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 issued AD 2007-26-12, affecting Robinson R44 model helicopters, in early 2008. The USA is the State of Design for this type. As a result of a request from industry, CASA has amended the equivalent Australian AD to allow the use of alternate methods of compliance. The amended AD, AD/R44/22 Amendment 4, will become effective on 28 August 2008. 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 in the Airworthiness Engineering Branch, on behalf of CASA, in accordance with subsection 84A (2) of the Act.
Overview
The Civil Aviation Act 1988 was enacted to provide a legislative framework for civil aviation in Australia, ensuring the safety and efficiency of air navigation and operations. Under section 98 of this Act, the Governor-General is empowered to make regulations for the Act's purposes, particularly to promote the safety of air navigation. In alignment with this, the Civil Aviation Safety Regulations 1998 allow the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for certain types of aircraft or aeronautical products. The ADs are considered disallowable instruments under the Acts Interpretation Act 1901, and thus, legislative instruments in accordance with the Legislative Instruments Act 2003. These directives are critical in maintaining the continuing airworthiness of aircraft types, a responsibility primarily held by the State of Design, while the State of Registry enforces these directives within its jurisdiction. CASA, as Australia’s national airworthiness authority, issues Australian ADs in response to directives from the State of Design, ensuring compliance with international standards set by the Convention on International Civil Aviation.
Scope and Application
The Civil Aviation Act 1988, supplemented by the Civil Aviation Safety Regulations 1998, provides the framework for the issuance of airworthiness directives (ADs) in Australia. These directives are legislative instruments made by the Civil Aviation Safety Authority (CASA), the national airworthiness authority, under regulation 39.001 of the Civil Aviation Safety Regulations 1998. Such ADs apply to all aircraft or aeronautical products registered in Australia and are issued to ensure the continuing airworthiness of these entities, in line with international obligations under the Convention on International Civil Aviation. This Act and its regulations have a national jurisdictional reach, applying to all aircraft registered in Australia, irrespective of the state or territory in which they are based. While ADs are legislative instruments that can be disallowed under the Acts Interpretation Act 1901, they do not require consultation with the public or a Regulatory Impact Statement, as determined by the Office of Best Practice Regulation. This streamlined process reflects the critical nature of ensuring airworthiness in alignment with international standards.
Key Provisions
The Civil Aviation Act 1988, through section 98, empowers the Governor-General to create regulations to ensure the safety of air navigation. This legislative authority extends to the Civil Aviation Safety Regulations 1998, specifically under regulation 39.001, which allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) concerning types of aircraft or aeronautical products. Subregulation 39.001(5) further classifies these ADs as disallowable instruments under section 46A of the Acts Interpretation Act 1901, and by virtue of section 6 of the Legislative Instruments Act 2003, ADs are recognized as legislative instruments.
These airworthiness directives serve as a means for states to maintain the continuing airworthiness of aircraft. The State of Design, as outlined in Annex 8 to the Convention on International Civil Aviation, bears the primary responsibility for the airworthiness of an aircraft type and must furnish necessary information to ensure its airworthiness to the State of Registry. The State of Registry, in turn, must implement or adopt requirements to ensure the continuing airworthiness of aircraft registered within its jurisdiction. For example, when a State of Design issues an AD for an aircraft type registered in Australia, CASA must review the directive and, if necessary, issue a corresponding Australian AD to enforce the required measures.
In cases where ADs are issued in response to directives from the State of Design, such as AD 2007-26-12 for Robinson R44 model helicopters issued by the US FAA in 2008, CASA must act to align Australian regulations with the international standards. In this instance, CASA amended the Australian AD to permit alternative methods of compliance, resulting in AD/R44/22 Amendment 4, which superseded the previous directive. This amendment reflects Australia’s commitment to international aviation standards and ensures consistency in airworthiness requirements.
Breaching the provisions of the Civil Aviation Safety Regulations 1998, including non-compliance with ADs, can result in significant legal consequences. Such breaches may be subject to civil penalties or criminal charges, depending on the severity of the violation. The specific penalties are determined by the nature of the offence and can include fines or imprisonment, as outlined in relevant sections of the Civil Aviation Act 1988 and other applicable legislation. Compliance with ADs is critical to maintaining the safety standards required by Australian and international aviation authorities.
