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 2005-21-02 affecting MD Helicopters model 369 helicopters. The USA is the State of Design for this type. CASA has assessed this AD and has issued Australian AD/HU 369/113, Amendment 1, which will become effective on 7 December 2005. This AD cancels and replaces the previous issue.
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 Regulatory Review has determined that ADs do not require a Regulatory Impact Statement.
The AD has been made by the Manager, Airframes in the Manufacturing, Certification and New Technologies Office, on behalf of CASA, in accordance with subsection 84A (2) of the Act.
Overview
The Civil Aviation Act 1988 was enacted to provide for the regulation of civil aviation in Australia, with a focus on ensuring safety and efficiency in air navigation. The Act allows the Governor-General to make regulations for these purposes, as seen in the Civil Aviation Safety Regulations 1998. One such regulation is the issuance of airworthiness directives (ADs) by the Civil Aviation Safety Authority (CASA), which is mandated to maintain the continuing airworthiness of aircraft registered in Australia. This is in line with international standards under Annex 8 of the Convention on International Civil Aviation, where the State of Design is responsible for the continuing airworthiness of an aircraft type. CASA's role is to assess and, where necessary, issue Australian ADs to enforce the requirements set by the State of Design, ensuring compliance with both national and international safety standards.
Scope and Application
The Civil Aviation Safety Regulations 1998 apply to all aircraft registered in Australia and any aeronautical products used on such aircraft. This includes both domestic and international flights operating within Australian airspace, and any aircraft owned or operated by Australian entities abroad. The regulations are administered by the Civil Aviation Safety Authority (CASA) and apply under the authority of the Civil Aviation Act 1988. CASA has the power to issue airworthiness directives (ADs) which are binding instruments aimed at ensuring the safety of air navigation. These ADs can mandate specific maintenance, repair, or operational requirements for particular types of aircraft or aeronautical products. Importantly, ADs are considered legislative instruments under the Legislative Instruments Act 2003 and must be assessed and approved in accordance with Australia's obligations under the Convention on International Civil Aviation. ADs are often issued in response to safety issues identified by the State of Design or other contracting states, meaning that they may be implemented without public consultation. However, they are subject to disallowance by Parliament under section 46A of the Acts Interpretation Act 1901.
Key Provisions
The Civil Aviation Act 1988 (section 98) empowers the Governor-General to create regulations to ensure the safety of air navigation, which is a foundational provision that allows the creation of the regulatory framework under which airworthiness directives (ADs) are issued. The Civil Aviation Safety Regulations 1998 (regulation 39.001) specifically grant the Civil Aviation Safety Authority (CASA) the authority to issue ADs for types of aircraft or aeronautical products. This regulatory authority is crucial for maintaining the safety standards required under international aviation agreements, such as Annex 8 to the Convention on International Civil Aviation. Subregulation 39.001(5) further clarifies that ADs are considered disallowable instruments under section 46A of the Acts Interpretation Act 1901, and thus, they are legislative instruments in their own right. This legal status underpins the authority and legitimacy of ADs within the Australian regulatory framework.
The obligations imposed by the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 extend to both the State of Design and the State of Registry of an aircraft. The State of Design, in this case, the USA, has the responsibility to ensure the continuing airworthiness of the MD Helicopters model 369 helicopters and to issue necessary ADs to address safety issues. CASA, acting as Australia's national airworthiness authority, must then assess these ADs and, if appropriate, issue corresponding Australian ADs to enforce the requirements within the Australian aviation context. This process ensures that all aircraft registered in Australia meet the necessary safety standards, thereby fulfilling the obligations under international aviation agreements and maintaining the safety of air navigation within Australia.
The consequences of non-compliance with ADs are significant. While the specific civil or criminal penalties are not detailed in the provided text, the overarching legislative framework indicates that breaches of airworthiness directives can result in serious legal consequences. Given that ADs are legislative instruments, failure to comply with them can lead to enforcement actions by CASA, which may include fines, suspension, or revocation of airworthiness certificates, and potentially criminal charges. These potential outcomes underscore the importance of adhering to ADs to ensure the safety and regulatory compliance of aircraft operating in Australia.
