AD/CESSNA 500/8 - Static System Drainage - Inspection - CANCELLED

Overview

The Civil Aviation Act 1988 was enacted to provide for the safety of air navigation in Australia, ensuring that civil aviation operates in a safe and efficient manner. Under the Act, the Governor-General is empowered to make regulations for the purposes of the Act and in the interests of the safety of air navigation. This includes the issuance of airworthiness directives (ADs) through the Civil Aviation Safety Regulations 1998, which allow the Civil Aviation Safety Authority (CASA) to mandate safety measures for certain types of aircraft or aeronautical products. In line with international standards set forth by the Convention on International Civil Aviation, the State of Design is responsible for the continuing airworthiness of an aircraft type, while the State of Registry is responsible for the individual aircraft. The AD/CESSNA 500/8, issued by CASA, was cancelled in recognition of Australia's obligations under the Convention, and no further consultation or regulatory impact statement was required for this cancellation as the unsafe condition addressed by the AD no longer exists.

Scope and Application

The Civil Aviation Act 1988, in conjunction with the Civil Aviation Safety Regulations 1998, establishes the framework under which airworthiness directives (ADs) can be issued, managed, and enforced within Australia. This legislation applies to entities such as aircraft operators, manufacturers, and maintenance providers, as well as individual aircraft and aeronautical products, aiming to ensure the safety of air navigation. The geographic reach of the Act extends across the Commonwealth, with ADs being applicable to all aircraft registered in Australia, regardless of the location of their manufacture or operation within the country. However, the Act also aligns with international obligations under the Convention on International Civil Aviation, particularly through Annex 8, which mandates that States of Design and States of Registry collaborate to maintain airworthiness standards. Although the Act provides a comprehensive structure for issuing and enforcing ADs, specific details and exceptions are often elaborated through subordinate instruments, which may extend or restrict the application of the primary legislation. The Civil Aviation Safety Authority (CASA) plays a pivotal role in this regulatory framework, with the authority to issue ADs and to cancel them when the underlying safety concerns are resolved. The legislative process for ADs, including their disallowance and review, is further governed by the Acts Interpretation Act 1901 and the Legislative Instruments Act 2003, ensuring that these directives are crafted and implemented with due regard to legislative protocols and public safety imperatives.

Key Provisions

The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 are the primary pieces of legislation governing civil aviation in Australia. Under section 98 of the Civil Aviation Act 1988, the Governor-General has the authority to make regulations for the safety of air navigation, and regulation 39.001 of the Civil Aviation Safety Regulations 1998 empowers the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific kinds of aircraft or aeronautical products. These ADs are considered legislative instruments under section 6 of the Legislative Instruments Act 2003, and they serve as a common form of continuing airworthiness information, as stipulated by Annex 8 to the Convention on International Civil Aviation. The obligations under these regulations require the State of Design to bear overall responsibility for the continuing airworthiness of an aircraft type and to provide necessary information to the State of Registry, which is responsible for the individual aircraft's continuing airworthiness. In this context, the State of Registry must develop or adopt requirements to ensure the continuing airworthiness of aircraft. CASA, or its predecessors, has previously issued AD/CESSNA 500/8, affecting Cessna 500 model aeroplanes. Following an assessment, CASA has cancelled this AD due to the resolution of the unsafe condition identified, and the cancellation will become effective on 25 September 2008. No replacement AD is required as the unsafe condition no longer exists. The process of issuing and cancelling ADs is governed by Australia’s obligations under the Convention on International Civil Aviation, which means that no public consultation has been required for this cancellation. Additionally, the Office of Best Practice Regulation has determined that ADs do not necessitate a Regulatory Impact Statement. The AD cancellation was made by the Manager, Systems and New Technologies, in the Airworthiness Engineering Group, on behalf of CASA, in accordance with subsection 84A(2) of the Act. In terms of consequences, breaches of ADs or failure to comply with the requirements outlined in the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 can lead to civil penalties, criminal charges, or both. The specific penalties can vary depending on the nature and severity of the breach but may include substantial fines, imprisonment, or both. The exact penalties are not specified in the provided text, but they are determined by the courts based on the circumstances of each case.
