intervals by the operator/crew.

item numbers for the TM Number column on DA Form 2404, Equipment Inspection and Maintenance Worksheet, in
recording results of PMCS.
c.
The service intervals are divided into four categories: B - Before Operation, D - During Operation, A-After
Operation, and W-Weekly. A dot (e) is placed in the interval column for each check or service. If the same check or
service is made in two or more intervals, a dot is placed in each applicable column.
d.
The ITEM TO BE INSPECTED column lists the item to be checked or serviced. This column is combined
with the PROCEDURE column.
e.
The PROCEDURE column describes the procedure by which the check or service is to be per- formed.
Illustrations are included to assist in locating that part of the equipment requiring the check or service. When instructions
for removal of assemblies or equipment are required in order to perform PMCS, they are listed and illustrated in the
PROCEDURE column.
