olding the Kiowa Warrior’s M296 machine gun with the umbilical cable still
attached to the side-welded aft cage bracket can damage the cable and cage. You can
bend or snap off the bracket and pull the connector off the cable.
The cable is not long enough to span the added distance when folding up the
universal weapon’s pylon (UWP) with the cable connected to the side-welded aft
cage bracket.
To make matters worse, the umbilical cable is usually wrapped around the pylon
mounting arm to keep it out of harm’s way. That just makes the cable even shorter.
The simple solution is to disconnect the cable before folding the gun.
The permanent solution is to move the bracket from the side to the top of the aft
cage. The procedure is in Appendix I-2 of TM 9-1090-214-23&P. With the bracket
moved to the top of the cage and the cable not wrapped around the UMP, the cable
should be long enough to fold without damaging the cage or the cable.
Anytime you remove components from your helicopter for turn-in, make sure the
components have been properly evaluated, cleaned, inspected and tagged. Then ensure
that the caps and plugs are installed before turning them in to support.
There’s a tendency to think that if components have problems, you just remove ‘em,
tag ‘em and turn them in to the support shop because support is a one-stop shop to Fx
everything.
It’s not support’s job to clean dirty control heads, or avionic components, drain fluid
from removed hydraulic components or perform other tasks that you can do yourself.
Never turn in a component to support until all the cleaning, inspecting, trouble-
shooting and proper paperwork is complete. That way, the turn-around time for component
repair will not be delayed because the unit didn’t perform the correct turn-in procedure.
New aft cages from the supply system will have the bracket mounted on the side.
Have your support shop remove and weld the bracket to the top of the aft cage to
prevent future damage.
