Table 3-5.-Joint Services Uniform SM&R Code Format
The P-Series Source codes identify items that are
centrally procured. These items (except PF items) are
procured and stocked in the supply system.
The K-series Source codes identify the items that
are included in kits and do not/will not have an NSN
assigned.
The M-Series Source codes identify the items that
are authorized for manufacture or fabrication at some
level of maintenance. These items are normally
consumable or those requiring very limited repair.
Some typical “M” coded items include hose
assemblies, tubing, and name plates. The specified
level of maintenance must have all the manufacturing
data, shop equipment, and skills available to
manufacture the items.
The A-Series Source codes identify the items that
are authorized for assembly at some level of
maintenance. These codes can be assigned to an item
when all parts of the assembly, support equipment, and
skills are available at the level of maintenance.
The X-Series Source codes identify items for which
no demand is anticipated.
The Maintenance codes are two-position codes
that show the level of maintenance authorized to use,
remove or replace, and repair items. Maintenance
codes occupy the third and fourth positions of the
SM&R code format.
The maintenance code entered in the third position
indicates the maintenance level authorized to use, remove,
and replace the support item. When used for end items,
maintenance tools, test, and support equipment items, a
code in this position indicates the lowest level of
maintenance authorized to use this item.
The maintenance code entered in the fourth position
indicates whether the item is to be repaired. It also
identifies the lowest level of maintenance to accomplish
overhaul, repair, or assembly of the item.
The Recoverability code occupies the fifth position of
the SM&R code format. This code indicates the
recoverabtilty potential of the item. It also indicates the
final disposition of unserviceable items. For repairable
items, this code means the maintenance level responsible
for repair, condemnation, and disposal of the item.
The procedures for submitting SM&R code change
request are outlined in NAVAIRINST 4423.11. It
provides detailed instructions for preparing the SM&R
code change request form, NAVAIR Form 4423/1.
TECHNICAL LIBRARY MANAGEMENT
The Central Technical Publications Library
(CTPL) provides a source of current information
needed by supply and maintenance personnel. The
quality assurance/analysis (QA/A) division of
Aircraft Intermediate Maintenance Department
(AIMD) manages the CTPL. This function includes
updating the publications throughout the activity
when AIMD is responsible for all aeronautical
technical manuals for the activity. The AK may use
the CTPL to verify or find technical information
needed to do the job. Aviation support activities not
adjacent to AIMD require a library with an appropriate
number of publications necessary to conduct technical
research. This library is a dispersed library of the
AIMD CTPL and is usually located in the supply
response section (SRS). The SRS supervisor is
responsible for ensuring that all necessary technical
publications are on hand and readily available in the
library.
