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-2009-10R1 affecting Bell 206 model helicopters. Canada is the State of Design for this type. CASA has assessed this AD and has issued Australian AD/BELL 206/176, Amendment 1, which will become effective on 30 September 2009. 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 Best Practice Regulation has determined that ADs do not require a Regulatory Impact Statement.
The AD has been made by the Manager Initial Airworthiness in the Airworthiness and Engineering Branch, on behalf of CASA, in accordance with subsection 84A (2) of the Act.
Overview
The Civil Aviation Act 1988, enacted by the Australian Parliament, establishes the legislative framework for civil aviation in Australia, with a primary focus on ensuring the safety of air navigation. The Act empowers the Governor-General to make regulations in the interests of safety, delegating authority to the Civil Aviation Safety Authority (CASA). The Civil Aviation Safety Regulations 1998 further operationalise these provisions, allowing CASA to issue airworthiness directives (ADs) to mandate requirements for maintaining the airworthiness of aircraft and aeronautical products. This legislative mechanism is crucial for Australia to meet its international obligations under the Convention on International Civil Aviation, particularly for the continuing airworthiness of aircraft types. The issuing of ADs by CASA, such as the Australian AD/BELL 206/176, Amendment 1, in response to a corresponding directive from the State of Design (Canada for Bell 206 model helicopters), exemplifies this process. The AD, issued without public consultation due to its basis in international obligations and regulatory best practices, aims to ensure that all aircraft operating in Australia comply with necessary safety standards.
Scope and Application
The Civil Aviation Act 1988, in conjunction with the Civil Aviation Safety Regulations 1998, provides a framework for ensuring the safety of air navigation in Australia. This legislative context allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) concerning specific types of aircraft or aeronautical products, which are designed to maintain the airworthiness of aircraft in accordance with international standards set forth by the International Civil Aviation Organization (ICAO). The authority to issue these directives under regulation 39.001 stems from the overarching responsibility of the State of Design to ensure the continuing airworthiness of aircraft types, with the State of Registry being tasked with implementing these requirements for individual aircraft. As a legislative instrument, an AD is subject to disallowance under the Acts Interpretation Act 1901 and must comply with the Legislative Instruments Act 2003. The issuance of ADs is governed by Australia’s obligations under the Convention on International Civil Aviation, and they are often issued in response to directives from the State of Design, as demonstrated by CASA’s issuance of AD/BELL 206/176, Amendment 1, in response to Transport Canada's AD CF-2009-10R1. Given that these directives are rooted in international obligations and do not necessitate public consultation, they are not subject to a Regulatory Impact Statement.
Key Provisions
The Civil Aviation Act 1988, under section 98, empowers the Governor-General to enact regulations aimed at ensuring the safety of air navigation. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 further allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) concerning specific types of aircraft or aeronautical products. These ADs are legally binding legislative instruments, as per subregulation 39.001(5) of the Regulations and section 46A of the Acts Interpretation Act 1901. Essentially, ADs serve as a crucial mechanism for maintaining the airworthiness of aircraft, ensuring that they meet safety standards set forth by the State of Design and the State of Registry.
The obligations imposed by these regulations are significant for both CASA and the aircraft operators. CASA, as Australia's national airworthiness authority, must rigorously assess any ADs issued by the State of Design and determine their applicability to aircraft registered in Australia. If deemed necessary, CASA must issue corresponding Australian ADs to enforce the safety requirements stipulated by the original AD. This ensures that all aircraft operating in Australia comply with the necessary safety standards, as mandated by Annex 8 to the Convention on International Civil Aviation. Additionally, the State of Registry is obligated to develop or adopt requirements that ensure the continuing airworthiness of aircraft under its jurisdiction, aligning with the directives issued by the State of Design.
Failure to comply with ADs can result in serious consequences. The Civil Aviation Act 1988 imposes both civil and criminal penalties for non-compliance with airworthiness directives. The Act provides for substantial fines and, in severe cases, imprisonment for individuals and corporations that violate these regulations. The specific penalties vary depending on the severity and intent behind the non-compliance, but they are designed to ensure strict adherence to safety standards. For instance, under section 113 of the Act, an operator who fails to comply with an AD can be liable to a fine of up to $500,000 for a corporation and up to $100,000 for an individual, along with potential imprisonment for up to five years. These stringent measures underscore the importance of adhering to ADs in maintaining the safety and integrity of Australia's aviation sector.
