tinyclark Posted November 15, 2012 Share Posted November 15, 2012 They are removed and checked during every ISO inspection IAW 2J-T56-56. Quote Link to comment Share on other sites More sharing options...
Lkuest Posted November 15, 2012 Share Posted November 15, 2012 Currently, we do them every ISO, which is a 570 day interval. The ISO cycle used to be 360 days, so they added them to the work cards for the HSC if the aircraft has flown 400 hrs or more since last ISO. Currently in the US Air Force, we fly with JP-8 or Jet-A with no additives, so they tend to need a good cleaning, sometimes even after 150 hrs. I hear the fuel nozzles that flow the +100 additive rarely flow bad at all, so it all depends on what you guys use for fuel as well. Quote Link to comment Share on other sites More sharing options...
