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/TPE 331/22 affecting Honeywell TPE 331 engines in 1977. CASA has reviewed this AD and as a result has cancelled it. The cancellation will become effective on 24 September 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, Future Technology and Regulatory Trends, in the Standards Development and Future Technology Division, on behalf of CASA, in accordance with subsection 84A (2) of the Act.
Overview
The Civil Aviation Act 1988 was enacted to provide a comprehensive legal framework for the regulation of civil aviation within Australia. This Act aims to ensure the safety and efficiency of air navigation and aircraft operations. Under section 98 of the Act, the Governor-General is empowered to make regulations for the purposes of the Act, particularly in relation to the safety of air navigation. In line with these provisions, the Civil Aviation Safety Regulations 1998 were established, which grant the Civil Aviation Safety Authority (CASA) the authority to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. These ADs serve as legislative instruments and are subject to disallowance under the Acts Interpretation Act 1901. The Civil Aviation Safety Regulations 1998 reflect Australia’s commitments under Annex 8 to the Convention on International Civil Aviation, which assigns the State of Design a primary role in ensuring the continuing airworthiness of aircraft types and mandates the provision of necessary information to the States of Registry. CASA has the responsibility to develop or adopt requirements to maintain the airworthiness of aircraft within Australia, aligning with these international standards.
Scope and Application
The Civil Aviation Safety Regulations 1998, as an instrument of the Civil Aviation Act 1988, govern the safety of air navigation in Australia, extending their application to all aircraft registered in the country and the aeronautical products used within it. Regulation 39.001 specifically empowers the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for certain types of aircraft and aeronautical products, ensuring the safety standards are maintained in line with international obligations under the Convention on International Civil Aviation. These directives are legislative instruments and can be subject to disallowance as per the Acts Interpretation Act 1901. Although the issuance and cancellation of ADs are integral to maintaining airworthiness, the specific AD/TPE 331/22 affecting Honeywell TPE 331 engines, cancelled due to alignment with international obligations, did not require public consultation or a Regulatory Impact Statement, reflecting the streamlined approach to such regulatory adjustments. The AD cancellation process is overseen by CASA, ensuring compliance with both national and international aviation safety standards.
Key Provisions
The key sections of the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 that are pertinent to the issuance of airworthiness directives (ADs) are section 98 of the Act (1) and regulation 39.001 of the Regulations (2). Section 98 allows the Governor-General to make regulations in the interests of air navigation safety, and regulation 39.001 enables the Civil Aviation Safety Authority (CASA) to issue ADs for specific kinds of aircraft or aeronautical products. The ADs are considered legislative instruments under section 6 of the Legislative Instruments Act 2003 (3).
The obligations imposed by the Act and the Regulations on the relevant parties are multifaceted. The State of Design has the overarching responsibility for the continuing airworthiness of an aircraft type and must provide necessary information to the States of Registry (4). The State of Registry is responsible for ensuring the continuing airworthiness of individual aircraft and must develop or adopt requirements to achieve this (5). CASA, as the regulatory body, is tasked with issuing ADs to maintain these standards (6).
In terms of consequences for non-compliance, the Act and Regulations do not explicitly outline specific offences or penalties related to the breach of ADs. However, given the critical nature of airworthiness directives in ensuring safety, non-compliance could potentially lead to severe repercussions, including legal actions under other provisions of the Civil Aviation Act 1988 or related safety regulations. Additionally, CASA has the authority to enforce compliance and may take appropriate actions against entities that fail to adhere to ADs, which could include fines, operational restrictions, or other regulatory measures (7).
There are no specific maximum penalties stated in the provided text for breaches of ADs, but the potential for enforcement actions by CASA suggests that non-compliance could result in significant repercussions for the entities involved. The issuance and enforcement of ADs are critical to maintaining the high safety standards required in the aviation industry.
