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-31/103 affecting Piper PA-31T and T1 aircraft. CASA has reviewed this AD and as a result has cancelled it. The cancellation will become effective on 31 July 2008. 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 Branch, on behalf of CASA, in accordance with subsection 84A (2) of the Act.
Overview
The Civil Aviation Act 1988 was enacted to regulate the safety of civil aviation in Australia, establishing the framework for ensuring the safety of air navigation and aircraft. Under section 98 of this Act, the Governor-General has the authority to make regulations for the Act's purposes, thereby promoting the safety of air navigation. The Civil Aviation Safety Regulations 1998 further empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products, as stipulated under regulation 39.001. This legislative structure addresses the need for stringent safety measures and regulatory oversight in the civil aviation sector to align with international standards and obligations, such as those outlined in Annex 8 to the Convention on International Civil Aviation. The Act and accompanying regulations ensure that both the State of Design and the State of Registry are held accountable for the continuing airworthiness of aircraft, thereby fostering a robust safety regime.
Scope and Application
The Civil Aviation Safety Regulations 1998, which include the provision for airworthiness directives, apply to aircraft and aeronautical products within Australia and are enforced by the Civil Aviation Safety Authority (CASA). These regulations are designed to ensure the safety of air navigation in accordance with the Civil Aviation Act 1988, with CASA having the authority to issue airworthiness directives for specified kinds of aircraft or aeronautical products. Airworthiness directives serve as a critical tool for maintaining the continuing airworthiness of aircraft as mandated by Annex 8 to the Convention on International Civil Aviation, which assigns the State of Design with the responsibility for ensuring the ongoing airworthiness of an aircraft type and requires the State of Registry to adopt or develop requirements to ensure the same. The cancellation of a specific airworthiness directive, such as AD/PA-31/103 affecting Piper PA-31T and T1 aircraft, is governed by these international obligations and does not necessitate public consultation or a Regulatory Impact Statement. The cancellation is issued by the Manager, Systems and New Technologies in the Airworthiness Engineering Branch on behalf of CASA, reflecting the legislative framework under which CASA operates.
Key Provisions
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 together provide the legal framework for the regulation of civil aviation safety in Australia. Section 98 of the Act empowers the Governor-General to make regulations for the safety of air navigation, while regulation 39.001 allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. These directives are legislative instruments, subject to disallowance under the Acts Interpretation Act 1901 and reviewed under the Legislative Instruments Act 2003. The State of Design is responsible for the continuing airworthiness of an aircraft type, and must share necessary information with States of Registry, who are responsible for the airworthiness of individual aircraft.
The obligations imposed by these regulations require CASA to monitor and ensure the safety of aircraft in Australia. CASA must issue ADs to address any safety issues identified with particular types of aircraft, ensuring that these directives are in line with international standards set by the Convention on International Civil Aviation. The State of Registry must adopt or develop requirements to maintain the continuing airworthiness of aircraft under its jurisdiction, and the State of Design must provide relevant information to support this. CASA's role includes reviewing, amending, or cancelling ADs as circumstances change or new information becomes available. The cancellation of AD/PA-31/103 for Piper PA-31T and T1 aircraft is a practical example of this, reflecting Australia's adherence to international obligations.
Failing to comply with an airworthiness directive can lead to significant legal consequences. Under the Civil Aviation Act 1988, non-compliance with an AD can result in substantial fines and, in severe cases, criminal charges. The maximum penalty for corporations can reach up to $1,215,000, while individuals can face penalties of up to $243,000. Additionally, non-compliance can lead to the grounding of aircraft, which can have serious operational and safety implications. CASA has the authority to enforce these penalties and take necessary actions to ensure compliance with safety regulations.
