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-25/16 Amdt 2 affecting Piper PA-25 aircraft. CASA has reviewed this AD and as a result has cancelled it. The cancellation will become effective on 20 November 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, Airframes 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, enacted by the Parliament of Australia, establishes the framework for civil aviation safety and regulation. One of the key mechanisms for ensuring the safety of aircraft in Australian airspace is the issuance of airworthiness directives (ADs), which are detailed in the Civil Aviation Safety Regulations 1998. The Civil Aviation Safety Authority (CASA), acting under these regulations, can issue ADs to address safety issues concerning specific types of aircraft or aeronautical products. The Civil Aviation Act 1988 empowers the Governor-General to create these regulations in the interest of air navigation safety. CASA's role in issuing ADs is critical to maintaining the continuing airworthiness of aircraft, aligning with international obligations under the Convention on International Civil Aviation, particularly the responsibilities of the State of Design and the State of Registry. In this context, CASA has recently cancelled a specific AD affecting Piper PA-25 aircraft, reflecting Australia’s commitment to international safety standards and obligations.
Scope and Application
The Civil Aviation Act 1988, as supplemented by the Civil Aviation Safety Regulations 1998, provides the legal framework for the issuance of airworthiness directives (ADs) in Australia, which are legislative instruments aimed at ensuring the safety of air navigation. Under regulation 39.001, the Civil Aviation Safety Authority (CASA) is empowered to issue ADs for specific types of aircraft or aeronautical products. This authority is exercised by the Manager, Airframes and Structures in the Airworthiness Engineering Group, on behalf of CASA. Importantly, ADs fall within the category of disallowable instruments under the Acts Interpretation Act 1901 and are treated as legislative instruments pursuant to the Legislative Instruments Act 2003. These directives serve as a critical mechanism for maintaining the continuing airworthiness of aircraft, aligning with the international standards set by Annex 8 to the Convention on International Civil Aviation. The State of Registry of an aircraft bears the responsibility for ensuring its continuing airworthiness, in accordance with international obligations. The recent cancellation of AD/PA-25/16 Amdt 2, affecting Piper PA-25 aircraft, exemplifies how CASA adheres to these international obligations, leading to the cancellation of an existing directive without the need for public consultation or a Regulatory Impact Statement.
Key Provisions
The key operative sections of the Civil Aviation (Safety) Regulations 1998, specifically regulation 39.001, allow the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for certain types of aircraft or aeronautical products (39.001(1)). These directives are essential for ensuring the ongoing airworthiness of the specified aircraft and products. Subregulation 39.001(5) states that ADs are considered disallowable instruments under section 46A of the Acts Interpretation Act 1901, and as such, they are legislative instruments under section 6 of the Legislative Instruments Act 2003 (39.001(5)). This means that ADs carry legal weight and are subject to the regulations governing legislative instruments.
The obligations imposed by these regulations primarily rest on CASA and the State of Registry of an individual aircraft. CASA has the responsibility to issue ADs that comply with international standards set forth in Annex 8 to the Convention on International Civil Aviation. The State of Registry must then ensure that the aircraft it registers meets the continuing airworthiness requirements, which include adhering to the ADs issued by CASA. This division of responsibilities is crucial for maintaining safety standards in the aviation industry, as it ensures that both the design and operational aspects of aircraft are regulated by the appropriate authorities.
Breaching the requirements set out in the Civil Aviation Safety Regulations 1998 can result in both civil and criminal consequences. For example, failing to comply with an AD can lead to the grounding of an aircraft, which can have severe operational and financial implications for operators. In more serious cases, violations of these regulations can result in fines or imprisonment. The maximum penalties for breaches of these regulations are determined by the severity of the offence and can vary widely depending on the specific circumstances. For instance, under section 23 of the Civil Aviation Act 1988, an individual who fails to comply with an AD may face fines up to $50,400 for a corporation and up to $10,080 for an individual, along with potential imprisonment terms. These penalties are intended to enforce compliance and ensure the safety of air navigation.
