AD/CERES/3 Amdt 1 - Fuel Tank Vent - Modification - CANCELLED

Overview

The Civil Aviation Act 1988 was enacted to regulate civil aviation in Australia with a primary focus on ensuring the safety and efficiency of air navigation. The Act empowers the Governor-General to make regulations that support the Act’s objectives, particularly concerning air navigation safety. The Civil Aviation Safety Regulations 1998, made under the authority of the Act, further detail the regulatory framework, including the issuance of airworthiness directives (ADs) by the Civil Aviation Safety Authority (CASA). These ADs serve as legislative instruments, mandated to ensure the continuing airworthiness of aircraft registered in Australia, in line with international standards set by the Convention on International Civil Aviation. In the context of AD/CERES/3 Amendment 1 for CA-28 aeroplanes, CASA has determined that the unsafe condition addressed by the directive no longer exists, leading to its cancellation effective 9 April 2009. This action adheres to Australia's obligations under international conventions and does not require public consultation or a Regulatory Impact Statement.

Scope and Application

The Civil Aviation Act 1988, complemented by the Civil Aviation Safety Regulations 1998, provides a framework under which the Civil Aviation Safety Authority (CASA) can issue airworthiness directives (ADs) to ensure the safety of air navigation in Australia. These directives are applicable to all kinds of aircraft or aeronautical products within the Australian Register, and CASA, as Australia’s national airworthiness authority, is mandated to assess and, if necessary, issue Australian ADs to enforce the requirements stipulated by the State of Design. This regulatory mechanism aligns with Australia's commitments under Annex 8 of the Convention on International Civil Aviation, where the State of Design has the primary responsibility for the continuing airworthiness of aircraft types, and the State of Registry must implement the necessary measures to maintain airworthiness. The ADs are legislative instruments and are subject to disallowance under the Acts Interpretation Act 1901. In the specific instance of AD/CERES/3 Amendment 1, which affected all models of CA-28 aeroplanes, CASA assessed and subsequently cancelled the directive due to the non-existence of the previously identified unsafe condition, a process that reflects Australia's international obligations and internal safety standards.

Key Provisions

The Civil Aviation Act 1988, particularly section 98, empowers the Governor-General to make regulations that are in the interests of the safety of air navigation. 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 ADs serve as formal notices of known safety deficiencies, and are a common method used by ICAO Contracting States, including Australia, to ensure the continuing airworthiness of aircraft types. The ADs are considered legislative instruments under section 6 of the Legislative Instruments Act 2003 and can be disallowed in accordance with section 46A of the Acts Interpretation Act 1901. Under these regulations, the State of Design is responsible for the continuing airworthiness of an aircraft type and must provide necessary information to the State of Registry to ensure safety. The State of Registry, in turn, must develop or adopt requirements to ensure the continuing airworthiness of aircraft registered in its territory. In Australia, CASA acts as the national airworthiness authority. When an AD is issued by a State of Design against a type of aircraft registered in Australia, CASA is required to assess this information and, if appropriate, issue an Australian AD to enforce the State of Design's requirements. In this context, CASA issued and subsequently cancelled Australian AD/CERES/3 Amendment 1, which affected all models of CA-28 aeroplanes. The cancellation was due to the unsafe condition no longer existing, and as a result, no replacement AD was required. This action was taken in accordance with Australia's obligations under the Convention on International Civil Aviation. Notably, because this AD cancellation was made under these obligations, no consultation with the Australian public or the requirement for a Regulatory Impact Statement was deemed necessary. The AD 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 Civil Aviation Act 1988. In terms of consequences, any failure to comply with the ADs issued by CASA could lead to serious safety risks, and non-compliance could result in penalties under the Civil Aviation Act 1988, which may include fines or imprisonment. The exact penalties depend on the severity of the breach and the specific provisions of the Act and the regulations that apply. However, the Civil Aviation Safety Regulations 1998 themselves do not specify maximum penalties for non-compliance with ADs. Instead, penalties are determined by the courts based on the circumstances of each case and the relevant provisions of the Civil Aviation Act 1988.
