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 has issued AD 2008-0206 affecting Eurocopter Deutschland BK 117 series helicopters. Germany is the State of Design for this helicopter series. CASA has assessed this AD and has issued Australian AD/GBK 117/22, which will become effective on 12 February 2009.
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 Regulatory Review has determined that ADs do not require a Regulatory Impact Statement.
The AD has been made by the Manager, Systems and New Technologies, in the Airworthiness Engineering Group, on behalf of CASA, in accordance with subsection 84A (2) of the Act.
Overview
The Civil Aviation Act 1988, enacted by the Australian Parliament, aims to ensure the safety and efficiency of civil aviation within Australia. This legislation empowers the Governor-General to create regulations that promote the safety of air navigation. The Civil Aviation Safety Regulations 1998, which are made under the authority of this Act, further specify the regulatory framework for airworthiness and safety standards, including the issuance of airworthiness directives (ADs) by the Civil Aviation Safety Authority (CASA). These ADs serve as legislative instruments designed to mandate safety requirements for specific types of aircraft or aeronautical products, aligning with international standards set by the International Civil Aviation Organization (ICAO).
The Civil Aviation Safety Regulations 1998 provide CASA with the authority to issue ADs that respond to directives from the State of Design, ensuring the continuing airworthiness of aircraft registered in Australia. This approach upholds Australia’s commitment to international civil aviation agreements, such as the Convention on International Civil Aviation, and facilitates the consistent application of safety standards across jurisdictions. The issuing of ADs, such as the Australian AD/GBK 117/22 in response to the European Aviation Safety Agency’s AD 2008-0206 for the Eurocopter Deutschland BK 117 series helicopters, underscores the importance of harmonising safety regulations globally while maintaining local oversight responsibilities.
Scope and Application
The Civil Aviation Act 1988, supplemented by the Civil Aviation Safety Regulations 1998, applies to all individuals, entities, and industries involved in civil aviation within Australia, including aircraft operators, manufacturers, and maintenance providers. These regulations govern the issuance of airworthiness directives (ADs), which are legislative instruments used to mandate safety standards and requirements for aircraft to ensure continuing airworthiness. ADs are issued by the Civil Aviation Safety Authority (CASA), which acts as Australia's national airworthiness authority, in response to safety concerns identified by the State of Design or other international civil aviation authorities. The scope of these regulations extends to all aircraft registered in Australia, regardless of where they are manufactured or operated, and aligns with the requirements set forth in Annex 8 to the Convention on International Civil Aviation. This legislative framework is designed to maintain the highest safety standards in civil aviation, ensuring that all aircraft meet specific safety criteria and operational requirements.
Key Provisions
The Civil Aviation Act 1988, particularly section 98, empowers the Governor-General to enact regulations for the Act, focusing on air navigation safety. Under this provision, regulation 39.001 of the Civil Aviation Safety Regulations 1998 allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific aircraft types or aeronautical products. These ADs are considered disallowable instruments under section 46A of the Acts Interpretation Act 1901, and are formally recognised as legislative instruments as per section 6 of the Legislative Instruments Act 2003.
The obligations of the Act and the Regulations include the responsibility of the State of Design to ensure the continuing airworthiness of an aircraft type, as outlined in Annex 8 to the Convention on International Civil Aviation. The State of Design must provide necessary information to the States of Registry to maintain airworthiness. The State of Registry, in turn, must establish or adopt requirements to ensure the continuing airworthiness of registered aircraft. For example, when the European Aviation Safety Agency (EASA) issues an AD for a helicopter series, CASA must evaluate the AD and, if deemed necessary, issue a corresponding Australian AD to enforce the State of Design’s requirements.
The consequences for non-compliance with ADs are significant. Failure to comply with an AD can result in severe penalties. Under the Civil Aviation Act 1988, non-compliance may lead to enforcement actions, fines, and even imprisonment, depending on the severity of the breach. The specific maximum penalties are outlined in the regulations and may include substantial fines and imprisonment terms for serious violations, ensuring strict adherence to airworthiness directives.
Civil and criminal liabilities may also arise for operators who fail to comply with the ADs. These can include grounding of the affected aircraft, revocation of airworthiness certificates, and potential criminal charges against individuals responsible for non-compliance. Such legal repercussions underscore the importance of adhering to the ADs in maintaining aviation safety standards.
