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/L200/4 affecting Morava L200 series aeroplanes. CASA has assessed this AD and as a result has cancelled Australian AD/L200/4. The cancellation will become effective on
2 July 2009. 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 Group, on behalf of CASA, in accordance with subsection 84A (2) of the Act.
Overview
The Civil Aviation Act 1988 was enacted to provide for the safety of civil aviation in Australia. The Act grants the Governor-General the power to make regulations that contribute to the safety of air navigation. One such regulation is detailed in the Civil Aviation Safety Regulations 1998, which empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific kinds of aircraft or aeronautical products. These directives are crucial for maintaining the continuing airworthiness of aircraft as per international standards set by the Convention on International Civil Aviation. The ADs are legislative instruments that must be assessed by CASA when issued by the State of Design and, if necessary, translated into Australian directives. The Act ensures that CASA, as Australia’s national airworthiness authority, discharges its responsibility to monitor and mandate the continuing airworthiness of aircraft registered in Australia, thereby upholding both national and international safety standards.
Scope and Application
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 provide the framework for the regulation of civil aviation in Australia, with a particular emphasis on ensuring the safety of air navigation. The Act empowers the Governor-General to make regulations for the safety of air navigation, and under regulation 39.001, the Civil Aviation Safety Authority (CASA) is authorised to issue airworthiness directives (ADs) for kinds of aircraft or aeronautical products. This regulatory power extends to all aircraft registered in Australia, irrespective of whether the aircraft is operated domestically or internationally, thereby ensuring that safety standards are uniformly applied across the nation. ADs are considered legislative instruments under the Legislative Instruments Act 2003 and serve as a crucial mechanism for communicating continuing airworthiness information to aircraft operators and maintenance providers. These directives are issued in accordance with international standards set by the International Civil Aviation Organization (ICAO) and are subject to Australia’s obligations under the Convention on International Civil Aviation, which mandates that the State of Design retains responsibility for the continuing airworthiness of an aircraft type. CASA, as Australia’s national airworthiness authority, must assess any ADs issued by the State of Design and may issue corresponding Australian ADs to enforce compliance with safety standards. The process of issuing, amending, or cancelling ADs is conducted by CASA in accordance with the Civil Aviation Act 1988, ensuring that safety directives are implemented efficiently and effectively.
Key Provisions
The Civil Aviation Act 1988, in particular section 98, empowers the Governor-General to make regulations for the safety of air navigation. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 grants the Civil Aviation Safety Authority (CASA) the authority to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. These ADs are a form of legislative instrument, as detailed in subregulation 39.001(5) and section 46A of the Acts Interpretation Act 1901. They are integral to ensuring that aircraft remain airworthy throughout their operational life.
Under the obligations imposed by the Civil Aviation Safety Regulations 1998, the State of Design, which is the country where the aircraft type is designed, has the primary responsibility for ensuring the continuing airworthiness of that aircraft type. This responsibility includes providing any necessary information to the State of Registry, which is the country where the aircraft is registered. In Australia, CASA, as the national airworthiness authority, must assess any airworthiness directives issued by the State of Design. If appropriate, CASA is required to issue an Australian AD to enforce the requirements specified by the State of Design.
An example of this process is the issuance and subsequent cancellation of AD/L200/4, which pertained to Morava L200 series aeroplanes. CASA, after assessment, determined that the unsafe condition addressed by this AD no longer existed and consequently cancelled the directive, effective from 2 July 2009. As this cancellation aligns with Australia's obligations under the Convention on International Civil Aviation, no public consultation was conducted, and the Office of Best Practice Regulation has determined that ADs do not require a Regulatory Impact Statement.
In terms of compliance and enforcement, breaches of airworthiness directives or failure to adhere to mandated requirements can result in severe penalties. CASA has the authority to take various enforcement actions, including grounding aircraft, imposing fines, and pursuing legal action against individuals or companies that fail to comply with ADs. The maximum penalties for non-compliance can include substantial fines and, in serious cases, imprisonment, reflecting the critical importance of air safety and the high stakes involved in aviation operations.
