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 Civil Aviation Safety Authority or its predecessors issued AD/BEECH 95/20 affecting Beechcraft 95 model aircraft. CASA has assessed this AD and as a result has cancelled Australian AD/BEECH 95/20. The cancellation will become effective on 31 July 2008. No replacement AD is required, as the unsafe condition no longer exists.
As this AD has been cancelled because of Australia’s obligations under the Convention on International Civil Aviation, no consultation with the Australian public has taken place on this AD cancellation. 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, Airframe and Structures, 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 regulate civil aviation in Australia with a focus on safety, efficiency and international standards. The Civil Aviation Safety Regulations 1998 further detail the requirements for airworthiness, including the issuance of airworthiness directives (ADs). An AD is a legislative instrument issued by the Civil Aviation Safety Authority (CASA) to mandate safety standards for specific types of aircraft or aeronautical products. This ensures that aircraft on the Australian Register maintain their airworthiness in compliance with international standards, particularly those set forth by the International Civil Aviation Organization (ICAO). Under this framework, CASA issued AD/BEECH 95/20 for Beechcraft 95 model aircraft, which has since been cancelled due to the resolution of the identified unsafe condition. This cancellation aligns with Australia's obligations under the Convention on International Civil Aviation and does not require public consultation or a Regulatory Impact Statement. The AD was made by the Manager, Airframe and Structures, in the Airworthiness Engineering Branch of CASA, in accordance with the Act.
Scope and Application
The Civil Aviation Act 1988, in conjunction with the Civil Aviation Safety Regulations 1998, provides the framework for the issuance of airworthiness directives (ADs) within Australia, as a means to ensure the safety of air navigation. Under section 98 of the Civil Aviation Act 1988, the Governor-General has the authority to make regulations for air navigation safety, and regulation 39.001 of the Civil Aviation Safety Regulations 1998 empowers the Civil Aviation Safety Authority (CASA) to issue ADs for specific types of aircraft or aeronautical products. These ADs are legislative instruments that can be disallowed under section 46A of the Acts Interpretation Act 1901. The State of Design is responsible for the continuing airworthiness of aircraft types and must provide necessary information to the State of Registry to ensure compliance with international standards, such as those outlined in Annex 8 to the Convention on International Civil Aviation. Consequently, when a State of Design issues an AD, CASA must evaluate the information and, if deemed necessary, issue an Australian AD to enforce the requirements. The AD/BEECH 95/20 affecting Beechcraft 95 model aircraft, initially issued by CASA, has been cancelled due to the elimination of the unsafe condition, with no replacement AD necessary. This cancellation aligns with Australia's international obligations and has not required public consultation or a Regulatory Impact Statement.
Key Provisions
The Civil Aviation Act 1988, supplemented by the Civil Aviation Safety Regulations 1998, empowers the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specified types of aircraft or aeronautical products (section 98 and regulation 39.001). An AD is a legislative instrument that serves as a crucial mechanism for maintaining the airworthiness of aircraft and ensuring safety in air navigation (subregulation 39.001(5)). These directives are aligned with the responsibilities of the State of Design and the State of Registry under Annex 8 to the Convention on International Civil Aviation, which mandates that the State of Design must provide necessary information for continuing airworthiness, and the State of Registry must implement requirements to ensure the same.
The obligations placed on the parties governed by this Act include CASA's responsibility to assess information from the State of Design regarding ADs and issue Australian ADs as appropriate to ensure compliance with safety standards. CASA, as Australia's national airworthiness authority, must act in accordance with Australia's obligations under the Convention on International Civil Aviation. This includes cancelling ADs when the unsafe conditions they address no longer exist, as demonstrated by the cancellation of AD/BEECH 95/20 affecting Beechcraft 95 model aircraft, which will become effective on 31 July 2008.
The Civil Aviation Safety Regulations 1998 also detail that when an AD has been cancelled due to obligations under the Convention, there is no requirement for consultation with the Australian public or the creation of a Regulatory Impact Statement. The cancellation of ADs, such as AD/BEECH 95/20, is managed by the Manager, Airframe and Structures, in the Airworthiness Engineering Branch, on behalf of CASA, in line with subsection 84A(2) of the Act.
Breaching the provisions of the Civil Aviation Act 1988 or the Civil Aviation Safety Regulations 1998 can result in various civil and criminal consequences. Offences under the Act can lead to substantial penalties, although the exact maximum penalties are not specified within the provided text. Compliance with ADs is critical, as failure to adhere to mandated airworthiness directives can result in severe consequences for aircraft operators and manufacturers, potentially impacting public safety and leading to legal repercussions.
