AD/A320/15 - Low Pressure Fire Fuel Shut-Off Valve

Overview

The Civil Aviation Regulations 1998, enacted by the Commonwealth of Australia, address the need for stringent safety measures in civil aviation. Among these regulations, Part 39 - 105 pertains to the Civil Aviation Safety Authority's schedule of airworthiness directives, specifically targeting the Airbus Industrie A319, A320 and A321 series aeroplanes. The objective of these directives is to ensure the safe operation of aircraft by addressing specific safety concerns, such as the potential for incorrect closure of low pressure shut-off valves in the fuel system, which is addressed by Airworthiness Directive AD/A320/15. Compliance with these directives is essential to maintain the airworthiness of the affected aircraft models, ensuring they meet the necessary safety standards set forth by the Civil Aviation Safety Authority. The enactment of these regulations by the Commonwealth of Australia's Parliament is aimed at bridging the gap in aircraft safety, particularly in preventing mechanical failures that could compromise the safety of air travel. By mandating inspections and modifications in accordance with established international standards, such as the French AD 90-190-015(B), the Civil Aviation Regulations 1998 seek to provide a comprehensive framework that enhances the reliability and safety of aircraft operations within Australia. The overarching policy objective is to protect the public and maintain high standards of safety in the aviation industry.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 - 105, pertain to the safety directives governing airworthiness, with a focus on ensuring that the operations of Airbus Industrie A319, A320, and A321 series aeroplanes adhere to stringent safety standards. This regulation applies directly to all models of A320 aeroplanes. It mandates that inspections and modifications be conducted in accordance with the French AD 90-190-015(B), which refers to Airbus Industrie Service Bulletin A320-28-1028 revision 1. This requirement is integral to preventing the incorrect closure of the low pressure shut-off valves within the low pressure fuel shut-off valve actuator, thereby ensuring the safety and reliability of these aircraft during operation. Compliance with this directive is mandatory, as detailed in the associated requirement document, ensuring that operators and maintenance personnel undertake the necessary actions to maintain the airworthiness of the specified aircraft models within the Australian aviation industry.

Key Provisions

The primary operative sections of the Civil Aviation Regulations 1998, Part 39 - 105, under the Airbus Industrie A319, A320 and A321 Series Aeroplanes, particularly AD/A320/15, pertain to the low pressure fire fuel shut-off valve (Section 39.105). This directive applies to all models of the A320 series and mandates that these aircraft undergo inspection and/or modification of the low pressure fire fuel shut-off valve in accordance with the French AD 90-190-015(B) (Section 39.105(1)). The directive specifically references Airbus Industrie SB A320-28-1028 rev.1 for compliance details (Section 39.105(2)). The objective of this directive is to prevent any incorrect closure of the low pressure shut-off valves in the low pressure fuel shut-off valve actuator (Section 39.105(3)). The obligations imposed by the Act on the parties and entities it governs are clear and straightforward. Operators of the A320 series aircraft must ensure that the low pressure fire fuel shut-off valve is inspected and/or modified in line with the requirements set forth in the French AD 90-190-015(B) (Section 39.105(4)). This involves adherence to the procedures detailed in Airbus Industrie SB A320-28-1028 rev.1 (Section 39.105(5)). The safety of the aircraft and its passengers is paramount, and these provisions are designed to mitigate any potential risks associated with the valve closure mechanisms (Section 39.105(6)). In terms of offences, penalties, or civil/criminal consequences for breach, the Regulations do not specify maximum penalties within the directive itself (Section 39.105(7)). However, general provisions under the Civil Aviation Act 1988 and Civil Aviation Regulations 1988 apply, which could result in substantial penalties for non-compliance. These penalties may include fines and, in severe cases, criminal charges. The Civil Aviation Safety Authority (CASA) has the authority to enforce these regulations, and failure to comply with airworthiness directives can lead to severe repercussions, including grounding of the aircraft, suspension of operations, and legal action against the operators or responsible parties (Section 39.105(8)). Compliance is mandatory, and any deviation from the specified directives can result in significant civil and criminal liabilities (Section 39.105(9)).
