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/PA-22/26 affecting Piper PA-22 aircraft. CASA has assessed this AD and as a result has cancelled Australian AD/PA-22/26. The cancellation will become effective on 5 June 2008. 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, Systems and New Technologies in the Airworthiness Engineering Branch, on behalf of CASA, in accordance with subsection 84A (2) of the Act.
Overview
The Civil Aviation Act 1988, enacted to ensure the safety of air navigation, authorises the Governor-General to establish regulations, including those that mandate airworthiness directives (ADs). Under the Civil Aviation Safety Regulations 1998, the Civil Aviation Safety Authority (CASA) is empowered to issue ADs, which are legislative instruments subject to disallowance under the Acts Interpretation Act 1901 and the Legislative Instruments Act 2003. ADs are a fundamental mechanism for maintaining the continuing airworthiness of aircraft, aligning with the responsibilities outlined in Annex 8 of the Convention on International Civil Aviation. Specifically, the State of Design must ensure the airworthiness of aircraft types and provide necessary information to States of Registry, which in turn are tasked with implementing measures to maintain airworthiness. CASA, as Australia’s national airworthiness authority, evaluates ADs issued by other States of Design and, if necessary, issues corresponding Australian ADs. In this context, CASA has cancelled Australian AD/PA-22/26 for Piper PA-22 aircraft, effective 5 June 2008, due to the resolution of the unsafe condition that originally prompted its issuance. This action complies with Australia’s international obligations under the Convention on International Civil Aviation, and as such, no public consultation or Regulatory Impact Statement was required. The AD cancellation was authorised by the Manager, Systems and New Technologies in the Airworthiness Engineering Branch, acting on behalf of CASA in accordance with the Act.
Scope and Application
The Civil Aviation Act 1988 applies to the regulation of civil aviation in Australia and encompasses a broad range of entities, including aircraft operators, pilots, maintenance personnel, and aviation service providers, as well as the Civil Aviation Safety Authority (CASA) itself, which is responsible for the administration and enforcement of the Act. The Act provides CASA with the authority to issue regulations, including airworthiness directives (ADs), to ensure the safety of air navigation. The Civil Aviation Safety Regulations 1998 further detail the regulatory framework, with regulation 39.001 allowing CASA to issue ADs for specific kinds of aircraft or aeronautical products, which are legislative instruments under the Legislative Instruments Act 2003. These ADs are subject to the oversight of the State of Design, which must provide necessary information to ensure the continuing airworthiness of aircraft types, while the State of Registry, in this case CASA, is responsible for implementing these directives within Australia. The scope of the Act is national, covering all civil aviation activities within Australian jurisdiction, and while it generally applies to all relevant entities, specific exclusions or exemptions are not detailed in the text provided.
Key Provisions
The Civil Aviation Act 1988, specifically under section 98, empowers the Governor-General to create regulations aimed at ensuring the safety of air navigation. One such regulation, 39.001 of the Civil Aviation Safety Regulations 1998, allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for certain types of aircraft or aeronautical products. These ADs, as outlined in subregulation 39.001(5), are considered disallowable instruments under section 46A of the Acts Interpretation Act 1901 and are classified as legislative instruments according to section 6 of the Legislative Instruments Act 2003. ADs play a crucial role in maintaining the continuing airworthiness of aircraft, as mandated by Annex 8 to the Convention on International Civil Aviation, where the State of Design bears responsibility for an aircraft type's airworthiness and must share necessary information with the States of Registry.
Under these regulations, CASA, as Australia's national airworthiness authority, is obligated to review and, if necessary, implement Australian ADs based on directives issued by the State of Design. This ensures that the continuing airworthiness of aircraft is maintained according to international standards. For instance, AD/PA-22/26, issued by CASA or its predecessors for Piper PA-22 aircraft, has been assessed and subsequently cancelled due to the resolution of the unsafe condition. This cancellation will take effect on 5 June 2008, with no replacement AD required as the identified issue no longer exists.
The process of issuing and cancelling ADs involves specific obligations for CASA, ensuring that they align with Australia's commitments under international agreements such as the Convention on International Civil Aviation. Since the cancellation of AD/PA-22/26 was due to the resolution of an international safety concern, no public consultation was deemed necessary. Additionally, the Office of Best Practice Regulation has determined that ADs do not require a Regulatory Impact Statement. The AD was issued by the Manager, Systems and New Technologies in the Airworthiness Engineering Branch on behalf of CASA, in accordance with subsection 84A(2) of the Act.
Any breaches of the Civil Aviation Act 1988 or the Civil Aviation Safety Regulations 1998 can lead to significant consequences. Offences under these regulations may result in both civil and criminal penalties. For instance, non-compliance with ADs can lead to substantial fines and, in severe cases, imprisonment. The maximum penalties can vary depending on the nature and severity of the breach but can include significant financial penalties for corporations and imprisonment for individuals, underscoring the importance of adhering to the regulations to maintain aviation safety standards.
