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 2006-08-09 affecting Airtractor AT800 model aircraft. The USA is the State of Design for this type. CASA has assessed this AD and as a result has cancelled Australian AD/AT 800/3, Amendment 2. The cancellation will become effective on 5 May 2006. This AD has been replaced by AD/AT 800/7.
As this AD has been cancelled because of Australia’s obligations under the Convention on International Civil Aviation, and because it is cancelled in response to an AD raised by the relevant State of Design, no consultation with the Australian public has taken place on this AD cancellation. 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, enacted by the Parliament of Australia, addresses the safety of air navigation and establishes the regulatory framework for civil aviation within Australia. One of the Act's key provisions is the authority it grants the Governor-General to make regulations that promote the safety of air navigation. Specifically, the Act allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for various types of aircraft or aeronautical products as per the Civil Aviation Safety Regulations 1998. These directives are essential for ensuring the continuing airworthiness of aircraft, aligning with international standards set by the Convention on International Civil Aviation. The policy objective is to harmonise Australian regulations with international standards and ensure that aircraft registered in Australia meet necessary safety requirements. This approach not only enhances the safety of air navigation but also facilitates international cooperation in civil aviation.
Scope and Application
The Civil Aviation Act 1988, as applied through the Civil Aviation Safety Regulations 1998, establishes the framework for ensuring the safety of air navigation and the continuing airworthiness of aircraft within Australia. Specifically, section 98 of the Act empowers the Governor-General to create regulations for air navigation safety, while regulation 39.001 allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. These ADs are considered legislative instruments under the Legislative Instruments Act 2003. The ADs are integral to maintaining the airworthiness of aircraft as per Annex 8 of the Convention on International Civil Aviation, with the State of Design responsible for issuing such directives. In Australia, CASA, as the national airworthiness authority, must evaluate these international directives and, if necessary, issue corresponding Australian ADs to enforce the requirements on aircraft registered in Australia. The geographic reach of these regulations is national, applying to all aircraft registered in Australia, and they extend to international obligations under the Convention on International Civil Aviation. Notably, these regulations do not require public consultation or a Regulatory Impact Statement when cancelling ADs in response to international directives, as per the determinations of the Office of Regulatory Review.
Key Provisions
The Civil Aviation Safety Regulations 1998, under regulation 39.001, empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. These ADs are issued to ensure the continuing airworthiness of aircraft in line with safety standards and are considered legislative instruments under the Legislative Instruments Act 2003. This regulatory mechanism is crucial for maintaining the safety standards of aircraft registered in Australia, ensuring compliance with international civil aviation conventions and agreements. The State of Design, which in this case is the USA for the Airtractor AT800 model, holds the primary responsibility for the continuing airworthiness of the aircraft type and must provide necessary information to the States of Registry, including Australia.
The obligations imposed on CASA under these regulations are significant. CASA must assess any AD issued by the State of Design to determine its relevance and applicability to aircraft registered in Australia. If an AD from another country affects an aircraft type registered in Australia, CASA must either adopt the AD or issue a corresponding Australian AD to enforce the same safety measures. This process ensures that all aircraft operating in Australian airspace meet the required safety standards, aligning with the international obligations under the Convention on International Civil Aviation. CASA’s role is to balance the need for stringent safety measures with the practicalities of aircraft operation in Australia.
Failure to comply with the airworthiness directives can result in serious consequences. Under the Civil Aviation Act 1988, non-compliance with ADs can lead to enforcement actions against the aircraft operators or owners. These actions can include fines, suspension or revocation of airworthiness certificates, or other regulatory penalties. The severity of these penalties reflects the importance of adhering to airworthiness directives, which are designed to prevent accidents and ensure the safety of passengers and crew. CASA has the authority to take immediate action against any non-compliant aircraft, highlighting the critical nature of these safety regulations.
The maximum penalties for breaches of airworthiness directives can be substantial. According to the Civil Aviation Act 1988, individuals or corporations found guilty of non-compliance can face fines up to $210,000 for individuals and $1,050,000 for corporations, depending on the severity of the breach. Additionally, persistent or serious violations can lead to imprisonment for individuals, with terms extending up to five years. These stringent penalties underscore the importance of adhering to airworthiness directives and the commitment of Australian authorities to maintain high safety standards in civil aviation.
