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 310/14, affecting Cessna 310 series aircraft in 1967. CASA has reviewed this AD and as a result has decided to cancel it. The cancellation will become effective on 10 April 2008. No replacement AD is required, as the original unsafe condition no longer exists.
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 provide a legal framework for the regulation of civil aviation in Australia, aiming to ensure the safety and efficiency of air navigation and the continuing airworthiness of aircraft. The Act empowers the Governor-General to make regulations for these purposes, with the overarching goal of enhancing the safety of air navigation. One such regulation, under section 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. These ADs are legislative instruments that mandate compliance with airworthiness requirements as determined by the State of Design and, when necessary, the State of Registry. In line with international standards set out in Annex 8 to the Convention on International Civil Aviation, CASA plays a pivotal role in ensuring the continuing airworthiness of aircraft registered in Australia by issuing and managing ADs.
Scope and Application
The Civil Aviation Act 1988, through regulation 39.001 of the Civil Aviation Safety Regulations 1998, empowers the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific kinds of aircraft or aeronautical products. This regulation is designed to ensure the safety of air navigation in Australia, with CASA acting as the national airworthiness authority. Airworthiness directives are legislative instruments under the Acts Interpretation Act 1901 and the Legislative Instruments Act 2003, and they are integral to maintaining the continuing airworthiness of aircraft, as stipulated under Annex 8 to the Convention on International Civil Aviation. The State of Design holds primary responsibility for the airworthiness of an aircraft type, while the State of Registry is responsible for the airworthiness of individual aircraft, ensuring they meet necessary requirements. CASA must evaluate and, if appropriate, issue Australian ADs to enforce the requirements of the State of Design. This legislative framework ensures that Australian-registered aircraft meet international safety standards and that CASA can effectively manage the regulatory burden associated with airworthiness directives.
Key Provisions
The key provisions of the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 detail the process and authority for issuing airworthiness directives (ADs) (sections 98 and 39.001). These regulations allow the Civil Aviation Safety Authority (CASA) to mandate safety measures for specific types of aircraft or aeronautical products. An AD is a disallowable instrument, meaning it can be reviewed and potentially disallowed by Parliament, and it is considered a legislative instrument under the Legislative Instruments Act 2003 (subsection 39.001(5)). This regulatory framework ensures that the safety of air navigation is maintained in accordance with international standards set by the Convention on International Civil Aviation (Annex 8).
The obligations imposed by these provisions include the responsibility of the State of Design to ensure the continuing airworthiness of an aircraft type and to provide necessary information to the States of Registry. The State of Registry, in turn, must develop or adopt requirements to maintain the airworthiness of aircraft within its jurisdiction. In Australia, CASA, as the national airworthiness authority, must review ADs issued by the State of Design and, if necessary, issue an Australian AD to enforce these safety measures. This was exemplified in the issuance and subsequent cancellation of AD/CESSNA 310/14 for Cessna 310 series aircraft in 1967, where CASA determined that the original unsafe condition no longer existed, leading to the AD's cancellation effective 10 April 2008.
Failure to comply with ADs can result in serious consequences. The Act and Regulations do not explicitly detail offences, penalties, or civil/criminal consequences for non-compliance, but such actions can lead to severe regulatory scrutiny, potential grounding of non-compliant aircraft, and legal action under broader aviation safety laws. CASA has the authority to enforce compliance and can take action against operators who do not adhere to the mandated safety measures. The legislative instruments, including ADs, are designed to uphold the highest safety standards in the aviation industry, and non-compliance can result in substantial penalties and legal ramifications.
