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 2006-0248 affecting Eurocopter AS 350 model 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/100, Amendment 2, which will become effective on 5 June 2008. This AD cancels and replaces the previous issue.
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, Airframes 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 comprehensive legal framework for the regulation of civil aviation in Australia, with a primary focus on ensuring the safety of air navigation. Under this Act, the Governor-General has the authority to make regulations that support the Act's objectives, and these regulations include the Civil Aviation Safety Regulations 1998. The latter allow the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products, which are considered legislative instruments under the Legislative Instruments Act 2003. The ADs are essential for maintaining the continuing airworthiness of aircraft in accordance with international standards set by the Convention on International Civil Aviation. The issuing of these directives is part of Australia's commitment to ensuring that all aircraft registered in the country meet necessary safety standards, in alignment with the responsibilities of the State of Registry and the State of Design as outlined in Annex 8 of the Convention.
Scope and Application
The Civil Aviation Act 1988, along with the Civil Aviation Safety Regulations 1998, applies to various entities within the aviation sector, particularly those involved in air navigation and the maintenance of aircraft. 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, ensuring that these entities adhere to safety standards mandated by the Act. This legislation extends its application to any aircraft registered in Australia, thereby obligating these aircraft's operators to comply with ADs issued by CASA. The geographic scope of this Act and its regulations is national, covering all aircraft within Australia, and it is in alignment with international standards set by the International Civil Aviation Organization (ICAO). Importantly, ADs are legislative instruments that do not require public consultation or a Regulatory Impact Statement, as determined by the Office of Best Practice Regulation. This streamlined process allows CASA to swiftly address safety concerns by issuing directives in response to international safety mandates, such as the European Aviation Safety Authority's AD 2006-0248, which CASA has adapted as Australian AD/ECUREUIL/100, Amendment 2.
Key Provisions
The Civil Aviation Act 1988, as amended, and the Civil Aviation Safety Regulations 1998 provide the legislative framework under which airworthiness directives (ADs) are issued. Section 98 of the Act empowers the Governor-General to make regulations for the safety of air navigation, while regulation 39.001 of the Regulations allows the Civil Aviation Safety Authority (CASA) to issue ADs for types of aircraft or aeronautical products. An AD is considered a disallowable instrument under section 46A of the Acts Interpretation Act 1901 and is classified as a legislative instrument in accordance with section 6 of the Legislative Instruments Act 2003.
The obligations imposed by these provisions include the requirement for CASA to evaluate any ADs issued by the State of Design and, if deemed appropriate, issue corresponding Australian ADs to ensure compliance with international safety standards. Specifically, under Annex 8 to the Convention on International Civil Aviation, the State of Design is responsible for the continuing airworthiness of an aircraft type and must provide necessary information to States of Registry. The State of Registry, in turn, is mandated to implement measures that ensure the continuing airworthiness of individual aircraft. For example, when the European Aviation Safety Authority (EASA) issues an AD affecting a type of aircraft registered in Australia, CASA must assess this directive and issue an Australian AD if necessary.
Failure to comply with an AD can have serious consequences. Under section 84A(2) of the Act, CASA has the authority to issue ADs to ensure compliance with safety standards. Non-compliance with these directives can lead to safety risks, and in severe cases, can result in criminal or civil penalties. The Civil Aviation Safety Regulations 1998 and other related legislation outline the specific penalties for non-compliance, which may include fines and imprisonment. It is crucial for operators and manufacturers to adhere to these directives to maintain the safety and airworthiness of aircraft.
In summary, the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 establish a robust framework for the issuance and enforcement of ADs to ensure the safety and airworthiness of aircraft. CASA’s role in assessing and implementing these directives is critical in maintaining compliance with international standards and ensuring the safety of air navigation.
