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 UK CAA has issued AD 005-01-2002 affecting BAe Jetstream 4100 model aircraft. The UK is the State of Design for this type. CASA has assessed this AD and has issued Australian AD/J4100/20, which will become effective on 20 February 2008.
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 Manager, Airframes in the Airworthiness Engineering Branch, on behalf of CASA, in accordance with subsection 84A (2) of the Act.
Overview
The Civil Aviation Act 1988 was enacted to govern civil aviation in Australia, ensuring the safety and efficiency of air navigation. One of the key mechanisms provided by this Act is the authority for the Governor-General to make regulations, including issuing airworthiness directives (ADs) as stipulated under section 98. The Civil Aviation Safety Regulations 1998 further empower the Civil Aviation Safety Authority (CASA) to issue ADs concerning aircraft types or aeronautical products under regulation 39.001. These ADs serve to maintain the continuing airworthiness of aircraft, aligning with the obligations of Australia under the Convention on International Civil Aviation. Given their legislative nature, ADs are disallowable instruments and are thus subject to parliamentary oversight. This framework ensures that CASA, as Australia’s national airworthiness authority, can effectively implement safety measures mandated by the relevant State of Design, such as the UK in the case of the BAe Jetstream 4100 model aircraft.
Scope and Application
The Civil Aviation Act 1988, through the Civil Aviation Safety Regulations 1998, empowers the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for certain types of aircraft or aeronautical products. These ADs are essential for ensuring the continuing airworthiness of aircraft and are mandated by the State of Registry in accordance with international obligations under the Convention on International Civil Aviation. The ADs are legislative instruments, subject to disallowance and review, and are issued in response to directives from the State of Design, such as the United Kingdom Civil Aviation Authority for the BAe Jetstream 4100 model aircraft. CASA, acting as Australia's national airworthiness authority, assesses and issues Australian ADs, which are legally binding for the aircraft registered in Australia. The process of issuing these ADs is streamlined and does not require public consultation or a Regulatory Impact Statement, reflecting the urgent and safety-critical nature of airworthiness directives. The authority to issue these directives is exercised by designated officials within CASA, ensuring that the regulations are implemented efficiently and effectively to maintain safety standards.
Key Provisions
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 provide the legislative framework for the issuance of airworthiness directives (ADs) in Australia. Section 98 of the Civil Aviation Act 1988 allows the Governor-General to make regulations necessary for the safety of air navigation, while regulation 39.001 of the Civil Aviation Safety Regulations 1998 specifically empowers the Civil Aviation Safety Authority (CASA) to issue ADs for certain types of aircraft or aeronautical products. It is important to note that these ADs are legislative instruments as per section 6 of the Legislative Instruments Act 2003 and can be disallowed under section 46A of the Acts Interpretation Act 1901.
Under these provisions, CASA has the authority to issue ADs that mandate specific requirements for ensuring the continuing airworthiness of aircraft. This is particularly pertinent when an AD is issued by the State of Design, as the State of Design is responsible for the continuing airworthiness of the aircraft type according to Annex 8 of the Convention on International Civil Aviation. In such cases, CASA must assess the AD from the State of Design and, if necessary, issue an Australian AD to enforce the requirements specified by the State of Design. For instance, the UK Civil Aviation Authority (CAA) issued AD 005-01-2002 affecting the BAe Jetstream 4100 model aircraft, and CASA responded by issuing Australian AD/J4100/20, which became effective on 20 February 2008.
Entities and parties governed by these regulations are required to adhere to the ADs issued by CASA. Specifically, aircraft operators and owners must comply with the ADs applicable to their aircraft, ensuring that any required modifications, inspections, or repairs are carried out within the specified timeframes. Failure to comply with an AD can result in serious safety implications and potentially render the aircraft unairworthy.
Breach of the requirements set out in an AD can lead to significant legal consequences. The Civil Aviation Act 1988 and associated regulations provide for both civil and criminal penalties for non-compliance. Civil penalties may include fines, and in severe cases, aircraft operators or owners could face criminal charges. The maximum penalties can vary depending on the nature and severity of the breach but are intended to ensure strict adherence to safety standards. For instance, operating an aircraft in contravention of an AD can result in substantial fines, and in cases of gross negligence, imprisonment may be imposed. These provisions underscore the importance of complying with ADs to maintain the highest standards of aviation safety.
