echanics, stopping sand from blowing into your Black Hawk’s No. 1 inlet particle
separator (IPS) prevents extra maintenance.
The problem with the No.1 IPS blower is that it sits in a place on the Black Hawk that
allows sand to get in easily.
Fine sand getting into the No. 1 IPS blower can wear out the Axis-G seal on the accessory
gearbox of the engine. If that happens and the seal goes bad, oil will blow out through the
IPS duct blower.
Keeping the No. 1 IPS blower covered in a sandy environment protects the seal from
sand and prevents oil gear box leakage.
To keep sand out of the IPS duct, cut a piece of unserviceable inlet plug the size of the
hole and place it into the duct with a REMOVE BEFORE FLIGHT streamer attached.
The No. 2 IPS blower doesn’t have that problem, because it’s not
as exposed to sand.
