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 EASA issued AD 2006-0273 and 2006-0278 affecting EUROCOPTER AS 350 and EC 130 helicopters. The EASA is the State of Design for these helicopters. CASA has amended the equivalent Australian AD to AD/ECUREUIL/112 Amendment 1 which will become effective on 23 November 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 was enacted to provide a legal framework for the regulation of civil aviation in Australia, aiming to ensure the safety and efficiency of air navigation and operations. The Act grants the Governor-General the authority to make regulations under section 98, facilitating the oversight of airworthiness and safety standards. The Civil Aviation Safety Regulations 1998, in particular, empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific aircraft or aeronautical products, aligning with the requirements under Annex 8 of the Convention on International Civil Aviation. This legislative framework ensures that CASA, as Australia's national airworthiness authority, can mandate necessary safety measures in response to directives issued by the State of Design, thereby fulfilling Australia's international obligations and maintaining the safety standards of aircraft registered in Australia.
Scope and Application
The Civil Aviation Act 1988, as supplemented by the Civil Aviation Safety Regulations 1998, applies to entities involved in civil aviation within Australia, including aircraft manufacturers, operators, and maintenance providers. The Act grants the Civil Aviation Safety Authority (CASA) the authority to issue airworthiness directives (ADs) to ensure the continuing airworthiness of aircraft registered in Australia. ADs are legislative instruments that are issued in response to safety concerns identified by the State of Design or in compliance with international aviation standards, such as Annex 8 to the Convention on International Civil Aviation. These regulations extend to all aircraft types registered in Australia, mandating compliance with safety directives issued by CASA. The ADs are applicable nationally and are designed to harmonise with international safety standards. Although ADs are not subject to public consultation or a Regulatory Impact Statement, they are rigorously assessed by CASA to ensure they meet necessary safety requirements. The application and enforcement of these regulations are overseen by CASA, which acts on behalf of the Australian government to maintain air safety standards.
Key Provisions
The main operative sections of this legislation include section 98 of the Civil Aviation Act 1988, which allows the Governor-General to make regulations in the interests of air navigation safety, and regulation 39.001 of the Civil Aviation Safety Regulations 1998, which empowers the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. This AD, specifically AD/ECUREUIL/112 Amendment 1, pertains to EUROCOPTER AS 350 and EC 130 helicopters. It mandates that CASA, Australia’s national airworthiness authority, must review and, if necessary, implement ADs issued by the State of Design, which in this case is the European Aviation Safety Agency (EASA). The AD, which replaces its previous version, will become effective on 23 November 2006.
The obligations imposed by the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 require CASA to ensure the continuing airworthiness of aircraft registered in Australia. This includes assessing ADs issued by the State of Design and implementing equivalent Australian ADs when necessary. CASA must act in accordance with international standards set by the Convention on International Civil Aviation, particularly Annex 8, which stipulates that the State of Design has the primary responsibility for the continuing airworthiness of an aircraft type and must provide necessary information to the State of Registry. CASA must then develop or adopt requirements to maintain airworthiness based on this information. For the helicopters in question, CASA has amended the Australian AD to reflect the EASA’s directives.
The AD itself includes specific instructions for maintaining the airworthiness of the EUROCOPTER AS 350 and EC 130 helicopters, which must be complied with by the aircraft operators and owners. These instructions will likely include maintenance schedules, inspection requirements, and other technical specifications necessary to ensure the safety of the aircraft. Operators must adhere to these requirements to maintain their aircraft's airworthiness certification. Failure to comply with the AD could result in the aircraft being grounded or losing its airworthiness certification.
The legislation does not specify criminal or civil penalties for non-compliance with the ADs. However, non-compliance with airworthiness directives can have severe consequences, including the potential for aircraft accidents, which could lead to criminal charges under other sections of the Civil Aviation Act 1988 or related aviation safety laws. Additionally, operators who fail to comply with ADs may face enforcement actions from CASA, such as fines or the suspension or revocation of their air operator certificate. The severity of these consequences underscores the importance of adhering to the ADs to ensure the safety of air navigation.
