PREVENTIVE MAINTENANCE CHECKS AND SERVICES (PMCS)
INTRODUCTION
GENERAL
Unit PMCS are performed at regular intervals to ensure the equipment is fully operational and ready at
all times. Maintaining the IRB-R and IRB-I requires inspection on a regular basis so minor damage or
faults can be discovered and corrected. Performing PMCS is essential to the reliability and expected
longevity of the equipment. Failing to correct a minor problem may result in major damage or a failure
which could compromise the mission or cause injury to personnel.
PURPOSE OF PMCS TABLES
The purpose of the PMCS tables is to provide a systematic method of inspecting and servicing the
equipment. In this way, small defects can be detected early and corrected before they become a major
problem causing the equipment to fail. The PMCS tables are arranged with the individual PMCS
procedures listed in sequence under assigned intervals. The most logical time (before or after mission) to
perform each procedure determines the interval to which it is assigned. Make a habit of performing the
checks in the same order each time; anything wrong will be seen quickly. Refer to WP 0018 00 for PMCS
instructions in tables 1 and 2.
