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/BEECH 50/25, affecting BEECH 50 model aircraft in 1973. CASA has reviewed this AD and as a result has decided to cancel it. The cancellation will become effective on 5 June 2008. No replacement AD is required as all affected aircraft would have been inspected, and, if necessary modified, long ago.
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, Airframes in the Airworthiness Engineering Branch, on behalf of CASA, in accordance with subsection 84A (2) of the Act.
Overview
The Civil Aviation Act 1988, enacted by the Australian Parliament, was designed to regulate civil aviation within Australia, focusing on ensuring the safety of air navigation. One significant aspect of this Act is the delegation of power to the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) under regulation 39.001 of the Civil Aviation Safety Regulations 1998. These directives are legislative instruments aimed at maintaining the airworthiness of aircraft and aeronautical products in line with international standards set forth by the International Civil Aviation Organization (ICAO). The problem this legislation addresses is the need for a robust framework to ensure that aircraft operating within Australian airspace meet the necessary safety standards, thereby protecting both passengers and the public. The objective is to harmonise Australia's aviation safety measures with global standards, ensuring that all aircraft are maintained to a high level of safety, which in turn protects the integrity of air navigation.
Scope and Application
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 provide the framework for the issuance of airworthiness directives (ADs) by the Civil Aviation Safety Authority (CASA) to ensure the safety of air navigation. Specifically, under regulation 39.001 of the Civil Aviation Safety Regulations 1998, CASA is empowered to issue ADs for particular kinds of aircraft or aeronautical products. These ADs are legislative instruments, subject to disallowance under section 46A of the Acts Interpretation Act 1901, and their creation follows the processes outlined in the Legislative Instruments Act 2003. The ADs mandate compliance with continuing airworthiness requirements, a responsibility that ultimately rests with the State of Registry of the aircraft, in accordance with Annex 8 to the Convention on International Civil Aviation. The ADs serve as a means for CASA to implement the requirements of the State of Design when they issue directives that affect aircraft registered in Australia. As the national airworthiness authority, CASA must assess and, where appropriate, issue Australian ADs to ensure that all aircraft in Australia meet the necessary safety standards. The AD/BEECH 50/25, which was issued by CASA in 1973 and subsequently cancelled, exemplifies the process by which CASA mandates airworthiness requirements for specific aircraft models. The decision to cancel AD/BEECH 50/25 was made based on the assessment that the affected aircraft had already undergone necessary inspections and modifications, thereby reducing the regulatory burden without compromising safety.
Key Provisions
The Civil Aviation Act 1988, supported by the Civil Aviation Safety Regulations 1998, provides the legal framework for the issuance of airworthiness directives (ADs) which are critical to ensuring the safety of air navigation. Section 98 of the Act allows the Governor-General to make regulations for air navigation safety, while regulation 39.001 of the Regulations empowers the Civil Aviation Safety Authority (CASA) to issue ADs for certain types of aircraft or aeronautical products. An AD is a legislative instrument that becomes effective under section 6 of the Legislative Instruments Act 2003, following the disallowable instrument process outlined in section 46A of the Acts Interpretation Act 1901.
These ADs are integral to the continuing airworthiness of aircraft, with the State of Design having the primary responsibility to provide necessary information to the States of Registry, in line with Annex 8 of the Convention on International Civil Aviation. The State of Registry, in this case CASA as Australia’s national airworthiness authority, must ensure that these directives are appropriately assessed and, if necessary, translated into Australian ADs that mandate specific requirements. For instance, CASA issued AD/BEECH 50/25 for BEECH 50 model aircraft in 1973, and has since decided to cancel it due to the aircraft having already undergone necessary inspections and modifications.
Entities governed by these regulations, primarily CASA and aircraft operators, bear significant obligations. CASA must carefully review and act on ADs issued by the State of Design, ensuring that they are appropriately assessed and, if necessary, translated into Australian ADs. Aircraft operators, on the other hand, must comply with all mandated ADs to maintain the airworthiness of their aircraft. Failure to comply with these directives can result in serious safety risks, which could lead to enforcement actions by CASA.
The Civil Aviation Safety Regulations 1998 also outline the consequences of non-compliance with ADs. While specific penalties are not detailed in the provided text, it is clear that breaches of airworthiness directives can lead to civil or criminal penalties. These could include fines, suspension of airworthiness certificates, or even criminal charges in cases of gross negligence or deliberate non-compliance. The exact penalties would depend on the severity of the breach and would be determined in accordance with other relevant laws and regulations.
