Purpose of PMCS Table.  The purpose of the PMCS table is to provide a systematic method of inspection  and  servicing  the  equipment.  In  this  way,  small  defects  can  be  detected  early  before  they  become  a major problem causing the equipment to fail to complete its mission. The PMCS table is arranged with the individual PMCS procedures listed in sequence under assigned intervals. The most logical time (before, during, or after operation) to perform each procedure determines the interval to which it is assigned. Make a habit of doing the checks in the same order each time and anything wrong will be seen quickly. See paragraphs 2-5 and 2-6 for an explanation of the columns in table 2-1. 2-5. Explanation Of Columns.  The following is a list of the PMCS table column headings with a description of the information found in each column. a. Item No. This column shows the sequence in which the checks and services are to be performed, and is used  to  identify  the  equipment  area  on  the  Equipment  Inspection  and  Maintenance  Worksheet,  DA  Form  2404. b. Interval.  This column shows when each check is to be done. c. Item to be lnspected/Procedures.   This column identifies the general area or specific part where the  check or service is to be done, and explains how to do them. d. Equipment is Not Ready/A vailable  If.   See paragraph  2-6. 2-6. Equipment is Not Ready/Available If Column.  This column lists conditions that make the equipment unavailable for use because it is unable to perform its mission, or because it would represent a safety hazard. Do not accept or operate equipment with a condition in the “Equipment is Not Ready/Available If” column. 2-4
