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 2008-10-03 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 412/55, which will become effective on 21 May 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 establish a legal framework for the regulation of civil aviation in Australia, with a primary focus on ensuring the safety of air navigation. This Act empowers the Governor-General to make regulations, including the issuance of airworthiness directives, to safeguard the safety of air navigation. The Civil Aviation Safety Regulations 1998, under regulation 39.001, further allow the Civil Aviation Safety Authority (CASA) to issue airworthiness directives for specific types of aircraft or aeronautical products. This regulatory mechanism is crucial in maintaining the continuing airworthiness of aircraft as required under international conventions, such as Annex 8 to the Convention on International Civil Aviation. The policy objective behind these regulations is to ensure that all aircraft operating in Australia meet the necessary safety standards, thereby protecting the public and facilitating international air travel.
In accordance with the legislative framework established by the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998, CASA issued Australian AD/BELL 412/55 in response to an airworthiness directive issued by the US Federal Aviation Administration (FAA) for Bell 412 model helicopters. As the State of Design for this aircraft type, the USA is responsible for ensuring the continuing airworthiness of the Bell 412 model, and CASA has assessed and adopted this directive for application in Australia. This action is in line with Australia's obligations under international civil aviation agreements and has been executed without public consultation, as it pertains to international obligations and standards. The Manager, Airframes in the Airworthiness Engineering Branch, issued this airworthiness directive on behalf of CASA, in compliance with the legislative requirements set out in the Civil Aviation Act 1988.
Scope and Application
The Civil Aviation Act 1988 and Civil Aviation Safety Regulations 1998 provide the legal framework for the issuance of airworthiness directives (ADs) in Australia. Under these regulations, the Civil Aviation Safety Authority (CASA) can issue ADs for specific types of aircraft or aeronautical products to ensure the safety of air navigation, as mandated by section 98 of the Act and regulation 39.001 of the Regulations. These ADs, which are legislative instruments, are designed to maintain the continuing airworthiness of aircraft in line with international standards, particularly those set out in Annex 8 to the Convention on International Civil Aviation. The State of Design, such as the United States for certain aircraft types, is responsible for issuing ADs, and CASA, as Australia's national airworthiness authority, must assess and, if necessary, issue corresponding Australian ADs to enforce the requirements. This process is typically driven by international obligations and the need to comply with the State of Design's directives, hence, public consultation is not always required. The ADs are issued by authorised personnel within CASA, ensuring that the legislative process adheres to the statutory requirements outlined in the Act.
Key Provisions
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 outline the process for the issuance of airworthiness directives (ADs) under section 98 of the Act and regulation 39.001 of the Regulations. Section 39.001(5) further clarifies that an AD is considered a disallowable instrument under section 46A of the Acts Interpretation Act 1901 and is therefore a legislative instrument. This legislative framework is underpinned by the principles set forth in Annex 8 to the Convention on International Civil Aviation, which assigns the State of Design with the primary responsibility for the continuing airworthiness of aircraft types and mandates the provision of necessary information to States of Registry. In the context of Australia, the Civil Aviation Safety Authority (CASA) acts as the national airworthiness authority, responsible for assessing and issuing ADs based on the directives from the State of Design.
The obligations under the Act and Regulations require CASA to evaluate the airworthiness directives issued by the State of Design, in this case, the United States Federal Aviation Administration (FAA), concerning the Bell 412 model helicopters. As per Annex 8, the State of Registry, in this instance, CASA, must ensure that the continuing airworthiness of aircraft registered in Australia is maintained by developing or adopting requirements that align with the ADs. In this specific scenario, CASA has issued Australian AD/BELL 412/55, which will take effect on 21 May 2008, after assessing the FAA's AD 2008-10-03. This process ensures that Australian-registered Bell 412 helicopters comply with the safety standards set forth by the relevant State of Design.
The issuance of ADs, particularly those mandated by international agreements, does not require consultation with the Australian public. This exemption is due to the nature of the ADs, which are directly related to international safety standards and the responsibilities of the State of Design. Additionally, the Office of Best Practice Regulation has determined that ADs do not necessitate a Regulatory Impact Statement. This streamlined process ensures that safety directives can be implemented swiftly without undue bureaucratic delay. The AD was made by the Manager, Airframes in the Airworthiness Engineering Branch, on behalf of CASA, in accordance with subsection 84A(2) of the Act, ensuring that the directive adheres to the legislative requirements and standards.
Regarding the consequences for breaches of ADs, the Civil Aviation Act 1988 and associated regulations impose stringent obligations on aircraft operators and owners to comply with ADs. Failure to comply with an AD can lead to severe consequences, including potential civil penalties for non-compliance with airworthiness requirements. Under the Act, CASA has the authority to take enforcement actions against operators who do not adhere to ADs, which may include fines, suspension or revocation of aircraft certificates, or other regulatory actions. In serious cases, non-compliance can also result in criminal charges, leading to imprisonment if found guilty of contravening the Act or associated regulations. The specific penalties for breaches are determined based on the severity of the violation and the impact on aviation safety.
