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, the Civil Aviation Safety Authority (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.
CASA or its predecessors issued AD/R22/43 affecting Robinson R22 helicopters. CASA has reviewed this AD and as a result has cancelled it. The cancellation will become effective on 7 May 2009. No replacement AD is required.
As this AD has been cancelled because of Australia’s obligations under the Convention on International Civil Aviation, no consultation with the Australian public has taken place on this AD cancellation. 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 and Structures 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 Commonwealth Parliament, provides the legislative framework for ensuring the safety and efficiency of civil aviation within Australia. One of the Act's key functions is to enable the Governor-General to make regulations that promote the safety of air navigation, including the issuance of airworthiness directives. The Civil Aviation Safety Regulations 1998, made under the authority of this Act, further detail the procedures and responsibilities of the Civil Aviation Safety Authority (CASA) in managing airworthiness directives. These directives are legislative instruments designed to maintain the airworthiness of aircraft and aeronautical products, ensuring they meet safety standards as per international obligations, particularly those outlined in Annex 8 of the Convention on International Civil Aviation. CASA has the authority to issue, modify, or cancel such directives to comply with Australia's international commitments and to safeguard the safety of air navigation.
Scope and Application
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 establish the framework for the issuance of airworthiness directives (ADs) in Australia, specifically under section 98 and regulation 39.001 respectively. These regulations empower the Civil Aviation Safety Authority (CASA) to issue ADs for specific types of aircraft or aeronautical products to ensure the safety of air navigation. The ADs are considered legislative instruments, which are disallowable under section 46A of the Acts Interpretation Act 1901 and regulated under the Legislative Instruments Act 2003. The geographic scope of these regulations applies nationally within Australia, aligning with Australia's international obligations under Annex 8 to the Convention on International Civil Aviation. The State of Registry of an aircraft is primarily responsible for the continuing airworthiness of individual aircraft, while the State of Design must provide necessary information to ensure the airworthiness of aircraft types. The ADs serve as a primary means for disseminating continuing airworthiness information, and their issuance is a common practice among ICAO Contracting States, including Australia. Notably, the cancellation of specific ADs, such as AD/R22/43 for Robinson R22 helicopters, is subject to Australia's international obligations and does not require public consultation or a Regulatory Impact Statement.
Key Provisions
The Civil Aviation Safety Regulations 1998, under section 39.001, empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. These ADs are instrumental in maintaining the safety of air navigation, as they outline necessary maintenance, inspection, and operational requirements to ensure that aircraft remain airworthy. Section 98 of the Civil Aviation Act 1988 facilitates the creation of these regulations by the Governor-General, aiming to uphold safety standards in air navigation. Subregulation 39.001(5) further clarifies that ADs are legislative instruments, subject to disallowance provisions under the Acts Interpretation Act 1901 and oversight by the Legislative Instruments Act 2003.
The obligations imposed by these regulations are significant. CASA, as the issuing authority, must ensure that ADs are issued in line with international standards, particularly those set out in Annex 8 to the Convention on International Civil Aviation. The State of Design is responsible for the overall airworthiness of an aircraft type, and must provide necessary information to ensure its continued airworthiness. Meanwhile, the State of Registry, which in the context of Australia is CASA, must adopt or develop requirements to ensure that individual aircraft remain airworthy. This includes complying with ADs issued by CASA and ensuring that the aircraft meet all specified safety standards.
Failure to comply with ADs can result in serious consequences. Non-compliance can lead to significant safety risks, potentially resulting in civil or criminal penalties. While the specific penalties for breaching ADs are not detailed in the text, the issuance of ADs under the authority of the Civil Aviation Act 1988 implies that non-compliance can lead to enforcement actions by CASA. These actions may include fines, suspension or revocation of airworthiness certificates, and in severe cases, criminal charges against the operators or owners of non-compliant aircraft. The precise penalties would depend on the nature and severity of the breach, as well as the specific provisions of the Civil Aviation Act 1988 and related regulations.
