Purpose of PMCS Table. The purpose of the PMCS table is to provide a systematic method of inspecting 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 2-7 and 2-8 for an explanation of the columns in table 2-1.
2-7.
