Airlines for America Releases ATA 103 Update and New Revision

This month, Airlines for America (A4A) published bulletin 2017.2: Modified ATA 103 Requirements for Filter Monitors, and released a revised ATA 103 (v2017.2) which includes updates from the bulletin and will replace the previous 2017.1 revision. The bulletin and revised ATA 103 come after the IATA SAP Special Interests Group’s position statement regarding filter monitors. Key highlights of the bulletin and revised ATA 103 include a reduction in the maximum differential pressure (DP) for filter monitor elements to 15psid and the addition of section 3.17 to the ATA 103 which details an Aircraft Fueling Nozzle Strainer Cleaning Procedure for Fueling Equipment with Filter Monitors.

Important Industry Update Concerning Monitor Filter Elements

Last month, the International Air Transportation Association (IATA) issued a position statement from their special interest group on Super Absorbent Polymer or, SAP (the media used in EI 1583 filter monitor cartridges), which recommended that filter monitors be phased out of all aviation fuel handling systems. The announcement came after eight separate, documented incidents in which SAP was found downstream in engine/airframe fuel system components.

Following the initial position statement from IATA, several leading industry groups have issued their own statements. As such, Parker’s Velcon Aviation Filtration Division issued Service Bulletin 1217-1, which seeks to clarify the various current positions. The bulletin includes the collective “best practices” of IATA, A4A, JIG, and EI along with Parker’s “go-forward” actions for their EI 1583 qualified monitor elements.

The recommendations include:

  • Fuel filter monitors to meet new 7th edition criteria from the Energy Institute (Implementation period TBD)
  • Maximum allowable monitor vessel differential pressure-15 psid (1 bar) *This is an important reduction from the 22 psid outlined in the latest revision of ATA Spec 103.
  • Differential pressure switches for use on fuel filter monitor housings
  • Change all nozzle hose end strainers to 100 mesh
  • Regular cleaning of the hose end strainer (final procedure and timing TBD)

This is an ongoing issue and NATA will continue to keep you updated on the latest developments as they become available.

 

New Guidelines Announced for Absorbent Monitor Filter Elements

Last week, Airlines for America (A4A) and the International Air Transport Association (IATA) released new guidelines for placing water absorbing monitor filter vessels into service following the replacement of monitor filter elements. The new guidelines call for flushing of the filter vessel prior to placing the vessel into service. For specific guidelines, please click here.
