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 2005-17-16 affecting Pratt and Whitney JT8D series engines. The United States is the State of Design for these engine models. CASA has assessed this AD and has issued Australian AD/JT8D/41, which will become effective on 24 November 2005.
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 was enacted to ensure the safety and efficiency of civil aviation in Australia. This legislation provides the framework for regulating civil aviation activities, including the issuance of airworthiness directives to maintain the safety of aircraft. Under section 98 of the Act, the Governor-General has the authority to make regulations that contribute to the safety of air navigation. The Civil Aviation Safety Regulations 1998 further detail these regulations, with regulation 39.001 empowering the Civil Aviation Safety Authority (CASA) to issue airworthiness directives for specific kinds of aircraft or aeronautical products. These directives are legislative instruments subject to disallowance under the Acts Interpretation Act 1901 and the Legislative Instruments Act 2003. In line with international standards set by Annex 8 to the Convention on International Civil Aviation, the State of Design is responsible for the continuing airworthiness of an aircraft type, while the State of Registry must ensure the individual aircraft's airworthiness. CASA, as Australia’s national airworthiness authority, issues Australian airworthiness directives in response to directives from the State of Design, ensuring compliance with international obligations without the need for public consultation.
Scope and Application
The Civil Aviation Act 1988, as amended and enforced by the Civil Aviation Safety Regulations 1998, applies to all entities involved in civil aviation within Australia, including aircraft manufacturers, operators, and maintenance providers. Specifically, regulation 39.001 empowers the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for certain kinds of aircraft or aeronautical products. These directives are intended to ensure the safety of air navigation and are considered legislative instruments under the Acts Interpretation Act 1901. The ADs mandate compliance by the State of Registry, which, for Australian-registered aircraft, is CASA. The legislation extends its jurisdiction in accordance with international obligations under the Convention on International Civil Aviation, particularly Annex 8, which stipulates the responsibility of the State of Design in ensuring the continuing airworthiness of aircraft types. In this context, the application of ADs does not require public consultation or a Regulatory Impact Statement, as determined by the Office of Regulatory Review.
Key Provisions
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 (CASR) outline the regulatory framework for airworthiness directives (ADs). Section 98 of the Civil Aviation Act 1988 allows the Governor-General to make regulations for the safety of air navigation, while regulation 39.001 of the CASR empowers CASA to issue ADs for specific kinds of aircraft or aeronautical products. An AD is defined as a disallowable instrument under section 46A of the Acts Interpretation Act 1901 and is a legislative instrument under the Legislative Instruments Act 2003.
The Act and regulations impose several obligations on the parties involved. The State of Design, such as the United States for Pratt and Whitney JT8D series engines, has the responsibility to ensure the continuing airworthiness of an aircraft type and provide necessary information to the State of Registry, which is the country where the aircraft is registered. In this case, the State of Registry for an aircraft in Australia is CASA. CASA must assess the ADs issued by the State of Design and, if appropriate, issue Australian ADs to mandate the requirements for the Australian-registered aircraft.
Failure to comply with ADs can result in serious consequences. The Civil Aviation Act 1988 and CASR do not specify particular offences or penalties for non-compliance with ADs, but non-compliance can lead to severe civil or criminal consequences. The act of operating an aircraft that does not comply with an AD can be considered an offence under the Civil Aviation Act 1988, potentially resulting in fines or imprisonment. Additionally, CASA has the authority to take enforcement actions, including grounding non-compliant aircraft, which can have significant financial and operational impacts on the operator.
CASA, as the national airworthiness authority, is responsible for ensuring that ADs are issued and enforced in accordance with the regulatory framework. The AD process is designed to maintain safety standards by ensuring that aircraft meet the necessary airworthiness criteria. The ADs are issued in response to safety concerns identified by the State of Design and are intended to address any safety issues that could potentially compromise the aircraft's airworthiness. The absence of a public consultation process for ADs is justified by the need to promptly address safety issues as mandated by international agreements such as the Convention on International Civil Aviation.
