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/BEECH 55/6, affecting Beech 55 model aircraft in 1967. CASA has reviewed this AD and as a result has decided to cancel it. The cancellation will become effective on 5 June 2008. No replacement AD is required, as all affected aircraft would have been modified long ago.
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, enacted by the Australian Parliament, addresses various aspects of civil aviation, ensuring the safety and efficiency of air navigation within Australia. The Act provides a framework for the regulation of civil aviation and empowers the Governor-General to make regulations for the purposes of the Act, particularly focusing on the safety of air navigation. One such regulation, the Civil Aviation Safety Regulations 1998, allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for types of aircraft or aeronautical products. This mechanism is critical in maintaining the continuing airworthiness of aircraft as stipulated under Annex 8 to the Convention on International Civil Aviation. The Act and its associated regulations thus aim to safeguard public interest by ensuring that aircraft operating within Australian airspace meet stringent safety standards.
The cancellation of AD/BEECH 55/6, affecting Beech 55 model aircraft manufactured in 1967, exemplifies the application of the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 in practice. CASA, Australia’s national airworthiness authority, issued this AD in response to safety concerns and subsequently reviewed its necessity. The decision to cancel the AD was made due to the fact that all affected aircraft would have been modified long ago, reducing the regulatory burden without compromising safety. This action was taken under the authority conferred by the Act, specifically by the Manager, Airframes in the Airworthiness Engineering Branch, in accordance with subsection 84A(2) of the Act. No public consultation was required, as determined by the Office of Best Practice Regulation, which also confirmed that ADs do not necessitate a Regulatory Impact Statement.
Scope and Application
The Civil Aviation Safety Regulations 1998, under section 39.001, empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products, which are legislative instruments under the Acts Interpretation Act 1901. This legislative action is firmly rooted in the overarching objective of ensuring the safety of air navigation, as outlined in the Civil Aviation Act 1988. ADs are integral to maintaining the continuing airworthiness of aircraft, as mandated by Annex 8 to the Convention on International Civil Aviation, with the State of Design bearing primary responsibility for providing necessary information to the States of Registry, including Australia. CASA, as the national airworthiness authority, is tasked with assessing such information and issuing corresponding ADs for aircraft registered in Australia, if deemed necessary. For instance, AD/BEECH 55/6, which concerned Beech 55 model aircraft manufactured in 1967, was reviewed and subsequently cancelled by CASA, effective 5 June 2008, due to the aircraft already being modified as per the directive long ago. This cancellation does not necessitate public consultation or a Regulatory Impact Statement, given the reduction in regulatory burden it entails. The authority to issue such ADs is exercised by the Manager, Airframes in the Airworthiness Engineering Branch, on behalf of CASA, in compliance with the Civil Aviation Act 1988.
Key Provisions
The Civil Aviation Act 1988, through section 98, grants the Governor-General the authority to create regulations aimed at ensuring the safety of air navigation. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 further empowers the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. These ADs are essential for maintaining the continuing airworthiness of aircraft, and they are considered disallowable instruments under section 46A of the Acts Interpretation Act 1901. Consequently, as per section 6 of the Legislative Instruments Act 2003, ADs are classified as legislative instruments. Annex 8 to the Convention on International Civil Aviation assigns the State of Design with the overarching responsibility for the continuing airworthiness of an aircraft type, requiring them to provide necessary information to States of Registry. The State of Registry, in turn, must develop or adopt requirements to ensure the ongoing airworthiness of individual aircraft. When a State of Design issues an AD, CASA must evaluate this information and, if necessary, issue an Australian AD to enforce the requirements of the State of Design.
The obligations imposed by the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 on parties and entities are significant. The State of Design must ensure that aircraft types are airworthy and provide necessary information to States of Registry. This includes issuing ADs to address any safety concerns. The State of Registry must implement and enforce the requirements set out in these ADs for aircraft registered within their jurisdiction. CASA, as the national airworthiness authority, must review ADs issued by foreign States of Design and decide whether to issue corresponding Australian ADs. Additionally, CASA is responsible for monitoring compliance with these directives and ensuring that all aircraft meet the required safety standards. This involves conducting assessments, issuing necessary directives, and ensuring that affected parties are aware of and comply with the stipulated requirements.
Violations of the provisions outlined in the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 can result in various civil and criminal consequences. Failure to comply with an AD can lead to significant penalties, including fines and imprisonment. For example, under the Civil Aviation Act 1988, a person who contravenes a regulation can be fined up to 500 penalty units for an individual and up to 2,500 penalty units for a body corporate. Additionally, imprisonment for up to two years may be imposed for serious breaches. The severity of the penalties reflects the critical importance of adhering to ADs in maintaining the safety of air navigation. CASA has the authority to enforce these regulations, and non-compliance can result in enforcement actions, including legal proceedings and sanctions against the offending party.
