Overview

The Civil Aviation Safety Regulations 1998 (CASR) were enacted to ensure the safety of civil aviation in Australia. This legislation was introduced to address the need for a comprehensive regulatory framework governing the safety aspects of civil aviation operations, including aircraft design, manufacture, maintenance, and operation. The Civil Aviation Safety Authority (CASA), as the delegate of the Australian Government, was tasked with implementing and enforcing these regulations. The policy objective of the CASR is to maintain and enhance the safety of civil aviation in Australia through the establishment of stringent safety standards and requirements, which are periodically reviewed and updated to reflect technological advancements and evolving safety concerns. One such regulation, Airworthiness Directive AD/A320/156 issued in August 2004, mandates the removal of specific maintenance lights in Airbus Industrie A319, A320, and A321 series aeroplanes to mitigate the risk of fuel vapour ignition in the hydraulic bay area.

Scope and Application

The Airworthiness Directive (AD) issued under the Civil Aviation Safety Regulations 1998 applies to all Airbus Industrie A318, A319, A320 and A321 series aeroplanes except those that have incorporated Airbus Industrie Modification 33518 during production or Airbus Industrie Service Bulletin (SB) A320-92-1032 dated 8 March 2004. The AD mandates the removal of the maintenance light with part number 2LA002606-01 from the hydraulic bay and the disconnection of the associated electrical wiring in accordance with SB A320-92-1032. The requirement must be fulfilled before 31 December 2005, and the directive became effective on 5 August 2004. The directive is issued by a delegate of the Civil Aviation Safety Authority (CASA) and is applicable within the national jurisdiction of Australia. The AD was notified in the Commonwealth of Australia Gazette on 14 July 2004, and while the AD itself does not specify any exclusions, certain modifications or service bulletins can exempt specific aircraft from the requirement.

Key Provisions

This Airworthiness Directive (AD) pertains to Airbus Industrie A319, A320 and A321 Series Aeroplanes, specifically addressing the removal of maintenance lights in the hydraulic bay to mitigate explosion risks. According to the AD/A320/156 issued on 8 August 2004, the directive applies to all Airbus A318, A319, A320 and A321 series aeroplanes, except those that have already incorporated certain modifications or service bulletins during production or in service (section 2). The requirement of the directive is that the maintenance light with part number (P/N) 2LA002606-01 must be removed from the hydraulic bay and the electrical wiring must be disconnected in accordance with Service Bulletin (SB) A320-92-1032 (section 3). Compliance with this directive must be achieved before 31 December 2005 (section 4). Entities governed by this AD are obligated to ensure that the specified maintenance lights are removed and the electrical wiring is disconnected as directed, unless the aircraft has already incorporated the relevant modifications or service bulletins. The directive is intended to address a safety hazard identified in the hydraulic bay area, which could potentially lead to fuel vapour ignition. This necessitates immediate action from aircraft operators and maintenance personnel to comply with the directive and maintain airworthiness standards. Breach of this Airworthiness Directive could lead to serious consequences, as it directly impacts the safety of the aircraft. While the Civil Aviation Safety Regulations 1998 (CASR) do not specify the exact penalties for non-compliance with ADs in this context, failure to comply could result in severe regulatory action, including grounding of the aircraft until the necessary actions are taken. Additionally, there may be implications for airworthiness certificates and operational approvals, which could affect the ability of the aircraft to legally operate. The potential for civil or criminal liability also exists, depending on the circumstances of the breach and its impact on aviation safety.
