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 EASA issued AD 2007-0211 affecting Eurocopter EC 120 helicopters. The EASA is the State of Design for these helicopters. CASA has amended the equivalent Australian AD to AD/EC 120/14 Amendment 1 which will become effective on 25 October 2007. 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, 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 comprehensive framework for the regulation of civil aviation in Australia, ensuring safety and efficiency in the aviation industry. Under section 98 of this Act, the Governor-General is empowered to make regulations, including issuing airworthiness directives, to maintain the safety of air navigation. The Civil Aviation Safety Regulations 1998, made pursuant to the Act, further elaborate on the regulatory framework by enabling the Civil Aviation Safety Authority (CASA) to issue airworthiness directives for specific kinds of aircraft or aeronautical products. These directives are crucial for maintaining the continuing airworthiness of aircraft and are aligned with international standards as set out in Annex 8 to the Convention on International Civil Aviation. The issuing of airworthiness directives, such as the AD/EC 120/14 Amendment 1 for Eurocopter EC 120 helicopters, is a direct response to obligations under international conventions and is managed by CASA to ensure compliance with both domestic and international safety standards.
Scope and Application
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 establish the framework for issuing airworthiness directives (ADs) in Australia, which are legislative instruments aimed at ensuring the continuing airworthiness of aircraft. Under the authority granted by section 98 of the Civil Aviation Act 1988, the Governor-General can make regulations, including ADs, for the safety of air navigation. The Civil Aviation Safety Regulations 1998, specifically regulation 39.001, empower the Civil Aviation Safety Authority (CASA) to issue these directives for particular types of aircraft or aeronautical products. The State of Design, responsible for the continuing airworthiness of an aircraft type, must provide necessary information to States of Registry, which include Australia. CASA, as Australia's national airworthiness authority, evaluates this information and issues corresponding Australian ADs. These ADs are mandated by the State of Registry to ensure aircraft meet required safety standards, aligning with Australia’s obligations under the Convention on International Civil Aviation. The process of issuing ADs does not involve public consultation or require a Regulatory Impact Statement, as determined by the Office of Best Practice Regulation.
Key Provisions
The Civil Aviation Act 1988, particularly section 98, empowers the Governor-General to create regulations for the safety of air navigation. In line with this, regulation 39.001 of the Civil Aviation Safety Regulations 1998 allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific kinds of aircraft or aeronautical products. These directives are intended to ensure the continuing airworthiness of aircraft, which is a crucial aspect of aviation safety. According to subregulation 39.001(5), ADs are considered disallowable instruments under section 46A of the Acts Interpretation Act 1901 and, consequently, legislative instruments under section 6 of the Legislative Instruments Act 2003.
Under the Civil Aviation Safety Regulations 1998, the State of Design for an aircraft type has the responsibility to ensure its continuing airworthiness and must provide necessary information to the States of Registry. This information is typically disseminated in the form of ADs, which are used by most ICAO Contracting States. The State of Registry, in this case, CASA, must evaluate this information and, if deemed appropriate, issue an Australian AD to enforce the State of Design’s requirements. This ensures that the safety standards set by the State of Design are adhered to within Australia.
The obligations imposed by this Act and the associated regulations require CASA to meticulously assess any ADs issued by the State of Design, such as the European Aviation Safety Agency (EASA), and to adapt these into Australian ADs if necessary. This was exemplified when EASA issued AD 2007-0211 affecting Eurocopter EC 120 helicopters. CASA then amended the equivalent Australian AD to AD/EC 120/14 Amendment 1, which became effective on 25 October 2007. This amendment replaced the previous AD, ensuring the Australian regulatory framework remained aligned with international safety standards.
Failure to comply with an AD can result in significant consequences. Under section 84A(2) of the Civil Aviation Act 1988, CASA has the authority to take action against any aircraft that does not comply with an AD. The consequences of non-compliance can include civil penalties, such as fines, and criminal charges, which may lead to imprisonment. The severity of the penalties can vary depending on the nature and extent of the non-compliance, but the overarching goal is to ensure that all aircraft operating within Australia meet the necessary safety standards. The regulatory framework thus aims to protect public safety and maintain high standards in aviation.
