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/PA-36/23 affecting Piper PA-36 series aircraft in 1991. CASA has reviewed this AD and as a result has decided to cancel it. The cancellation will become effective on 17 January 2008. No replacement AD is required, as the original unsafe condition has long ceased to exist.
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 was enacted to provide for the regulation of civil aviation in Australia, with a strong emphasis on safety. This legislation empowers the Governor-General to make regulations that are in the interests of the safety of air navigation. The Civil Aviation Safety Regulations 1998 further elaborate on these provisions, allowing the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. These ADs are essential tools for maintaining the continuing airworthiness of aircraft and ensuring compliance with international standards as set out in Annex 8 to the Convention on International Civil Aviation. The Civil Aviation Act 1988 thus addresses the need for a robust framework to manage and enforce aviation safety standards in Australia.
In accordance with the legislative process outlined in the Legislative Instruments Act 2003, ADs are considered legislative instruments that can be disallowable under the Acts Interpretation Act 1901. CASA, as the national airworthiness authority, has the responsibility to assess and, if necessary, issue Australian ADs when State of Design ADs are applicable to aircraft registered in Australia. This ensures that all stakeholders are adequately informed and compliant with safety requirements. The cancellation of AD/PA-36/23, effective from 17 January 2008, is an example of CASA’s commitment to maintaining accurate and relevant regulatory measures, reducing unnecessary regulatory burdens without the need for public consultation or a Regulatory Impact Statement.
Scope and Application
The Civil Aviation Act 1988, supplemented by the Civil Aviation Safety Regulations 1998, provides the framework for ensuring the safety of air navigation in Australia. Specifically, regulation 39.001 of these regulations allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for types of aircraft or aeronautical products. These ADs, which are legislative instruments under the Acts Interpretation Act 1901 and the Legislative Instruments Act 2003, are essential for maintaining the continuing airworthiness of aircraft as stipulated by Annex 8 to the Convention on International Civil Aviation. The State of Design, typically the manufacturer, has the primary responsibility for ensuring the airworthiness of an aircraft type, while the State of Registry, in Australia's case CASA, enforces these standards and issues ADs as necessary. In the specific instance of AD/PA-36/23 affecting Piper PA-36 series aircraft, CASA has decided to cancel the directive, effective from 17 January 2008, due to the cessation of the original unsafe condition, thereby reducing the regulatory burden without necessitating a replacement AD. The decision to cancel the AD was made in accordance with the legislative provisions and did not require public consultation or a Regulatory Impact Statement, as determined by the Office of Best Practice Regulation.
Key Provisions
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 outline the processes and responsibilities associated with airworthiness directives (ADs). Section 98 of the Act allows the Governor-General to enact regulations that ensure the safety of air navigation, while regulation 39.001 of the Regulations empowers the Civil Aviation Safety Authority (CASA) to issue ADs for specific types of aircraft or aeronautical products. These ADs are considered legislative instruments under the Legislative Instruments Act 2003. The ADs are crucial for maintaining the continuing airworthiness of aircraft, a responsibility that falls on both the State of Design and the State of Registry, as stipulated in Annex 8 to the Convention on International Civil Aviation.
The obligations imposed by these regulations require CASA to assess any ADs issued by the State of Design and to issue corresponding Australian ADs if necessary. This ensures that all aircraft registered in Australia comply with safety standards that have been internationally recognised. Specifically, when a State of Design issues an AD, CASA must evaluate the information and determine whether an Australian AD is needed to mandate the requirements of the State of Design. This systematic approach helps maintain a consistent level of safety across the Australian fleet.
Failure to comply with an AD can lead to significant consequences. Under the Civil Aviation Act 1988, non-compliance with an AD can be considered an offence. The maximum penalties for such offences can include fines and imprisonment, reflecting the serious nature of ensuring air safety. Additionally, operators who fail to comply with an AD may face suspension or revocation of their airworthiness certificates, which would effectively ground their aircraft until the required actions are taken. This dual approach of civil and criminal penalties ensures that there are strong deterrents against non-compliance with ADs.
