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 European Aviation Safety Authority (EASA) has issued AD 2007-0289 affecting Eurocopter AS350 series helicopters. EASA acts on behalf of France, the State of Design for this type. CASA has assessed this AD and has issued Australian AD/ECUREUIL/130, which will become effective on 13 March 2008.
As this AD is issued because of Australia’s obligations under Convention on International Civil Aviation, and because it is issued in response to an AD raised by the relevant State of Design, no consultation of the Australian public has taken place on this AD. 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, Systems in the Airworthiness 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 framework for the regulation of civil aviation in Australia, ensuring the safety and efficiency of air navigation. This legislation empowers the Governor-General to make regulations that are in the interests of the safety of air navigation. Complementing this, the Civil Aviation Safety Regulations 1998 further detail the requirements for maintaining the airworthiness of aircraft, including the issuance of airworthiness directives (ADs). ADs are legislative instruments that mandate specific safety measures for certain types of aircraft or aeronautical products, as per regulation 39.001 of the Civil Aviation Safety Regulations 1998. The issuance of these directives by the Civil Aviation Safety Authority (CASA) aligns with international standards, particularly under Annex 8 to the Convention on International Civil Aviation, which stipulates the responsibilities of the State of Design and the State of Registry in ensuring the continuing airworthiness of aircraft. As such, CASA issues Australian ADs in response to directives from the relevant State of Design, such as the recent AD/ECUREUIL/130 for Eurocopter AS350 series helicopters, reflecting Australia's commitment to international civil aviation safety standards.
Scope and Application
The Civil Aviation Act 1988 provides the legislative framework for civil aviation in Australia, including the regulation of airworthiness directives (ADs). Under this Act, the Governor-General has the authority to issue regulations in the interests of air navigation safety. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 specifically empowers the Civil Aviation Safety Authority (CASA) to issue ADs for certain types of aircraft or aeronautical products, making these ADs legislative instruments under the Legislative Instruments Act 2003. The ADs serve to ensure the continuing airworthiness of aircraft types, in line with the obligations under the Convention on International Civil Aviation, where the State of Design has the primary responsibility for airworthiness and the State of Registry must implement and enforce these requirements within its jurisdiction. In this context, CASA must assess and, if necessary, issue corresponding ADs when an AD is issued by the relevant State of Design. This process ensures compliance with international standards and Australia's obligations under the Convention, without the need for public consultation or a Regulatory Impact Statement, as the ADs are directly related to international obligations.
Key Provisions
The Civil Aviation Act 1988, particularly section 98, grants the Governor-General the authority to issue regulations aimed at enhancing the safety of air navigation. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 empowers the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. It is crucial to note that under subregulation 39.001(5), an AD is considered a disallowable instrument, as per section 46A of the Acts Interpretation Act 1901, and is classified as a legislative instrument according to section 6 of the Legislative Instruments Act 2003. These ADs are fundamental for maintaining the continuing airworthiness of aircraft types and ensuring compliance with international standards set forth in Annex 8 to the Convention on International Civil Aviation.
In accordance with the responsibilities outlined in Annex 8, the State of Design, which is the country where the aircraft type is designed, bears the overall responsibility for the continuing airworthiness of the aircraft. This includes providing any necessary information to ensure the aircraft's airworthiness to the States of Registry, which are the countries where the individual aircraft are registered. The State of Registry must develop or adopt specific requirements to ensure that the aircraft remain airworthy. When the State of Design issues an AD, CASA, as Australia's national airworthiness authority, must assess this information and, if deemed appropriate, issue an Australian AD to mandate the requirements of the State of Design. This ensures that Australian aircraft meet international safety standards.
The European Aviation Safety Authority (EASA) has recently issued AD 2007-0289 concerning Eurocopter AS350 series helicopters. As France is the State of Design for this helicopter type, EASA acts on its behalf. CASA has evaluated this AD and subsequently issued Australian AD/ECUREUIL/130, effective from 13 March 2008. Given that this AD is issued due to Australia's obligations under the Convention on International Civil Aviation and in response to an AD from the relevant State of Design, there has been no consultation with the Australian public regarding this directive. Additionally, the Office of Best Practice Regulation has determined that ADs do not require a Regulatory Impact Statement. This AD was issued by the Manager, Systems in the Airworthiness Engineering Branch on behalf of CASA, in accordance with subsection 84A(2) of the Act.
The obligations and requirements imposed by these ADs on the parties and entities governed by the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 are stringent. Aircraft operators and owners must comply with the ADs issued by CASA, ensuring that any specified actions or modifications are carried out within the stipulated timeframes. Failure to adhere to these directives can result in significant legal and safety consequences. CASA has the authority to enforce compliance and may take actions such as grounding non-compliant aircraft or imposing fines. The maximum penalties for non-compliance with ADs can include substantial fines and, in severe cases, imprisonment, depending on the severity of the breach and the potential risk to public safety. It is imperative for all stakeholders to understand and comply with these requirements to maintain the highest standards of aviation safety.
