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 33/26, affecting Beech 33 and 35-33 model aircraft in 1976. 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 was enacted to provide a comprehensive legislative framework for civil aviation in Australia, ensuring the safety and efficiency of air navigation. This Act empowers the Governor-General to make regulations necessary for the safety of air navigation, which includes the issuance of airworthiness directives by the Civil Aviation Safety Authority (CASA). These directives are a critical tool for maintaining the continuing airworthiness of aircraft, aligning with international standards set by the International Civil Aviation Organization (ICAO). The Civil Aviation Safety Regulations 1998 further detail the regulatory process, including the authority for CASA to issue airworthiness directives for specific aircraft types and aeronautical products. The policy objective underpinning these legislative measures is to ensure that aircraft on the Australian register meet stringent safety standards, thereby protecting public safety and fostering confidence in the civil aviation sector.
Scope and Application
The Civil Aviation Act 1988, through regulation 39.001 of the Civil Aviation Safety Regulations 1998, grants the Civil Aviation Safety Authority (CASA) the authority to issue airworthiness directives (ADs) concerning specific types of aircraft or aeronautical products, in the interests of ensuring the safety of air navigation. These ADs, which are legislative instruments under the Legislative Instruments Act 2003, are typically issued in response to continuing airworthiness information from the State of Design and mandate requirements for maintaining airworthiness, as per Annex 8 to the Convention on International Civil Aviation. In Australia, the State of Registry, which is CASA, is responsible for ensuring the continuing airworthiness of registered aircraft. The authority to issue and cancel ADs is exercised by CASA, with the specific example of AD/BEECH 33/26, affecting Beech 33 and 35-33 model aircraft, being cancelled due to the original unsafe condition no longer existing. The cancellation of such ADs reduces regulatory burden and does not necessitate public consultation or a Regulatory Impact Statement. The AD cancellation is made by the Manager, Airframes in the Airworthiness Engineering Branch, on behalf of CASA, in accordance with the Act.
Key Provisions
The Civil Aviation Act 1988, particularly section 98, provides the authority for the Governor-General to make regulations concerning air navigation safety. Under these provisions, the Civil Aviation Safety Regulations 1998, specifically regulation 39.001, empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for certain types of aircraft or aeronautical products. An AD is a disallowable instrument under section 46A of the Acts Interpretation Act 1901 and is classified as a legislative instrument in accordance with section 6 of the Legislative Instruments Act 2003. These directives are essential for ensuring the continuing airworthiness of aircraft types, as stipulated in Annex 8 of the Convention on International Civil Aviation.
Under the Civil Aviation Safety Regulations 1998, the State of Design, which is responsible for the design of an aircraft, has an overarching obligation to provide all necessary information to maintain the airworthiness of an aircraft type. The State of Registry, where the aircraft is registered, must develop or adopt requirements to ensure the continuing airworthiness of aircraft within its jurisdiction. Consequently, when a State of Design issues an AD, CASA, as Australia’s national airworthiness authority, must review the information and, if appropriate, issue a corresponding Australian AD. This ensures that Australian-registered aircraft comply with the necessary safety requirements as dictated by the State of Design.
There are no specific obligations or requirements placed on the Australian public for the issuance or compliance with ADs. However, CASA's duty to review and potentially issue Australian ADs ensures that all stakeholders adhere to the necessary safety standards. For instance, CASA issued AD/BEECH 33/26 for Beech 33 and 35-33 model aircraft in 1976, which has now been reviewed and cancelled, effective from 10 April 2008, due to the resolution of the original unsafe condition. This cancellation, which does not require public consultation as it reduces regulatory burden, was determined by the Office of Best Practice Regulation to not necessitate a Regulatory Impact Statement.
Regarding the consequences for non-compliance, the Civil Aviation Act 1988 does not explicitly outline specific offences or penalties related to the breach of ADs. However, non-compliance with ADs can result in significant legal repercussions under other sections of the Act, including potential civil or criminal penalties. The exact penalties would depend on the nature and severity of the non-compliance, but they could include substantial fines or even imprisonment. CASA enforces these requirements rigorously to uphold the highest safety standards in civil aviation.
