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.
Transport Canada has issued AD CF-2007-33 affecting Bombardier DHC-8-400 series aircraft. Canada is the State of Design for this type. CASA has assessed this AD and has issued Australian AD/DHC-8/136, which will become effective on 31 January 2008.
As this AD is issued because of Australia’s obligations under Convention on International Civil Aviation, and because it is issued in response to an AD raised by the relevant State of Design, no consultation of the Australian public has taken place on this AD. 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 Parliament of Australia, governs matters relating to the safety and efficiency of civil aviation within the country. This legislation was introduced to address the need for comprehensive regulation of civil aviation, ensuring safety, efficiency, and environmental protection. The Act empowers the Governor-General to make regulations necessary for air navigation safety, including the issuance of airworthiness directives. These directives serve as legislative instruments aimed at maintaining the continuing airworthiness of aircraft, in accordance with international standards set by the International Civil Aviation Organization (ICAO). The Civil Aviation Safety Regulations 1998 further outline the processes and requirements for the issuance of such directives by the Civil Aviation Safety Authority (CASA), Australia's national airworthiness authority. The policy objective is to ensure that all aircraft operating in Australian airspace meet the highest safety standards, reflecting Australia’s commitments under the Convention on International Civil Aviation.
Scope and Application
The Civil Aviation Safety Regulations 1998, under the Civil Aviation Act 1988, empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. These directives are a form of continuing airworthiness information, integral to ensuring the safety of air navigation in accordance with international standards set forth by the Convention on International Civil Aviation. The ADs are legislative instruments, subject to disallowance and the scrutiny of the Legislative Instruments Act 2003. The scope of these directives applies to all aircraft registered in Australia, imposing responsibilities on both the State of Design and the State of Registry to ensure compliance with international airworthiness standards. CASA, as Australia's national airworthiness authority, must act on directives issued by the State of Design to maintain the safety standards of aircraft operating within Australian jurisdiction. This process underscores the collaborative effort between contracting states under the Convention to uphold aviation safety. Notably, the issuance of ADs does not require public consultation or a Regulatory Impact Statement, reflecting their technical nature and the urgency often associated with ensuring the airworthiness of aircraft.
Key Provisions
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 provide the framework for the issuance of airworthiness directives (ADs) in Australia. Section 98 of the Act allows the Governor-General to make regulations to ensure 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 ADs for types of aircraft or aeronautical products. This regulatory power is crucial for maintaining the safety standards of aviation operations within Australia. An AD is considered a legislative instrument under the Legislative Instruments Act 2003, as it is a disallowable instrument under section 46A of the Acts Interpretation Act 1901.
Under these provisions, CASA has the responsibility to issue ADs when necessary to ensure the continuing airworthiness of aircraft registered in Australia. This obligation is particularly important given the international nature of aviation, where the State of Design holds the primary responsibility for the continuing airworthiness of an aircraft type, as outlined in Annex 8 to the Convention on International Civil Aviation. The State of Design must provide necessary information to other States of Registry, including Australia. CASA, as the national airworthiness authority, must then assess this information and, if appropriate, issue an Australian AD to mandate the requirements set by the State of Design. This ensures that Australian-registered aircraft meet the necessary safety standards as dictated by the international regulatory framework.
Compliance with ADs is mandatory for aircraft operators and other entities governed by the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998. Failure to adhere to the requirements set out in an AD can result in significant legal consequences. The Act and accompanying regulations impose stringent obligations on aircraft operators to ensure their aircraft meet the specified airworthiness standards. Non-compliance with ADs can lead to enforcement actions, including the potential grounding of aircraft, fines, and other penalties. The seriousness of these consequences underscores the importance of adhering to ADs to maintain the high safety standards expected in the aviation industry.
The Civil Aviation Safety Regulations 1998 also outline specific offences and penalties for breaches of ADs. While the Act does not detail the specific penalties for non-compliance with ADs, it does provide a framework under which CASA can take action against violators. The penalties can include substantial fines and, in severe cases, criminal charges against the responsible individuals or entities. The maximum penalties are determined based on the severity of the breach and can result in imprisonment for serious violations, reinforcing the critical nature of adhering to ADs to ensure the safety of air navigation.
