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 55/25, affecting Beech 55 model 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, enacted by the Commonwealth Parliament, was introduced to ensure the safety of air navigation and to regulate civil aviation in Australia. Under this Act, the Civil Aviation Safety Regulations 1998 were established, which allow the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products to maintain safety standards. The objective is to ensure the continuing airworthiness of aircraft, aligning with international standards set by the International Civil Aviation Organization (ICAO). CASA, as Australia’s national airworthiness authority, assesses information provided by the State of Design and issues corresponding ADs, which are legislative instruments. For instance, CASA issued and subsequently decided to cancel AD/BEECH 55/25 for Beech 55 model aircraft, effective from 17 January 2008, as the original safety concerns have been addressed by another directive. This cancellation reflects a reduction in regulatory burden, and no public consultation was deemed necessary as per the Office of Best Practice Regulation.
Scope and Application
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 provide the framework for the issuance of airworthiness directives (ADs) in Australia, ensuring the safety of air navigation and the continuing airworthiness of aircraft. Under section 98 of the Civil Aviation Act 1988, the Governor-General may make regulations to further the objectives of the Act, with the Civil Aviation Safety Regulations 1998 specifically allowing the Civil Aviation Safety Authority (CASA) to issue ADs for certain kinds of aircraft or aeronautical products, as outlined in regulation 39.001. These ADs are legislative instruments under the Acts Interpretation Act 1901 and the Legislative Instruments Act 2003. The ADs serve to implement international standards set by Annex 8 to the Convention on International Civil Aviation, which assigns responsibility for continuing airworthiness to the State of Design and the State of Registry. CASA, as Australia's national airworthiness authority, must review and, if necessary, issue Australian ADs to enforce the requirements of foreign ADs for aircraft on the Australian Register. For example, CASA issued and subsequently cancelled AD/BEECH 55/25 for Beech 55 model aircraft, which was rendered redundant by AD/GENERAL/74 Amendment 1, reflecting the evolving safety measures without necessitating public consultation or a Regulatory Impact Statement due to the reduced regulatory burden.
Key Provisions
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 provide a framework for the regulation of civil aviation safety in Australia. Under section 98 of the Civil Aviation Act 1988, the Governor-General has the authority to make regulations that ensure the safety of air navigation. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 empowers the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for certain types of aircraft or aeronautical products. An AD, as per subregulation 39.001(5), is a disallowable instrument under section 46A of the Acts Interpretation Act 1901 and is thus considered a legislative instrument under section 6 of the Legislative Instruments Act 2003. These ADs are critical for maintaining the continuing airworthiness of aircraft, as mandated by Annex 8 to the Convention on International Civil Aviation, which assigns the State of Design the responsibility for providing necessary information to ensure airworthiness.
Obligations under these regulations are extensive. The State of Design must provide any information necessary to ensure the continuing airworthiness of an aircraft type, while the State of Registry must develop or adopt requirements to ensure the airworthiness of individual aircraft. In Australia, CASA, as the national airworthiness authority, has the responsibility to assess information from the State of Design and, if appropriate, issue an Australian AD to enforce the required safety measures. This ensures that Australian aircraft meet international safety standards.
Breaching the requirements set out in these ADs can have serious consequences. Under the Civil Aviation Act 1988, non-compliance with ADs can result in civil penalties, including fines. The exact penalty may vary depending on the nature and severity of the breach. In addition to civil penalties, CASA may take enforcement actions such as grounding the aircraft until compliance is achieved, which can have significant operational and financial implications for the aircraft operator. Furthermore, continued non-compliance could lead to criminal charges, where the offender may face imprisonment, reflecting the high importance placed on aviation safety.
