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.
CASA issued AD/LA-4/8 affecting Consolidated Aeronautics, Colonial and LA-4 series aeroplanes in 1973. CASA has reviewed this AD and as a result has decided to cancel it. The cancellation will become effective on 22 October 2009. No replacement AD is required, as the original unsafe condition no longer exists.
No consultation with the Australian public has taken place on this AD cancellation, because the cancellation results in a reduction of the regulatory burden. The Office of Best Practice Regulation has determined that ADs do not require a Regulatory Impact Statement.
The AD has been made by the Manager, New Technology and Regulatory Trends of in the Standards Development and Future Technology Division, on behalf of CASA, in accordance with subsection 84A (2) of the Act.
Overview
The Civil Aviation Act 1988 was enacted to provide a comprehensive legislative framework for the regulation of civil aviation in Australia, aiming to ensure the safety and efficiency of air navigation. The Act grants the Governor-General the authority to create regulations under section 98, which are instrumental in maintaining air navigation safety. In line with this, the Civil Aviation Safety Regulations 1998 empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products, as stipulated in regulation 39.001. These ADs, which are considered legislative instruments under the Legislative Instruments Act 2003, play a crucial role in continuing the airworthiness of aircraft types, with the State of Design and the State of Registry sharing responsibilities as outlined in Annex 8 to the Convention on International Civil Aviation. In this context, CASA issued AD/LA-4/8 in 1973 for Consolidated Aeronautics, Colonial, and LA-4 series aeroplanes, but has since decided to cancel it due to the resolution of the original unsafe condition, effective from 22 October 2009.
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) that are crucial for ensuring the safety of air navigation. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 specifically authorises CASA to issue such directives for types of aircraft or aeronautical products. These ADs serve as a legislative instrument under the Legislative Instruments Act 2003 and are designed to maintain the continuing airworthiness of aircraft, aligning with the obligations under Annex 8 to the Convention on International Civil Aviation. The responsibility for the continuing airworthiness of an aircraft type lies with the State of Design, while the State of Registry is tasked with implementing the necessary requirements to ensure safety. CASA, as Australia’s national airworthiness authority, plays a pivotal role in assessing the information provided by the State of Design and issuing corresponding ADs to mandate compliance with safety standards. The cancellation of an AD, such as AD/LA-4/8 affecting Consolidated Aeronautics, Colonial and LA-4 series aeroplanes, is effective without the need for public consultation or a Regulatory Impact Statement, provided that it results in a reduction of regulatory burden and the unsafe condition no longer exists.
Key Provisions
The Civil Aviation Safety Regulations 1998, under section 39.001, provide that the Civil Aviation Safety Authority (CASA) has the authority to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. This is to ensure the safety of air navigation as per section 98 of the Civil Aviation Act 1988. These ADs serve as critical tools for maintaining the continuing airworthiness of aircraft, in accordance with Annex 8 to the Convention on International Civil Aviation. Specifically, the State of Design of an aircraft holds the primary responsibility for ensuring that the aircraft type remains airworthy, and must supply any necessary information to the State of Registry, which is Australia in this context.
CASA, as the national airworthiness authority, must review any ADs issued by the State of Design and, if necessary, issue corresponding Australian ADs. These directives are legislative instruments, as stipulated in section 46A of the Acts Interpretation Act 1901 and section 6 of the Legislative Instruments Act 2003. The obligations placed on CASA include assessing the information provided by the State of Design and determining whether an Australian AD is needed to enforce the necessary safety requirements. The AD/LA-4/8 issued in 1973 concerning Consolidated Aeronautics, Colonial, and LA-4 series aeroplanes is an example of such an action, although it has now been cancelled.
The cancellation of AD/LA-4/8, effective from 22 October 2009, is a result of the unsafe condition addressed by the original AD no longer existing. This cancellation reduces the regulatory burden and, as such, did not require public consultation. Additionally, the Office of Best Practice Regulation has determined that ADs do not necessitate a Regulatory Impact Statement. The Manager, New Technology and Regulatory Trends from CASA's Standards Development and Future Technology Division made this AD cancellation in accordance with subsection 84A(2) of the Act.
In terms of consequences for non-compliance, while the specific offences and penalties related to ADs are not detailed in the provided text, it is clear that failure to comply with CASA's airworthiness directives can result in serious safety risks. These risks could lead to enforcement actions, which might include fines, penalties, or other regulatory measures as prescribed by the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998.
