Operators, if you maintain the Shadow UAV, make a note that there may be contaminated synthetic oil (PN 60578-2) within the Shadow fleet.

Before using oil in your Shadow, make sure there’s no visible contamination. Users are reporting cloudy, sticky and milky oil, full of contaminants. The affected lot numbers are 52138 and 52734. These lots have been recalled and removed from log point inventories.

Locally, check your POL inventories for lots 52138 and 52734 and turn in affected oil in its original container to your supporting field service representative (FSR). Also, if you feel you have used affected oil in your aerial vehicle (AV), drain and flush the AV oil bladders and contact your supporting FSR for assistance.
