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 2008-24-08 affecting Boeing B737 model aircraft. The USA is the State of Design for this type. CASA has assessed this AD and has issued Australian AD/B737/351, which will become effective on 12 February 2009.
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, 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 establish a comprehensive legal framework for the regulation of civil aviation in Australia, ensuring the safety, efficiency, and orderly development of aviation in the country. One of the key aspects of this Act is its provision for the issuance of airworthiness directives by the Civil Aviation Safety Authority (CASA), which acts as the national airworthiness authority. This mechanism is crucial for maintaining the continuing airworthiness of aircraft and aeronautical products, aligning with international standards set forth by the Convention on International Civil Aviation. The policy objective of the Act is to safeguard the public by ensuring that civil aviation operations are conducted safely and efficiently. The Civil Aviation Safety Regulations 1998 further support this objective by detailing the procedures and requirements for the issuance of airworthiness directives, which are legislative instruments subject to disallowance by Parliament. The introduction of such directives, particularly in response to international standards, underscores Australia's commitment to harmonised global aviation safety practices.
Scope and Application
The Civil Aviation Safety Regulations 1998, under section 98 of the Civil Aviation Act 1988, empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) concerning specific types of aircraft or aeronautical products to ensure the safety of air navigation. This legislative framework applies to all aircraft registered in Australia, irrespective of whether they are commercial, private, or military, and to all aeronautical products used in Australian-registered aircraft. Geographically, this regulation has a national reach, covering all airspace within Australia. Subregulation 39.001(5) of the Civil Aviation Safety Regulations 1998 classifies an AD as a disallowable instrument, thus making it a legislative instrument under the Legislative Instruments Act 2003. This AD extends Australia's obligations under the Convention on International Civil Aviation, specifically Annex 8, which places the responsibility of continuing airworthiness on the State of Design and mandates that the State of Registry develop or adopt requirements to ensure the continuing airworthiness of aircraft. Given these international obligations and the nature of ADs, no public consultation or Regulatory Impact Statement is required for this particular AD. It was issued by the acting Manager, Airframes & Structures in the Airworthiness Engineering Group on behalf of CASA, in line with the authority granted by subsection 84A(2) of the Act.
Key Provisions
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 provide the legal framework for issuing airworthiness directives (ADs). Section 98 of the Civil Aviation Act 1988 empowers the Governor-General to make regulations for the safety of air navigation, while regulation 39.001 of the Civil Aviation Safety Regulations 1998 allows the Civil Aviation Safety Authority (CASA) to issue ADs for specific types of aircraft or aeronautical products. These ADs are legislative instruments and can be disallowed under section 46A of the Acts Interpretation Act 1901. Additionally, subregulation 39.001(5) further defines ADs as disallowable instruments. This legislative mechanism ensures that CASA can swiftly implement necessary safety measures without the need for extensive parliamentary scrutiny.
The obligations imposed by these regulations on parties, particularly CASA, are significant. Under Annex 8 to the Convention on International Civil Aviation, the State of Design has a primary responsibility for the continuing airworthiness of aircraft types. CASA, as Australia’s national airworthiness authority, must assess and, if necessary, issue corresponding ADs when the State of Design issues an AD. This ensures that Australian-registered aircraft meet international safety standards. Moreover, the State of Registry of individual aircraft must also develop or adopt requirements to ensure the continuing airworthiness of the aircraft on its registry. This dual responsibility ensures that both design and registry states contribute to maintaining the safety of aircraft in operation.
Non-compliance with ADs can lead to serious consequences. While the specific provisions regarding penalties are not detailed in the provided text, it is well-established within the framework of civil aviation law that breaches of safety regulations can result in substantial penalties. These can include fines, imprisonment, or both, depending on the severity of the breach. The regulatory regime ensures that both individuals and entities are held accountable for failing to adhere to mandated safety measures, thereby maintaining the high standards of aviation safety required under international and domestic law. CASA’s authority to issue and enforce ADs is critical in preventing accidents and ensuring the safety of air navigation.
