Overview

The Civil Aviation Safety Regulations 1998 (CASR 1998) were enacted to establish standards for ensuring the safety of civil aviation operations within Australia. This legislation provides a regulatory framework that addresses various aspects of aviation safety, including airworthiness standards, maintenance, and emergency procedures. The Civil Aviation Safety Authority (CASA) issues airworthiness directives under these regulations to mandate corrective actions for identified safety issues. One such directive, AD/A320/155, was issued on 5 August 2004, in response to instances of incomplete inflation of emergency escape slides on Airbus A318, A319, A320, and A321 series aircraft. The directive requires modification of certain passenger door emergency escape slides to prevent potential delays in passenger egress during emergency evacuations. This action was taken to rectify the unsafe condition identified, ensuring that the aircraft meet the necessary safety standards set forth by the CASR 1998.

Scope and Application

The Civil Aviation Safety Regulations 1998, specifically Part 39, outlines Airworthiness Directives which are mandatory orders issued by the Civil Aviation Safety Authority (CASA) to address identified safety issues. These directives apply to specific types of aircraft, in this case, Airbus Industrie A319, A320, and A321 series aeroplanes. The Airworthiness Directive AD/A320/155 focuses on passenger door emergency escape slides for these models, requiring modifications to ensure they meet safety standards. The directive applies to aircraft equipped with specific emergency escape slide part numbers, excluding those that have already incorporated certain Airbus modifications or service bulletins. The directive mandates that all affected emergency escape slides must be modified according to Airbus Service Bulletin A320-25-1338 and requires compliance before 30 June 2007. The directive became effective on 5 August 2004, and was subsequently notified in the Commonwealth of Australia Gazette on 14 July 2004.

Key Provisions

The Civil Aviation Safety Regulations 1998, Part 39 - 105, include a specific Airworthiness Directive (AD) for Airbus Industrie A319, A320 and A321 Series Aeroplanes, which focuses on passenger door emergency escape slides. This AD, identified as AD/A320/155 and issued on 8/2004, applies to certain models of these aircraft equipped with specific forward or aft passenger door emergency escape slide parts that have not been modified in line with Airbus Modification 33429 or Airbus Service Bulletin A320-25-1338. The directive requires all such door emergency escape slides to be modified according to the specifications laid out in Airbus Service Bulletin A320-25-1338. This requirement is necessitated by previous incidents where emergency escape slides did not fully inflate during tests, which was traced to ruptures at the end fittings due to interference with the slide fabric during inflation. Such incomplete inflations could potentially delay passenger evacuation in the event of an emergency. The obligations imposed by this AD are clear and specific. Operators of affected aircraft must ensure that the emergency escape slides are modified in accordance with the Airbus Service Bulletin A320-25-1338 before the compliance deadline of 30 June 2007. Failure to comply with this directive could compromise the safety of passengers during an evacuation, as incomplete inflation of escape slides can significantly hinder egress. Operators must therefore take all necessary steps to ensure that their aircraft meet these safety standards and that the modifications are carried out by competent personnel following the instructions provided in the bulletin. Breach of the requirements set out in this Airworthiness Directive can lead to serious consequences. While the regulations do not explicitly outline criminal or civil penalties for non-compliance, the potential for severe safety incidents cannot be understated. The AD is enforced by the Civil Aviation Safety Authority (CASA), which has the authority to take action against non-compliant aircraft operators. Such actions could include grounding the affected aircraft, imposing fines, or taking legal action to ensure compliance with safety standards. The overarching goal of these measures is to protect public safety and maintain the highest standards of airworthiness for all aircraft operating within Australia.
