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 2009-04-06 affecting Boeing B747 model aircraft. The USA is the State of Design for this type. CASA has assessed this AD and has issued Australian AD/B747/314, Amendment 1, which will become effective on 7 May 2009. This AD cancels and replaces the previous issue.
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 Manager, Airframes & 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 a comprehensive legal framework for civil aviation in Australia, ensuring safety and efficiency in air navigation. This legislation empowers the Governor-General to make regulations necessary for the safety of air navigation, including the issuance of airworthiness directives by the Civil Aviation Safety Authority (CASA). The 1988 Act is underpinned by Australia's commitment to international civil aviation standards, particularly those established by the Convention on International Civil Aviation, which mandates that the State of Design has the primary responsibility for ensuring the continuing airworthiness of aircraft types. CASA, as Australia's national airworthiness authority, must therefore issue corresponding directives when necessary, as demonstrated by the recent issuance of AD/B747/314, Amendment 1, which aligns with a directive from the United States Federal Aviation Administration. The policy objective of these regulations is to maintain high safety standards in civil aviation by ensuring that all aircraft registered in Australia meet the necessary airworthiness criteria, thereby protecting public safety and fulfilling Australia's international obligations.
Scope and Application
The Civil Aviation Safety Regulations 1998, under the authority of 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 to ensure safety in air navigation. This regulatory framework is applicable to all aircraft registered in Australia, making CASA responsible for assessing and implementing ADs issued by the State of Design for a particular aircraft type, ensuring compliance with international standards set forth by the Convention on International Civil Aviation. The ADs are legislative instruments subject to disallowance and are developed in accordance with Annex 8 of the Convention, which mandates the State of Design's responsibility for the continuing airworthiness of an aircraft type, and the State of Registry's obligation to implement necessary requirements for airworthiness. Exemptions and thresholds are not specified in this particular AD, which was issued in response to an AD from the United States Federal Aviation Administration affecting Boeing B747 model aircraft, reflecting Australia’s commitment to international aviation safety standards without necessitating public consultation or a Regulatory Impact Statement.
Key Provisions
The Civil Aviation Act 1988, in particular section 98, empowers the Governor-General to establish regulations conducive to the safety of air navigation. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 authorises the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. It is noteworthy that subregulation 39.001(5) designates ADs as disallowable instruments under section 46A of the Acts Interpretation Act 1901, making them legislative instruments as per section 6 of the Legislative Instruments Act 2003. This legislative framework is aligned with Annex 8 to the Convention on International Civil Aviation, which stipulates that the State of Design, which in this context is the country where the aircraft type is designed, bears the responsibility for the continuing airworthiness of that type and must supply necessary information to ensure its safety.
The obligations under this legislation for parties involved are multifaceted. The State of Design must ensure the continuing airworthiness of the aircraft type and provide essential information to the States of Registry. States of Registry, including Australia, must then develop or adopt requirements to maintain the airworthiness of aircraft within their jurisdiction. When an AD is issued by a State of Design, such as the US Federal Aviation Administration (FAA) for a Boeing B747, CASA, acting as Australia’s national airworthiness authority, must evaluate the directive and, if deemed appropriate, issue an Australian AD to enforce the requirements specified by the State of Design. This process ensures that Australian aircraft comply with international safety standards.
Failure to comply with the provisions set out in an AD can lead to significant legal and safety consequences. Under the Civil Aviation Act 1988, non-compliance with ADs can result in civil penalties. The specific penalties are not detailed in the explanatory statement, but generally, these could include fines and other civil sanctions. Additionally, from a criminal perspective, serious breaches of airworthiness regulations could lead to prosecution, potentially resulting in imprisonment. The exact penalties, however, are determined by the courts based on the severity of the breach and the context of the violation.
Given the international nature of aviation and the critical importance of maintaining airworthiness, the regulatory process ensures that all stakeholders are aware of their responsibilities. The legislative framework is designed to harmonise with international standards set by ICAO, thereby promoting global safety and uniformity in aviation practices. This approach underscores the importance of coordinated regulatory efforts among States of Design and States of Registry to maintain high standards of aviation safety.
