AD/RAD/9 Amdt 1 - Rexair Amspeaker - Fuse Installation

Overview

The Civil Aviation Regulations 1998, enacted by the Parliament of the Commonwealth of Australia, constitute a comprehensive set of regulations governing civil aviation within the country. This legislation was introduced to ensure the safety and efficiency of civil aviation operations in Australia. Among these regulations, Part 39 addresses various safety directives, including those related to airworthiness and equipment standards. One such directive, AD/RAD/9 Amendment 1, focuses on the installation of a 2 amp fuse in Rexair Amspeaker series ACS-1A/1D and ACS-2/2A equipment to enhance safety. The policy objective underpinning these regulations is to maintain and improve the safety of civil aviation through stringent equipment standards and compliance requirements.

Scope and Application

The Civil Aviation Safety Authority (CASA) issues Airworthiness Directives (ADs) under the Civil Aviation Regulations 1998, which apply to specific aircraft models and components to ensure safety and airworthiness. The specific AD/RAD/9 Amendment 1 pertains to the installation of a 2 amp fuse in series with the positive primary DC supply to the Rexair Amspeaker series ACS-1A/1D and ACS-2/2A, requiring the fuse to be mounted in a fuseholder permanently affixed to the equipment. Compliance with this directive must be achieved before 1 January 1964, and adherence can be demonstrated through Rex Aviation Ltd. Engineering Order No. 191. This regulation applies specifically to the identified models of Rexair Amspeaker equipment, affecting the relevant aviation industry and entities involved in the maintenance and operation of these aircraft components. There are no stated exclusions or exemptions in this directive, and the requirement applies nationally across Australia as per the Civil Aviation Regulations 1998.

Key Provisions

The Civil Aviation Regulations 1998, specifically Part 39 - 107, outline the requirements for ensuring the airworthiness of certain radio communication and navigation equipment. The legislative instrument F2006B06539, AD/RAD/9 Amendment 1, focuses on the installation of a fuse in Rexair Amspeaker series equipment, namely the ACS-1A/1D and ACS-2/2A models. Section 10/63 mandates that a 2 amp fuse must be installed in series with the positive primary DC supply to the equipment, and it must be mounted in a fuseholder that is permanently affixed to the equipment. Rex Aviation Ltd. Engineering Order No. 191 is provided as an acceptable means of compliance for this directive. The obligations under this regulation are clear and precise. Operators and maintainers of the specified Rexair Amspeaker equipment must ensure that the installation of the 2 amp fuse in series with the DC supply is completed before the compliance deadline of 1 January 1964. This involves not only the physical installation of the fuse but also ensuring that it is securely mounted in a fuseholder that is permanently attached to the equipment. This requirement ensures the safety and reliability of the equipment in operation. Failure to comply with the provisions outlined in AD/RAD/9 Amendment 1 may result in severe consequences. The Civil Aviation Safety Authority (CASA) enforces these regulations strictly, and any breach of the requirements could lead to significant civil or criminal penalties. Although the specific penalties are not detailed in the provided text, breaches of airworthiness directives are typically taken very seriously, with potential outcomes including fines, operational restrictions, or even grounding of the affected aircraft until compliance is achieved. These measures are in place to uphold the high safety standards required in civil aviation.
