FILTER MONITOR PHASE OUT - BULLETINS, UPDATES, TECHNICAL NEWS

All the updates on JIG's work to phase out SAP-based Filter Monitor technology from jet-fuel handling applications. Starting with Bulletin 105 to the latest Field Trial updates.

Since the IATA-led Special Interest Group published its report in 2017, SAP-based Filter Monitor filtration was identified as a potential risk to flight safety. The industry immediately put in place mitigating actions detailed in JIG’s Bulletin 105, backed up with the development of the EI1583 7th edition specification, and is committed to phasing out Filter Monitors from operations.

A Joint Industry Field Trial programme was started by JIG in cooperation with IATA and A4A to conduct operational trials on new filtration technology developed by the manufacturers and qualified to a relevant EI (Energy Institute) Specification. The Field Trials have been running since July 2019 and have so far resulted in the adoption of Electronic Water Sensor and Dirt Defence filter combinations for into-plane use. (Bulletin 130). Further details on new technologies being field trialled or in development can be found below.

LATEST FIELD TRIAL INFORMATION (December 2021)

PARKER WATER BARRIER FILTER

The Field Trials for the Water Barrier Filter (CDFX) produced by Parker Velcon have shown so far that the technology is effective in removing water from fuel. However, it is also showing variable service life due to reaching maximum differential pressure (dP).

The technology has rapidly reached maximum dP at locations where the fuel was confirmed on-specification and other filtration technology in use at the same location was not affected. A total of 12 sets of elements has already reached the maximum 22psi.

Laboratory work conducted by Parker has revealed ultra-fine particulate build up on the filtration media. This is the presumed cause of premature high dP, though the underlying sources and likely occurrence of particulate build-up remain unknown.

Whilst the Trials may not reflect conditions experienced at all locations, Operators considering this technology should be aware that the achieved volume throughput, if repeated at a major hub location, would require very frequent change-out of elements.

There is further work ongoing with the EI and with Parker Velcon to resolve some areas of uncertainty in the manufacturing process that may delay the completion of the Field Trial evaluation.

FACET WATER CONTAINMENT TECHNOLOGY

This technology remains in product development stage. Progress has been presented to Industry Groups on various occasions and the manufacturer is continuing to work with the EI and the engine/airframe OEMs on questions that have been raised. There is still no Qualification Standard written by the EI for this technology, meaning that this technology – or a further development of the concept – will not be adopted into the Standards in the next 1-2 years and may never be.

JIG has set a date of July 2023 to no longer reference EI1583 qualified Filter Monitors in the Standards (Bulletin 132).

Field Trials are continuing and this page will be regularly updated on progress. JIG publishes periodic Technical Newsletters (link to TN #10) to keep members informed about the Field trials and any other information related to filter-monitor phase out.
