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 407 model helicopters. Canada is the State of Design for this type. CASA has assessed this AD and has issued Australian AD/BELL 407/32, 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 was enacted to regulate civil aviation in Australia with a primary focus on safety and efficiency. This legislation grants the authority to make regulations, such as the Civil Aviation Safety Regulations 1998, which empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs). These directives, which are legislative instruments, are issued to ensure the continuing airworthiness of aircraft and aeronautical products in line with international standards, particularly those outlined in Annex 8 to the Convention on International Civil Aviation. The Civil Aviation Safety Regulations 1998, particularly regulation 39.001, provide CASA with the authority to mandate such directives when necessary. The ADs are a response to Australia’s obligations under international conventions and are issued in accordance with the safety and regulatory frameworks established by the Civil Aviation Act 1988 and other relevant regulations.
Scope and Application
The Civil Aviation Act 1988, as supplemented by the Civil Aviation Safety Regulations 1998, outlines the framework under which airworthiness directives (ADs) are issued to ensure the safety of air navigation. Specifically, regulation 39.001 of the Civil Aviation Safety Regulations 1998 empowers the Civil Aviation Safety Authority (CASA) to issue ADs for certain types of aircraft or aeronautical products, making them legislative instruments under section 46A of the Acts Interpretation Act 1901. These ADs are critical for maintaining the continuing airworthiness of aircraft, a responsibility primarily held by the State of Design but enforced by the State of Registry, which, in Australia's case, is CASA. For instance, in response to Transport Canada's AD CF-2009-10R1 affecting Bell 407 model helicopters, CASA issued Australian AD/BELL 407/32, Amendment 1, effective from 30 September 2009. This directive cancels and replaces the previous issue, reflecting Australia's commitment to international standards set forth by the Convention on International Civil Aviation. Given the international nature of these directives, no public consultation has been deemed necessary, and the Office of Best Practice Regulation has determined that ADs do not require a Regulatory Impact Statement. The issuance of such ADs is conducted by the Manager Initial Airworthiness in the Airworthiness and Engineering Branch, on behalf of CASA, in accordance with the Act.
Key Provisions
The main operative sections of the Civil Aviation Safety Regulations 1998 relevant to this AD include section 39.001, which allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for kinds of aircraft or aeronautical products. Specifically, subregulation 39.001(5) states that an AD is a disallowable instrument under section 46A of the Acts Interpretation Act 1901, and therefore a legislative instrument according to section 6 of the Legislative Instruments Act 2003. The AD issued by CASA is Australian AD/BELL 407/32, Amendment 1, which mandates certain requirements for Bell 407 model helicopters registered in Australia.
The obligations and requirements imposed by this AD on the parties governed by it are primarily centred around ensuring the continuing airworthiness of the Bell 407 model helicopters. The AD mandates specific actions or modifications that must be carried out by operators of these helicopters to maintain their airworthiness. For instance, it may require inspections, repairs, or other maintenance actions to be performed within a certain timeframe. Operators must comply with these directives to ensure that their aircraft meet the necessary safety standards. CASA, as the national airworthiness authority, has the responsibility to monitor compliance with these requirements and may conduct inspections or audits to ensure adherence to the AD.
The Civil Aviation Safety Regulations 1998 and the Civil Aviation Act 1988 provide for various offences and penalties for breaches of ADs. Failure to comply with an airworthiness directive can lead to serious safety risks and may result in enforcement actions. In the case of non-compliance, CASA can issue a Notice of Civil Penalty, which may lead to fines. The maximum penalty for contravening an AD can be substantial, reflecting the seriousness of the potential safety implications. For individuals, the maximum penalty may be up to $222,200, while for bodies corporate, the penalty can be significantly higher, reaching up to $1,111,100. These penalties underscore the importance of adhering to ADs to maintain aviation safety.
