Figure 3-9.–The format of the master repairable item list (MIUL), Parts 1 and 2.
Why should the item(s) be turned in?
Is there special material content?
Is there hazardous material content?
Is the item a depot level repairable?
Mandatory turn-in repairable can be identified by the
material control codes H, E, X, G, or O located in the
third position of the item’s NSN.
For the program to work as intended, you must
return repairable items promptly and in repairable
condition. At the time you present your request for a
mandatory turn-in item, supply must inform you that the
removed part must be returned. Therefore, when you
receive the replacement you are required to do the
following:
Remove the defective item without damaging it
beyond its already defective condition.
Provide adequate protection to the item so it will
not be further damaged before it is turned in to
supply. The most effective way, if at all possible,
is to place the defective part in the same container
in which you received the replacement part.
Resist the temptation to cannibalize the item for
components that you might possibly use
sometime in the future.
Return the defective item to supply as soon as
practical.
Sometimes the needed replacement item is not in
the storeroom; supply must obtain it. Normally, you
should still turn in the failed item, even though you have
not received the replacement item. This way the failed
item can enter the repair cycle and be available for
reissue soon.
NOTE: The exception to this requirement is when
equipment can still be used under limited operation with
the failed part in place until the replacement is received.
If this is the case, you MUST obtain a “Remain in Place”
certification.
You can find information about the packaging for
protection in the technical manual of the equipment
involved. You can also obtain additional information
from the supply department at your command. They
may suggest that you not package the turn-in item
because of any inspections required before shipment or
they may say their shipping personnel have the
necessary materials to package the item properly. There
are two references that you should know about if supply
department personnel are not readily available to assist
you. They are the Afloat Supply Procedures, NAVSUP
Publication 485; and Supply Ashore, NAVSUP
Publication 1.
