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 has issued AD 2006-0361-E affecting Eurocopter AS332 series helicopters. The EASA is the State of Design for these helicopters. CASA has assessed this AD and has issued Australian AD/S-PUMA/67, which will become effective on 4 December 2006.
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 regulate and oversee the safety and efficiency of civil aviation within Australia. The Act provides the legislative framework for the establishment of safety standards and regulations, and empowers the Civil Aviation Safety Authority (CASA) to implement and enforce these standards. The 1988 Act aims to ensure the safety of air navigation and to meet Australia’s obligations under international agreements such as the Convention on International Civil Aviation. One of the key mechanisms through which CASA exercises its regulatory powers is the issuance of airworthiness directives (ADs), as outlined in the Civil Aviation Safety Regulations 1998. This legislation enables CASA to mandate safety measures for aircraft registered in Australia, in response to directives issued by the aircraft’s State of Design, or in line with international safety standards. The issuance of ADs is a critical tool in maintaining the continuing airworthiness of aircraft, ensuring that all aircraft operating within Australian airspace meet stringent safety requirements.
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 and aeronautical products to ensure the safety of air navigation. This regulatory framework applies to all aircraft registered in Australia and any aeronautical products used in Australian airspace, including those manufactured both domestically and internationally. The geographic reach of these regulations extends across the entire Commonwealth of Australia, with CASA acting as the national airworthiness authority responsible for implementing and enforcing these directives. The ADs serve as a critical mechanism for ensuring that aircraft maintain their airworthiness and comply with safety standards established by both Australian and international regulatory bodies. The issuance of ADs, such as the recent Australian AD/S-PUMA/67 in response to an EASA directive for Eurocopter AS332 series helicopters, underscores the collaborative nature of international aviation safety standards and the role of CASA in translating these standards into enforceable mandates within Australia. Notably, these directives are developed in accordance with international conventions and do not require public consultation or a Regulatory Impact Statement, reflecting their urgent nature and the reliance on expert assessment.
Key Provisions
The Civil Aviation Safety Regulations 1998, under regulation 39.001, empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products (reg. 39.001(1)). These directives are legislative instruments, as stipulated by subregulation 39.001(5) and section 46A of the Acts Interpretation Act 1901 (reg. 39.001(5); s. 46A Acts Interpretation Act 1901). They are issued in response to safety concerns and are integral to ensuring the continuing airworthiness of aircraft types as outlined in Annex 8 to the Convention on International Civil Aviation.
The obligations imposed by these regulations require CASA to assess any ADs issued by the State of Design and, if deemed necessary, issue corresponding Australian ADs. For instance, the European Aviation Safety Agency (EASA) issued AD 2006-0361-E for Eurocopter AS332 series helicopters, and CASA responded by issuing Australian AD/S-PUMA/67. This process underscores the need for continuous oversight and the adaptation of international safety standards to the Australian context. CASA, as Australia’s national airworthiness authority, must ensure that all aircraft within its registry comply with the mandated safety requirements.
The Civil Aviation Safety Regulations 1998 do not require consultation with the public or a Regulatory Impact Statement for ADs, as they are issued in response to international obligations and safety concerns identified by the State of Design (Office of Regulatory Review). The ADs are developed by the Manager, New Technologies and Systems, within CASA’s Manufacturing, Certification and New Technologies Office, in accordance with subsection 84A(2) of the Act. Failure to comply with an AD may result in severe penalties, including civil or criminal sanctions, as stipulated in relevant sections of the Civil Aviation Act 1988. The specific penalties depend on the nature and severity of the non-compliance, with potential outcomes including fines and imprisonment.
