Explanation
Items with these codes are not to be requested/requisitioned individually. They
must be made from bulk material which is identified by the part number in the
DESCRIPTION and USABLE ON CODE (UOC) column and listed in the Bulk
Material group of the repair parts list in the RPSTL. If the item is authorized
to you by the 3rd position code of the SMR code, the source code indicates
it is made at a higher level, order the item from the higher level of
maintenance.
Explanation
Items with these codes are not to be requested/requisitioned individually. The
parts that make up the assembled item must be requisitioned or fabricated and
assembled at the level of maintenance indicated by the source code. If the 3rd
position code of the SMR code authorizes you to replace the item, but the source
code indicates the item assembled at a higher level, order the item from the
higher level of maintenance.
