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 23/25, affecting Beech 23 model aircraft in 1974. 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 establish and maintain a regulatory framework that ensures the safety and efficiency of civil aviation in Australia. The 1988 Act provides the legislative foundation for the regulation of air navigation safety, aircraft operations, and airworthiness, among other aspects of civil aviation. Under the authority granted by this Act, the Civil Aviation Safety Regulations 1998 were established to provide further detail on specific safety requirements. One such requirement is the issuance of airworthiness directives (ADs), which are regulatory instruments used to mandate safety measures concerning aircraft types or aeronautical products. The Civil Aviation (Administrative and Support) Amendment Regulations 2008 (F2008L00882) relate to the cancellation of a specific AD (AD/BEECH 23/25) concerning the Beech 23 model aircraft from 1974. This cancellation was decided by the Civil Aviation Safety Authority (CASA) based on the assessment that the original unsafe condition no longer exists, thereby reducing the regulatory burden without necessitating a replacement AD. This regulatory action was taken under the authority of the Civil Aviation Act 1988 and implemented by CASA, reflecting the ongoing commitment to safety and efficiency within the Australian civil aviation sector.
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. These directives are essential tools for maintaining the safety of air navigation and are applicable to the continuing airworthiness of aircraft within Australia. The ADs are formulated in accordance with Annex 8 to the Convention on International Civil Aviation, which stipulates that the State of Design has the primary responsibility for ensuring the continuing airworthiness of aircraft types. CASA, as Australia's national airworthiness authority, must assess the information provided by the State of Design and, if necessary, issue corresponding Australian ADs. The legislative framework allows for ADs to be issued by the Manager, Airframes in the Airworthiness Engineering Branch on behalf of CASA, under the authority granted by the Civil Aviation Act 1988. Notably, the cancellation of an AD, such as AD/BEECH 23/25 affecting Beech 23 model aircraft in 1974, can be implemented without public consultation if it reduces regulatory burden, as determined by the Office of Best Practice Regulation. The AD cancellation process is designed to ensure that the regulatory requirements remain aligned with the safety standards necessary for Australian airspace.
Key Provisions
The Civil Aviation (Airworthiness) Regulations 1998, specifically regulation 39.001, empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for certain kinds of aircraft or aeronautical products, as outlined in section 98 of the Civil Aviation Act 1988. This authority stems from the need to ensure the safety of air navigation and is exercised in line with international standards, particularly those set out in Annex 8 to the Convention on International Civil Aviation. According to these regulations, an AD is considered a legislative instrument under section 6 of the Legislative Instruments Act 2003 and is a disallowable instrument under section 46A of the Acts Interpretation Act 1901.
The obligations imposed by these regulations are significant for both CASA and the State of Registry of individual aircraft. The State of Design must provide necessary information to ensure the continuing airworthiness of aircraft types, while the State of Registry must develop or adopt requirements to ensure the ongoing airworthiness of specific aircraft registered within its jurisdiction. CASA, as Australia’s national airworthiness authority, must assess any ADs issued by States of Design and determine if an Australian AD is necessary to mandate these requirements for aircraft registered in Australia. This ensures that all aircraft operating within Australia meet the required safety standards.
The cancellation of an airworthiness directive, such as AD/BEECH 23/25 affecting Beech 23 model aircraft from 1974, is a crucial process overseen by CASA. This particular AD has been cancelled effective 10 April 2008, as the unsafe condition it addressed no longer exists. This action is taken without public consultation because it results in a reduction of the regulatory burden, as confirmed by the Office of Best Practice Regulation, which determined that such ADs do not require a Regulatory Impact Statement. The cancellation was made by the Manager, Airframes in the Airworthiness Engineering Branch, on behalf of CASA, in accordance with subsection 84A(2) of the Act.
Breaches of the requirements set out in these regulations can lead to significant consequences. The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 provide for various penalties for non-compliance. Offences may result in civil or criminal penalties, including fines and imprisonment, depending on the severity of the breach. For example, failure to comply with an airworthiness directive can result in substantial fines and potential imprisonment, reflecting the critical nature of these regulations in maintaining aviation safety standards.
