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 German LBA has issued AD 74-162 affecting Messerschmitt-Bolkow Blohm BO-105 model helicopters. Germany is the State of Design for this type. CASA has assessed this AD and has issued Australian AD/BO 105/18, which will become effective on 27 September 2007.
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, enacted by the Parliament of Australia, provides the legal framework for the regulation of civil aviation within Australia, with a primary focus on ensuring the safety of air navigation. In line with this objective, the Civil Aviation Safety Regulations 1998 empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products under regulation 39.001. These directives are legislative instruments that must comply with the Acts Interpretation Act 1901. The ADs serve to implement international standards and obligations, particularly under Annex 8 to the Convention on International Civil Aviation, which assigns the State of Design the responsibility for ensuring the continuing airworthiness of aircraft types. The State of Registry, such as CASA in Australia, must adopt the necessary measures to enforce these directives and maintain the airworthiness of individual aircraft registered within its jurisdiction. This legislative structure aims to harmonise national regulations with international standards, ensuring a consistent approach to aviation safety across borders.
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) for specified types of aircraft or aeronautical products. These ADs are legislative instruments, subject to disallowance under the Acts Interpretation Act 1901, and their issuance is mandated by Australia's obligations under the Convention on International Civil Aviation, particularly Annex 8, which delineates the responsibilities of the State of Design and the State of Registry concerning the continuing airworthiness of aircraft. CASA, as Australia’s national airworthiness authority, must ensure compliance with these international obligations by issuing corresponding ADs when required. For instance, in response to an AD issued by Germany’s Luftfahrt-Bundesamt (LBA) concerning Messerschmitt-Bolkow Blohm BO-105 model helicopters, CASA has issued Australian AD/BO 105/18, reflecting the international standard and ensuring that Australian-registered aircraft meet necessary safety requirements. This process does not involve public consultation as it is governed by international conventions and is issued directly in response to international directives. The issuance of such ADs is carried out by the Manager, Airframes in the Airworthiness Engineering Branch, on behalf of CASA, in accordance with the Act's provisions.
Key Provisions
The Civil Aviation Safety Regulations 1998, under section 39.001, grant the Civil Aviation Safety Authority (CASA) the authority to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. An AD is a legislative instrument, as defined under section 6 of the Legislative Instruments Act 2003 and is also considered a disallowable instrument under section 46A of the Acts Interpretation Act 1901. This means that ADs hold legal weight and must be adhered to by the relevant parties.
These ADs are essential for ensuring the continuing airworthiness of aircraft, a responsibility that falls on the State of Registry, as per Annex 8 to the Convention on International Civil Aviation. The State of Design, which is Germany in the case of the Messerschmitt-Bolkow Blohm BO-105 model helicopters, must provide necessary information to maintain airworthiness. CASA, as Australia's national airworthiness authority, must assess this information and, if deemed necessary, issue an Australian AD to enforce the requirements set by the State of Design. Such was the case with AD/BO 105/18, which was issued by CASA and will take effect on 27 September 2007.
The obligations imposed by the ADs are binding on the relevant parties, such as aircraft operators and manufacturers, requiring them to comply with the specified safety measures and maintenance requirements. Failure to comply with these directives can lead to severe consequences, including potential grounding of the aircraft, revocation of airworthiness certificates, and legal action against the non-compliant parties. These measures are in place to ensure that all aircraft meet the highest safety standards.
Breach of the ADs can result in civil or criminal penalties. For civil offences, penalties can include fines up to a maximum of $10,500 for individuals and $52,500 for bodies corporate, as stipulated under the Civil Aviation Act 1988. For criminal offences, penalties can be more severe, with potential fines of up to $210,000 for individuals and $1,050,000 for bodies corporate, along with possible imprisonment. These stringent penalties underscore the importance of adhering to ADs to maintain aviation safety standards.
