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.
Transport Canada has issued AD CF-2000-11 affecting Bell 427 helicopters. Canada is the State of Design for these helicopters. CASA has assessed this AD and has issued Australian AD/BELL 427/4, which will become effective on 11 May 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, enacted to regulate civil aviation within Australia and ensure the safety of air navigation, empowers the Governor-General to establish regulations for the Act's purposes and the safety of air navigation. Under this legislative framework, the Civil Aviation Safety Regulations 1998 were established, allowing the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. These directives are considered legislative instruments and are subject to disallowance as stipulated in the Acts Interpretation Act 1901 and the Legislative Instruments Act 2003. The policy objective of this Act and its associated regulations is to maintain and ensure the safety and continuing airworthiness of aircraft in accordance with international standards set by the Convention on International Civil Aviation.
In response to international obligations and directives from the State of Design, CASA issues corresponding ADs to ensure compliance and safety standards within Australia. For instance, following an airworthiness directive issued by Transport Canada for Bell 427 helicopters, CASA assessed the information and issued its own directive, AD/BELL 427/4, effective from 11 May 2006. This process underscores CASA’s role in maintaining airworthiness in line with international standards and obligations.
Scope and Application
The Civil Aviation Act 1988, supplemented by the Civil Aviation Safety Regulations 1998, provides the legislative framework for the regulation of civil aviation safety in Australia. This Act applies to any person or entity involved in the operation, maintenance, or design of aircraft within Australian airspace, as well as to the manufacture and distribution of aeronautical products. The jurisdictional reach of the Act is national, given that it pertains to the Commonwealth of Australia and its obligations under international agreements, such as the Convention on International Civil Aviation. The Act mandates that the Civil Aviation Safety Authority (CASA) must ensure the continuing airworthiness of aircraft registered in Australia, including issuing airworthiness directives (ADs) that are necessary to maintain safety standards. ADs are legislative instruments that become effective following the assessment and issuance by CASA, often in response to directives issued by the State of Design of the aircraft in question. For instance, an AD issued by Transport Canada for Bell 427 helicopters would necessitate CASA's assessment and subsequent issuance of an Australian AD. It is notable that the issuance of such directives does not require public consultation or a Regulatory Impact Statement, as determined by the Office of Regulatory Review. This streamlined process ensures that CASA can promptly address safety concerns as dictated by international obligations and the requirements of the State of Design.
Key Provisions
The Civil Aviation Safety Regulations 1998, particularly regulation 39.001, empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) concerning specific types of aircraft or aeronautical products. These directives are crucial for ensuring the continuing airworthiness of aircraft as mandated by international standards, particularly under Annex 8 to the Convention on International Civil Aviation. For example, CASA has issued AD/BELL 427/4 in response to an airworthiness directive issued by Transport Canada concerning Bell 427 helicopters, which are designed by Canada. This process is guided by Australia’s commitments under international aviation agreements, and it reflects the necessity for harmonised safety standards across jurisdictions.
The obligations under the Civil Aviation Safety Regulations 1998 necessitate that CASA, as Australia’s national airworthiness authority, rigorously assess any ADs issued by States of Design and determine their applicability to aircraft registered in Australia. In the case of the AD/BELL 427/4, CASA has evaluated the information provided by Canada and, finding it appropriate, has mandated the requirements specified in the Canadian AD for Australian-registered Bell 427 helicopters. This includes ensuring that all relevant stakeholders are informed and that any necessary actions are taken to comply with the new safety directives. The State of Registry must therefore implement these directives to maintain the continuing airworthiness of the aircraft.
Failure to comply with the requirements of an AD can result in severe legal consequences. Under the Civil Aviation Act 1988, non-compliance with an AD may be considered an offence. The Act provides for various penalties, which may include fines and imprisonment. Specifically, under section 24 of the Act, a person who contravenes an AD may be liable to a penalty of up to $126,000 for an individual and $630,000 for a body corporate, depending on the severity of the breach. Additionally, CASA may take enforcement actions, including grounding the aircraft until compliance is achieved. The precise penalties and enforcement measures are detailed in the regulations and may vary based on the specific circumstances of the violation.
