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 2006-09-09 affecting Boeing B767 model aircraft. The USA is the State of Design for this type. CASA has assessed this AD and has issued Australian AD/B767/222, which will become effective on 6 July 2006.
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 Regulatory Review has determined that ADs do not require a Regulatory Impact Statement.
The AD has been made by the Manager, Airframes in the Manufacturing, Certification and New Technologies Office, on behalf of CASA, in accordance with subsection 84A (2) of the Act.
Overview
The Civil Aviation Act 1988 was enacted to address the need for a robust framework governing the safety and regulation of civil aviation in Australia. The Act empowers the Governor-General to issue regulations, which in turn facilitate the oversight and maintenance of airworthiness standards by the Civil Aviation Safety Authority (CASA). The Civil Aviation Safety Regulations 1998 further elaborate on the regulatory mechanisms, including the issuance of airworthiness directives (ADs) to ensure the ongoing airworthiness of aircraft types. These directives, being legislative instruments, are issued under the authority of the Civil Aviation Act and the Acts Interpretation Act 1901. The policy objective underpinning these regulations is to harmonise Australia’s approach with international standards set forth by the International Civil Aviation Organization (ICAO), ensuring that Australia meets its international obligations under the Convention on International Civil Aviation. CASA, as the national airworthiness authority, plays a pivotal role in assessing and implementing these directives, thereby maintaining the safety and reliability of aircraft operating within Australian airspace.
Scope and Application
The Civil Aviation Act 1988, supplemented by the Civil Aviation Safety Regulations 1998, encompasses the issuance of airworthiness directives (ADs) by the Civil Aviation Safety Authority (CASA) to ensure the safety of air navigation. Under section 98 of the Act, the Governor-General has the authority to make regulations for the safety of air navigation, and regulation 39.001 of the Civil Aviation Safety Regulations 1998 specifically empowers CASA to issue ADs for kinds of aircraft or aeronautical products. This regulation also stipulates that ADs are disallowable instruments under section 46A of the Acts Interpretation Act 1901, thereby classifying them as legislative instruments. In accordance with Annex 8 of the Convention on International Civil Aviation, the State of Design holds the responsibility for the continuing airworthiness of an aircraft type and must provide necessary information to ensure compliance. The State of Registry, in this case CASA for Australia, must then assess this information and, if necessary, issue corresponding ADs to enforce the requirements set by the State of Design. This legislative framework ensures that Australia adheres to international civil aviation standards and maintains the safety of its aircraft.
Key Provisions
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 provide the legal framework for the issuance of airworthiness directives (ADs). Under section 98 of the Act, the Governor-General has the authority to make regulations that serve the safety of air navigation. 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. This regulatory mechanism ensures that the necessary safety measures are implemented across the aviation industry.
The obligations imposed by these regulations require CASA, as Australia’s national airworthiness authority, to carefully assess any ADs issued by the State of Design of an aircraft type. When the State of Design, such as the United States for Boeing B767 model aircraft, issues an AD, CASA must evaluate the information provided and determine if an Australian AD is necessary. This ensures that all aircraft registered in Australia comply with the required safety standards. The State of Registry is also obligated to develop or adopt requirements that ensure the continuing airworthiness of aircraft under its jurisdiction, reinforcing the shared responsibility for aviation safety between the State of Design and the State of Registry.
The implications of non-compliance with ADs are significant. Failure to adhere to the mandates set out in an AD can result in severe consequences, including civil or criminal penalties. While the specific penalties are not outlined in the text, it is understood that non-compliance can lead to enforcement actions, fines, or even grounding of the aircraft. The severity of the penalties reflects the critical importance of airworthiness directives in maintaining the safety and reliability of aircraft.
The process of issuing an AD does not typically involve public consultation, as it is based on international obligations under the Convention on International Civil Aviation and the specific requirements of the State of Design. The AD is issued by the Manager, Airframes in CASA’s Manufacturing, Certification and New Technologies Office, in accordance with the legislative framework provided by the Civil Aviation Act 1988. This streamlined process ensures that safety directives are communicated and implemented without unnecessary delays, thereby safeguarding the interests of all stakeholders in the aviation industry.
