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/BELL 206/31 affecting Bell 206A model aircraft. CASA has assessed this AD and as a result has cancelled it. The cancellation will become effective on 23 October 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 Group, on behalf of CASA, in accordance with subsection 84A (2) of the Act.
Overview
The Civil Aviation Act 1988, enacted by the Commonwealth Parliament, aims to provide a regulatory framework for ensuring the safety and efficiency of civil aviation in Australia. One of the mechanisms introduced by this Act is the regulation of airworthiness directives (ADs), which are critical for maintaining the continuing airworthiness of aircraft and aeronautical products. Section 98 of the Act empowers the Governor-General to make regulations, including ADs, for the safety of air navigation. The Civil Aviation Safety Regulations 1998 further delineate the process by which the Civil Aviation Safety Authority (CASA) can issue these directives. This legislative framework is designed to ensure that Australia meets its international obligations under the Convention on International Civil Aviation, particularly concerning the responsibilities of the State of Design and State of Registry for ensuring the safety and airworthiness of aircraft. The ADs are a direct response to the need for consistent and enforceable safety measures across the aviation industry, aligning with the overarching policy objective of protecting public safety and maintaining high standards of aviation safety.
Scope and Application
The Civil Aviation Safety Regulations 1998, under the authority of the Civil Aviation Act 1988, empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific kinds of aircraft or aeronautical products. These directives are integral to ensuring the continuing airworthiness of aircraft, with CASA playing a pivotal role as Australia's national airworthiness authority. ADs are legislative instruments that align with international standards, particularly those outlined in Annex 8 to the Convention on International Civil Aviation, which stipulates that the State of Design has the overarching responsibility for an aircraft type's airworthiness and must provide necessary information to the States of Registry. The State of Registry, in turn, must ensure the continuing airworthiness of individual aircraft within its jurisdiction. This regulatory framework ensures that ADs issued by other states are appropriately assessed and, if necessary, mirrored by CASA to maintain safety standards. The Act and Regulations extend their jurisdiction to all aircraft registered in Australia, regardless of the State of Design, thereby establishing a comprehensive and internationally consistent approach to air safety.
Key Provisions
The Civil Aviation Act 1988, in section 98, grants the Governor-General the authority to create regulations that contribute to the safety of air navigation. This power is exercised through the Civil Aviation Safety Regulations 1998, particularly in regulation 39.001, which empowers the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs). These ADs are crucial as they apply to specific types of aircraft or aeronautical products. It's important to note that under subregulation 39.001(5), an AD is classified as a disallowable instrument as per the Acts Interpretation Act 1901, and therefore, according to section 6 of the Legislative Instruments Act 2003, an AD is considered a legislative instrument. The international obligations under Annex 8 to the Convention on International Civil Aviation dictate that the State of Design of an aircraft type has the overarching responsibility for ensuring its continuing airworthiness and must provide necessary information to the States of Registry to maintain this airworthiness.
Under these international standards, the State of Registry for an individual aircraft bears the responsibility for its ongoing airworthiness. The State of Registry is required to develop or adopt regulations that ensure the continuing airworthiness of the aircraft. When a State of Design issues an AD for a type of aircraft that is registered in Australia, CASA must review this information. If deemed necessary, CASA, as Australia’s national airworthiness authority, must issue an Australian AD that enforces the requirements of the State of Design. This process was exemplified in the issuance and subsequent cancellation of AD/BELL 206/31, which affected Bell 206A model aircraft. CASA assessed the AD and decided to cancel it, effective from 23 October 2008, as the unsafe condition it addressed no longer existed. No replacement AD was required.
The obligations imposed by the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 require CASA to act diligently in the interest of safety, ensuring that all ADs are carefully reviewed and implemented where necessary. CASA must liaise with international bodies to maintain consistency and compliance with international standards. Additionally, the authority has to ensure that any AD issued is based on thorough assessment and is necessary for maintaining airworthiness. The cancellation of AD/BELL 206/31 demonstrates CASA's commitment to ensuring that regulations are responsive to the actual safety conditions of aircraft types registered in Australia.
The legislation also outlines potential consequences for non-compliance. While the specific offences, penalties, or civil and criminal consequences are not detailed in the provided text, it is understood that failure to adhere to airworthiness directives can result in serious repercussions. These may include fines, imprisonment, or other penalties that could affect both individuals and corporations involved in aviation operations. The seriousness of these consequences underscores the critical importance of compliance with ADs and the overarching regulatory framework designed to ensure the safety of air navigation.
