breach and the specific circumstances.
In the case of the AD/DAUPHIN/33, which affected Eurocopter SA365 Dauphin helicopters, CASA has decided to cancel the directive. The cancellation reflects that the unsafe condition originally identified no longer exists, and thus, no further regulatory action is required. The decision to cancel the AD was made without public consultation, as the Office of Best Practice Regulation determined that ADs do not require a Regulatory Impact Statement. This reflects a reduction in regulatory burden and ensures that resources are focused on areas where they are most needed for aviation safety.
