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 56/28, affecting Beech 56 model aircraft in 1988. 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, all affected aircraft would have been inspected, and, if necessary 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 was enacted by the Australian Parliament to establish a comprehensive regulatory framework for civil aviation in Australia, addressing the need for a unified and effective system to ensure the safety and efficiency of air navigation. One of the significant provisions of this Act is the authority granted to the Governor-General to make regulations necessary for the safety of air navigation, as highlighted in section 98. The Civil Aviation Safety Regulations 1998 further elaborate on these provisions, specifically under regulation 39.001, which empowers the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for certain types of aircraft or aeronautical products. These ADs are integral to maintaining the continuing airworthiness of aircraft and are considered legislative instruments under the Legislative Instruments Act 2003. The Act and its associated regulations align with international standards, particularly those outlined in Annex 8 to the Convention on International Civil Aviation, ensuring that Australia’s aviation safety practices are consistent with global norms. The policy objective of these provisions is to safeguard the safety and airworthiness of aircraft operating within Australian airspace.
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 specified kinds of aircraft or aeronautical products. These ADs serve as legislative instruments and are integral to ensuring the continuing airworthiness of aircraft registered in Australia, aligning with the responsibilities outlined in Annex 8 to the Convention on International Civil Aviation. The State of Design retains overall responsibility for the continuing airworthiness of an aircraft type and must supply necessary information to the States of Registry, including Australia, to ensure compliance with airworthiness standards. CASA, acting as Australia's national airworthiness authority, is obligated to evaluate this information and, when necessary, issue Australian ADs to enforce the requirements stipulated by the State of Design. For instance, CASA previously issued AD/BEECH 56/28 concerning Beech 56 model aircraft in 1988, which has now been cancelled, effective 5 June 2008, due to the completion of necessary inspections and modifications on all affected aircraft. The cancellation of this AD, which reduces regulatory burden, did not necessitate public consultation nor a Regulatory Impact Statement, as determined by the Office of Best Practice Regulation. The AD cancellation was executed by the Manager, Airframes, in the Airworthiness Engineering Branch, on behalf of CASA, in accordance with subsection 84A(2) of the Civil Aviation Act 1988.
Key Provisions
The main operative sections of the Civil Aviation Act 1988 (the Act) and the Civil Aviation Safety Regulations 1998 (the Regulations) allow the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) under regulation 39.001 of the Regulations. These ADs are issued to ensure the continuing airworthiness of aircraft types, as mandated by the State of Design, which is the State responsible for the aircraft type. CASA, as Australia’s national airworthiness authority, must then assess this information and, if appropriate, issue an Australian AD to mandate the requirements of the State of Design. Section 84A(2) of the Act outlines the process under which CASA can issue these ADs.
The obligations and requirements imposed by the Act and the Regulations are multifaceted. Firstly, the State of Design has the primary responsibility for ensuring the continuing airworthiness of an aircraft type, including providing necessary information to the State of Registry, which in this case is Australia. CASA, as the State of Registry, must assess any ADs issued by the State of Design and, if appropriate, issue corresponding ADs in Australia. These ADs must be aligned with international standards as stipulated by Annex 8 to the Convention on International Civil Aviation. CASA must also ensure that all affected aircraft are inspected and, if necessary, modified to meet the airworthiness requirements.
Under the Civil Aviation Act 1988, any breaches of the ADs can result in significant consequences. Failure to comply with an AD can lead to severe civil penalties, including fines up to the maximum statutory limits, or criminal penalties if the breach is deemed to have endangered safety. For example, non-compliance with an AD can result in fines of up to $1.1 million for a corporation and $220,000 for an individual, as well as potential imprisonment for directors or other responsible persons. Furthermore, the cancellation of an AD, as in the case of AD/BEECH 56/28, does not require public consultation as it is deemed to reduce the regulatory burden. The Office of Best Practice Regulation has also determined that ADs do not require a Regulatory Impact Statement, streamlining the process further.
The Act and Regulations provide a clear framework for the issuance, assessment, and enforcement of ADs to ensure airworthiness. CASA’s role is pivotal in maintaining these standards, ensuring that all aircraft meet the necessary safety requirements. The cancellation of AD/BEECH 56/28 demonstrates CASA’s commitment to reviewing and updating regulations to align with current safety standards and reduce unnecessary regulatory burdens.
