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 2006-10-17 affecting Boeing 737 series aircraft. The United States is the State of Design for these types. CASA has assessed this AD and has issued Australian AD/B737/290, which will become effective on 3 August 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, New Technologies and Systems, 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 provide a legislative framework for the regulation of civil aviation in Australia, with a focus on ensuring the safety and efficiency of air navigation. One of the critical mechanisms established under this Act is the ability to issue airworthiness directives (ADs) through the Civil Aviation Safety Regulations 1998. The Civil Aviation Safety Regulations 1998, specifically regulation 39.001, empower the Civil Aviation Safety Authority (CASA) to issue ADs for particular types of aircraft or aeronautical products. These ADs serve as legislative instruments that mandate specific safety measures and maintenance requirements to ensure the continuing airworthiness of aircraft in compliance with international standards. The Act was introduced to address the need for a robust regulatory framework to manage and enforce civil aviation safety standards in Australia, aligning with international obligations under the Convention on International Civil Aviation. The Act was passed by the Australian Parliament and is aimed at safeguarding the public by maintaining high safety standards in civil aviation.
Scope and Application
The Civil Aviation Safety Regulations 1998, under the Civil Aviation Act 1988, empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) to ensure the safety of air navigation. These directives apply to specific types of aircraft and aeronautical products, as outlined in regulation 39.001, and are considered legislative instruments under the Legislative Instruments Act 2003. This regulatory framework is designed to maintain the continuing airworthiness of aircraft registered in Australia, in line with international obligations under Annex 8 of the Convention on International Civil Aviation. The State of Registry, which in Australia is CASA, must ensure that each aircraft meets continuing airworthiness standards, and this includes implementing ADs issued by the relevant State of Design. For instance, when the United States Federal Aviation Administration (FAA) issues an AD for Boeing 737 series aircraft, CASA assesses the directive and, if deemed necessary, issues a corresponding Australian AD to mandate the required safety measures. This process reflects Australia’s commitment to international civil aviation standards and ensures the safety of aircraft operating within Australian airspace.
Key Provisions
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 together establish the framework for the issuance of airworthiness directives (ADs). Section 98 of the Civil Aviation Act 1988 empowers the Governor-General to make regulations for air navigation safety, while regulation 39.001 of the Civil Aviation Safety Regulations 1998 authorises the Civil Aviation Safety Authority (CASA) to issue ADs for specific types of aircraft or aeronautical products. These ADs are formal regulatory instruments, subject to disallowance under section 46A of the Acts Interpretation Act 1901, and are considered legislative instruments as per section 6 of the Legislative Instruments Act 2003.
Under the obligations set forth in the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998, CASA must assess any ADs issued by the State of Design and, if necessary, issue corresponding Australian ADs to ensure the continuing airworthiness of aircraft registered in Australia. This requirement is rooted in Annex 8 to the Convention on International Civil Aviation, which stipulates that the State of Design bears the responsibility for the continuing airworthiness of an aircraft type and must provide necessary information to the State of Registry. The State of Registry, in turn, must implement measures to maintain the airworthiness of individual aircraft.
Failure to comply with an AD can lead to significant consequences. Although the specific civil or criminal penalties are not detailed in the provided text, non-compliance generally results in regulatory enforcement actions, which could include fines or other sanctions. The seriousness of the penalties likely depends on the severity of the non-compliance and the potential risk posed to aviation safety.
The issuance of ADs, such as AD 2006-10-17 affecting Boeing 737 series aircraft by the United States Federal Aviation Administration (FAA), underscores the international coordination required to maintain airworthiness standards. As Australia’s national airworthiness authority, CASA must respond appropriately to foreign ADs by issuing corresponding Australian ADs, ensuring that all aircraft registered in Australia meet the necessary safety standards. This process highlights the importance of adhering to international conventions and the collaborative efforts among countries to uphold aviation safety.
