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 77/15 Amendment 1 affecting Beechcraft 77 model aircraft. CASA has assessed this AD and as a result has cancelled Australian AD/BEECH 77/15 Amendment 1. 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 was enacted to provide a comprehensive legal framework for the regulation of civil aviation in Australia, ensuring the safety, efficiency, and orderly growth of civil aviation. This Act grants the Governor-General the authority to make regulations under section 98, which includes the issuance of airworthiness directives (ADs) as per regulation 39.001 of the Civil Aviation Safety Regulations 1998. The Civil Aviation Safety Authority (CASA) issues these ADs, which are legislative instruments subject to disallowance, as mandated by section 46A of the Acts Interpretation Act 1901 and the Legislative Instruments Act 2003. These directives are essential for maintaining the continuing airworthiness of aircraft and are issued in accordance with Annex 8 of the Convention on International Civil Aviation, which outlines the responsibilities of the State of Design and State of Registry in ensuring aircraft safety. The Act aims to align Australia's civil aviation practices with international standards, ensuring the safety of air navigation within Australia and globally.
Scope and Application
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 provide the legislative framework for the issuance and management of airworthiness directives (ADs) in Australia. These regulations apply to the continuing airworthiness of aircraft registered in Australia and the aeronautical products used in these aircraft. The Civil Aviation Safety Authority (CASA), acting as Australia’s national airworthiness authority, is responsible for issuing ADs to ensure compliance with safety standards and regulations. ADs are legislative instruments that mandate specific requirements for maintaining the airworthiness of aircraft types, and they must be adhered to by aircraft operators and owners. The State of Design has the primary responsibility for issuing ADs based on international standards and practices, while the State of Registry, in this case CASA, assesses and implements these directives as necessary. The ADs are subject to disallowance, and their issuance and cancellation follow specific legislative procedures, ensuring that they are aligned with Australia’s obligations under international civil aviation conventions.
Key Provisions
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 establish the framework for ensuring the safety of air navigation in Australia. Under section 98 of the Civil Aviation Act 1988, the Governor-General is empowered to make regulations for the Act's purposes, particularly for the safety of air navigation. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. An AD is considered a legislative instrument under the Legislative Instruments Act 2003, meaning it is subject to disallowance under section 46A of the Acts Interpretation Act 1901.
The obligations imposed by these regulations require CASA to issue ADs based on assessments of information provided by the State of Design, which holds responsibility for the continuing airworthiness of an aircraft type as outlined in Annex 8 to the Convention on International Civil Aviation. The State of Registry, in this case CASA, must ensure the continuing airworthiness of aircraft registered in Australia. When an AD is issued by a State of Design, CASA must assess its relevance and, if appropriate, issue a corresponding AD for Australian-registered aircraft. This process ensures that safety standards are consistently maintained and that any identified unsafe conditions are addressed promptly.
In this particular instance, CASA issued and subsequently cancelled Australian AD/BEECH 77/15 Amendment 1, which pertained to Beechcraft 77 model aircraft. The cancellation of this AD took place due to Australia’s obligations under the Convention on International Civil Aviation, and it was determined that the unsafe condition no longer existed, thus no replacement AD was necessary. The AD cancellation became effective on 3 July 2008. Given the nature of this AD cancellation, no public consultation was required, and the Office of Best Practice Regulation confirmed that it does not necessitate a Regulatory Impact Statement.
Failure to comply with ADs can result in significant legal consequences. Section 120 of the Civil Aviation Act 1988 imposes strict penalties for non-compliance. Any person who contravenes an AD may be subject to a civil penalty of up to $11,100 for individuals and $55,500 for corporations, as outlined in section 120(1). Additionally, under section 120(2), failure to comply with an AD can lead to criminal penalties, including fines of up to $111,000 for individuals and $555,000 for corporations, and imprisonment for up to two years for individuals and five years for corporations. These stringent measures underscore the importance of adhering to airworthiness directives to ensure the safety of air navigation.
