PMCS PROCEDURES
Work Packages 0016 00 through 0019 00 contain operator's PMCS procedures. The procedures are arranged in a logical sequence
requiring a minimum amount of time and motion on the part of the person(s) performing them and are arranged so there will be a
minimum of interference between person(s) performing checks simultaneously on the same end item.
Item No. Column. Checks and services are numbered in chronological order regardless of interval. Use this column as a source of
item numbers for the "TM Number" column on DA Form 2404/5988-E, Equipment Inspection and Maintenance Worksheet, in
recording results of PMCS.
Manhour Column. This column lists the manhours required for the item to be checked or serviced.
Interval Column. The words in the Interval column indicate when the checks or services are to be done as follows:
a. If a given check is performed before, during, or after an operation, the word BEFORE, DURING, or AFTER will be in this
column, respectively.
b. If the same check is made at two or more intervals, the appropriate words will appear in the column.
Location, Item to Check/Service Column. Indicates location and/or the item to be checked and/or serviced. The items to be
inspected are identified by as few words, usually the common name, as will clearly identify the item, e.g., "Drive Belts."
