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.
The Civil Aviation Safety Authority or its predecessors issued AD/BN-2/26 affecting Pilatus Britten-Norman BN-2A model aeroplanes. CASA has assessed this AD and as a result has cancelled Australian AD/BN-2/26. The cancellation will become effective on 18 December 2008. No replacement AD is required, as the unsafe condition no longer exists.
As this AD has been cancelled because of Australia’s obligations under the Convention on International Civil Aviation, no consultation with the Australian public has taken place on this AD cancellation. 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, Airframe and Structures, in the Airworthiness Engineering Group, on behalf of CASA, in accordance with subsection 84A (2) of the Act.
Overview
The Civil Aviation Act 1988 was enacted to regulate civil aviation and ensure the safety of air navigation in Australia. Under this Act, the Governor-General has the authority to make regulations for the purposes of the Act, particularly with regard to the safety of air navigation. One such regulation, 39.001 of the Civil Aviation Safety Regulations 1998, allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. These directives are instrumental in maintaining the continuing airworthiness of aircraft as mandated by Annex 8 to the Convention on International Civil Aviation, which places the responsibility on the State of Design to provide necessary information to the States of Registry. The Civil Aviation Safety Authority, acting as Australia’s national airworthiness authority, must assess this information and, if necessary, issue an Australian AD to enforce the requirements of the State of Design. In the case of AD/BN-2/26 affecting Pilatus Britten-Norman BN-2A model aeroplanes, CASA has cancelled the directive as the unsafe condition it was addressing no longer exists, reflecting Australia's commitment to international safety standards.
Scope and Application
The Civil Aviation Act 1988, along with the Civil Aviation Safety Regulations 1998, provides the framework under which airworthiness directives (ADs) are issued and managed in Australia. The Act empowers the Governor-General to create regulations that ensure the safety of air navigation, and regulation 39.001 specifically allows the Civil Aviation Safety Authority (CASA) to issue ADs for particular types of aircraft or aeronautical products. These ADs are considered legislative instruments under the Legislative Instruments Act 2003 and are a critical component of ensuring the continuing airworthiness of aircraft as stipulated by Annex 8 to the Convention on International Civil Aviation. The State of Design holds primary responsibility for the airworthiness of aircraft types, while the State of Registry, in this case CASA, must enforce these requirements domestically. The issuance and cancellation of such directives are governed by international standards and domestic regulatory processes, ensuring that any changes, such as the cancellation of AD/BN-2/26 for Pilatus Britten-Norman BN-2A model aeroplanes, align with international obligations and safety standards.
Key Provisions
The Civil Aviation Act 1988, as supported by the Civil Aviation Safety Regulations 1998, provides the framework within which airworthiness directives (ADs) are issued to ensure the safety of air navigation. Under section 98 of the Act, the Governor-General has the authority to make regulations necessary for air safety, and regulation 39.001 specifically empowers the Civil Aviation Safety Authority (CASA) to issue ADs for certain types of aircraft or aeronautical products. These ADs serve as legislative instruments that are subject to disallowance under section 46A of the Acts Interpretation Act 1901 and are regulated by the Legislative Instruments Act 2003.
The obligations imposed by the Act and the Regulations are primarily on CASA, as the national airworthiness authority. CASA is mandated to assess any ADs issued by the State of Design and, if deemed appropriate, issue corresponding Australian ADs to mandate the requirements for aircraft registered in Australia. This includes ensuring that Australian ADs align with the continuing airworthiness standards set forth in Annex 8 to the Convention on International Civil Aviation. Furthermore, the State of Registry is responsible for the continuing airworthiness of individual aircraft, requiring it to develop or adopt necessary requirements to maintain airworthiness.
Breaches of the obligations under the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 can result in both civil and criminal consequences. Although specific offences and penalties are not detailed in the provided text, it is known that violations of airworthiness regulations can lead to significant consequences, including fines and imprisonment, depending on the severity of the breach. The exact penalties would be determined by relevant courts based on the specific circumstances of the violation.
The provided information does not mention any specific offences, penalties, or civil/criminal consequences for the cancellation of AD/BN-2/26. However, it is clear that the process of issuing, assessing, and cancelling ADs is governed by stringent regulatory frameworks designed to ensure that aircraft remain airworthy and safe for operation. The absence of a requirement for a Regulatory Impact Statement and public consultation, as determined by the Office of Best Practice Regulation, indicates the specific nature of ADs and their regulatory treatment. The cancellation of AD/BN-2/26 due to the resolution of the unsafe condition demonstrates CASA’s proactive approach to maintaining air safety standards.
