information about the AMMRL program.
This is a single alpha character code that provides
supplemental accountability details about an SE
transaction. Also, it shows the effects of transactions on
supply and financial records. The codes identify a
specific category of SE items placed in the custody of
an intermediate maintenance activity (IMA). IMA
issues the items to other activities on a subcustody basis.
The following paragraphs describes the custody codes.
Code D is assigned to items listed only in a
detachment list code, requiring management, and
having custody code of P or E. Code D will take
precedence in IMRL printing. The issuing of allowances
for items coded D is done in the same manner as the
P-coded item. For example, code D would apply to items
required on air capable ships by deployable
Code E is for items used infrequent y (less than once
per month). It means the item is available from the
supporting IMA as required. The IMA makes the item
available to activities. After use, the activities return the
item to IMA.
Code M is for noncalibratable items requiring
management that are not otherwise custody ceded. The
quantity authorized for these items is the total quantity
required for subcustody by each activity supported. An
example of an M-coded item is a carrying case for a
calibratable item when it is listed in the source data as a
separate end item. There are two steps for assigning
items in code M. First, the support equipment
controlling authority (SECA) identifies the item.
Second, NAVAIRENGCEN assigns code M to the item.
Code N is automatically assigned to items that do
not require calibration or management, and,
consequently, not otherwise coded. Code N is
automatically entered if the maintenance level is
Code P is for items weighing over 200 pounds (over
300 pounds for wheeled equipments). When authorized
for a supporting IMA, the IMA or MALS contingency
support package quantity is the total quantity required
for subcustody to each O-level maintenance activity.
The items are issued on a subcustody basis to squadrons
for full-time utilization. The squadron returns the item
to the IMA prior to deployment. While deployed, the
new supporting IMA issues these items to embarked
Code L is for all items requiring calibration and
management. These are items designated for use at
O-level maintenance and not already coded D, E, or P.
The quantity authorized is the total quantity required for
subcustody by each activity supported. The O-level
activities retain the items when deployed.
Individual Material Readiness List
The IMRL is a consolidated allowance list of
authorized quantities of SE items. These are items
required by an activity to perform its assigned
maintenance level functions. The following paragraphs
describe the terms used in IMRL.
Support eguipment (SE) refers to IMRL and
non-IMRL equipment required to make a system,
subsystem, or end item equipment operational.
The Primary Support Equipment Controlling
Authority (PSECA) is the term applied to
COMNAVAIRSYSCOM. The COMNAVAIRSYS-
COM functions as the centralized SE inventory
management authority. PSECA is responsible for
coordinating distribution of in-use assets among the
SECAs. Also, PSECA is responsible for prioritization
of SE procurement and distribution of new SE.
SECA is the term applied to major aviation
commands that exercise administrative control of
AMMRL Program SE end items. SECA performs the
allowance and inventory control of these items. The
following is a list of designated SECAs:
. Commander, Naval Air Force, Atlantic
. Commander, Naval Air Force. Pacific
l Chief of Naval Air Training (CNATRA)
. Commander, Naval Air Reserve Force
. Naval Air Maintenance Training Group
. Commander, Naval Air Systems Command
NOTE: COMNAVAIRSYSCOM has designated
Commanding Officer, Naval Aviation Maintenance
Office (NAMO) to execute SECA functions for all
NAVAIR field activities and depots. NAMO also has
SECA functions for naval weapons stations with SE
supplied by NAVAIR under the scope of the AMMRL
