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/CESSNA 310/45 affecting Cessna 310 aircraft. CASA has assessed this AD and as a result has cancelled Australian AD/CESSNA 310/45. The cancellation will become effective on 8 May 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 Acting Manager, Systems and New Technologies in the Airworthiness Engineering Branch, on behalf of CASA, in accordance with subsection 84A (2) of the Act.
Overview
The Civil Aviation Act 1988, enacted by the Australian Parliament, governs civil aviation safety and aims to ensure the safety of air navigation within the nation's airspace. The Act empowers the Governor-General to make regulations for the purposes of the Act, particularly in matters concerning the safety of air navigation. One significant aspect of the Act is the regulation of airworthiness directives (ADs) through the Civil Aviation Safety Regulations 1998. These regulations enable the Civil Aviation Safety Authority (CASA) to issue ADs to maintain the continuing airworthiness of aircraft types and aeronautical products. The objective of these regulations is to align with international standards and ensure that the continuing airworthiness of aircraft is managed effectively, in line with obligations under the Convention on International Civil Aviation.
Under the framework established by the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998, CASA is responsible for assessing and, where necessary, issuing ADs based on directives from the aircraft's State of Design. This legislative process ensures that Australian aircraft meet both domestic and international safety standards. The legislative instrument for ADs is governed by the Legislative Instruments Act 2003, and any changes or cancellations of these directives are made to uphold the highest safety standards without the need for public consultation, as determined by the Office of Best Practice Regulation.
Scope and Application
The Civil Aviation Act 1988 applies to various entities involved in the aviation industry, including aircraft operators, manufacturers, and air navigation service providers, as well as individuals such as pilots and engineers. The Act and its associated regulations, including the Civil Aviation Safety Regulations 1998, are designed to ensure the safety of air navigation within Australia and its territories. Specifically, regulation 39.001 of the Civil Aviation Safety Regulations empowers the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for particular types of aircraft or aeronautical products, which are considered legislative instruments under the Legislative Instruments Act 2003. These ADs are intended to mandate safety measures and ensure the continuing airworthiness of aircraft registered in Australia, aligning with international standards set by the Convention on International Civil Aviation. The geographic reach of these regulations is national, applying to all aircraft within Australian jurisdiction. However, the Act and its regulations may also consider international obligations and directives issued by the State of Design, which is responsible for the continuing airworthiness of an aircraft type. The State of Registry, including CASA in Australia, must ensure that these international directives are appropriately assessed and implemented to maintain safety standards.
Key Provisions
The Civil Aviation Act 1988 (section 98) empowers the Governor-General to create regulations for the Act's purposes and in the interest of air navigation safety. Under regulation 39.001 of the Civil Aviation Safety Regulations 1998, the Civil Aviation Safety Authority (CASA) is authorised to issue airworthiness directives (ADs) for certain types of aircraft or aeronautical products. This regulation allows CASA to mandate specific requirements to ensure the safety and airworthiness of the aircraft.
Obligations under this Act require CASA to assess any ADs issued by the State of Design and, if necessary, to issue corresponding Australian ADs. This ensures that Australian aircraft comply with international safety standards. The State of Registry, which is the country where the aircraft is registered, is responsible for the ongoing airworthiness of the aircraft and must develop or adopt requirements to meet these standards. Additionally, under Annex 8 of the Convention on International Civil Aviation, the State of Design has the responsibility to provide any necessary information to maintain the airworthiness of an aircraft type.
Under the Civil Aviation Safety Regulations 1998, ADs are considered legislative instruments and can be disallowed under section 46A of the Acts Interpretation Act 1901. The AD/CESSNA 310/45, issued by CASA, was assessed and subsequently cancelled due to the resolution of the unsafe condition it was intended to address. This cancellation took effect on 8 May 2008, and no replacement AD was necessary. The cancellation aligns with Australia’s obligations under the Convention on International Civil Aviation, and no public consultation was required. The Office of Best Practice Regulation has also determined that ADs do not necessitate a Regulatory Impact Statement.
The AD was issued by the Acting Manager of Systems and New Technologies in the Airworthiness Engineering Branch on behalf of CASA, in accordance with subsection 84A(2) of the Act. In terms of penalties and consequences, the Civil Aviation Act 1988 does not specify particular penalties for breaches of ADs. However, non-compliance with ADs can result in severe consequences, including the potential grounding of aircraft, enforcement actions by CASA, and in some cases, civil or criminal penalties if the non-compliance leads to accidents or other safety incidents.
