Notice to All FBOs Servicing Commercial Airlines: Upcoming Deadline for Filter Monitor Transition Plans is January 15th, 2025

Back Member Updates / January 10, 2025

The deadline for all into-plane refueling operators servicing commercial airlines to submit site-specific transition plans for the upcoming phase-out of EI 1583 7th edition qualified filter monitors is imminent.

This requirement, established by Airlines for America, A4A Bulletin 2024.3 (issued October 4, 2024), mandates that all into-plane refueling operators servicing commercial airlines provide their transition plans by January 15th, 2025.

Key Points to Remember: 

January 15th: 

  • Is NOT the date by which equipment must be converted to a new filter technology.
  • IS the date by which refueling operators must submit their transition plans, outlining how they will replace filter monitors with alternative filtration technologies.

Transition Plan Requirements: 

  1. Identify each piece of aircraft fueling equipment (i.e.: fuel trucks) that services airlines AND is equipped with filter monitors.  ​​​​​​
  2. Specify the alternative filtration technology to which each unit equipped with filter monitors will be converted and estimated completion dates.

Acceptable Filtration Technologies (per Spec 103: Jet Fuel Quality Control at Airports, Revision 2023.1): 

  • Filter Water Separators (FWS): Must meet EI 1581, latest edition.
  • Dirt Defense Filters (DDF) with Electronic Water Sensor (EWS) System: Must meet EI 1599 (DDF) and EI 1598 (EWS), latest editions. ​​​​​​
  • Water Barrier Filters (WBF): Must meet EI 1588, latest edition.
