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 2006-07-04 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/B737/287 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, enacted by the Commonwealth Parliament, establishes the regulatory framework for ensuring the safety and efficiency of civil aviation in Australia. In line with this Act, the Civil Aviation Safety Regulations 1998 were introduced to provide detailed provisions for implementing the regulatory requirements. One significant aspect of these regulations is the ability to issue airworthiness directives (ADs) under regulation 39.001. These directives, as stipulated in subregulation 39.001(5), are considered legislative instruments under the Legislative Instruments Act 2003. The primary objective of ADs is to maintain the continuing airworthiness of aircraft, aligning with Australia's obligations under the Convention on International Civil Aviation. When a State of Design issues an AD for a type of aircraft registered in Australia, the Civil Aviation Safety Authority (CASA) is mandated to assess the information and, if necessary, issue an Australian AD to enforce the requirements. This process ensures that Australian aviation remains compliant with international standards and maintains safety and operational integrity.
Scope and Application
The Civil Aviation Safety Regulations 1998, specifically regulation 39.001, empowers the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for types of aircraft or aeronautical products, acting in accordance with section 98 of the Civil Aviation Act 1988. This authority is exercised under the overarching responsibility of the State of Design to ensure the continuing airworthiness of aircraft types, as outlined in Annex 8 to the Convention on International Civil Aviation. When an AD is issued by the State of Design, such as the United States Federal Aviation Administration (FAA) for Boeing 737 aircraft, CASA is mandated to assess and, if appropriate, issue corresponding Australian ADs. These ADs, which include AD/B737/287 in response to FAA's AD 2006-07-04, become binding upon their publication and are considered disallowable instruments under the Acts Interpretation Act 1901, and legislative instruments under the Legislative Instruments Act 2003. The application of these ADs is national in scope and applies to all relevant aircraft registered in Australia, with the State of Registry ensuring the compliance of individual aircraft with these safety directives.
Key Provisions
The Civil Aviation Act 1988, and more specifically the Civil Aviation Safety Regulations 1998, provide the framework for issuing airworthiness directives (ADs) under section 98 and regulation 39.001. The Civil Aviation Act 1988 empowers the Governor-General to make regulations for the safety of air navigation, and the Civil Aviation Safety Regulations 1998 allow the Civil Aviation Safety Authority (CASA) to issue ADs for specific aircraft or aeronautical products. These ADs serve as legislative instruments, as outlined in section 46A of the Acts Interpretation Act 1901 and section 6 of the Legislative Instruments Act 2003. The State of Design, which is responsible for the continuing airworthiness of an aircraft type, must provide necessary information to ensure compliance with international standards. This information is typically communicated through ADs, which are issued by most International Civil Aviation Organization (ICAO) Contracting States.
The obligations imposed by these provisions primarily fall on CASA, as Australia’s national airworthiness authority. CASA is required to assess any ADs issued by the State of Design and determine if they need to be adopted and enforced in Australia. For example, when the United States Federal Aviation Administration (FAA) issued AD 2006-07-04 for Boeing 737 aircraft, CASA assessed this directive and issued its own Australian AD/B737/287 to ensure compliance with international standards. This process underscores CASA's responsibility to ensure that aircraft registered in Australia meet the necessary safety and airworthiness standards.
There are significant consequences for non-compliance with ADs. Under the Civil Aviation Act 1988, failure to adhere to an AD can result in various penalties. These can include both civil and criminal sanctions, depending on the severity of the breach. The specific penalties are not detailed in the provided text, but generally, non-compliance can lead to fines, imprisonment, or both. Given the critical nature of airworthiness directives in ensuring public safety, penalties are often substantial to enforce compliance effectively.
In summary, the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 establish a robust framework for issuing and enforcing airworthiness directives. CASA’s role is central in assessing and adopting these directives to ensure that all aircraft registered in Australia meet the necessary safety standards. Failure to comply with these directives can result in serious civil and criminal penalties, highlighting the importance of adhering to these regulations.
