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.
The EASA has issued AD 2006-0120-E affecting Agusta A109S aircraft. EASA is the State of Design for this type. CASA has assessed this AD and has issued Australian AD/A109/53, which will become effective on 18 May 2006.
As this AD is issued because of Australia’s obligations under Convention on International Civil Aviation, and because it is issued in response to an AD raised by the relevant State of Design, no consultation of the Australian public has taken place on this AD. The Office of Regulatory Review has determined that ADs do not require a Regulatory Impact Statement.
The AD has been made by the Manager, New Technologies and Systems, in the Manufacturing, Certification and New Technologies Office, 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, focusing on ensuring the safety and efficiency of air navigation. The Civil Aviation Safety Regulations 1998 further support the Act by detailing specific regulations governing the safety of aircraft and aeronautical products. One of the key mechanisms established by these regulations is the issuance of airworthiness directives (ADs), which are legislative instruments aimed at maintaining the airworthiness of aircraft. Under section 98 of the Civil Aviation Act 1988, the Governor-General has the authority to make such regulations, while regulation 39.001 of the Civil Aviation Safety Regulations 1998 empowers the Civil Aviation Safety Authority (CASA) to issue ADs. The objective of this regulatory framework is to ensure compliance with international standards, particularly those outlined in Annex 8 of the Convention on International Civil Aviation, which assigns the State of Design responsibility for the continuing airworthiness of aircraft types.
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, thereby ensuring compliance with safety standards. These directives are legislative instruments, as defined by the Legislative Instruments Act 2003, and they reflect Australia's obligations under the Convention on International Civil Aviation. The ADs mandate requirements for the continuing airworthiness of aircraft, particularly when issued by the State of Design, such as the European Aviation Safety Agency (EASA) in the case of the Agusta A109S aircraft. CASA assesses these international directives and, if deemed appropriate, issues corresponding Australian ADs, such as AD/A109/53 for the Agusta A109S. This process is integral to maintaining safety standards across the aviation industry in Australia, ensuring that aircraft registered within the country meet internationally recognised safety requirements. Given that these directives are issued in response to international obligations and assessments, they do not require public consultation or a Regulatory Impact Statement.
Key Provisions
The Civil Aviation Safety Regulations 1998, particularly regulation 39.001, allow the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) concerning specific types of aircraft or aeronautical products. These ADs are made under the authority granted by section 98 of the Civil Aviation Act 1988, ensuring that such regulations are in the interests of air navigation safety. An AD, as described in subregulation 39.001(5), is a disallowable instrument under section 46A of the Acts Interpretation Act 1901 and is considered a legislative instrument pursuant to section 6 of the Legislative Instruments Act 2003. These directives serve as a mechanism for states to communicate necessary actions to maintain the continuing airworthiness of aircraft, aligning with international standards set by Annex 8 to the Convention on International Civil Aviation.
Under these regulations, the State of Design, such as the European Aviation Safety Agency (EASA) for certain aircraft types, holds the responsibility for ensuring the continuing airworthiness of the aircraft type. They are obligated to provide necessary information to the State of Registry, which in the case of Australian-registered aircraft, is CASA. The State of Registry, CASA in this instance, must develop or adopt requirements that ensure the aircraft's ongoing airworthiness. When EASA issues an AD, CASA is required to evaluate this information and, if deemed necessary, issue an Australian AD to enforce the requirements specified by the State of Design.
The obligations imposed on CASA and other entities governed by these regulations include assessing the necessity of issuing an Australian AD in response to an AD from the State of Design. This involves a thorough evaluation to ensure that the requirements align with Australian safety standards and are applicable to aircraft registered in Australia. Once an AD is issued, entities such as aircraft operators, owners, and maintenance providers must comply with the mandated requirements to ensure the continuing airworthiness of the affected aircraft. Failure to comply with these directives can lead to serious safety risks and may result in enforcement actions by CASA.
Breaches of airworthiness directives can result in significant consequences. Under the Civil Aviation Act 1988, non-compliance with an AD can be considered an offence, potentially leading to civil or criminal penalties. The specific penalties for such breaches are not detailed in the provided text, but generally, they can include fines and, in severe cases, imprisonment. The enforcement of these regulations is critical to maintaining the high safety standards expected in civil aviation, and CASA has the authority to take necessary actions to ensure compliance with the issued ADs.
