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 2008-01-03 affecting Learjet 45 model aircraft. The USA is the State of Design for this type. CASA has assessed this AD and has issued Australian AD/LJ45/12, which will become effective on 13 March 2008.
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 Best Practice Regulation has determined that ADs do not require a Regulatory Impact Statement.
The AD has been made by the Manager, Airframes in the Airworthiness Engineering Branch, on behalf of CASA, in accordance with subsection 84A (2) of the Act.
Overview
The Civil Aviation Act 1988 was enacted to provide a comprehensive legal framework for the regulation of civil aviation in Australia, ensuring safety and efficiency in air navigation. The Act empowers the Governor-General to make regulations to further the objectives of the Act, with a primary focus on the safety of air navigation. In line with this, the Civil Aviation Safety Regulations 1998 allow the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products to ensure compliance with safety standards. The ADs are considered legislative instruments under the Acts Interpretation Act 1901 and the Legislative Instruments Act 2003. These directives are essential for maintaining the continuing airworthiness of aircraft as mandated by Annex 8 to the Convention on International Civil Aviation. The responsibility of the State of Registry, such as CASA in Australia, is to ensure that aircraft are maintained in a safe condition, and this includes issuing ADs in response to those issued by the State of Design, such as the US Federal Aviation Administration (FAA) for certain aircraft types. This legislative and regulatory framework underscores Australia’s commitment to international civil aviation standards and safety.
Scope and Application
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 provide the legislative framework for the issuance of airworthiness directives (ADs) in Australia, which are critical for ensuring the safety of aircraft types on the Australian Register. Pursuant to section 98 of the Civil Aviation Act 1988, the Governor-General is empowered to make regulations for the purposes of the Act, and regulation 39.001 of the Civil Aviation Safety Regulations 1998 specifically allows the Civil Aviation Safety Authority (CASA) to issue ADs for certain kinds of aircraft or aeronautical products. These directives are legislative instruments that must comply with the Legislative Instruments Act 2003. Under international obligations, notably Annex 8 to the Convention on International Civil Aviation, the State of Design holds primary responsibility for the continuing airworthiness of an aircraft type and must provide necessary information to States of Registry, including Australia. CASA, as Australia’s national airworthiness authority, is tasked with assessing ADs issued by States of Design and issuing corresponding Australian ADs if deemed necessary. The issuance of ADs such as the one affecting Learjet 45 model aircraft, originally issued by the US Federal Aviation Administration (FAA) and adopted by CASA as AD/LJ45/12, is a direct response to international commitments and does not require public consultation or a Regulatory Impact Statement. This process underscores the jurisdictional reach and responsibilities of CASA in maintaining airworthiness standards.
Key Provisions
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 together provide the legislative framework under which airworthiness directives (ADs) are issued and enforced in Australia. Under section 98 of the Act, the Governor-General has the authority to make regulations in the interests of air navigation safety, and regulation 39.001 specifically empowers the Civil Aviation Safety Authority (CASA) to issue ADs for aircraft or aeronautical products. Furthermore, subregulation 39.001(5) identifies ADs as disallowable instruments, and therefore legislative instruments under section 6 of the Legislative Instruments Act 2003.
The obligations imposed by the Act and Regulations on the State of Design, which is the country where the aircraft type is designed, and the State of Registry, which is the country where the aircraft is registered, are critical. The State of Design has the overarching responsibility for ensuring the continuing airworthiness of an aircraft type, as stipulated in Annex 8 to the Convention on International Civil Aviation. This includes providing necessary information to States of Registry. Conversely, the State of Registry must develop or adopt requirements to ensure the continuing airworthiness of aircraft registered within its jurisdiction. When a State of Design issues an AD, the State of Registry, in this case CASA, must assess this information and, if necessary, issue a corresponding AD to enforce the requirements within its jurisdiction.
Failure to comply with an AD can lead to significant consequences. While the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 do not explicitly outline specific offences, penalties, or consequences for breaching an AD, non-compliance can result in severe safety risks and potential legal actions. The authority to enforce compliance and impose penalties typically arises from other provisions within the Act and related regulations, such as those pertaining to the operation of aircraft in a manner that endangers safety. Penalties can range from fines to imprisonment, depending on the severity of the breach and the discretion of the court. The issuance of ADs is governed under these regulations to ensure that all necessary measures are taken to maintain the highest standards of aviation safety.
