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 US FAA has issued AD 2009-05-09 affecting Bell 412 model helicopters. The USA is the State of Design for this type. CASA has assessed this AD and has issued Australian AD/BELL 412/57, which will become effective on 31 March 2009.
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 Best Practice Regulation has determined that ADs do not require a Regulatory Impact Statement.
The AD has been made by the Manager, Airframes & 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 to ensure the safety and efficiency of civil aviation within Australia, provides the legislative framework within which the Civil Aviation Safety Regulations 1998 operate. This Act empowers the Governor-General to create regulations that support the Act's overarching goal of enhancing the safety of air navigation. A key component of this regulatory framework is the issuance of airworthiness directives (ADs) by the Civil Aviation Safety Authority (CASA) as stipulated in regulation 39.001 of the Civil Aviation Safety Regulations 1998. These directives, which are legislative instruments under the Legislative Instruments Act 2003, are crucial for maintaining the continuing airworthiness of aircraft, aligning with international standards set by the International Civil Aviation Organization (ICAO). In this context, CASA, acting on Australia’s obligations under the Convention on International Civil Aviation, issues ADs in response to directives from the aircraft's State of Design, ensuring compliance with both national and international safety standards.
Scope and Application
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 in accordance with section 98 of the Civil Aviation Act 1988. This legislative framework ensures the safety of air navigation and mandates CASA's role as Australia's national airworthiness authority. Each AD is a disallowable instrument and a legislative instrument under the Acts Interpretation Act 1901 and the Legislative Instruments Act 2003, respectively. ADs are a crucial mechanism under Annex 8 of the Convention on International Civil Aviation for maintaining the continuing airworthiness of aircraft, with the State of Design having primary responsibility for issuing such directives. The State of Registry, which is the country where the aircraft is registered, must then implement these directives to ensure compliance with airworthiness standards. For instance, following the issuance of an AD by the US Federal Aviation Administration (FAA) for Bell 412 model helicopters, CASA assessed the directive and issued its own corresponding AD for Australian-registered helicopters. This process reflects Australia's commitment to international aviation safety standards and its obligations under the Convention on International Civil Aviation.
Key Provisions
The Civil Aviation Act 1988 provides the framework for regulating air navigation in Australia, and under section 98, the Governor-General is empowered to make regulations to ensure the safety of air navigation. Specifically, regulation 39.001 of the Civil Aviation Safety Regulations 1998 allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. These directives, as noted in subregulation 39.001(5), are classified as disallowable instruments under section 46A of the Acts Interpretation Act 1901 and are thus legislative instruments as per section 6 of the Legislative Instruments Act 2003. This regulatory structure ensures that ADs can be issued swiftly and effectively to address safety concerns.
The obligations imposed by these provisions are significant. The State of Design, which in this case is the United States for the Bell 412 model helicopter, has a responsibility under Annex 8 to the Convention on International Civil Aviation to maintain the continuing airworthiness of the aircraft type and to provide necessary information to States of Registry. For Australia, CASA, as the national airworthiness authority, must assess any AD issued by the State of Design and, if appropriate, issue an Australian AD to enforce the required safety measures. This ensures that Australian-registered aircraft meet international safety standards.
Failure to comply with an AD can result in severe consequences. Under the Civil Aviation Act 1988, an operator who does not comply with an AD may face penalties. Civil penalties can include fines up to $12,600 for individuals and $63,000 for corporations, with additional penalties for continued non-compliance. Criminal penalties may also apply, where CASA can take legal action against the operator, potentially leading to imprisonment for up to two years. Furthermore, non-compliance can result in the grounding of the aircraft, which could disrupt operations and potentially endanger lives.
In summary, the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 establish a robust framework for issuing airworthiness directives to ensure the safety of air navigation. The obligations on the State of Design and the State of Registry are clearly defined, with CASA playing a pivotal role in assessing and enforcing these directives. The consequences for non-compliance are severe, involving both civil and criminal penalties, underscoring the critical importance of adhering to these regulations.
