Bulletin 130
The aviation industry has worked continuously over the past several years to develop and evaluate new technology to replace Super Absorbent Polymer (SAP)-based filter monitors (FM), without the need for vessel configuration changes (drop-in replacement elements). The ultimate objective remains unchanged: to eliminate SAP-based filtration from all aviation fuel handling applications for the reasons explained in JIG Bulletin 105 and the documents referenced therein.
A joint industry programme designed and funded by JIG, IATA and A4A – the Joint Industry Filtration Field Trial Group – was established in 2018 to conduct field evaluation of new filtration/sensing technology. The scope of this joint field evaluation scheme includes only technology that has successfully completed the required EI qualification testing and technical evaluation for robustness. Progress on the technical and field evaluation of available replacement technologies has been communicated by JIG through regular Technical Newsletters since the onset of the programme.
The field evaluation process that was followed for the combination of the Dirt Defence Filters (DDF) – Electronic Water Sensor (EWS) shown in the table below has been completed. The review of the field evaluation results from the joint industry group has demonstrated that, in the environments in which these systems were tested, they prevent dirt and free water from reaching the aircraft, are durable in mobile applications and have sufficient life for routine operations. It was therefore confirmed by the joint industry group that the tested combinations met the acceptance criteria defined in the field trial protocol. As a result, the joint industry group has recommended the adoption of the tested combinations listed below into the standards.
This Bulletin lists the combination of technologies that may be fitted to refuelling vehicles to replace Filter Monitors.
A Failure Modes and Effects Analysis has been conducted to give guidance to operators on correct installation procedures and risk evaluation of critical parts and circuits.
A thorough Management of Change exercise is expected of Operators.
Further details of the electronic sensor installaton, settings and calibration are given.
STANDARDS CHANGE
With effect from 24th August 2020, Entities operating in accordance with JIG standards may use the DDF/EWS technology introduced in this document, in accordance with the requirements detailed in this document.
REQUIRED ACTION
24th August 2020
Operators introducing the technology introduced in this Bulletin shall establish a risk-based Management of Change plan as explained in this document.
RECOMMENDED PRACTICE
24th August 2020
Operators introducing the technology introduced in this Bulletin should perform their own evaluation prior to full implementation.
