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 United States FAA has issued AD 2006-17-07 affecting Pratt and Whitney Aircraft JT8D series engines. The United States is the State of Design for these engines. CASA has assessed this AD and has issued Australian AD/JT8D/42, which will become effective on 26 October 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 ensure the safety and efficiency of civil aviation in Australia, providing a framework for the regulation of civil aviation activities. The Act empowers the Governor-General to make regulations in the interests of air navigation safety. One such regulation, under section 39.001 of the Civil Aviation Safety Regulations 1998, allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. These directives are legislative instruments and are crucial for ensuring the continuing airworthiness of aircraft types, in alignment with international standards set by the International Civil Aviation Organization (ICAO). This legislative framework enables CASA to mandate compliance with international ADs issued by States of Design, ensuring that Australian aircraft meet global safety standards. CASA's role as the national airworthiness authority requires it to assess and, where necessary, issue ADs to maintain the safety and airworthiness of aircraft registered in Australia.
Scope and Application
The Civil Aviation Safety Regulations 1998, under the Civil Aviation Act 1988, empowers the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) concerning specific types of aircraft or aeronautical products. This regulatory framework applies to entities such as aircraft manufacturers, airlines, and aviation maintenance organisations that operate within Australia, ensuring adherence to safety standards for air navigation. The scope of these directives is dictated by international obligations under the Convention on International Civil Aviation, specifically Annex 8, which mandates that the State of Design (in this case, the United States for Pratt and Whitney Aircraft JT8D series engines) must provide necessary information for ensuring continuing airworthiness. CASA, as Australia’s national airworthiness authority, is tasked with assessing these international directives and issuing corresponding Australian ADs when necessary. This process ensures that Australian-registered aircraft meet required safety standards. The issuance of such directives does not require public consultation or a Regulatory Impact Statement, reflecting the urgency and importance of maintaining airworthiness standards.
Key Provisions
The Civil Aviation Act 1988, as augmented by the Civil Aviation Safety Regulations 1998, allows for the issuance of airworthiness directives (ADs) by the Civil Aviation Safety Authority (CASA). Specifically, section 98 of the Act provides the Governor-General with the authority to create regulations in the interests of air navigation safety, while regulation 39.001 empowers CASA to issue ADs for certain aircraft or aeronautical products. This is further clarified in subregulation 39.001(5), which stipulates that an AD is a disallowable instrument under section 46A of the Acts Interpretation Act 1901 and thus a legislative instrument as per section 6 of the Legislative Instruments Act 2003.
These airworthiness directives are mandated by Annex 8 to the Convention on International Civil Aviation, which designates the State of Design with overall responsibility for an aircraft type's continuing airworthiness. The State of Design must provide necessary information to ensure the aircraft's airworthiness, typically communicated through ADs, which are adopted by most International Civil Aviation Organization (ICAO) Contracting States. The State of Registry, which in Australia is CASA, must then develop or adopt requirements to ensure the continuing airworthiness of the aircraft registered within its jurisdiction. This process is exemplified by the issuance of Australian AD/JT8D/42, which responds to the United States Federal Aviation Administration's AD 2006-17-07 concerning Pratt and Whitney Aircraft JT8D series engines.
The obligations placed on the parties governed by these provisions include a duty for the State of Design to issue ADs to ensure continuing airworthiness, and a corresponding obligation for the State of Registry, in this case CASA, to assess these ADs and issue Australian ADs as necessary. This ensures that all aircraft registered in Australia meet the continuing airworthiness standards set by the State of Design. The lack of public consultation on this specific AD is justified by its basis in international obligations under the Convention on International Civil Aviation and the determination by the Office of Regulatory Review that such ADs do not require a Regulatory Impact Statement.
Failure to comply with the requirements set out in an AD can lead to significant consequences. Under the Civil Aviation Act 1988, non-compliance can result in civil penalties, including fines, as well as potential criminal charges. The severity of these penalties can vary based on the nature and extent of the breach, but they underscore the importance of adhering to airworthiness directives to ensure the safety of air navigation.
