JIG Bulletin 105 informed users of Filter Monitor systems of the events that supported the industry developing a roadmap to progressively phase out Filter Monitors. Bulletin 105 also defined actions that are believed to provide additional mitigation of potential SAP migration from Filter Monitors, whilst the industry is working to develop replacement filtration technologies suitable for aircraft fuelling.

Introducing new filtration technology into the field.
Before new filtration technology can be introduced into the field, the filter supplier(s) are required to successfully complete qualification testing of their filters/sensors in the laboratory, against the relevant EI specification. However, qualification testing in isolation only provides a limited assurance to the end user due to the inherent limitations associated with testing under controlled, laboratory conditions. It is noted that qualification testing of known technology is based on successful history of field performance, whilst this is not the case with new technology and further work becomes necessary.
Therefore, for new technology, additional testing for robustness evaluation followed by field trials are also required. New filtration systems are then included in JIG standards, only when JIG has received robust evidence of the suitability of these systems for aircraft fuelling operations, derived from an extensive field evaluation and assessment.
