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 United States FAA has issued AD 2006-07-12 affecting Boeing 737 aircraft. The United States is the State of Design for this aircraft type. CASA has assessed this AD and has issued Australian AD/B737/286 which will become effective on 8 June 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 establish a comprehensive legal framework for ensuring the safety and efficiency of civil aviation in Australia. This Act, overseen by the Australian Parliament, aims to provide for the safe and efficient operation of aircraft, including the regulation of airworthiness standards. In line with this objective, the Civil Aviation Safety Regulations 1998 were introduced to enforce specific safety measures and procedures. One significant aspect of these regulations is the issuance of airworthiness directives (ADs), which are legislative instruments that mandate corrective actions to ensure the continuing airworthiness of aircraft. These ADs are often issued in response to international obligations, such as those under the Convention on International Civil Aviation, and typically do not require public consultation as they are aligned with international standards set by the State of Design. The Civil Aviation Safety Authority (CASA) issues these directives to comply with Australia's responsibilities under the Convention and to maintain the safety of aircraft registered in Australia.
Scope and Application
The Civil Aviation Safety Regulations 1998, under section 39.001, empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) to ensure the safety of air navigation in Australia. These ADs apply to specific kinds of aircraft or aeronautical products and are considered legislative instruments under the Legislative Instruments Act 2003. The ADs are typically issued in response to obligations under the Convention on International Civil Aviation, where the State of Design holds primary responsibility for the continuing airworthiness of an aircraft type. For aircraft registered in Australia, CASA, as the national airworthiness authority, must assess these directives and issue corresponding Australian ADs to enforce the required safety measures. This process ensures that Australian-registered aircraft comply with international safety standards and mandates specific maintenance or operational procedures as necessary.
Key Provisions
The Civil Aviation Act 1988, together with the Civil Aviation Safety Regulations 1998, provides the legislative framework within which airworthiness directives (ADs) are issued. Section 98 of the Act empowers the Governor-General to make regulations in the interests of air navigation safety, while regulation 39.001 of the Civil Aviation Safety Regulations 1998 specifically allows the Civil Aviation Safety Authority (CASA) to issue ADs for certain kinds of aircraft or aeronautical products. This regulation ensures that ADs serve as a crucial tool in maintaining the airworthiness of aircraft.
Under this Act and its associated regulations, CASA, as the national airworthiness authority, has the responsibility to ensure that aircraft registered in Australia meet the required safety standards. When an AD is issued by the State of Design—in this case, the United States for Boeing 737 aircraft—CASA must assess the information provided and, if deemed necessary, issue an Australian AD to enforce the requirements. This process is in line with Annex 8 of the Convention on International Civil Aviation, which mandates that the State of Design has the primary responsibility for the continuing airworthiness of an aircraft type, while the State of Registry (Australia, in this context) must ensure the ongoing airworthiness of individual aircraft.
The obligations imposed on CASA include the assessment of foreign ADs and the issuance of corresponding Australian ADs when necessary. This ensures that Australian aircraft comply with international safety standards. Furthermore, CASA must act in accordance with the legislative instruments act, which governs the creation and management of legislative instruments such as ADs. The AD issued in response to FAA AD 2006-07-12 is an example of CASA fulfilling its duty to maintain the safety of aircraft registered in Australia.
Failure to comply with ADs can result in serious consequences. Civil Aviation Safety Regulations 1998 and the Civil Aviation Act 1988 provide for potential offences and penalties for non-compliance with airworthiness directives. While specific penalties are not detailed in the provided text, non-compliance with ADs can lead to severe civil or criminal consequences, including fines or imprisonment. The seriousness of these penalties underscores the importance of adhering to the directives issued by CASA to ensure the safety of air navigation.
