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/HU 369/36 affecting McDonnell Douglas (Hughes) 369 series Helicopters. CASA has assessed this AD and as a result has cancelled Australian AD/HU 369/36. The cancellation will become effective on 4 June 2009. 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 Group, on behalf of CASA, in accordance with subsection 84A (2) of the Act.
Overview
The Civil Aviation Act 1988 was enacted to provide a legal framework for civil aviation safety and efficiency in Australia, addressing the need for comprehensive and integrated regulation to ensure safe and orderly air navigation. The Act empowers the Governor-General to make regulations that are essential for the safety of air navigation. Under the Act, the Civil Aviation Safety Regulations 1998 were introduced to further detail the implementation of safety standards, including the issuance of airworthiness directives (ADs). These directives serve as a means to ensure the continuing airworthiness of aircraft and aeronautical products, aligning with international standards set by the International Civil Aviation Organization (ICAO). The Civil Aviation Safety Authority (CASA) has the authority to issue ADs, which are considered legislative instruments, and these are subject to disallowance by Parliament. The policy objective of the Act and the associated regulations is to maintain the highest safety standards in civil aviation, thereby protecting the public and contributing to the efficient operation of the aviation industry.
Scope and Application
The Civil Aviation Act 1988, supported by the Civil Aviation Safety Regulations 1998, authorises the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) that apply to specific types of aircraft or aeronautical products. These regulations are intended to ensure the safety of air navigation in Australia, with CASA acting as the national airworthiness authority. ADs are legislative instruments under Australian law, and they align with the international standards set out in Annex 8 to the Convention on International Civil Aviation, which places responsibility for the continuing airworthiness of aircraft on both the State of Design and the State of Registry. CASA's issuance of ADs is integral to fulfilling Australia's obligations under the Convention, particularly when ADs are issued by the State of Design of an aircraft type registered in Australia. The scope of these ADs includes mandating compliance with the safety requirements specified by the State of Design. The authority to issue and cancel ADs, such as AD/HU 369/36 for McDonnell Douglas (Hughes) 369 series Helicopters, is exercised by CASA without the need for public consultation or a Regulatory Impact Statement, as determined by the Office of Best Practice Regulation. This legislative framework ensures that CASA can efficiently manage the airworthiness of aircraft registered in Australia, thereby maintaining high safety standards in line with international conventions.
Key Provisions
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. Section 98 of the Civil Aviation Act 1988 supports this authority, enabling the Governor-General to enact regulations that serve the safety of air navigation. Regulation 39.001(5) further classifies ADs as disallowable instruments under section 46A of the Acts Interpretation Act 1901, and as legislative instruments pursuant to section 6 of the Legislative Instruments Act 2003. These provisions underscore the regulatory framework that CASA operates within, ensuring that airworthiness directives are issued in a manner that aligns with overarching safety standards.
The obligations imposed by these regulations extend to both the State of Design and the State of Registry. Under Annex 8 to the Convention on International Civil Aviation, the State of Design is responsible for the continuing airworthiness of an aircraft type, requiring it to furnish necessary information to the appropriate States of Registry. Conversely, the State of Registry is tasked with developing or adopting requisite measures to ensure the continuing airworthiness of individual aircraft. In the case of Australia, CASA acts as the national airworthiness authority, obligated to assess information from the State of Design and, if necessary, issue corresponding Australian ADs that enforce the requirements of the originating State.
Breaching the obligations set forth by the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 can lead to significant consequences. While specific offences and penalties are not detailed in the provided text, it is reasonable to infer that non-compliance with ADs or failure to maintain airworthiness could result in both civil and criminal liabilities. Such breaches could potentially encompass fines, imprisonment, or other regulatory sanctions as stipulated by relevant laws. Given the critical nature of air safety, penalties for non-compliance are likely stringent, reflecting the high stakes involved in aviation safety regulations.
The cancellation of AD/HU 369/36 affecting McDonnell Douglas (Hughes) 369 series Helicopters, as detailed in the explanatory statement, serves as a specific example of the regulatory process in action. CASA, after assessing the information, determined that the unsafe condition identified by the AD no longer existed, leading to the cancellation of the directive. This decision, effective from 4 June 2009, was made in accordance with subsection 84A(2) of the Civil Aviation Act 1988. Notably, no public consultation or Regulatory Impact Statement was required due to the nature of the cancellation as dictated by Australia’s international obligations under the Convention on International Civil Aviation.
