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.
CASA issued AD/PA-20/10, affecting Piper PA-20 model aircraft in 1971. CASA has reviewed this AD and as a result has decided to cancel it. The cancellation will become effective on 17 January 2008. No replacement AD is required, as the original unsafe condition is now addressed by AD/GENERAL/74 Amendment 1.
No consultation with the Australian public has taken place on this AD cancellation, because the cancellation results in a reduction of the regulatory burden. 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 in the Airworthiness Engineering Branch, on behalf of CASA, in accordance with subsection 84A (2) of the Act.
Overview
The Civil Aviation Act 1988, enacted by the Australian Parliament, is designed to ensure the safety and efficiency of civil aviation in Australia. This Act empowers the Governor-General to create regulations that enhance air navigation safety, as exemplified by the Civil Aviation Safety Regulations 1998. These regulations allow the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. The ADs are considered legislative instruments under the Legislative Instruments Act 2003 and are intended to address safety issues that arise after an aircraft type has been certified as airworthy. CASA's role includes ensuring that the continuing airworthiness of aircraft on the Australian Register is maintained, often by issuing Australian ADs in response to directives from the State of Design. This legislative framework aims to uphold the highest safety standards in Australia's civil aviation sector, aligning with international standards set by the International Civil Aviation Organization (ICAO).
Scope and Application
The Civil Aviation Act 1988 provides the legislative framework for the regulation of civil aviation safety in Australia, and the Civil Aviation Safety Regulations 1998 further detail the specific requirements and procedures under this Act. The Act and its regulations apply to all persons and entities involved in civil aviation activities within Australia, including aircraft manufacturers, operators, maintenance providers, and aviation personnel. The Act extends to all aircraft registered in Australia, whether they are operating domestically or internationally, and applies to all aeronautical products used in these aircraft. 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 to ensure their continuing airworthiness, thereby fulfilling Australia’s obligations under international aviation safety conventions. Airworthiness directives, as legislative instruments, are subject to disallowance under section 46A of the Acts Interpretation Act 1901 and are not required to undergo a formal regulatory impact assessment or public consultation unless otherwise specified by the Office of Best Practice Regulation. The scope of these regulations can be extended or specified through subordinate instruments, ensuring that CASA can respond to emerging safety issues in a timely and effective manner.
Key Provisions
Under the Civil Aviation Act 1988, specifically section 98, the Governor-General is empowered to create regulations that are intended to ensure the safety of air navigation. These regulations are implemented with the overarching goal of enhancing the safety standards in the aviation sector. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 further elaborates on this by granting the Civil Aviation Safety Authority (CASA) the authority to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. This regulatory framework ensures that aircraft remain in a condition that is safe for operation throughout their service life.
The obligations imposed by these provisions are significant for both CASA and the aviation industry. CASA, as the national airworthiness authority, must review and assess any ADs issued by the State of Design concerning aircraft types registered in Australia. If an AD is deemed necessary, CASA must issue a corresponding Australian AD to enforce the requirements specified by the State of Design. This ensures that all aircraft operating in Australia meet the necessary safety standards. The State of Registry, which is responsible for the continuing airworthiness of individual aircraft, must also develop or adopt appropriate requirements to ensure compliance with these regulations. These obligations collectively ensure that the safety and airworthiness of aircraft are maintained at a high standard.
Failure to comply with the airworthiness directives or the regulations set forth by CASA can result in severe consequences. If an entity, such as an aircraft operator or manufacturer, does not adhere to the requirements specified in an AD, they may be subject to civil or criminal penalties. The severity of these penalties can vary, but they are intended to enforce compliance and ensure that safety standards are upheld. The maximum penalties for non-compliance can include substantial fines and, in some cases, criminal charges that could lead to imprisonment. These consequences are designed to act as a deterrent against any actions that could compromise the safety of air navigation.
