REPORTING EQUIPMENT IMPROVEMENT RECOMMENDATIONS (EIR)
If your AFCS or PDIU needs improvement, let us know.
Send us an EIR.
You, the user, are the only one who
can tell us what you don’t like about your equipment.
Let us know why you don’t like the design or performance.
Put it on an SF 368 (Product Quality Deficiency Report).
Mail it to Department of the Army, U.S. Army

SAFETY, CARE, AND HANDLING
a.
AFCS components are equipped with handles to facilitate handling.
All components are within acceptable
weight limits for a one person lift per MIL–STD–1472.
b.
AFCS and PDIU LRUs are protected from Electrostatic Discharge (ESD) when fully assembled; however,
exposed circuit card assemblies (CCAs), connectors, and electronic components are sensitive to ESD.
Whenever removing AFCS and PDIU LRU covers, or handling exposed CCAs or electronic components, ensure
grounded wrist straps are worn and other ESD precautions are observed.
The following documents reference the
required specifications:
(1)
MIL–STD–1686: Electrostatic Discharge Control Program for Protection of Electrical and
Electronic Parts, Assemblies, and Equipment.
(2)
