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 33/15 Amdt 1, affecting Beech 33 and 35-33 model aircraft in 1973. CASA has reviewed this AD and as a result has decided to cancel it. The cancellation will become effective on 10 April 2008. 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, 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 Parliament of Australia, was introduced to regulate the safety and efficiency of civil aviation in Australia. This legislation provides the framework for the oversight of air navigation safety, which is critical to the nation's aviation industry and public safety. Under the authority granted by the Act, the Civil Aviation Safety Regulations 1998 were subsequently introduced to provide more detailed rules and requirements for ensuring the airworthiness of aircraft and aeronautical products. One such regulation, 39.001, allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) that are enforceable by law. These ADs serve as a critical mechanism for addressing safety issues that may affect the continuing airworthiness of aircraft types registered in Australia. The policy objective underpinning these regulations is to ensure the highest standards of safety in civil aviation, aligning with international obligations under the Convention on International Civil Aviation.
Scope and Application
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 govern the issuance of airworthiness directives (ADs) in Australia, with the Civil Aviation Safety Authority (CASA) having the authority to issue these directives under regulation 39.001. These directives are legislative instruments that apply to specific kinds of aircraft or aeronautical products, aimed at ensuring the safety of air navigation. The Act and Regulations apply nationally, covering all aircraft registered in Australia and ensuring compliance with international standards as outlined in Annex 8 to the Convention on International Civil Aviation. The State of Design and the State of Registry have respective roles in maintaining the airworthiness of aircraft types and individual aircraft. CASA’s authority to issue ADs is exercised when necessary to address safety concerns, and these directives can be cancelled if the conditions that necessitated them no longer exist. In the case of AD/BEECH 33/15 Amdt 1, CASA decided to cancel the directive as the unsafe condition it was meant to address no longer exists, with the cancellation effective from 10 April 2008. This cancellation was made without public consultation due to its nature of reducing regulatory burden, and no replacement AD is required. The AD was issued by the Manager, Airframes in the Airworthiness Engineering Branch, on behalf of CASA, in accordance with the legislative provisions.
Key Provisions
The Civil Aviation Act 1988, under section 98, empowers the Governor-General to create regulations aimed at ensuring the safety of air navigation. One significant regulation, 39.001 of the Civil Aviation Safety Regulations 1998, authorises the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. An AD is a legislative instrument, as stipulated by subregulation 39.001(5) and section 46A of the Acts Interpretation Act 1901, and it is subject to disallowance under section 6 of the Legislative Instruments Act 2003.
These airworthiness directives are essential tools for maintaining the continuing airworthiness of aircraft, as outlined in Annex 8 to the Convention on International Civil Aviation. The State of Design, responsible for an aircraft type, must provide necessary information to ensure its airworthiness, which is then adopted by the State of Registry. CASA, as Australia's national airworthiness authority, evaluates information from the State of Design and, if necessary, issues Australian ADs to enforce the required safety measures. For example, CASA issued AD/BEECH 33/15 Amdt 1 in 1973, affecting Beech 33 and 35-33 model aircraft, which has since been cancelled due to the original unsafe condition no longer existing.
The obligations placed on parties by this legislation include the responsibility of the State of Design to provide information for continuing airworthiness and the duty of the State of Registry to develop or adopt requirements for maintaining the airworthiness of aircraft. CASA must review and, if necessary, issue Australian ADs based on the information provided by the State of Design. Furthermore, the Office of Best Practice Regulation has determined that ADs do not require a Regulatory Impact Statement, and in this instance, no consultation with the Australian public was necessary due to the reduction in regulatory burden.
The consequences of non-compliance with these provisions can be severe. Under the Civil Aviation Act 1988, failure to adhere to airworthiness directives can result in significant penalties. The maximum penalties for non-compliance with ADs are substantial, reflecting the critical importance of adhering to these safety measures. The specific penalties are detailed in the Act and may include fines or imprisonment, depending on the severity of the breach. The AD cancellation process, as exemplified by the cancellation of AD/BEECH 33/15 Amdt 1, is overseen by the Manager, Airframes in the Airworthiness Engineering Branch, on behalf of CASA, in accordance with subsection 84A(2) of the Act.
