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 German LBA has issued AD 97-136 affecting AvCraft Aerospace GmbH Dornier 328-100 model aircraft. Germany is the State of Design for these types. CASA has assessed this AD and has issued Australian AD/DO 328/20, which will become effective on 19 January 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 regulate civil aviation and to establish the Civil Aviation Authority as the national regulator. The Act provides the framework for ensuring the safety and efficiency of civil aviation in Australia. One of its key provisions allows the Governor-General to make regulations for the purposes of the Act, particularly to safeguard air navigation. The Civil Aviation Safety Regulations 1998, made under the authority of the Act, enable the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific kinds of aircraft or aeronautical products, thereby ensuring that these meet the necessary safety standards. The issuance of ADs is a crucial mechanism for maintaining the continuing airworthiness of aircraft, aligning with international obligations under the Convention on International Civil Aviation. The authority to issue such directives ensures that Australia meets its international commitments and maintains high safety standards in its airspace.
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, ensuring the continuing safety and airworthiness of aircraft registered in Australia. Pursuant to section 98 of the Civil Aviation Act 1988, the Governor-General is empowered to make regulations for the purposes of the Act, particularly in the interests of air navigation safety, with regulation 39.001 authorising the Civil Aviation Safety Authority (CASA) to issue ADs for specific types of aircraft or aeronautical products. These directives are considered legislative instruments under the Legislative Instruments Act 2003, and they are subject to disallowance under the Acts Interpretation Act 1901. The geographic scope of these regulations is national, applying to all aircraft and aeronautical products within Australia, with additional international obligations under Annex 8 to the Convention on International Civil Aviation, which mandates the State of Design to provide necessary information to ensure the continuing airworthiness of aircraft types registered in other states. CASA, as the national airworthiness authority, assesses such information and, if appropriate, issues Australian ADs to enforce the requirements of the relevant State of Design. The process of issuing ADs often bypasses public consultation due to their alignment with international obligations, and they are not subject to a Regulatory Impact Statement. The ADs are issued by designated CASA officials in accordance with the Act’s provisions.
Key Provisions
The Civil Aviation Act 1988, through section 98, empowers the Governor-General to create regulations aimed at ensuring 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 airworthiness directives (ADs) for specific types of aircraft or aeronautical products. An AD, as defined under subregulation 39.001(5), is a disallowable instrument under section 46A of the Acts Interpretation Act 1901 and is therefore considered a legislative instrument as per section 6 of the Legislative Instruments Act 2003.
The obligations imposed by the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 on parties governed by these Acts are primarily centered around ensuring the continuing airworthiness of aircraft. According to Annex 8 to the Convention on International Civil Aviation, the State of Design—the country where the aircraft type is designed—bears the primary responsibility for the continuing airworthiness of that type. This State must provide necessary information to ensure that the type meets airworthiness standards, and this information is commonly conveyed through ADs. The State of Registry, the country where the aircraft is registered, must then develop or adopt requirements to ensure the continuing airworthiness of aircraft within its jurisdiction. When a State of Design issues an AD, the State of Registry, in this case CASA as Australia's national airworthiness authority, must assess the AD and, if appropriate, issue a corresponding Australian AD to enforce the design State’s requirements.
Failure to comply with the requirements set out in an airworthiness directive can result in serious consequences. Under the Civil Aviation Act 1988, non-compliance with ADs can lead to civil or criminal penalties. The specific penalties for breach can include fines and imprisonment, depending on the severity of the non-compliance. The exact penalties are not specified in the provided text, but generally, serious breaches can attract substantial fines and significant periods of imprisonment. Additionally, non-compliance can lead to the grounding of aircraft, which has severe operational and financial implications for the operators. Ensuring adherence to ADs is therefore crucial for maintaining the safety and airworthiness of aircraft.
