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/R22/33 affecting Robinson R22 helicopters equipped with removable tail rotor pedals. CASA has reviewed this AD and as a result has cancelled it. The cancellation will become effective on 7 May 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, 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, seeks to ensure the safety of air navigation within the country. One aspect of this is the issuance of airworthiness directives (ADs) to maintain the continuing airworthiness of aircraft, a responsibility that falls to the Civil Aviation Safety Authority (CASA) under regulation 39.001 of the Civil Aviation Safety Regulations 1998. These ADs are legislative instruments, disallowable under section 46A of the Acts Interpretation Act 1901, and subject to the requirements of the Legislative Instruments Act 2003. The ADs are crucial for compliance with Annex 8 to the Convention on International Civil Aviation, which places the responsibility for continuing airworthiness on the State of Design and the State of Registry. In the specific case of AD/R22/33 affecting Robinson R22 helicopters, CASA has cancelled the directive due to Australia's international obligations, with no public consultation or Regulatory Impact Statement required as per the Office of Best Practice Regulation's assessment.
The cancellation of AD/R22/33 was carried out by the Manager, Airframes and Structures in the Airworthiness Engineering Group on behalf of CASA, in accordance with the provisions of the Civil Aviation Act. This action underscores the importance of international standards in shaping domestic aviation safety regulations, demonstrating Australia's commitment to maintaining high safety standards while adhering to global conventions.
Scope and Application
The Civil Aviation Act 1988, in conjunction with the Civil Aviation Safety Regulations 1998, provides the legislative framework for issuing airworthiness directives (ADs) in Australia. Under these provisions, the Civil Aviation Safety Authority (CASA) is empowered to issue ADs for specific types of aircraft or aeronautical products, aimed at ensuring the safety of air navigation. This authority extends to the issuance of ADs as legislative instruments, which are subject to disallowance under the Acts Interpretation Act 1901 and the Legislative Instruments Act 2003. The ADs are integral to maintaining the continuing airworthiness of aircraft types, a responsibility primarily vested in the State of Design and the State of Registry. For example, CASA issued and subsequently cancelled AD/R22/33 concerning Robinson R22 helicopters with removable tail rotor pedals, reflecting Australia's obligations under the Convention on International Civil Aviation. This process does not require public consultation or a Regulatory Impact Statement, underscoring the technical nature of such directives. The AD cancellation is effective from 7 May 2009, and no replacement AD is deemed necessary.
Key Provisions
The Civil Aviation Act 1988 and its associated regulations, particularly the Civil Aviation Safety Regulations 1998, establish a framework for the regulation of civil aviation in Australia, focusing on the safety of air navigation. Section 98 of the Act allows the Governor-General to make regulations, which includes the issuance of airworthiness directives (ADs) by the Civil Aviation Safety Authority (CASA) under regulation 39.001. These directives, as outlined in subregulation 39.001(5), are legislative instruments subject to disallowance under section 46A of the Acts Interpretation Act 1901 and are governed by the Legislative Instruments Act 2003. This regulatory approach ensures that ADs are issued to maintain the continuing airworthiness of aircraft and aeronautical products, adhering to international standards set by the International Civil Aviation Organization (ICAO) under Annex 8 to the Convention on International Civil Aviation.
The obligations imposed by the Act and the Regulations are significant for both CASA and the States of Registry. CASA, as the regulatory authority, must issue ADs to ensure that aircraft and aeronautical products remain airworthy. This involves conducting reviews and assessments to determine when an AD is necessary, as seen in the issuance and subsequent cancellation of AD/R22/33 for Robinson R22 helicopters. States of Registry are also responsible for the continuing airworthiness of individual aircraft, requiring them to develop or adopt requirements that align with international standards and domestic regulations. This includes ensuring compliance with ADs, which serve as a primary tool for maintaining airworthiness.
Non-compliance with airworthiness directives can lead to severe consequences, as the primary objective of these regulations is to ensure the safety of air navigation. While the specific offences and penalties are not detailed in the provided text, it is understood that breaches of ADs or any regulations made under the Civil Aviation Act 1988 can result in civil or criminal liabilities. These may include fines, imprisonment, or other penalties as prescribed by relevant legislation. The seriousness of these consequences underscores the importance of adhering to ADs and the regulatory requirements set forth by CASA and the States of Registry.
The process of issuing and cancelling ADs, as demonstrated with AD/R22/33, reflects the dynamic nature of aviation safety regulation. CASA's cancellation of AD/R22/33 due to Australia's obligations under the Convention on International Civil Aviation indicates that ADs are subject to international standards and may be adjusted in response to changes in those standards or new information. The lack of public consultation and the determination that ADs do not require a Regulatory Impact Statement by the Office of Best Practice Regulation highlight the procedural efficiency in addressing airworthiness issues. Ultimately, the regulations and directives aim to maintain the highest safety standards in civil aviation, ensuring the protection of passengers, crew, and the public.
