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 issued AD 2006-0236R1 affecting Airbus A320 series aircraft. The EASA is the State of Design for Airbus A320 aircraft. CASA has amended the equivalent Australian AD to AD/A320/180 Amendment 2. The amended AD will become effective on 30 April 2007. This AD cancels and replaces the previous issue.
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, enacted by the Australian Parliament, establishes a framework for the regulation of civil aviation in Australia, with a primary focus on ensuring the safety of air navigation. As part of its regulatory powers, the Civil Aviation Safety Regulations 1998 allow the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) to mandate requirements for maintaining the airworthiness of aircraft and aeronautical products. These ADs are legislative instruments, subject to disallowance, and are issued in response to international obligations under the Convention on International Civil Aviation. When the European Aviation Safety Agency (EASA) issues an AD for a type of aircraft registered in Australia, such as the Airbus A320, CASA is required to assess the information and, if necessary, issue an equivalent AD to ensure compliance with international standards. The recent amendment to AD/A320/180 Amendment 2, effective from 30 April 2007, is an example of this process, aligning Australian regulations with those of the EASA, the State of Design for the Airbus A320 aircraft.
Scope and Application
The Civil Aviation Act 1988, supported by the Civil Aviation Safety Regulations 1998, provides the framework for ensuring the safety of air navigation in Australia. Under this legislative structure, the Civil Aviation Safety Authority (CASA) has the authority to issue airworthiness directives (ADs) for specific kinds of aircraft or aeronautical products. These ADs are legislative instruments that mandate requirements for maintaining the airworthiness of aircraft registered in Australia, ensuring compliance with international standards as outlined in Annex 8 to the Convention on International Civil Aviation. The State of Design, such as the European Union Aviation Safety Agency (EASA) for Airbus A320 aircraft, holds the primary responsibility for continuing airworthiness, while the State of Registry, in this case CASA, ensures these requirements are implemented and enforced within Australia. The issuance of ADs, such as the recent amendment to AD/A320/180 Amendment 2, reflects Australia's commitment to international civil aviation standards and is issued without public consultation as it pertains to international obligations and pre-existing ADs from the State of Design.
Key Provisions
The Civil Aviation Act 1988 provides the legal framework for civil aviation in Australia, and section 98 specifically empowers the Governor-General to make regulations in the interests of air navigation safety. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 then grants the Civil Aviation Safety Authority (CASA) the authority to issue airworthiness directives (ADs) for specified types of aircraft or aeronautical products. These ADs are legislative instruments, as outlined in subregulation 39.001(5) and further clarified by section 6 of the Legislative Instruments Act 2003. Such directives are crucial tools in ensuring the ongoing safety and airworthiness of aircraft, reflecting obligations under Annex 8 to the Convention on International Civil Aviation.
In compliance with international obligations, the State of Design holds the primary responsibility for the continuing airworthiness of an aircraft type, and must provide necessary information to ensure that the aircraft remains airworthy. The State of Registry, where the aircraft is registered, must develop or adopt requirements to ensure the continuing airworthiness of aircraft within its jurisdiction. CASA, as Australia’s national airworthiness authority, plays a pivotal role in this process by assessing information from the State of Design and, when necessary, issuing Australian ADs to mandate the requirements for aircraft registered in Australia. This ensures that all aircraft meet the necessary safety standards, harmonising with international practices.
The obligations imposed by the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 on CASA and other entities include the assessment and implementation of ADs issued by the State of Design. CASA must ensure that these directives are effectively communicated and enforced within Australia. The State of Registry is required to implement the ADs to maintain the airworthiness of individual aircraft. Failure to comply with these directives could result in serious safety risks, thus mandating strict adherence to the ADs by all relevant parties.
Breaches of the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 can lead to significant consequences. While the specific offences and penalties are not detailed in the provided text, violations of airworthiness directives can result in both civil and criminal penalties. Civil penalties may include fines, while criminal penalties could encompass imprisonment, reflecting the critical importance of compliance with these safety regulations. The severity of these consequences underscores the necessity for strict adherence to airworthiness directives to ensure the safety of air navigation.
