procurement action may be taken until the increased
allowance has been approved. However, if the
requirement is considered to be an emergency, a
requisition may be submitted to a supply activity with
the approval of a superior m the chain of command.
Procurement of installed equipment is the
responsibility of and controlled by:
Naval Electronics Systems Command
Naval Sea Systems CommandOrdnance
Equipment and machinery for ships operation
Naval Sea Systems Command-Equipment and
machinery for ships operation.
Letter requests for installed equipment are
submitted by the commanding officer. A requisition
number must be assigned to these requests by the supply
Initial Equipment Installation
Most new equipment is installed during a shipyard
overhaul. The additional repair parts required are added
to the Stock-Number Sequence List-Storeroom Items
(SNSL-SRI) by personnel in the shipyard Supply
operations Assistance Program/ILO team. When new
equipment is installed between overhauls, supply
personnel must submit a Configuration Change Report
to Navy Ships Parts Control Center (SPCC). SPCC will
furnish the Allowance Parts List (APL) which supports
the equipment. The supply officer is responsible for
adding the allowed repair parts from the APL to the
SNSL-SRI and for ordering many deficient items.
Some specialized equipment may be received with
boxed sets of repair parts that are retained by the
department. Replenishment of these parts is retie on
the basis of a DTO request from the department as the
parts are used.
The basic policy and requisition procedures for
ammunition are contained in Commander Surface
Force instructions. Although the supply officer is not
responsible for preparing or following up on
ammunition requisitions, he will assist the weapons
officer, when requested, in preparing the proper
MANDATORY TURN-IN REPAIRABLE
Mandatory turn-in repairable (MTRs) are
high-cost items that cannot be repaired on board. They
are shipped to the nearest designated repair facility.
These items are procured and managed by the
applicable inventory manager on the assumption that
unserviceable repairable will be shipped promptly so
they can be repaired and placed in supply system stock
for reissue. In effect, repair becomes a substitute for
procuring replenishment system stock. For this reason,
control of unserviceable repairables is as important to
the Storekeeper as the control of serviceable material.
Mandatory turn-in repairable are identified by the
Material Control Code (MCC) appearing in the ML-1
and in the Master Repairable Item List (MRIL)
(NAVSUP Publication 4107). These codes are E, G, H,
Q, or X. Most mandatory turn-in repairables are
assigned MCC H; the other MCCs apply to
repairables that require special controls and handling.
MCC definitions are found in NAVSUP P-4107.
Advice codes must be assigned to all requisitions
for mandatory turn-in repairable items. Generally,
advice code 5G will be cited in replacement
requisitions. Advice codes are found m NAVSUP
These advice codes have precedence over any other
advice code that may apply applicable to the requisition.
When it is necessary to include additional advice codes
in a requisition for a mandatory turn-in repairable, it is
entered in the Remarks field, and the appropriate
document identifier for indicating exception data (A0E
or A05) must be entered in CC 13.
Requisition Document Numbers
Requisitions for replacement of mandatory turn-in
repairable must contain the same document number as
the turn-in document of the unserviceable repairable
that was shipped to the designated repair facility.
Requisitions for mandatory turn-in repairable will
be assigned priority 06 unless the urgency of need
justifies a higher priority.
