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 2002-258 affecting Dornier 328 model aircraft. Germany is the State of Design for this type. CASA has assessed this AD and has issued Australian AD/DO 328/46, which will become effective on 16 March 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 comprehensive legal framework for civil aviation in Australia, addressing issues related to the safety and regulation of air navigation. This Act allows the Governor-General to make regulations that serve the interests of air navigation safety. Under this Act, the Civil Aviation Safety Regulations 1998 were established, which empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific kinds of aircraft or aeronautical products. The purpose of these directives is to ensure the continuing airworthiness of aircraft, aligning with international standards set forth by the Convention on International Civil Aviation. This legislation is designed to uphold safety standards in Australia's aviation sector, in line with global commitments and obligations.
Scope and Application
The Civil Aviation Safety Regulations 1998, under the Civil Aviation Act 1988, empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for certain types of aircraft or aeronautical products. These directives serve as legislative instruments that mandate compliance to ensure the continuing airworthiness of aircraft registered in Australia. The ADs are issued in accordance with Australia's obligations under the Convention on International Civil Aviation and typically follow directives issued by the State of Design, which holds overall responsibility for the continuing airworthiness of the aircraft type. CASA, as Australia's national airworthiness authority, assesses the information from the State of Design and issues corresponding Australian ADs if appropriate. The application of these ADs is geographically limited to aircraft registered within Australia, and they do not require public consultation or a Regulatory Impact Statement, as determined by the Office of Regulatory Review. The issuance of these directives is a critical measure to maintain safety standards in civil aviation as per international obligations and Australian regulations.
Key Provisions
The Civil Aviation Act 1988, particularly 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 further enables CASA to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. These ADs are considered disallowable instruments under section 46A of the Acts Interpretation Act 1901 and are legislative instruments as per section 6 of the Legislative Instruments Act 2003. Annex 8 to the Convention on International Civil Aviation assigns the State of Design the overarching responsibility for the continuing airworthiness of an aircraft type, requiring it to provide necessary information to the States of Registry. States of Registry must then develop or adopt requirements to ensure the continuing airworthiness of aircraft.
Under these regulations, CASA, as Australia’s national airworthiness authority, must assess information from ADs issued by States of Design and, if deemed necessary, issue corresponding Australian ADs to enforce the requirements. This process ensures that Australian aircraft meet international safety standards. For instance, the German LBA issued AD 2002-258 concerning Dornier 328 model aircraft, prompting CASA to issue Australian AD/DO 328/46, which will take effect on 16 March 2006. Given that this AD is issued in compliance with Australia's international obligations and in response to an AD from the relevant State of Design, no public consultation has been conducted. Moreover, the Office of Regulatory Review has determined that ADs do not require a Regulatory Impact Statement.
The issuance of these ADs imposes specific obligations on both States of Design and States of Registry. The State of Design must ensure that any identified safety issues are communicated to the relevant States of Registry and provide the necessary information to maintain the continuing airworthiness of the aircraft. The State of Registry, in this case CASA, must then assess this information and, if necessary, issue a corresponding Australian AD to mandate the required safety measures. This process ensures that all parties involved in the design and operation of aircraft are actively engaged in maintaining safety standards. Failure to comply with these obligations can lead to significant safety risks, as mandated by the overarching requirements of the Convention on International Civil Aviation.
In terms of consequences for non-compliance, breaches of the ADs can result in various penalties. While the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 do not explicitly detail specific penalties for non-compliance with ADs, non-compliance with airworthiness regulations generally can lead to severe civil and criminal penalties. Civil penalties may include fines, suspension, or revocation of an aircraft's certificate of airworthiness. Criminal penalties could involve imprisonment, depending on the severity of the breach and the extent of any resulting harm. These consequences underscore the critical importance of adhering to ADs to ensure the safety and airworthiness of aircraft.
