AD/RAD/5 - Collins Glide Slope Receivers, Flag Alarm and Deviation Circuits - Modification

Overview

The Civil Aviation Regulations 1998, specifically within Part 39 - 107 Civil Aviation Safety Authority Schedule of Airworthiness Directives, address the need for stringent oversight of radio communication and navigation equipment used in civil aviation. Enacted by the Australian Government, this legislation is designed to ensure that all aircraft meet safety standards, particularly in relation to the installation and modification of critical equipment such as Collins Glide Slope Receivers. The policy objective underpinning these regulations is to enhance the safety and reliability of aviation operations by mandating specific modifications and compliance checks on essential navigational equipment. This approach ensures that aviation safety standards are consistently upheld, thereby protecting both passengers and crew in the operation of civil aircraft.

Scope and Application

The Civil Aviation Regulations 1998, under the legislative instrument F2006B06507, specifically address the airworthiness directives related to radio communication and navigation equipment, notably the Collins Glide Slope Receivers 51V-1 and 51V-2. These regulations apply to all aircraft equipped with the specified Collins Glide Slope Receivers, necessitating modifications to the flag alarm and deviation circuits to ensure compliance with safety standards. The modifications must be carried out in accordance with either Collins Service Bulletins No. 13 for the 51V-1 equipment and No. 9 for the 51V-2 equipment, or the Airworthiness Notice (ANO) 107.9.11.2.1, Issue 2, prior to the installation of the equipment in any aircraft. This directive underscores the importance of stringent safety protocols within the aviation industry, ensuring that all equipment meets the requisite standards before being utilised in flight operations. The regulations are part of a broader framework established by the Commonwealth of Australia to maintain and enhance civil aviation safety.

Key Provisions

The main operative sections of this legislation (Civil Aviation Regulations 1998) focus on ensuring the airworthiness of radio communication and navigation equipment, specifically Collins Glide Slope Receivers 51V-1 and 51V-2, as outlined in AD/RAD/5. According to section 107.9.11.2.1, these receivers must comply with specific service bulletins or airworthiness directives before installation in an aircraft. The Collins SB No. 13 pertains to the 51V-1 equipment, while Collins SB No. 9 pertains to the 51V-2 equipment. These service bulletins detail necessary modifications to the flag alarm and deviation circuits to ensure the equipment's airworthiness. The Act imposes specific obligations on the entities governed by it, primarily requiring compliance with the outlined modifications and procedures for the Collins Glide Slope Receivers. This includes adherence to the instructions provided in the relevant service bulletins, ensuring that any modifications are completed accurately and before the equipment is installed in an aircraft. The regulations are designed to ensure that all modifications and installations meet the required safety standards set by the Civil Aviation Safety Authority (CASA). Breaching the requirements set forth in the Civil Aviation Regulations can lead to significant consequences. The Act does not explicitly state penalties within the provided text, but generally, violations of these regulations can result in civil or criminal penalties under broader aviation laws. For instance, failure to comply with airworthiness directives can lead to enforcement actions by CASA, which might include fines, suspension or revocation of aircraft operating certificates, or even criminal charges if the breach results in a safety hazard or incident. The exact penalties would depend on the severity of the breach and any relevant aviation legislation.
