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 European Aviation Safety Authority (EASA) has issued AD 2007-0305 affecting British Aerospace BAe 146 and AVRO 146-RJ model aircraft. EASA acts on behalf of The United Kingdom, the State of Design for these types. CASA has assessed this AD and has issued Australian AD/BAe 146/71, Amendment 3, which will become effective on 11 January 2008. This AD cancels and replaces the previous issue.
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 Acting 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 regulate civil aviation in Australia, ensuring the safety and efficiency of air navigation. The Act provides the framework for the creation of regulations, one of which is the Civil Aviation Safety Regulations 1998. These regulations empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) that mandate safety requirements for aircraft and aeronautical products. The ADs serve as a key mechanism to maintain the continuing airworthiness of aircraft, aligning with international standards set by the International Civil Aviation Organization (ICAO). The Civil Aviation Act 1988 thus addresses the need for a cohesive and legally binding approach to civil aviation safety, ensuring compliance with both national and international regulations. The authority to issue ADs is derived from section 98 of the Act, with CASA acting under the regulatory oversight provided by the Act and the Regulations.
Scope and Application
The Civil Aviation Act 1988, supported by the Civil Aviation Safety Regulations 1998, provides a comprehensive framework for ensuring the safety of air navigation in Australia, including the issuance of airworthiness directives (ADs). Under this Act, the Civil Aviation Safety Authority (CASA) is authorised to issue ADs for specific kinds of aircraft or aeronautical products, which are designed to mandate safety measures and ensure the continuing airworthiness of aircraft registered in Australia. These ADs are legislative instruments and are made in accordance with international standards, such as Annex 8 to the Convention on International Civil Aviation, which assigns responsibilities to the State of Design and the State of Registry for aircraft airworthiness. Specifically, the State of Design, such as the United Kingdom in the case of the British Aerospace BAe 146 and AVRO 146-RJ model aircraft, issues ADs that CASA must assess and, if necessary, implement as Australian ADs. This process ensures compliance with international obligations and maintains safety standards within Australia's aviation sector. Notably, ADs are issued without public consultation due to their alignment with international agreements and their technical nature, and they do not require a Regulatory Impact Statement as determined by the Office of Best Practice Regulation.
Key Provisions
The Civil Aviation Safety Regulations 1998, particularly regulation 39.001, empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) concerning specific types of aircraft or aeronautical products. These ADs are a formal mechanism to ensure the continuing airworthiness of aircraft, as per international standards outlined in Annex 8 to the Convention on International Civil Aviation. When CASA issues such directives, they are considered legislative instruments under the Legislative Instruments Act 2003, and thus, subject to disallowance provisions under the Acts Interpretation Act 1901. This means that ADs carry the same legal weight as any other legislative instrument, although they are issued in response to international obligations and assessments of foreign ADs.
The obligations placed on parties governed by these regulations are substantial. For example, the State of Design, which in this case is the United Kingdom for the BAe 146 and AVRO 146-RJ models, is responsible for ensuring the continuing airworthiness of the aircraft type and must provide necessary information to other States of Registry. The State of Registry, here represented by CASA, must then assess this information and, if necessary, issue their own ADs to mandate the requirements set by the State of Design. This collaborative approach ensures that all parties involved adhere to the highest safety standards. Moreover, the regulations require CASA to carefully evaluate the foreign ADs and decide whether they need to be implemented in Australia, maintaining a consistent level of safety across the aviation industry.
Non-compliance with airworthiness directives can lead to significant legal consequences. Under the Civil Aviation Act 1988, failure to comply with an AD can result in civil or criminal penalties. These penalties can include fines or imprisonment, depending on the severity of the breach and the impact on aviation safety. The specific maximum penalties are not detailed in the provided text, but they are typically outlined in the Act or in other related legislation. The overarching aim of these penalties is to enforce compliance and deter any actions that could compromise the safety of air navigation.
Additionally, ADs issued by CASA are exempt from certain regulatory requirements, such as public consultation and the need for a Regulatory Impact Statement, as determined by the Office of Best Practice Regulation. This exemption is based on the understanding that ADs are issued to meet international obligations and to ensure the immediate implementation of necessary safety measures. The AD in question, AD/BAe 146/71, Amendment 3, was issued by the Acting Manager, Airframes in the Airworthiness Engineering Branch, on behalf of CASA, and follows the formal legislative process outlined in the Act. This highlights the structured and authoritative manner in which ADs are issued and enforced within Australia's aviation regulatory framework.
