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/BELL 47/91 affecting Bell 47 model aircraft. CASA has reviewed this AD and as a result has cancelled it. The cancellation will become effective on 12 February 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, Systems and New Technologies 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 Australian Parliament, establishes a framework for ensuring the safety of air navigation within Australia. It grants the Governor-General the authority to create regulations that are essential for the safety of air navigation, as stated in section 98. The Civil Aviation Safety Regulations 1998 further delegate specific responsibilities to the Civil Aviation Safety Authority (CASA), including the power to issue airworthiness directives (ADs) for certain types of aircraft or aeronautical products, as outlined in regulation 39.001. This legislation seeks to address the need for stringent safety measures in civil aviation to protect public safety and comply with international standards.
The cancellation of AD/BELL 47/91, which affected Bell 47 model aircraft, was necessitated by Australia's obligations under the Convention on International Civil Aviation. As a result, CASA reviewed and subsequently cancelled this directive, effective from 12 February 2009, without the need for a replacement. This action was taken without public consultation, as determined by the Office of Best Practice Regulation, which concluded that ADs do not require a Regulatory Impact Statement. The cancellation was executed by the Manager, Systems and New Technologies in the Airworthiness Engineering Group on behalf of CASA, in compliance with the Civil Aviation Act 1988.
Scope and Application
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) concerning kinds of aircraft or aeronautical products. These directives, which are legislative instruments, are integral to maintaining the safety standards and continuing airworthiness of aircraft, as stipulated by Annex 8 of the Convention on International Civil Aviation. The State of Design, which is the country where the aircraft is designed, holds primary responsibility for the ongoing airworthiness of an aircraft type and must share necessary information with the State of Registry, which is the country where the aircraft is registered. The State of Registry must then implement or adopt measures to ensure the continuing airworthiness of the aircraft. In the context of this particular regulation, CASA or its predecessors had previously issued AD/BELL 47/91 for Bell 47 model aircraft, but this directive has been cancelled due to Australia’s obligations under the Convention on International Civil Aviation and will become effective as of 12 February 2009, without necessitating a replacement directive. This cancellation did not require public consultation or a Regulatory Impact Statement, and the directive was made by the Manager, Systems and New Technologies in the Airworthiness Engineering Group, on behalf of CASA, in accordance with the Act.
Key Provisions
The Civil Aviation Act 1988 provides the legal framework for ensuring the safety of air navigation in Australia. Specifically, section 98 empowers the Governor-General to create regulations, including airworthiness directives (ADs), to enhance safety (s. 98). Regulation 39.001 of the Civil Aviation Safety Regulations 1998 further authorises the Civil Aviation Safety Authority (CASA) to issue ADs for specific aircraft or aeronautical products (reg. 39.001). These ADs are legislative instruments under the Acts Interpretation Act 1901 and the Legislative Instruments Act 2003 (s. 46A; s. 6).
CASA’s role under these provisions is to ensure that ADs are issued in accordance with international standards. As the State of Registry, Australia is responsible for the continuing airworthiness of individual aircraft, while the State of Design has overarching responsibility for the airworthiness of aircraft types (Annex 8, Convention on International Civil Aviation). The State of Design must provide necessary information to States of Registry to maintain airworthiness. ADs serve as a critical means of disseminating this information.
The obligations placed on CASA and other entities governed by these provisions include the issuance and enforcement of ADs to maintain safety standards. CASA must ensure that ADs are compliant with international obligations and reflect the latest safety requirements. The State of Registry must implement and enforce ADs to ensure the airworthiness of aircraft registered within Australia. Both States of Design and Registry are responsible for ensuring that ADs are issued and adhered to, facilitating the safe operation of aircraft.
The Civil Aviation Act 1988 and associated regulations impose penalties for non-compliance with ADs. Violation of an AD can result in both civil and criminal consequences. Civil penalties can include fines and, in some cases, revocation of aircraft certificates. Criminal penalties can include imprisonment, reflecting the seriousness of non-compliance with safety regulations. The exact penalties depend on the nature and severity of the breach but are designed to ensure strict adherence to safety standards.
In summary, the Civil Aviation Act 1988 and Civil Aviation Safety Regulations 1998 establish a framework for issuing and enforcing ADs to maintain the safety of air navigation in Australia. CASA, as the regulatory authority, is responsible for issuing these directives in line with international standards and national obligations. The State of Registry must ensure compliance with ADs to maintain airworthiness. Penalties for non-compliance are severe, underscoring the importance of adhering to safety regulations.
