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.
CASA issued AD/CESSNA 320/16, affecting Cessna 320 series aircraft in 1971. CASA has reviewed this AD and as a result has decided to cancel it. The cancellation will become effective on 17 January 2008. No replacement AD is required, as the original unsafe condition is now addressed by AD/GENERAL/74 Amendment 1.
No consultation with the Australian public has taken place on this AD cancellation, because the cancellation results in a reduction of the regulatory burden. 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 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 address the need for comprehensive regulation of civil aviation within Australia, aiming to ensure the safety and efficiency of air navigation. The Act provides the legal framework for the Australian Civil Aviation Safety Authority (CASA) to implement safety regulations and directives. In 1998, the Civil Aviation Safety Regulations were introduced under the authority of the Act, allowing CASA to issue airworthiness directives for types of aircraft or aeronautical products. These directives are crucial for maintaining the continuing airworthiness of aircraft and ensuring compliance with international standards set by the International Civil Aviation Organization (ICAO). CASA’s authority to issue such directives is derived from regulation 39.001 of the Civil Aviation Safety Regulations 1998, and these directives are considered legislative instruments under the Acts Interpretation Act 1901 and the Legislative Instruments Act 2003. The Act empowers CASA to act on behalf of the Australian government to manage and mitigate aviation safety risks, thereby protecting the public and maintaining the integrity of the national airspace system.
Scope and Application
The Civil Aviation Act 1988, as supplemented by the Civil Aviation Safety Regulations 1998, provides the legislative framework for the regulation of airworthiness directives (ADs) in Australia. The Act applies to the issuance of ADs by the Civil Aviation Safety Authority (CASA), which is the national airworthiness authority responsible for ensuring the continuing airworthiness of aircraft registered in Australia. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 empowers CASA to issue ADs for specific types of aircraft or aeronautical products. These ADs are legislative instruments, subject to disallowance under section 46A of the Acts Interpretation Act 1901 and legislative oversight as per the Legislative Instruments Act 2003. The ADs are issued in accordance with international standards set by the Convention on International Civil Aviation, particularly Annex 8, which delineates the responsibilities of the State of Design and the State of Registry in maintaining airworthiness. The scope of the ADs is thus limited to the types of aircraft and aeronautical products registered in Australia, and they aim to address safety issues identified by the relevant State of Design. In the specific case of AD/CESSNA 320/16, which affected the Cessna 320 series aircraft from 1971, CASA has decided to cancel the directive due to the resolution of the original safety concern by another AD, resulting in a reduction of regulatory burden without the need for public consultation or a Regulatory Impact Statement.
Key Provisions
The Civil Aviation Act 1988, through section 98, empowers the Governor-General to create regulations aimed at ensuring the safety of air navigation. This includes the issuance of airworthiness directives (ADs) under regulation 39.001 of the Civil Aviation Safety Regulations 1998, which allows the Civil Aviation Safety Authority (CASA) to mandate safety measures for specific types of aircraft or aeronautical products. According to subregulation 39.001(5), these ADs are considered disallowable instruments under section 46A of the Acts Interpretation Act 1901 and are classified as legislative instruments by the Legislative Instruments Act 2003. These directives serve as a means for the State of Design to maintain the continuing airworthiness of an aircraft type, ensuring compliance with Annex 8 of the Convention on International Civil Aviation.
The obligations imposed by the Civil Aviation Safety Regulations 1998 on the State of Design and the State of Registry are significant. The State of Design, which is responsible for the continuing airworthiness of an aircraft type, must provide all necessary information to the appropriate States of Registry to ensure the safety of aircraft in operation. The State of Registry, in turn, is tasked with developing or adopting requirements to maintain the airworthiness of individual aircraft. When CASA, acting as Australia's national airworthiness authority, receives an AD from the State of Design, it must evaluate the information and, if necessary, issue an Australian AD to enforce the safety measures stipulated by the State of Design.
Failure to comply with the airworthiness directives can result in serious consequences. While the Civil Aviation Act 1988 does not specify detailed penalties for non-compliance with ADs, general provisions within the Act allow for civil and criminal penalties. For example, section 170 of the Act outlines that any person who contravenes an AD may be liable to a fine of up to $105,000 for an individual or $525,000 for a body corporate, depending on the severity of the breach. Additionally, CASA can take enforcement actions, including the suspension or revocation of an aircraft's certificate of airworthiness, which can significantly impact the operation and safety of the aircraft.
The legislative framework governing ADs is designed to ensure that all stakeholders, from the State of Design to the State of Registry, adhere to stringent safety standards. The Civil Aviation Safety Regulations 1998 mandate that CASA must issue ADs when necessary, and the Civil Aviation Act 1988 provides the authority to impose penalties for non-compliance. This regulatory approach aims to maintain the highest standards of air safety and to protect the public from potential hazards associated with aircraft operations.
