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 80-17-05 affecting OH-58A (BELL 206A-1) model helicopters. The USA is the State of Design for this type. CASA has assessed this AD and has issued Australian AD/OH-58/4, which will become effective on
28 August 2008.
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 in the Airworthiness Engineering Branch, on behalf of CASA, in accordance with subsection 84A (2) of the Act.
Overview
The Civil Aviation Act 1988 was enacted to provide a framework for the regulation of civil aviation in Australia, with a strong emphasis on ensuring the safety of air navigation. This Act empowers the Governor-General to make regulations, which include the Civil Aviation Safety Regulations 1998, that serve the interests of aviation safety. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 enables the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products, making ADs legislative instruments under the Acts Interpretation Act 1901. This legislative framework is designed to ensure that Australia meets its international obligations under the Convention on International Civil Aviation, particularly concerning the continuing airworthiness of aircraft types.
The issuance of ADs, such as the Australian AD/OH-58/4 in response to the US Federal Aviation Administration's AD 80-17-05 for OH-58A (BELL 206A-1) model helicopters, reflects Australia's commitment to maintaining high safety standards in line with international practices. The ADs are issued by CASA, acting as Australia's national airworthiness authority, following the assessment of information provided by the State of Design. Given the nature of these directives and their basis in international obligations, no public consultation is required, and the Office of Best Practice Regulation has determined that such ADs do not necessitate a Regulatory Impact Statement. This streamlined process ensures timely responses to safety concerns while adhering to international standards and obligations.
Scope and Application
The Civil Aviation Safety Regulations 1998 empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) concerning specific types of aircraft or aeronautical products, as stipulated in regulation 39.001. Such directives are legislative instruments subject to disallowance under section 46A of the Acts Interpretation Act 1901 and must comply with the Legislative Instruments Act 2003. These ADs play a crucial role in ensuring the continuing airworthiness of aircraft types and are typically issued by the State of Design, which holds overarching responsibility under Annex 8 of the Convention on International Civil Aviation. The State of Registry, including CASA in Australia, must ensure that these directives are appropriately assessed and implemented within their jurisdiction. In the case of the OH-58A (BELL 206A-1) model helicopters, CASA has issued AD/OH-58/4 following an assessment of a corresponding AD from the US Federal Aviation Administration, reflecting Australia's commitment to international civil aviation standards. Given the international context and the regulatory nature of ADs, there has been no requirement for public consultation or a Regulatory Impact Statement. The AD was issued by the Manager, Airframes in the Airworthiness Engineering Branch of CASA, in line with the Civil Aviation Act 1988.
Key Provisions
The Civil Aviation Act 1988, as amended, and the Civil Aviation Safety Regulations 1998 lay down the framework for the issuance of airworthiness directives (ADs) (sections 98 and 39.001). These ADs are regulatory instruments designed to ensure that aircraft and aeronautical products maintain their airworthiness. ADs are issued by the Civil Aviation Safety Authority (CASA) under regulation 39.001(5), and they function as legislative instruments under section 6 of the Legislative Instruments Act 2003. They are critical for ensuring compliance with safety standards established by the State of Design and must be adhered to by the State of Registry.
The obligations imposed on parties by the Act and the Regulations are stringent. The State of Design is responsible for the ongoing airworthiness of an aircraft type, and it must provide all necessary information to the States of Registry to ensure that the aircraft remain airworthy. The State of Registry, in this case CASA, must then assess the information provided by the State of Design and, if necessary, issue an AD to enforce the required safety measures. This ensures that any identified safety issues are addressed promptly and effectively across all registered aircraft of that type.
Failure to comply with the ADs can lead to serious consequences. While the specific offences and penalties are not detailed in the provided text, it is reasonable to infer that non-compliance with ADs could result in enforcement actions, penalties, or even criminal charges, depending on the severity and intent behind the breach. Such actions are typically aimed at ensuring that all parties adhere to the stringent safety standards established by the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998. The overarching goal is to maintain the highest possible level of safety in air navigation and to protect the public from potential hazards associated with non-compliant aircraft.
