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 European Aviation Safety Authority (EASA) has issued AD 2006-0067 affecting Diamond DA40 aircraft. EASA is the responsible authority for this aircraft. CASA has assessed this AD and has issued Australian AD/DA40/4 Amendment 1, which will become effective on 8 June 2006. 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, New Technologies and Systems, 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, enacted by the Australian Parliament, governs the safety and regulation of civil aviation within Australia. This Act empowers the Governor-General to make regulations for the purposes of the Act, ensuring the safety of air navigation. One such regulation, the Civil Aviation Safety Regulations 1998, specifically allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for types of aircraft or aeronautical products. These ADs serve as a legislative instrument under the Acts Interpretation Act 1901, aiming to uphold the highest standards of aviation safety as mandated by international agreements such as Annex 8 to the Convention on International Civil Aviation. The objective of these directives is to ensure the continuing airworthiness of aircraft, thereby safeguarding the safety of air navigation within Australia.
Scope and Application
The Civil Aviation Safety Regulations 1998, under the Civil Aviation Act 1988, empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. This regulatory framework is designed to uphold the safety of air navigation and is in line with Australia's obligations under the Convention on International Civil Aviation. ADs are legislative instruments, subject to disallowance and oversight as stipulated in the Acts Interpretation Act 1901 and the Legislative Instruments Act 2003 respectively. The State of Design holds the primary responsibility for the continuing airworthiness of aircraft types and must share necessary information with the States of Registry, which in Australia's case, is CASA. This regulatory process ensures that Australian ADs align with international standards and requirements set by the relevant State of Design, such as the European Aviation Safety Authority (EASA). Consequently, CASA issued AD/DA40/4 Amendment 1, which mandates compliance with EASA's AD 2006-0067 for Diamond DA40 aircraft registered in Australia, effective from 8 June 2006. This AD replaces its predecessor, reflecting ongoing obligations to international civil aviation standards and safety protocols.
Key Provisions
The main operative sections of the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998, as exemplified in this particular case, empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) (s 98; reg 39.001). An AD is essentially a formal instruction issued by CASA to mandate compliance with safety standards and ensure the airworthiness of specific types of aircraft or aeronautical products. As per subregulation 39.001(5), ADs are classified as disallowable instruments under section 46A of the Acts Interpretation Act 1901, making them legislative instruments as per section 6 of the Legislative Instruments Act 2003. This particular instance involves CASA issuing an AD for Diamond DA40 aircraft in response to an AD issued by the European Aviation Safety Authority (EASA), the responsible authority for this aircraft type.
The obligations imposed by the Act and Regulations on the parties or entities it governs are primarily centred around ensuring the safety and airworthiness of aircraft. For CASA, this involves assessing information from the State of Design and, if appropriate, issuing an Australian AD to mandate the requirements. The State of Design, in this case EASA, has the responsibility to provide any necessary information to ensure the continuing airworthiness of the aircraft type. The State of Registry, here being Australia, must then develop or adopt requirements to ensure the continuing airworthiness of the aircraft registered within its jurisdiction. Furthermore, the Act and Regulations underscore international obligations under the Convention on International Civil Aviation, where the State of Design has overall responsibility for the continuing airworthiness of an aircraft type.
The issuance of ADs is critical in maintaining safety standards and ensuring that all aircraft meet the required airworthiness criteria. CASA's assessment and subsequent issuance of the Australian AD/DA40/4 Amendment 1 is a direct response to the AD 2006-0067 issued by EASA. This process ensures that the safety measures and compliance requirements are uniformly applied across international borders, adhering to the international standards set by ICAO. Given that this AD is issued under Australia's obligations under the Convention on International Civil Aviation, and in response to an AD raised by the relevant State of Design, no public consultation is required, as determined by the Office of Regulatory Review. This AD has been made by the Manager, New Technologies and Systems, in the Manufacturing, Certification and New Technologies Office, on behalf of CASA, in accordance with subsection 84A(2) of the Act.
Any breach of the requirements set forth by the ADs could result in severe consequences. Non-compliance with ADs can lead to safety hazards, potentially resulting in accidents or incidents. The Civil Aviation Act 1988 and associated regulations may include specific provisions for offences, penalties, or civil/criminal consequences for non-compliance. Although the specific penalties are not detailed in this context, typically, breaches can result in fines, imprisonment, or both, depending on the severity of the non-compliance and its impact on safety. The overarching aim is to ensure that all stakeholders adhere to the stringent safety standards, thereby safeguarding air travel and maintaining the integrity of the aviation industry.
