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 Civil Aviation Safety Authority or its predecessors issued AD/AC/11 affecting all Twin Aero Commander aircraft models. CASA has assessed this AD and as a result has cancelled Australian AD/AC/11. The cancellation will become effective on 31 July 2008. No replacement AD is required, as the unsafe condition no longer exists.
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, Systems and New Technologies, in the Airworthiness Engineering Branch, on behalf of CASA, in accordance with subsection 84A (2) of the Act.
Overview
The Civil Aviation Act 1988 is a foundational piece of Australian legislation that governs civil aviation within the country. Enacted in 1988, it provides the legal framework for the regulation of aviation safety, including the establishment of the Civil Aviation Safety Authority (CASA), which is responsible for ensuring the safety and efficiency of civil aviation in Australia. The Act was introduced to address the need for a comprehensive regulatory system that could maintain high safety standards in a rapidly evolving industry. This includes the authority to issue airworthiness directives, as outlined in the Civil Aviation Safety Regulations 1998, which allow CASA to mandate safety measures and ensure the continuing airworthiness of aircraft. The objective of the Act is to protect the public by maintaining the highest possible standards of safety in civil aviation, thereby fulfilling Australia's obligations under the Convention on International Civil Aviation.
Scope and Application
The Civil Aviation Act 1988 applies to the regulation of civil aviation within Australia, and encompasses a broad range of entities, including individuals, corporations, and aviation service providers. The Act authorises the Governor-General to make regulations for the safety of air navigation, with the Civil Aviation Safety Regulations 1998 being a primary instrument in this regard. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 empowers the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. These ADs, which are legislative instruments under the Acts Interpretation Act 1901, ensure compliance with international standards set forth by the Convention on International Civil Aviation. The geographic reach of these regulations is nationwide, impacting all aircraft registered in Australia and their operators. Notably, the Act does not provide specific exclusions or thresholds, but rather focuses on maintaining the highest safety standards through the issuance and enforcement of ADs. The application of these regulations can be further extended or refined through subordinate instruments, ensuring that CASA can respond effectively to emerging safety concerns.
Key Provisions
The Civil Aviation Act 1988, particularly in conjunction with the Civil Aviation Safety Regulations 1998, provides a framework for the issuance of airworthiness directives (ADs). Under section 98 of the Civil Aviation Act 1988, the Governor-General has the authority to create regulations that ensure the safety of air navigation. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 empowers the Civil Aviation Safety Authority (CASA) to issue ADs for specific types of aircraft or aeronautical products. This regulation is integral to maintaining safety standards within the aviation industry. These ADs serve as legal instruments that dictate necessary actions to maintain airworthiness, and as per subregulation 39.001(5), they are considered disallowable instruments under the Acts Interpretation Act 1901.
The obligations imposed by the Civil Aviation Safety Regulations 1998 on parties governed by these provisions are significant. The State of Design, which is the country where the aircraft was designed, holds the primary responsibility for ensuring the continuing airworthiness of the aircraft type. This responsibility includes providing necessary information to the States of Registry to ensure ongoing compliance with airworthiness standards. The State of Registry, on the other hand, is tasked with developing or adopting the requirements that ensure the continuing airworthiness of individual aircraft within its jurisdiction. CASA, acting as Australia's national airworthiness authority, must review any ADs issued by the State of Design and, if necessary, issue corresponding Australian ADs to enforce these requirements. This collaborative approach ensures that safety standards are consistently upheld across all jurisdictions.
Failure to comply with airworthiness directives can result in serious legal consequences. The Civil Aviation Act 1988, alongside the Civil Aviation Safety Regulations 1998, outlines the potential penalties for non-compliance with ADs. Civil penalties may include fines and other civil remedies, while criminal penalties can include imprisonment, depending on the severity and impact of the non-compliance. For instance, if an aircraft operator fails to adhere to an AD, they could face substantial fines and potential imprisonment, underscoring the importance of strict compliance with these regulations. The exact penalties can vary based on the specific circumstances of the breach and the regulatory framework governing such infractions.
