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 2006-14-07 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/B737/292, which will become effective on 31 August 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, 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 was enacted to provide a legislative framework that ensures the safety, efficiency, and orderly growth of civil aviation in Australia. This Act, created by the Commonwealth Parliament, addresses the need for comprehensive regulation of civil aviation, including the establishment of safety standards and oversight mechanisms. Its policy objective is to enhance the safety and efficiency of civil aviation through stringent regulatory measures and to ensure that the Australian aviation industry adheres to international standards. Under this Act, the Civil Aviation Safety Regulations 1998 were also introduced to provide detailed rules and standards for ensuring airworthiness. These regulations empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs), which are legislative instruments that mandate corrective actions to maintain the airworthiness of aircraft. These directives are crucial for addressing specific safety issues and ensuring compliance with international obligations under the Convention on International Civil Aviation.
Scope and Application
The Civil Aviation Safety Regulations 1998, under regulation 39.001, empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific kinds of aircraft or aeronautical products. These directives are legislative instruments, subject to disallowance under section 46A of the Acts Interpretation Act 1901 and regulated by the Legislative Instruments Act 2003. This regulatory framework applies to all aircraft registered in Australia, encompassing both domestic and international entities, and extends to the entire Australian airspace. ADs are issued in response to safety concerns identified by the aircraft's State of Design and must be assessed and, if necessary, adopted by CASA to ensure compliance with international standards under the Convention on International Civil Aviation. Exemptions or exclusions from ADs are not explicitly detailed in the provided text, but it is implied that non-compliance could lead to enforcement actions under the Civil Aviation Act 1988. The application of these regulations can be further detailed or modified through subordinate instruments, which adhere to the overarching legislative intent to maintain the safety of air navigation.
Key Provisions
The Civil Aviation Safety Regulations 1998, under regulation 39.001, provide that the Civil Aviation Safety Authority (CASA) may issue airworthiness directives (ADs) for particular kinds of aircraft or aeronautical products. This regulatory power is derived from section 98 of the Civil Aviation Act 1988, which empowers the Governor-General to make regulations for the Act’s purposes, particularly in the interest of air navigation safety. Furthermore, subregulation 39.001(5) clarifies that an AD is a disallowable instrument under section 46A of the Acts Interpretation Act 1901, thereby categorising it as a legislative instrument pursuant to section 6 of the Legislative Instruments Act 2003.
The obligations placed on parties governed by these provisions are significant. The State of Design, which in this case is the United States of America for Boeing B737 model aircraft, holds the primary responsibility for the continuing airworthiness of the aircraft type. This responsibility includes providing necessary information to ensure the aircraft’s continued safe operation. In parallel, the State of Registry, which for Australian-registered aircraft is CASA, must develop or adopt requirements to ensure the aircraft’s continuing airworthiness. When an AD is issued by the State of Design, CASA is obligated to assess the directive and, if appropriate, issue an Australian AD to enforce the requirements stipulated by the State of Design.
Failing to comply with the ADs can result in serious legal and safety consequences. The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 do not explicitly state the penalties for non-compliance with ADs. However, non-compliance can potentially lead to civil or criminal penalties, depending on the severity of the breach. Given the critical nature of airworthiness directives, breaches may attract significant sanctions, including fines and potential imprisonment, reflecting the high stakes involved in aviation safety. The specific penalties would be determined based on the nature and extent of the violation, as well as the relevant legislative framework governing aviation safety and enforcement.
