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.
CASA issued AD/BEECH 50/19, affecting Beech 50 model aircraft in 1971. CASA has reviewed this AD and as a result has decided to cancel it. The cancellation will become effective on 17 January 2008. No replacement AD is required, as the original unsafe condition is now addressed by AD/GENERAL/74 Amendment 1.
No consultation with the Australian public has taken place on this AD cancellation, because the cancellation results in a reduction of the regulatory burden. 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 establish a framework for the regulation of civil aviation in Australia, ensuring safety and efficiency within the aviation sector. The Act empowers the Governor-General to make regulations for the purposes of the Act and in the interests of the safety of air navigation. As part of this regulatory framework, the Civil Aviation Safety Regulations 1998 were introduced to provide detailed provisions governing various aspects of civil aviation safety. Under these regulations, the Civil Aviation Safety Authority (CASA) is authorised to issue airworthiness directives (ADs) for certain types of aircraft or aeronautical products, as outlined in regulation 39.001. These directives are legislative instruments, subject to disallowance under the Acts Interpretation Act 1901. The objective is to ensure that aircraft maintain their airworthiness, in line with international standards set by the Convention on International Civil Aviation. CASA’s role includes assessing and, if necessary, issuing Australian ADs to enforce the continuing airworthiness requirements mandated by the State of Design, reflecting Australia’s commitment to international aviation safety standards.
Scope and Application
The Civil Aviation Act 1988, and its subsidiary regulations, notably the Civil Aviation Safety Regulations 1998, govern the safety and airworthiness of aircraft within Australia. Under section 98 of the Act, the Governor-General has the authority to create regulations aimed at ensuring the safety of air navigation, and regulation 39.001 of the Civil Aviation Safety Regulations 1998 empowers the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. These ADs, being disallowable instruments, are also legislative instruments under the Legislative Instruments Act 2003. The ADs serve to maintain the continuing airworthiness of aircraft, a responsibility that is shared between the State of Design and the State of Registry as outlined in Annex 8 to the Convention on International Civil Aviation. CASA, as Australia's national airworthiness authority, is mandated to issue Australian ADs if required, ensuring compliance with international standards and addressing specific safety concerns. In the case of AD/BEECH 50/19, which was issued for Beech 50 model aircraft in 1971, CASA has determined that it can be cancelled due to the condition it was addressing being covered by another AD, thus reducing the regulatory burden without necessitating public consultation or a Regulatory Impact Statement.
Key Provisions
The main operative sections of this legislation, particularly section 98 of the Civil Aviation Act 1988, empower the Governor-General to make regulations for air navigation safety, while regulation 39.001 of the Civil Aviation Safety Regulations 1998 allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. Section 39.001(5) further clarifies that ADs are legislative instruments, subject to disallowance under the Acts Interpretation Act 1901. These provisions are essential for maintaining the safety standards of aircraft in Australia, ensuring that regulatory measures align with international standards set by the International Civil Aviation Organization (ICAO).
The obligations imposed by this Act and its regulations primarily focus on the State of Design and the State of Registry. The State of Design, as per Annex 8 to the Convention on International Civil Aviation, is responsible for the continuing airworthiness of an aircraft type and must provide necessary information to ensure the safety of aircraft types registered in other states. The State of Registry, on the other hand, is mandated to develop or adopt requirements for the continuing airworthiness of individual aircraft registered within its jurisdiction. CASA, as the national airworthiness authority, must review and, if necessary, issue Australian ADs to enforce the safety requirements outlined by the State of Design.
Offences or breaches of the provisions in this Act and its regulations can lead to significant civil and criminal consequences. While the specific offences and penalties are not detailed in the provided text, generally, under the Civil Aviation Act 1988, non-compliance with ADs can result in penalties for individuals and corporations. The maximum penalties may include substantial fines and, in severe cases, imprisonment. CASA's authority to issue ADs and enforce compliance ensures that all stakeholders adhere to stringent safety standards, thereby maintaining the overall safety of air navigation in Australia.
In summary, the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 establish a robust framework for ensuring the safety and airworthiness of aircraft through the issuance of ADs. The obligations placed on the State of Design and the State of Registry underscore the importance of international cooperation and regulatory oversight. The potential civil and criminal consequences for non-compliance serve as a deterrent, ensuring that all parties adhere to the stringent safety standards mandated by the legislation.
