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 United States FAA has issued AD 2005-26-10 affecting ECi cylinder assemblies fitted to various Lycoming engines. The United States is the State of Design for this engine type. CASA has assessed this AD and has issued Australian AD/LYC/113 which will become effective on 16 February 2006.
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, New Technologies and Systems, in the Manufacturing, Certification and New Technologies Office, on behalf of CASA, in accordance with subsection 84A (2) of the Act.
Overview
The Civil Aviation Act 1988, enacted by the Australian Parliament, was introduced to regulate civil aviation within Australia, ensuring the safety and efficiency of air navigation. One of the key mechanisms under this Act is the issuance of airworthiness directives (ADs), which are implemented to address safety concerns and ensure the continuing airworthiness of aircraft. The Civil Aviation Safety Regulations 1998 provide the regulatory framework for these directives, stipulating that they are legislative instruments subject to disallowance. The Civil Aviation Safety Authority (CASA) is responsible for issuing ADs based on assessments of international directives, ensuring compliance with international standards and obligations under the Convention on International Civil Aviation. This process is particularly evident in the issuance of Australian AD/LYC/113 in response to a United States Federal Aviation Administration directive concerning ECi cylinder assemblies in Lycoming engines, demonstrating Australia's commitment to international safety standards while maintaining domestic aviation safety.
Scope and Application
The Civil Aviation Act 1988 applies to aviation safety matters within Australia and extends to ensuring the safety of air navigation, including the issuance of airworthiness directives. The Act empowers the Governor-General to make regulations that align with the Act’s objectives, particularly concerning the safety of air navigation. The Civil Aviation Safety Regulations 1998 further specify that the Civil Aviation Safety Authority (CASA) can issue airworthiness directives for certain kinds of aircraft or aeronautical products. These directives are considered legislative instruments, as they are disallowable instruments under the Acts Interpretation Act 1901 and subject to the Legislative Instruments Act 2003. The geographic reach of these directives is national, as CASA acts on behalf of Australia to ensure compliance with international standards set by the International Civil Aviation Organization (ICAO). The ADs are issued in response to international obligations and directives from the State of Design, without the need for public consultation or a Regulatory Impact Statement. The issuance of these directives is a mandatory process that CASA undertakes to maintain the continuing airworthiness of aircraft registered in Australia.
Key Provisions
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 lay out the framework for issuing airworthiness directives (ADs) under section 98 of the Act (section 98) and regulation 39.001 of the Regulations (regulation 39.001). Section 98 allows the Governor-General to make regulations for air navigation safety, and regulation 39.001 empowers the Civil Aviation Safety Authority (CASA) to issue ADs for types of aircraft or aeronautical products. Subregulation 39.001(5) specifies that ADs are disallowable instruments under the Acts Interpretation Act 1901 and legislative instruments under the Legislative Instruments Act 2003. These ADs are pivotal in ensuring that aircraft maintain their airworthiness standards.
The obligations imposed by the Civil Aviation Safety Regulations 1998 are primarily centred around ensuring the continuing airworthiness of aircraft. The State of Design, which is the country where the aircraft type is designed, has the primary responsibility under Annex 8 to the Convention on International Civil Aviation to ensure that the type of aircraft continues to be airworthy. This includes providing necessary information to the State of Registry—the country where the aircraft is registered. The State of Registry, in turn, must develop or adopt requirements to ensure the continuing airworthiness of aircraft within its jurisdiction. When a State of Design issues an AD for a type of aircraft registered in Australia, CASA must assess the directive and, if necessary, issue a corresponding Australian AD to enforce the State of Design’s requirements.
In terms of civil or criminal consequences, the Civil Aviation Safety Regulations 1998 and the Civil Aviation Act 1988 do not explicitly outline specific offences or penalties for non-compliance with ADs. However, non-compliance with ADs could potentially lead to enforcement actions by CASA, which might include grounding the aircraft until the required actions are taken. While the specific penalties for non-compliance are not detailed in the regulations, failing to adhere to an AD could result in significant safety risks and potential legal ramifications. CASA has the authority to take necessary actions to ensure compliance with ADs to maintain the highest safety standards in civil aviation.
The process of issuing an AD in Australia, as illustrated by the case of AD 2005-26-10 from the United States Federal Aviation Administration (FAA) affecting ECi cylinder assemblies on various Lycoming engines, demonstrates the international coordination required to maintain airworthiness. CASA issued Australian AD/LYC/113 in response to the US AD, illustrating the procedural steps taken by CASA to ensure that Australian-registered aircraft meet international safety standards. Given that these ADs are issued under international obligations and in response to directives from the State of Design, they do not require public consultation or a Regulatory Impact Statement, as determined by the Office of Regulatory Review. This streamlined process ensures that safety directives are implemented without unnecessary delays.
