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, the Civil Aviation Safety Authority (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.
CASA or its predecessors issued AD/PA-46/8 affecting Piper PA-46-310P aircraft. CASA has reviewed this AD and as a result has cancelled it. The cancellation will become effective on 9 April 2009. No replacement AD is required.
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 Group, on behalf of CASA, in accordance with subsection 84A (2) of the Act.
Overview
The Civil Aviation Act 1988 was enacted to establish a framework for the regulation of civil aviation in Australia, ensuring safety and efficiency in air navigation. The Act empowers the Governor-General to make regulations that support the Act's objectives, including the issuance of airworthiness directives (ADs) through the Civil Aviation Safety Regulations 1998. This legislation aims to align Australia's civil aviation practices with international standards and obligations, particularly under the Convention on International Civil Aviation. The Civil Aviation Safety Authority (CASA), acting under these regulations, issues ADs to maintain the continuing airworthiness of aircraft and aeronautical products. These directives are critical for ensuring that aircraft meet safety standards and comply with international obligations. The authority to issue and cancel ADs is vested in CASA, with the recent cancellation of AD/PA-46/8 affecting Piper PA-46-310P aircraft exemplifying CASA's commitment to fulfilling Australia's international commitments and maintaining stringent safety standards without the need for public consultation or a Regulatory Impact Statement.
Scope and Application
The Civil Aviation Act 1988, supplemented by the Civil Aviation Safety Regulations 1998, provides the framework under which airworthiness directives (ADs) are issued to ensure the safety of air navigation in Australia. The Act empowers the Governor-General to make regulations for the safety of air navigation, and regulation 39.001 of the Civil Aviation Safety Regulations 1998 grants the Civil Aviation Safety Authority (CASA) the authority to issue ADs for specific types of aircraft or aeronautical products. This regulatory approach is consistent with Australia's obligations under Annex 8 to the Convention on International Civil Aviation, which assigns the State of Design the responsibility for the continuing airworthiness of aircraft types and mandates the provision of necessary information to States of Registry. The State of Registry, in this case CASA, is tasked with ensuring the continuing airworthiness of individual aircraft by implementing or adopting relevant requirements. This legislative structure facilitates the coordination of airworthiness directives across national and international jurisdictions to maintain uniform safety standards.
Key Provisions
Under the Civil Aviation Act 1988, and specifically section 98, the Governor-General is empowered to make regulations to ensure the safety of air navigation. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 enables the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for particular types of aircraft or aeronautical products. These directives, detailed in subregulation 39.001(5), are considered disallowable instruments under section 46A of the Acts Interpretation Act 1901, and thus, legislative instruments in accordance with section 6 of the Legislative Instruments Act 2003. ADs play a crucial role in maintaining the continuing airworthiness of aircraft types, as outlined in Annex 8 to the Convention on International Civil Aviation, where the State of Design is tasked with providing necessary information to ensure this airworthiness. The State of Registry, which is the country where the aircraft is registered, also has the responsibility of ensuring the continuing airworthiness of the aircraft by developing or adopting appropriate requirements.
The obligations under the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 require CASA to issue ADs as necessary to maintain safety standards. These obligations extend to ensuring that any AD issued complies with Australia’s international obligations under the Convention on International Civil Aviation. For example, CASA issued AD/PA-46/8, which affected Piper PA-46-310P aircraft, and has since reviewed and cancelled this directive. The cancellation, effective from 9 April 2009, means that no replacement AD is necessary. This decision aligns with the State of Registry’s responsibility to ensure the continuing airworthiness of the aircraft, and it was made in accordance with the authority granted by subsection 84A(2) of the Act.
In terms of regulatory compliance and public consultation, the Office of Best Practice Regulation has determined that ADs do not require a Regulatory Impact Statement. Consequently, no consultation with the Australian public has been conducted concerning the cancellation of AD/PA-46/8. This decision reflects the specific nature of ADs as technical safety measures rather than broader policy instruments. Furthermore, the legislative process for issuing and cancelling ADs is streamlined, allowing CASA to act swiftly in response to safety concerns or changes in international standards. The authority to issue ADs and the procedures for their cancellation are critical in maintaining the safety and airworthiness of aircraft operating within Australian airspace.
Offences and penalties for non-compliance with ADs are significant. Operators who fail to comply with an AD may face substantial penalties. Under the Civil Aviation Act 1988, an operator who contravenes an AD commits an offence. The maximum penalty for such an offence can include fines and, in severe cases, imprisonment. These provisions underscore the importance of adhering to ADs to ensure the safety of air navigation. CASA’s role in issuing and managing ADs is therefore not only a regulatory function but also a vital safety measure to protect the public and aviation personnel. The consequences of non-compliance highlight the seriousness with which the Australian aviation regulatory framework treats safety directives.
