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 US FAA has issued AD 2006-12-23 affecting Boeing B737 model aircraft. The USA is the State of Design for this type. CASA has assessed this AD and has issued Australian AD/B737/175, Amendment 1, which will become effective on 3 August 2006. 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, Airframes 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 Parliament of Australia, aims to ensure the safety and efficiency of civil aviation within Australia and its territories. The Act empowers the Governor-General to make regulations that serve the interests of air navigation safety, including the issuance of airworthiness directives (ADs). Under regulation 39.001 of the Civil Aviation Safety Regulations 1998, the Civil Aviation Safety Authority (CASA) can issue ADs for specific types of aircraft or aeronautical products to ensure their continuing airworthiness. This legislative framework addresses the need to maintain high safety standards in aviation, aligning with international obligations under the Convention on International Civil Aviation. The ADs are critical tools for CASA to mandate safety requirements, especially when responding to directives from the State of Design, as exemplified by the issuance of Australian AD/B737/175, Amendment 1, in response to a US Federal Aviation Administration directive. This process underscores CASA’s role in upholding both domestic and international aviation safety standards.
Scope and Application
The Civil Aviation (Airworthiness) Regulations 1998, specifically under regulation 39.001, empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for certain types of aircraft or aeronautical products, as a legislative instrument under the Acts Interpretation Act 1901. This authority is exercised in accordance with section 98 of the Civil Aviation Act 1988 to ensure the safety of air navigation. The ADs serve as a crucial mechanism for maintaining the continuing airworthiness of aircraft, a responsibility shared by both the State of Design and the State of Registry. The State of Design is obligated to issue ADs, while the State of Registry, in this case CASA for Australia, must assess these ADs and issue corresponding directives as necessary to comply with international standards, such as those outlined in Annex 8 to the Convention on International Civil Aviation. The ADs are issued without public consultation due to their international obligations and direct response to directives from the relevant State of Design. The AD issued for Boeing B737 model aircraft, for example, cancels and replaces previous directives, reflecting CASA’s commitment to safety and regulatory compliance.
Key Provisions
The key provisions of the Civil Aviation Act 1988, as they relate to the issuance of airworthiness directives (ADs), are found in section 98, which allows the Governor-General to make regulations for the safety of air navigation, and regulation 39.001 of the Civil Aviation Safety Regulations 1998, which specifically enables the Civil Aviation Safety Authority (CASA) to issue ADs for kinds of aircraft or aeronautical products. Under subregulation 39.001(5), ADs are considered disallowable instruments as per section 46A of the Acts Interpretation Act 1901, and thus legislative instruments according to section 6 of the Legislative Instruments Act 2003. This legislative framework underscores the importance of maintaining the safety standards of aircraft and aeronautical products, and the role of CASA in implementing these regulations.
The obligations and requirements imposed by the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 on parties and entities are primarily centred around the maintenance of airworthiness. The State of Design, which is the country responsible for the original design of the aircraft, has the responsibility to provide necessary information to ensure the continuing airworthiness of the aircraft type. The State of Registry, in this case Australia, must develop or adopt requirements to ensure the continuing airworthiness of aircraft within its jurisdiction. CASA, as Australia's national airworthiness authority, is tasked with assessing information from the State of Design and, if appropriate, issuing an Australian AD to mandate the requirements of the State of Design. This obligation ensures that all aircraft registered in Australia comply with internationally recognised safety standards.
Breaching the obligations or requirements set out in the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 can result in various consequences, both civil and criminal. The maximum penalties for breaches can vary depending on the severity of the offence, but they are designed to ensure compliance with safety regulations and to protect the public from the risks associated with non-compliance. The Act does not explicitly detail the penalties for breaches, but it is understood that serious breaches could lead to significant fines or even imprisonment. The issuing of ADs and their subsequent enforcement is a critical aspect of maintaining the safety and airworthiness of aircraft, and non-compliance can have serious implications for all parties involved.
