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 2006-0140R3 affecting aircraft fitted with certain Zonal Drying Systems manufactured by Lufthansa Technik AG, SR Technics, Jet Aviation Basel AG, and CTT Systems AB. Various national aviation authorities operating under the EASA are the State of Design for these systems. As a result CASA has amended the equivalent Australian AD to AD/AIRCON/14 Amendment 3. The amended AD will become effective on 25 May 2009. 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, Systems and New Technologies in the Airworthiness Engineering Group, on behalf of CASA, in accordance with subsection 84A (2) of the Act.
Overview
The Civil Aviation Act 1988 was enacted to provide a legislative framework for ensuring the safety of air navigation in Australia, and it empowers the Governor-General to make regulations for this purpose. Complementing this Act, the Civil Aviation Safety Regulations 1998 allow the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) to maintain the continuing airworthiness of aircraft and aeronautical products. These ADs, being legislative instruments, are subject to disallowance and must comply with the Legislative Instruments Act 2003. In line with international obligations under Annex 8 to the Convention on International Civil Aviation, the State of Design has the responsibility for the continuing airworthiness of an aircraft type, while the State of Registry ensures the airworthiness of individual aircraft. CASA, as Australia's national airworthiness authority, must assess information from the State of Design and, if necessary, issue corresponding ADs. The AD in question, issued by CASA in response to an AD from the European Aviation Safety Agency (EASA) concerning certain Zonal Drying Systems, mandates compliance with international safety standards, thus reflecting Australia's commitment to global aviation safety protocols.
Scope and Application
The Civil Aviation Act 1988 applies to all entities and persons involved in civil aviation within Australia, as well as to aircraft and aeronautical products registered in Australia, thereby establishing a regulatory framework for the safety of air navigation. The Civil Aviation Safety Regulations 1998 further detail the application of this Act, particularly in relation to the issuance of airworthiness directives (ADs), which are regulatory instruments used to mandate safety measures for specific types of aircraft or aeronautical products. These ADs are issued by the Civil Aviation Safety Authority (CASA) under the authority granted by the Act and are aimed at ensuring the continuing airworthiness of aircraft registered in Australia. The ADs are subject to disallowance and are considered legislative instruments under the Acts Interpretation Act 1901 and the Legislative Instruments Act 2003. As Australia is a signatory to the Convention on International Civil Aviation, it has obligations to align its airworthiness directives with those issued by other contracting states, ensuring a consistent international approach to aviation safety.
Key Provisions
The Civil Aviation (Safety) Regulations 1998, specifically under regulation 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 legislative instruments that ensure the safety of air navigation, as outlined in section 98 of the Civil Aviation Act 1988. They are critical tools for maintaining the continuing airworthiness of aircraft as stipulated under Annex 8 to the Convention on International Civil Aviation. When an AD is issued by a State of Design, CASA, as Australia's national airworthiness authority, must assess the information and, if necessary, issue a corresponding Australian AD to enforce the requirements of the State of Design.
The obligations imposed by the Civil Aviation (Safety) Regulations 1998 on CASA and the State of Registry are significant. The State of Design has the overarching responsibility for the continuing airworthiness of an aircraft type, while the State of Registry must ensure that the aircraft on their register meet all necessary airworthiness standards. This includes developing or adopting requirements to ensure the continuing airworthiness of aircraft and responding appropriately to ADs issued by the State of Design. For example, CASA must assess the information in an AD issued by the European Aviation Safety Agency (EASA) and issue an equivalent Australian AD to ensure compliance with international standards.
Failure to comply with the provisions of an AD can result in severe consequences. Under the Civil Aviation Act 1988, non-compliance can lead to both civil and criminal penalties. The maximum penalties for contravening ADs are substantial and can include fines and imprisonment. The precise penalties depend on the nature and severity of the breach, but they underscore the importance of adhering to these regulations to maintain the safety of air navigation.
In summary, the Civil Aviation (Safety) Regulations 1998 provide CASA with the authority to issue airworthiness directives, which are essential for maintaining the safety and airworthiness of aircraft. The State of Registry has the obligation to ensure compliance with these directives, and failure to do so can result in severe civil and criminal penalties. The issuance of ADs such as AD/AIRCON/14 Amendment 3 is a direct response to international safety standards and ensures that Australian aircraft meet the necessary safety requirements.
