CIVIL AVIATION ACT 1988
CIVIL AVIATION 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 US FAA has issued AD 2003-05-10R1 affecting General Electric CF34 turbofan engines. US is the State of Design for this type of engine. CASA has assessed this AD and has issued Australian AD/CF34/8 Amendment 1, which will become effective 14 April 2005 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 Regulatory Review has determined that ADs do not require a Regulatory Impact Statement.
The AD has been made by the Section Head - Systems, Airworthiness Standards Branch, Standards Division, 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. It provides a framework for the issuance of airworthiness directives (ADs) by the Civil Aviation Safety Authority (CASA), mandated by regulation 39.001 of the Civil Aviation Safety Regulations 1998. These directives serve as legislative instruments under the Acts Interpretation Act 1901 and are integral to maintaining the continuing airworthiness of aircraft as per Annex 8 of the Convention on International Civil Aviation. The Civil Aviation Act 1988 empowers the Governor-General to make regulations in the interests of safety, with CASA acting on behalf of the Australian government to implement these regulations. The policy objective behind the Act is to ensure the safety and efficiency of civil aviation in Australia, aligning with international standards and obligations.
Scope and Application
The Civil Aviation Act 1988, in conjunction with the Civil Aviation Safety Regulations 1998, empowers the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) concerning specific types of aircraft or aeronautical products. This regulatory mechanism is designed to ensure the safety of air navigation in Australia and aligns with Australia’s obligations under the Convention on International Civil Aviation, particularly Annex 8, which mandates that the State of Design is responsible for the continuing airworthiness of an aircraft type. In this context, the State of Registry, which for Australia is CASA, must adopt and enforce ADs issued by the State of Design. For instance, following the US Federal Aviation Administration’s issuance of AD 2003-05-10R1 for General Electric CF34 turbofan engines, CASA assessed the directive and issued Australian AD/CF34/8 Amendment 1, effective from 14 April 2005. This AD replaces the previous directive and is a legislative instrument under the Legislative Instruments Act 2003, thus requiring no public consultation or Regulatory Impact Statement. The AD applies to all aircraft registered in Australia that use the specified engines, ensuring compliance with international safety standards and maintaining the continuing airworthiness of these aircraft within Australia’s jurisdiction.
Key Provisions
The main operative sections of the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 provide a framework for the issuance of airworthiness directives (ADs) (section 98 and regulation 39.001). These regulations empower the Civil Aviation Safety Authority (CASA) to issue ADs for specific types of aircraft or aeronautical products, which are considered legislative instruments under the Legislative Instruments Act 2003 (section 6). Under regulation 39.001(5), ADs are disallowable instruments under section 46A of the Acts Interpretation Act 1901, indicating that they require parliamentary oversight. Furthermore, in line with Annex 8 of the Convention on International Civil Aviation, the State of Design holds the primary responsibility for the continuing airworthiness of aircraft types and must share necessary information with States of Registry. The State of Registry, in this case CASA, must then assess this information and, if necessary, issue an Australian AD to ensure compliance with the State of Design’s requirements.
The Civil Aviation Safety Regulations 1998 impose several obligations on the entities governed by the Act. Firstly, the State of Design must provide critical information regarding the airworthiness of aircraft types to ensure their safe operation, as stipulated by Annex 8 of the Convention on International Civil Aviation. Secondly, the State of Registry, such as CASA, must develop or adopt appropriate requirements to guarantee the continuing airworthiness of aircraft. This includes assessing information provided by the State of Design and issuing ADs as necessary. CASA must ensure that all ADs issued are in accordance with the requirements set out in the Civil Aviation Safety Regulations 1998 and that they are consistent with the obligations under international conventions. Moreover, the State of Registry must ensure that aircraft registered within its jurisdiction comply with all ADs issued by CASA.
Failure to comply with ADs can result in severe civil and criminal consequences. Under the Civil Aviation Act 1988, any person who contravenes an AD may be subject to enforcement action by CASA. Civil penalties for non-compliance can include fines up to the statutory maximum, as well as potential criminal charges for serious violations. The exact penalties depend on the severity of the breach and the discretion of the court. Additionally, operators who fail to comply with ADs may face operational restrictions, such as grounding of affected aircraft, until the required actions are taken. CASA has the authority to take legal action against non-compliant operators, which could lead to significant financial penalties and reputational damage.
