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 Italian authority (ENAC) has issued AD 2002-450 affecting Agusta AB412 model helicopters. Italy is the State of Design for this type. CASA has assessed this AD and has issued Australian AD/BELL 412/50, which will become effective on 16 March 2006.
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, establishes the framework for civil aviation safety in Australia. This Act empowers the Governor-General to create regulations aimed at ensuring the safety of air navigation. One such regulation, outlined in the Civil Aviation Safety Regulations 1998, permits the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. These ADs, which are legislative instruments subject to disallowance, play a crucial role in maintaining the continuing airworthiness of aircraft, in alignment with international standards set by the International Civil Aviation Organization (ICAO).
The ADs are issued in response to safety concerns identified by the State of Design, with CASA, as Australia’s national airworthiness authority, assessing and, if necessary, implementing these directives to ensure compliance with international obligations. This legislative mechanism underscores Australia's commitment to international safety standards while allowing CASA to effectively manage and respond to safety issues related to aircraft registered in Australia.
Scope and Application
The Civil Aviation Safety Regulations 1998 under the Civil Aviation Act 1988 establish a regulatory framework for ensuring the safety of air navigation in Australia. Specifically, regulation 39.001 authorises the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) concerning particular types of aircraft or aeronautical products. These directives are legislative instruments, subject to disallowance and review processes. The scope of the ADs extends to mandating requirements for the continuing airworthiness of aircraft registered in Australia, aligning with international standards set forth by the International Civil Aviation Organization (ICAO). This legislative action applies to aircraft manufacturers, operators, and other entities involved in the aviation industry within Australia, ensuring compliance with safety standards. While ADs are issued in response to international obligations and specific safety concerns identified by the State of Design, they do not typically require public consultation or a Regulatory Impact Statement, as they are direct responses to identified safety issues.
Key Provisions
The Civil Aviation Act 1988 allows the Governor-General to make regulations under section 98, with the aim of ensuring the safety of air navigation. Regulation 39.001 of 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. According to subregulation 39.001(5), an AD is considered a disallowable instrument under section 46A of the Acts Interpretation Act 1901, and therefore, it is a legislative instrument under section 6 of the Legislative Instruments Act 2003.
This legislative framework is in line with Annex 8 of the Convention on International Civil Aviation, which assigns the State of Design responsibility for the ongoing airworthiness of an aircraft type, including the provision of necessary information to ensure the continuing airworthiness of the aircraft type to the appropriate States of Registry. The State of Registry is, in turn, responsible for the continuing airworthiness of individual aircraft. When the State of Design issues an AD for a type of aircraft registered in Australia, CASA must assess this information and, if appropriate, issue an Australian AD to enforce the State of Design's requirements.
In the case of the Italian authority (ENAC) issuing AD 2002-450 affecting Agusta AB412 model helicopters, Italy is the State of Design. CASA has assessed this AD and issued Australian AD/BELL 412/50, which will take effect from 16 March 2006. Given that this AD is issued due to Australia’s obligations under the Convention on International Civil Aviation and in response to an AD raised by the State of Design, no consultation of the Australian public has occurred regarding 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.
Entities and individuals governed by the AD must comply with the requirements set out in the AD, which may include mandatory inspections, maintenance, and modifications to aircraft or aeronautical products. Failure to comply with the AD can result in serious safety risks and may lead to enforcement actions by CASA. Penalties for non-compliance with ADs can include fines, suspension or revocation of airworthiness certificates, and other administrative or legal actions. The specific penalties depend on the severity of the non-compliance and the discretion of CASA in enforcing the AD. It is critical for all stakeholders to adhere to the AD to ensure the safety and airworthiness of the affected aircraft or aeronautical products.
