AD/PA-36/10 - Spray Pump Windmill - Modification - CANCELLED

Overview

The Civil Aviation Act 1988, enacted by the Commonwealth Parliament, establishes the legislative framework for ensuring the safety of civil aviation in Australia. The Act empowers the Governor-General to make regulations aimed at safeguarding air navigation, with the Civil Aviation Safety Regulations 1998 further detailing the operational requirements and safety standards for aircraft and aeronautical products. One such regulation, 39.001, allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. In line with international obligations under Annex 8 to the Convention on International Civil Aviation, CASA has the authority to issue and subsequently cancel ADs to maintain the continuing airworthiness of aircraft within Australia, ensuring compliance with both domestic and international safety standards. In the case of AD/PA-36/10, affecting Piper PA-36 agricultural aircraft with Agrinautics liquid dispersal equipment, CASA reviewed and subsequently cancelled the directive effective 12 March 2009. This action aligns with Australia’s responsibilities under the Convention, eliminating the need for public consultation. Additionally, the Office of Best Practice Regulation has determined that ADs do not necessitate a Regulatory Impact Statement. The cancellation was authorised by the Manager, Systems and New Technologies in the Airworthiness Engineering Group, on behalf of CASA, in accordance with the Act.

Scope and Application

The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 together establish a framework for the issuance of airworthiness directives by the Civil Aviation Safety Authority (CASA) to ensure the safety of air navigation. These regulations apply to all aircraft within Australia's jurisdiction, and any entities or individuals responsible for the maintenance, operation, or certification of such aircraft. The geographic reach of these regulations is national, aligning with Australia's obligations under international agreements such as the Convention on International Civil Aviation. An airworthiness directive is a legislative instrument and is subject to disallowance under the Acts Interpretation Act 1901. The State of Design and the State of Registry bear specific responsibilities for the continuing airworthiness of aircraft, with CASA acting in accordance with these international standards. In this particular case, CASA has issued and subsequently cancelled AD/PA-36/10 concerning Piper PA-36 agricultural aircraft equipped with Agrinautics liquid dispersal equipment, effective from 12 March 2009. This cancellation was made without public consultation as it was necessitated by Australia’s international obligations and does not require a Regulatory Impact Statement. The AD was made by the Manager, Systems and New Technologies in the Airworthiness Engineering Group on behalf of CASA, in accordance with the Act.

Key Provisions

The Civil Aviation Act 1988, particularly section 98, empowers the Governor-General to make regulations aimed at ensuring the safety of air navigation. Section 39.001 of the Civil Aviation Safety Regulations 1998 allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for certain types of aircraft or aeronautical products. These directives are considered disallowable instruments under section 46A of the Acts Interpretation Act 1901, making them subject to the scrutiny outlined in the Legislative Instruments Act 2003. The obligations imposed by these provisions require CASA to ensure that aircraft maintain their airworthiness, which includes issuing directives that address potential safety issues. The State of Design is mandated to provide necessary information to ensure the continuing airworthiness of aircraft types, while the State of Registry must implement or adopt measures to ensure the ongoing airworthiness of individual aircraft registered within its jurisdiction. CASA has a duty to review and, if necessary, issue directives to mitigate any identified safety concerns. There are no explicit offences, penalties, or consequences outlined in the provided text for the breach of airworthiness directives. However, the overarching regulatory framework within which these directives operate suggests that non-compliance could lead to enforcement actions under the Civil Aviation Act 1988. Such actions might include administrative penalties, the grounding of non-compliant aircraft, or other measures to enforce compliance and ensure public safety. In summary, the Civil Aviation Safety Regulations 1998 and the Civil Aviation Act 1988 establish a framework for the issuance of airworthiness directives by CASA. These directives are critical for maintaining the safety and airworthiness of aircraft, with obligations resting on both the State of Design and the State of Registry. The text does not specify penalties for non-compliance, but the regulatory context implies that such non-compliance could lead to significant enforcement actions to safeguard public safety.
