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 US FAA has issued AD 2006-23-14 affecting Air Tractor AT 600 model aircraft. The USA is the State of Design for this type. CASA has assessed this AD and has issued Australian AD/AT 600/6, which will become effective on 18 January 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 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, provides the legal framework for regulating civil aviation in Australia. Among its provisions, the Act empowers the Governor-General to issue regulations under section 98 to ensure the safety of air navigation. Complementing this, the Civil Aviation Safety Regulations 1998 allow the Civil Aviation Safety Authority (CASA) to issue airworthiness directives, which are legislative instruments subject to disallowance under the Acts Interpretation Act 1901 and the Legislative Instruments Act 2003. These directives are essential for maintaining the continuing airworthiness of aircraft, as per the obligations under the Convention on International Civil Aviation, particularly through Annex 8. CASA's role includes issuing Australian airworthiness directives in response to those issued by the aircraft's State of Design, thereby ensuring compliance with international safety standards and domestic regulations.
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 specific types of aircraft or aeronautical products, ensuring compliance with safety standards and continuing airworthiness as per international standards set by ICAO. This legislation applies to aircraft registered in Australia and is driven by Australia’s obligations under the Convention on International Civil Aviation. The State of Design, in this case, the USA, issues initial ADs, and CASA evaluates and, if necessary, issues corresponding Australian ADs to maintain the continuing airworthiness of these aircraft within Australia. The issuance of such directives does not require public consultation or a Regulatory Impact Statement, as they are governed by international safety protocols and are considered legislative instruments under the Legislative Instruments Act 2003. This regulatory framework ensures that all stakeholders, including aircraft operators and manufacturers, adhere to safety mandates that are both nationally and internationally recognised.
Key Provisions
The Civil Aviation Act 1988 (section 98) empowers the Governor-General to establish regulations for the safety of air navigation, and under regulation 39.001 of the Civil Aviation Safety Regulations 1998, the Civil Aviation Safety Authority (CASA) is authorised to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. Section 39.001(5) further clarifies that these ADs are considered disallowable instruments, thus establishing them as legislative instruments under section 6 of the Legislative Instruments Act 2003. This legislative framework is designed to ensure the ongoing airworthiness of aircraft, aligning with international standards set forth by the Convention on International Civil Aviation, particularly Annex 8, which delineates the responsibilities of the State of Design and the State of Registry in maintaining airworthiness.
Under the Civil Aviation Safety Regulations 1998, the State of Design has a primary responsibility to provide information that ensures the continuing airworthiness of an aircraft type. This information is often communicated through ADs, which are mandated by the relevant State of Design and must be assessed and, if necessary, adopted by the State of Registry. In Australia, CASA is tasked with this assessment and, if appropriate, issuing corresponding ADs for aircraft registered in Australia. For example, following the US Federal Aviation Administration’s (FAA) issuance of AD 2006-23-14 for Air Tractor AT 600 model aircraft, CASA assessed the directive and issued Australian AD/AT 600/6, which took effect on 18 January 2007. This process underscores the international cooperation and regulatory alignment necessary to maintain aviation safety standards.
The obligations imposed by the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 require CASA to diligently assess and, where necessary, implement ADs issued by the State of Design. The State of Registry, in this case CASA, must ensure that all aircraft registered within its jurisdiction comply with the continuing airworthiness requirements set out in these ADs. This involves a thorough evaluation of the ADs issued by the State of Design, ensuring they are appropriate for the Australian context and subsequently issuing corresponding ADs to mandate compliance among Australian operators. This process ensures that all aircraft operating in Australian airspace meet the necessary safety standards as dictated by international conventions and regulatory bodies.
Non-compliance with ADs can result in serious consequences. Under the Civil Aviation Act 1988, failure to adhere to an AD can be considered an offence. Such offences may lead to both civil and criminal penalties, depending on the severity and intent behind the non-compliance. For instance, operating an aircraft in violation of an AD may result in fines or other civil penalties, while more egregious cases may lead to criminal charges, including imprisonment. The specific penalties are outlined in the regulations and may vary based on the nature of the offence, but the overarching aim is to enforce strict compliance to uphold the highest safety standards in aviation.
