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 2006-0095 affecting Eurocopter AS 350 Ecureuil model helicopters. EASA acts on behalf of France, the State of Design for this type. CASA has assessed this AD and has issued Australian AD/ECUREUIL/107, Amendment 1, which will become effective on 31 August 2006. 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 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 was enacted to provide a legislative framework for the regulation of civil aviation in Australia, with a strong emphasis on safety. This Act empowers the Governor-General to make regulations for the safety of air navigation, including the issuance of airworthiness directives (ADs) which are critical for ensuring that aircraft remain airworthy throughout their operational lives. The Civil Aviation Safety Regulations 1998 further elaborate on the process for issuing ADs, which are legislative instruments subject to disallowance. The Civil Aviation (Airworthiness Directives) Instrument 2006 (F2006L02480) was introduced to address the need for Australia to align its regulatory framework with international standards and to ensure compliance with obligations under the Convention on International Civil Aviation, particularly concerning the continuing airworthiness of aircraft. This particular AD, issued by the Civil Aviation Safety Authority (CASA) on behalf of the Commonwealth, responds to an AD issued by the European Aviation Safety Authority (EASA) regarding the Eurocopter AS 350 Ecureuil model helicopters. Given the international nature and obligations driving this directive, no public consultation was deemed necessary, and it was determined that a Regulatory Impact Statement was not required.
Scope and Application
The Civil Aviation Act 1988, as supplemented by the Civil Aviation Safety Regulations 1998, provides the framework for the issuance of airworthiness directives (ADs) by the Civil Aviation Safety Authority (CASA). Specifically, regulation 39.001 of the Civil Aviation Safety Regulations 1998 empowers CASA to issue ADs for certain types of aircraft or aeronautical products, which are legislative instruments under the Legislative Instruments Act 2003. This legislation applies to entities and individuals involved in the operation and maintenance of aircraft registered in Australia, ensuring they comply with safety standards set forth by the State of Registry, which in this context is CASA. The geographic scope of this legislation is national, as it pertains to aircraft registered within Australia, and it aligns with international obligations under the Convention on International Civil Aviation. Notably, the issuance of ADs is driven by international agreements, such as Annex 8, and does not typically require consultation with the Australian public, nor does it necessitate a Regulatory Impact Statement. Any exclusions or exemptions are not specified in the provided text, but generally, ADs apply to all relevant aircraft unless otherwise specified.
Key Provisions
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 outline the framework for ensuring the safety of air navigation through various mechanisms, including the issuance of airworthiness directives (ADs) by the Civil Aviation Safety Authority (CASA). According to section 98 of the Civil Aviation Act 1988, the Governor-General is empowered to make regulations for the Act’s purposes, and section 39.001 of the Civil Aviation Safety Regulations 1998 specifically authorises CASA to issue ADs for kinds of aircraft or aeronautical products. An AD, as defined under subregulation 39.001(5), is a disallowable instrument under section 46A of the Acts Interpretation Act 1901 and thus constitutes a legislative instrument. These directives are essential tools for maintaining the continuing airworthiness of aircraft, a responsibility mandated by Annex 8 to the Convention on International Civil Aviation.
The obligations imposed by these regulations on the parties involved, particularly CASA and the States of Design and Registry, are significant. The State of Design has the overarching responsibility for ensuring the continuing airworthiness of an aircraft type, including providing necessary information to the States of Registry. The State of Registry, in turn, is tasked with developing or adopting requirements to ensure that individual aircraft remain airworthy. When a State of Design issues an AD, the corresponding State of Registry must evaluate this information and, if appropriate, issue its own AD to enforce the requirements set by the State of Design. In Australia, CASA, as the national airworthiness authority, performs this function. For example, in response to EASA’s AD 2006-0095 concerning Eurocopter AS 350 Ecureuil model helicopters, CASA issued Australian AD/ECUREUIL/107, Amendment 1, effective from 31 August 2006.
Failure to comply with ADs can result in serious consequences, both civil and criminal. The Civil Aviation Safety Regulations 1998 do not explicitly detail specific penalties for non-compliance with ADs, but non-compliance with airworthiness regulations generally can lead to severe sanctions. These may include fines, imprisonment, or both, depending on the severity of the breach and the impact on aviation safety. The precise penalties would be determined in the context of a court proceeding under the relevant sections of the Civil Aviation Act 1988 or other applicable laws. Moreover, non-compliance with an AD can result in the grounding of affected aircraft, which can have significant operational and financial implications for operators.
