Classification (FSC) that groups similar items into
classes. The last 9 digits of the NSN is the National Item
Identification Number (NIIN). The first 2 digits of the
NIIN identifies the NATO country that cataloged the
item, and the last 7 digits identifies the item.
As pointed out above, NSN numbers provide you
with the federal class of the item (first 4 digits), what
country cataloged the item (digits 5 and 6). and the item
identification number (last 7 digits).
Part III of the COSAL is the section used to cross-
reference manufacturers part numbers to NSNs.
REPAIR PARTS CONTROL
Each maintenance department is required to
maintain control over repair parts. One of the biggest
problems in some maintenance programs is the control
of direct turnover (DTO) repair parts. DTO parts are
those ordered for direct turnover to the user.
For DTO parts to be complete and accurate, all
NAVSUP Form 1250s for NIS and NC repair parts must
pass through the cost control clerk and the DTO clerk
before being submitted to the supply office. The supply
office maintains current procurement and shipping
status for items on order. When requesting the status of
a requisition from supply, DTO clerks must be able to
identify, by requisition number, the procurement
document they are interested in. Accurate DTO parts
records accomplish this and allow the cost control clerk
to identify the USN-number of the equipment each part
was ordered for. The DTO repair parts status keeping
system provides excellent accountability with
minimum effort. This system consists of two separate
records designed to be used together: the DTO log and
the repair parts summary sheets.
The DTO log (fig. 1-17) is a sequential record and
proof of order for all NAVSUP Form 1250-1/-2 requests
for NIS/NC/Non-NSN requirements submitted to the
repair parts storeroom. It is maintained in such a way
that the last NAVSUP Form 1250 entered is the last parts
request submitted to the supply office. This tells the
DTO clerk when the requisition was submitted to
supply. Normally, supply should order priority "A"
(NORS) requisitions within 24 hours and priority "B"
and "C" requisitions within 7 days.
accomplishing all ordering actions and issuing a
procurement document, supply enters the requisition
number in block "B" of a NAVSUP Form 1250-1 or
block "I" of a NAVSUP Form 1250-2. The pink copy is
returned to the repair parts storeroom where
outstanding requisition data is posted to stock record
cards for NIS items. The yellow copy is returned to the
cost control office to log the requisition number in the
DTO log. The yellow copy of NAVSUP Form 1250 is
retained as proof of order and maintained with the repair
parts summary sheet in the DTO files. The DTO log
provides a cross-index between the requisition number,
the department order number, and the USN number.
This cross-reference allows the DTO clerk to determine
the appropriate USN number for which the part was
ordered. This is invaluable for follow-up actions in the
event of lost or misfiled requisitions, lost or missing
shipping documents, partial or duplicate parts
shipments, and so forth.
The columns required to
maintain an effective DTO log are listed and explained
