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 Civil Aviation Safety Authority or its predecessors issued AD/SWSA226/1 affecting Fairchild (Swearingen) SA226T model aeroplanes. CASA has assessed this AD and as a result has cancelled Australian AD/SWSA226/1. The cancellation will become effective on 4 June 2009. No replacement AD is required, as the unsafe condition no longer exists.
As this AD has been cancelled because of Australia’s obligations under the Convention on International Civil Aviation, no consultation with the Australian public has taken place on this AD cancellation. 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, Airframe and Structures, in the Airworthiness Engineering Group, 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 and ensure the safety and efficiency of air navigation. The Act empowers the Governor-General to make regulations for the purposes of the Act and in the interests of the safety of air navigation. The Civil Aviation Safety Regulations 1998, made under the authority of the Act, allow the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for kinds of aircraft or aeronautical products. These ADs are legislative instruments that mandate specific actions to ensure the continuing airworthiness of aircraft, as per the obligations under Annex 8 to the Convention on International Civil Aviation. In the case of the Fairchild (Swearingen) SA226T model aeroplanes, CASA issued and subsequently cancelled AD/SWSA226/1 due to the resolution of the unsafe condition, in line with Australia's obligations under the Convention and without the need for public consultation or a Regulatory Impact Statement.
Scope and Application
The Civil Aviation Act 1988, as amended by the Civil Aviation Safety Regulations 1998, governs the issuance of airworthiness directives (ADs) in Australia, aimed at ensuring the safety of air navigation. Under this framework, the Civil Aviation Safety Authority (CASA) can issue ADs for specific types of aircraft or aeronautical products. These ADs are legislative instruments that are subject to disallowance and must comply with the Legislative Instruments Act 2003. The State of Design, typically the manufacturer's country, holds the primary responsibility for the continuing airworthiness of an aircraft type, while the State of Registry, in this case Australia, must implement the requirements set forth by the State of Design to ensure that aircraft meet safety standards. In this context, CASA, as the national airworthiness authority, assesses foreign ADs and, if necessary, issues corresponding Australian ADs. For instance, CASA issued and subsequently cancelled the Australian AD/SWSA226/1 for Fairchild (Swearingen) SA226T model aeroplanes, reflecting the resolution of an identified unsafe condition. This process is conducted in accordance with Australia’s obligations under the Convention on International Civil Aviation, and thus does not require public consultation or a Regulatory Impact Statement.
Key Provisions
The Civil Aviation Act 1988, under section 98, empowers the Governor-General to make regulations for the safety of air navigation, while regulation 39.001 of the Civil Aviation Safety Regulations 1998 authorises CASA to issue airworthiness directives (ADs) for types of aircraft or aeronautical products. This regulatory framework ensures that ADs serve as essential tools for maintaining the safety and airworthiness of aircraft. Notably, subregulation 39.001(5) stipulates that ADs are disallowable instruments, classifying them as legislative instruments under section 6 of the Legislative Instruments Act 2003. The State of Design bears the responsibility for the continuing airworthiness of an aircraft type, as outlined in Annex 8 to the Convention on International Civil Aviation, and must provide necessary information to ensure the safety of aircraft registered in other states. Correspondingly, the State of Registry must develop or adopt requirements to ensure the continuing airworthiness of aircraft within its jurisdiction. This international regulatory cooperation is crucial for maintaining consistent safety standards across different jurisdictions.
Compliance with ADs is mandatory for all entities governed by the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998. The Civil Aviation Safety Authority (CASA) plays a pivotal role in this process by assessing information provided by the State of Design and issuing Australian ADs as necessary to mandate safety requirements. For instance, when CASA assessed the AD/SWSA226/1 affecting Fairchild (Swearingen) SA226T model aeroplanes, it determined that the unsafe condition had been rectified, leading to the cancellation of the Australian AD/SWSA226/1. This cancellation, effective from 4 June 2009, reflects CASA's commitment to ensuring the safety of aircraft registered in Australia. The process of issuing, assessing, and cancelling ADs is conducted in accordance with subsection 84A(2) of the Act, ensuring that CASA's actions align with legislative requirements.
The Act and the Regulations impose stringent obligations on various parties to ensure compliance with ADs. Aircraft owners, operators, and maintenance providers must adhere to the requirements set forth in ADs to maintain the airworthiness of their aircraft. Failure to comply with ADs can result in severe consequences, including the grounding of aircraft, revocation of airworthiness certificates, and legal penalties. CASA is tasked with enforcing compliance through regular inspections and audits, ensuring that all entities subject to the Act and Regulations meet their obligations. The Office of Best Practice Regulation has determined that ADs do not require a Regulatory Impact Statement, streamlining the process of issuing and enforcing these safety directives.
In terms of enforcement, breaches of ADs can lead to significant penalties. Under the Civil Aviation Act 1988, non-compliance with ADs can result in both civil and criminal penalties. Civil penalties may include fines, suspension or revocation of airworthiness certificates, and other administrative actions. Criminal penalties can include imprisonment, reflecting the seriousness with which the law views safety violations. The maximum penalties for such offences are determined by the severity of the breach and the impact on aviation safety. These measures underscore the importance of adhering to ADs and the potential consequences of failing to do so.
