AD/A320/143 Amdt 1 - Fuel Tank Electrical Bonding

Overview

The Civil Aviation Safety Regulations 1998 (CASR 1998) were enacted to establish safety standards and regulations governing civil aviation in Australia. This legislation was introduced by the Commonwealth Parliament to address safety concerns and ensure the protection of life and property within the civil aviation industry. The CASR 1998 provides the Civil Aviation Safety Authority (CASA) with the authority to issue airworthiness directives, as demonstrated in Airworthiness Directive AD/A320/143 Amendment 1. This particular directive, issued under subregulation 39.1 (1) of CASR 1998, aims to address an unsafe condition concerning insufficient electrical bonding in the fuel tanks of Airbus Industrie A319 and A320 series aeroplanes. The policy objective of this directive is to mitigate the risk of electrical arcing inside the fuel tanks, which could potentially result in ignition of fuel vapours and cause a fuel tank explosion under certain conditions, such as lightning strikes or static charge accumulation.

Scope and Application

This legislative instrument pertains to the Civil Aviation Safety Regulations 1998 (CASR 1998), specifically addressing Airworthiness Directives for certain Airbus aircraft models. The Civil Aviation Safety Authority (CASA) has issued Airworthiness Directive AD/A320/143 Amendment 1, focusing on electrical bonding modifications for Airbus A319 and A320 series aeroplanes. The directive applies to all A319 and A320 series aeroplanes that do not have Airbus modification 31888 embodied during production or Airbus Service Bulletin (SB) A320-28-1103 dated 14 June 2002 incorporated whilst in service. The requirement is to modify the aeroplane by incorporating improved electrical bonding in the fuel tanks according to SB A320-28-1103 Revision 1 dated 1 April 2003. The compliance date for this action is before 31 December 2007, with the amendment becoming effective on 15 April 2004. This legislative instrument operates under the Commonwealth of Australia and extends to all relevant aircraft operating within its jurisdiction.

Key Provisions

The Civil Aviation Safety Regulations 1998, Part 39, Section 105 outlines a specific Airworthiness Directive (AD) that applies to Airbus Industrie A319 and A320 series aeroplanes. This directive, AD/A320/143 Amendment 1, focuses on the modification of fuel tank electrical bonding to prevent potential hazards such as electrical arcing that could lead to fuel tank explosions. The directive applies to all A319 and A320 series aeroplanes that do not have either Airbus modification 31888 incorporated during production or Airbus Service Bulletin (SB) A320-28-1103 dated 14 June 2002 integrated into their service history. The directive requires that these aeroplanes must incorporate improved electrical bonding in the fuel tanks in accordance with SB A320-28-1103 Revision 1 dated 1 April 2003. The modification must be completed before 31 December 2007. The obligations imposed by this Airworthiness Directive are clear and specific. Aircraft operators and maintenance personnel must ensure that the aeroplanes covered by this directive are modified to include the improved electrical bonding as per the referenced service bulletin. This requirement is critical to prevent the unsafe condition identified, which could result from insufficient electrical bonding leading to electrical arcing in the fuel tanks. The directive also specifies that the modifications must be carried out in accordance with the instructions provided in the referenced service bulletin. Compliance with this directive is mandatory, and failure to adhere to the stipulated timelines and requirements can result in serious safety implications. The consequences for non-compliance with this Airworthiness Directive are significant. While the Civil Aviation Safety Regulations 1998 do not explicitly state the specific civil or criminal penalties for failing to comply with AD/A320/143, non-compliance with airworthiness directives can lead to severe regulatory actions. These may include grounding of the aircraft, imposition of fines, or even criminal charges if the non-compliance results in an accident or incident. The Civil Aviation Safety Authority (CASA) has the authority to enforce compliance and may take action against operators or maintenance entities that do not adhere to the directives. It is therefore imperative for all parties involved to ensure strict adherence to the requirements outlined in this directive to maintain the airworthiness of the affected aircraft.
