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/BO 105/4 affecting Eurocopter BO 105 series helicopters. CASA has assessed this AD and as a result has cancelled Australian AD/BO 105/4. The cancellation will become effective on
30 July 2009. 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 a legislative framework for the regulation of civil aviation in Australia, ensuring the safety and efficiency of air navigation. This Act empowers the Governor-General to make regulations for the safety of air navigation, with the Civil Aviation Safety Regulations 1998 detailing specific regulatory provisions, including the issuance of airworthiness directives (ADs) under regulation 39.001. These ADs, as legislative instruments, are essential for maintaining the continuing airworthiness of aircraft and aeronautical products in accordance with international standards set by the Convention on International Civil Aviation. The Civil Aviation Safety Authority (CASA) is responsible for issuing ADs when necessary, ensuring that Australian-registered aircraft meet safety standards. In the case of Eurocopter BO 105 series helicopters, CASA assessed and subsequently cancelled the Australian AD/BO 105/4 as the unsafe condition no longer exists, reflecting Australia's commitment to international obligations and safety protocols.
Scope and Application
The Civil Aviation Act 1988, supported by the Civil Aviation Safety Regulations 1998, establishes the framework within which the Civil Aviation Safety Authority (CASA) can issue airworthiness directives (ADs) to ensure the safety of air navigation. These regulations empower CASA to issue ADs for specific kinds of aircraft or aeronautical products as stipulated under regulation 39.001, and such directives are considered legislative instruments under the Acts Interpretation Act 1901 and the Legislative Instruments Act 2003. ADs are critical for maintaining the continuing airworthiness of aircraft, a responsibility that falls upon the State of Registry, which in Australia is CASA. The State of Design must also provide necessary information to ensure the airworthiness of aircraft types, aligning with Annex 8 of the Convention on International Civil Aviation. CASA's role includes assessing information from the State of Design and issuing Australian ADs when necessary to address unsafe conditions identified by the State of Design. The AD/BO 105/4 concerning Eurocopter BO 105 series helicopters, issued by CASA, has been cancelled due to the resolution of the unsafe condition, effective from 30 July 2009, without necessitating a replacement AD. The process of issuing and cancelling ADs is conducted under Australia’s obligations under the Convention on International Civil Aviation, and it does not require public consultation or a Regulatory Impact Statement.
Key Provisions
The Civil Aviation Act 1988, through section 98, empowers the Governor-General to create regulations that ensure the safety of air navigation. This legislative framework is further elaborated in regulation 39.001 of the Civil Aviation Safety Regulations 1998, which grants the Civil Aviation Safety Authority (CASA) the authority to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. These ADs, as outlined in subregulation 39.001(5), are classified as disallowable instruments under section 46A of the Acts Interpretation Act 1901, and thus fall under the category of legislative instruments as defined in section 6 of the Legislative Instruments Act 2003.
The obligations imposed by the Act and the associated regulations are significant for both the State of Design and the State of Registry. The State of Design has the overarching responsibility for ensuring the continuing airworthiness of an aircraft type, as stipulated in Annex 8 to the Convention on International Civil Aviation. This entails providing necessary information to the States of Registry to maintain airworthiness. Conversely, the State of Registry is tasked with developing or adopting requirements to ensure the ongoing airworthiness of aircraft within its jurisdiction. When a State of Design issues an AD, CASA, as Australia's national airworthiness authority, must evaluate this information and, if deemed necessary, issue an Australian AD to enforce the requirements of the State of Design.
In a specific instance, CASA issued AD/BO 105/4 concerning Eurocopter BO 105 series helicopters, which has now been cancelled as of 30 July 2009. This cancellation was a result of Australia's obligations under the Convention on International Civil Aviation and the resolution of the unsafe condition that prompted the directive. Given the nature of this cancellation, no public consultation or Regulatory Impact Statement was required. The decision to cancel the AD was 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.
In terms of penalties and consequences, any breach of the ADs or the associated regulations can lead to civil or criminal liabilities. Although the specific penalties are not detailed in the provided text, it is understood that violations of airworthiness directives can result in significant repercussions, including fines and potential imprisonment, as per the general framework of the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998. These measures are in place to ensure compliance and uphold the highest standards of aviation safety.
