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 2006-19-14 affecting Honeywell Communications Units and associated Mode S Transponders. The United States is the State of Design for these equipments. CASA has assessed this AD and has issued Australian AD/RAD/88, which will become effective on 8 August 2007.
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 Acting 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 Commonwealth Parliament, addresses the need for comprehensive regulation in the interests of aviation safety and air navigation. The Act empowers the Governor-General to establish regulations that serve these objectives, with specific provisions enabling the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for particular types of aircraft or aeronautical products. This legislative framework is critical for ensuring that aircraft remain airworthy and safe, in line with international standards set forth by the International Civil Aviation Organization (ICAO). The Civil Aviation Safety Regulations 1998 further operationalise these provisions, allowing CASA to mandate necessary safety measures through ADs, which are recognised as legislative instruments under the Acts Interpretation Act 1901 and the Legislative Instruments Act 2003. These directives are instrumental in maintaining the safety and airworthiness of aircraft, particularly when issued in response to international safety concerns as highlighted by the United States Federal Aviation Administration (FAA).
Scope and Application
The Civil Aviation Act 1988, together with the Civil Aviation Safety Regulations 1998, governs the issuance of airworthiness directives (ADs) as a means to ensure the safety of air navigation. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 empowers the Civil Aviation Safety Authority (CASA) to issue ADs for specific kinds of aircraft or aeronautical products. These directives, as legislative instruments, are formulated in compliance with Annex 8 to the Convention on International Civil Aviation, which assigns the State of Design the overarching responsibility for the continuing airworthiness of aircraft types and mandates the provision of necessary information to the States of Registry. In Australia, CASA, acting as the national airworthiness authority, must evaluate any AD issued by a State of Design and, if necessary, issue corresponding Australian ADs to enforce the requisite safety measures. This regulatory framework ensures that Australian aircraft meet international safety standards, with the AD process being a direct response to international obligations and assessments rather than public consultation, and without the need for a Regulatory Impact Statement.
Key Provisions
The Civil Aviation Act 1988, as amended by the Civil Aviation Safety Regulations 1998, provides a framework for ensuring the safety of air navigation in Australia. Under section 98 of the Civil Aviation Act 1988, the Governor-General is empowered to make regulations, including issuing airworthiness directives (ADs), to safeguard the safety of air navigation. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 specifically allows the Civil Aviation Safety Authority (CASA) to issue ADs for certain types of aircraft or aeronautical products. These directives are essential tools for maintaining the airworthiness of aircraft and ensuring safety standards are consistently met.
The obligations imposed by these regulations on the parties involved are substantial. The State of Design, which is the country where the aircraft or aeronautical product was designed, has the primary responsibility for the continuing airworthiness of the type of aircraft. This includes providing necessary information to ensure that the aircraft remain airworthy. On the other hand, the State of Registry, which is the country where the aircraft is registered, is responsible for ensuring the continuing airworthiness of individual aircraft by developing or adopting appropriate requirements. In Australia, CASA acts as the national airworthiness authority and must assess information from the State of Design and, if necessary, issue an Australian AD to mandate the requirements of the State of Design.
Failure to comply with airworthiness directives can result in serious legal consequences. While the Civil Aviation Safety Regulations 1998 do not explicitly outline specific offences or penalties for non-compliance with ADs, breaches of these regulations could potentially lead to actions under broader aviation safety laws. For instance, non-compliance with airworthiness requirements could be prosecuted under the Civil Aviation Act 1988, leading to criminal penalties. The severity of these penalties can vary but may include substantial fines and imprisonment. Additionally, civil penalties might apply, and aircraft found to be non-airworthy could be grounded, preventing their operation until compliance is achieved.
