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, 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. When a State of Design issues an AD against a type of aircraft on the Australian Register, CASA, as Australia’s national airworthiness authority, must assess that information and, if appropriate, issue an Australian AD to mandate the requirements of the State of Design.
The Civil Aviation Safety Authority or its predecessors issued AD/BEECH 65/9 affecting Beechcraft 65 model aircraft. CASA has assessed this AD and as a result has cancelled Australian AD/BEECH 65/9. The cancellation will become effective on 3 July 2008. No replacement AD is required, as the unsafe condition no longer exists.
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, enacted by the Parliament of Australia, serves as a foundational statute governing the regulation of civil aviation in Australia. This Act was introduced to ensure the safety and efficiency of civil aviation within Australia, establishing a regulatory framework that includes the issuance of airworthiness directives to maintain the continuing airworthiness of aircraft. The Civil Aviation Safety Regulations 1998, which are subsidiary legislation made under the authority of the Act, provide further detail on the processes and requirements for ensuring aircraft safety, including the mechanisms for issuing and cancelling airworthiness directives. These regulations empower the Civil Aviation Safety Authority (CASA) to issue directives based on international standards and practices, particularly those set by the International Civil Aviation Organization (ICAO). The policy objective of these regulations is to align Australian practices with international norms, thereby enhancing the overall safety of civil aviation in Australia and maintaining its international obligations.
Scope and Application
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 provide the framework for the issuance of airworthiness directives (ADs) within Australia, ensuring the safety of air navigation. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 empowers the Civil Aviation Safety Authority (CASA) to issue ADs for specific kinds of aircraft or aeronautical products. These ADs serve as legislative instruments and are subject to disallowance under the Acts Interpretation Act 1901. The ADs are aligned with the standards set forth in Annex 8 to the Convention on International Civil Aviation, which mandates that the State of Design, typically the manufacturer, retains responsibility for the continuing airworthiness of an aircraft type. CASA, as Australia's national airworthiness authority, evaluates this information and may issue corresponding Australian ADs to enforce the requirements set by the State of Design. The AD/BEECH 65/9, affecting Beechcraft 65 model aircraft, was assessed by CASA and subsequently cancelled due to the resolution of the unsafe condition, without the need for a replacement directive. This cancellation was made in accordance with the Act, without public consultation or the requirement for a Regulatory Impact Statement.
Key Provisions
The Civil Aviation Act 1988 provides the legislative framework for ensuring the safety of air navigation, and under section 98, the Governor-General has the authority to make regulations to this end. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 specifically empowers the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for particular types of aircraft or aeronautical products. These ADs are designed to ensure the ongoing safety and airworthiness of aircraft in service. Furthermore, subregulation 39.001(5) stipulates that an AD is a disallowable instrument under the Acts Interpretation Act 1901, and by virtue of section 6 of the Legislative Instruments Act 2003, an AD is classified as a legislative instrument.
The obligations imposed by the Civil Aviation Act and the Civil Aviation Safety Regulations on the parties involved are significant. The State of Design, which is typically the country where the aircraft was designed, has the primary responsibility for ensuring the continuing airworthiness of an aircraft type. This includes providing necessary information to States of Registry to help them maintain the airworthiness of individual aircraft. The State of Registry, which is the country where an aircraft is registered, is responsible for implementing the requirements necessary to maintain the airworthiness of aircraft within its jurisdiction. When a State of Design issues an AD, CASA, as Australia’s national airworthiness authority, must review this information and, if necessary, issue an Australian AD to enforce the requirements.
Failure to comply with ADs can have serious legal consequences. Section 97 of the Civil Aviation Act 1988, among other provisions, outlines the penalties for non-compliance with airworthiness regulations, including ADs. While specific penalties for breaches of ADs are not detailed in the Civil Aviation Act, non-compliance with airworthiness requirements generally can result in substantial fines and potential imprisonment. CASA has the authority to enforce compliance through various means, including fines, suspension of airworthiness certificates, and other regulatory actions. These measures are critical to maintaining the high safety standards required in civil aviation.
Additionally, CASA’s role in issuing and cancelling ADs, as seen in the case of AD/BEECH 65/9 affecting Beechcraft 65 model aircraft, demonstrates the dynamic nature of airworthiness regulation. CASA assessed the AD and determined that the unsafe condition no longer existed, leading to the cancellation of the AD on 3 July 2008. This process reflects CASA’s commitment to safety and its responsiveness to international obligations under the Convention on International Civil Aviation. The decision to cancel the AD was made without public consultation, as determined by the Office of Best Practice Regulation, which concluded that ADs do not require a Regulatory Impact Statement. The authority to issue such directives is exercised by the Manager, Systems and New Technologies in the Airworthiness Engineering Branch on behalf of CASA, in accordance with the provisions of the Civil Aviation Act 1988.
