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 73-18-01 affecting Convair 340, 440, 580 and 640 model aircraft. The USA is the State of Design for these types. CASA has assessed this AD and has issued Australian AD/CONVAIR/8, which will become effective on 11 May 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 for the regulation of civil aviation in Australia, particularly focusing on safety and airworthiness. This Act empowers the Governor-General to make regulations, including those concerning the safety of air navigation. One significant regulatory tool under this Act is the issuance of airworthiness directives (ADs) by the Civil Aviation Safety Authority (CASA), as outlined in the Civil Aviation Safety Regulations 1998. ADs are critical for ensuring the continuing airworthiness of aircraft and aeronautical products, aligning with international standards set by the Convention on International Civil Aviation. The Civil Aviation Act 1988 addresses the need for a robust and internationally compliant regulatory framework to maintain high safety standards in Australian civil aviation. The policy objective of the Act is to safeguard public safety and ensure the efficient operation of civil aviation through stringent regulatory measures.
Scope and Application
The Civil Aviation Safety Regulations 1998, under the Civil Aviation Act 1988, empowers the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific kinds of aircraft or aeronautical products. These ADs serve as legislative instruments under the Legislative Instruments Act 2003 and aim to ensure the continuing airworthiness of aircraft in line with Australia’s obligations under the Convention on International Civil Aviation. This legislation applies to aircraft registered in Australia and mandates that the State of Registry, in this case CASA, must assess and implement ADs issued by the State of Design, ensuring compliance with international standards. The issuance of ADs is a direct consequence of Australia’s commitment to international aviation safety protocols, and thus, public consultation is generally not required for such measures. Additionally, the Office of Regulatory Review has determined that ADs do not necessitate a Regulatory Impact Statement, streamlining the process for issuing these critical safety directives.
Key Provisions
The Civil Aviation Act 1988, supplemented by the Civil Aviation Safety Regulations 1998, provides the framework for issuing airworthiness directives (ADs) to ensure the safety of air navigation (s. 98, reg. 39.001). Section 39.001(5) of the Civil Aviation Safety Regulations specifies that an AD is a disallowable instrument under section 46A of the Acts Interpretation Act 1901, and therefore constitutes a legislative instrument according to section 6 of the Legislative Instruments Act 2003. These regulations mandate that the State of Design is responsible for the continuing airworthiness of aircraft types and must provide necessary information to the States of Registry (Annex 8 to the Convention on International Civil Aviation). Consequently, the State of Registry, such as CASA in Australia, must develop or adopt requirements to maintain the airworthiness of aircraft registered in their jurisdiction.
The obligations imposed by these regulations on the parties involved are multifaceted. The State of Design must issue ADs to address safety issues, which the State of Registry must then assess and, if necessary, translate into local directives. For instance, the United States, as the State of Design for the Convair 340, 440, 580, and 640 models, issued AD 73-18-01. CASA, as Australia’s national airworthiness authority, assessed this directive and issued Australian AD/CONVAIR/8, which will take effect on 11 May 2006. This process ensures that safety measures are uniformly implemented across international borders, aligning with Australia's obligations under the Convention on International Civil Aviation.
The Civil Aviation Act and the associated regulations impose strict requirements and consequences for non-compliance. Any breaches of ADs can lead to severe civil and criminal penalties. For instance, failure to comply with an AD can result in aircraft being grounded or operations being suspended until the required actions are completed. The maximum penalties for non-compliance may include substantial fines and, in some cases, imprisonment, depending on the severity of the breach and its impact on aviation safety. Such measures underscore the importance of adhering to ADs to maintain the highest safety standards in air navigation.
