Important Changes to ATA 103 – Standards for Jet Fuel Quality Control at Airports

UDPATE: The maximum DP for filter monitors referenced with-in this article has been reverted back to 15psi. See our other NATA SafetyNet blog posts for the latest concerning filter monitors and other industry news.

This month, Airlines for America (A4A) announced several significant changes to their ATA 103 Specification – Standards for Jet Fuel Quality Control at Airports. Chief among these changes is an extension of coalescer filter elements from a one-year replacement schedule to a three-year replacement schedule. The coalescer filter housings are still required to be opened and inspected annually for cleanliness and element integrity, and the maximum allowable differential pressure (DP) remains 15psi. Monitor filter elements had their maximum allowable DP extended to 22psi, but are still required to be replaced annually. Another important change came in the elimination of the required monthly upstream membrane color/particle check, or “Millipore” test (downstream testing is still required monthly).

 

The announcement came after a “comprehensive review and update” by the A4A Fuel Technical Committee, and included several other key highlights. The new revision ATA 103 2017.1 is expected to be published next month, and will include additional updates not outlined in the announcement.  A copy of the full announcement can be viewed here.
