Figure 1-14. EOS codes for DA Form 2406.
1 List first the EOS code for the subsystem affecting the most
equipment, or failing most often.
2 List second the EOS code for the subsystem causing the next
(g) Identify the EOS of a subsystem in the first (primary) position and
then list EOS "Z" in the second position when a system problem is primarily caused by a
shortage of a particular subsystem. Never use EOS "Z" by itself; always use "Z" in the
secondary position so the subsystem shortage is clearly identified.
(h) Use EOS whenever nonavailable time for system is reported.
(i) Use N (other subsystem problems) when problems occur with a
mission critical subsystem not assigned a specific EOS code.

(a) Leave block 9b(3) blank if the line is an authorized line with
separate models below it.
