TROUBLESHOOTING THE M998 ELECT SYST. - OD1617 - LESSON 1/TASK 3
(b) The fault may not be important enough to take time away
from the mission, so repairing the fault can wait until the next
scheduled service or trip to the supporting unit.
(c) The needed repair part is not on hand.
(d) Other reasons, at the CO's discretion.
Faults the CO's designated representative decides to defer go on the
DA Form 2404 DEF MAINT. Print "DA Form 2404 DEF MAINT" in column d
for these items.

(1) Although status symbol X faults cannot be deferred, they may
be downgraded.
The CO, or the maintenance/motor officer, when
designated, may downgrade an X to a circled X. Downgrade an X status
symbol only when the equipment is crucial to the mission, or must be
moved under its own power.
WARNING
Downgrading the X must not put the operator or
crew in danger, or further damage the equipment.
If both conditions cannot be met, the X may not
be downgraded. If the equipment can be operated
safely under specific limits, the X may be
downgraded and the specific limits listed.
If all the conditions for downgrading an X can be met, circle the X
in column b.
(2) Column d--Corrective Action.
(a) Print "Cleared for Limited Operations."
Add the specific
limits under which-the equipment can be operated.
These limits may
involve such factors as speed, mission type, distance, weather, and
time.
The downgrade may affect a subsystem of a system, listed in
Appendix B, section II of DA Pam 738-750.
In that case, the
specified limits must include that part of the mission which the
system can no longer perform.
