FIELD MAINTENANCE
PMCS INTRODUCTION
GENERAL
When performing a PMCS or simple routine checks, observe all WARNINGSlisted in the WARNING SUMMARY at
the beginning of this manual and interspersed throughout.
Preventive maintenance is the systematic care, servicing, and inspection of equipment to prevent the occurrence
of problems, to reduce downtime, and to maintain equipment in serviceable condition. To ensure that the
equipment is always ready for a mission, perform the scheduled Preventive Maintenance Checks and Services
(PMCS) (WP 0019).
This section lists the required Preventive Maintenance Checks and Services for the MT3 SATS. Always keep in
mind the Warnings listed in the WARNING SUMMARY. To ensure that the MT3 SATS is ready for operation at
all times, it must be inspected systematically so defects may be discovered and corrected before they result in
serious damage of equipment failure. The necessary preventive maintenance checks and services that are to be
performed by personnel are listed and described in WP 0017.
Routine maintenance like cleaning, washing, corrosion control, storage and shipping etc., are not listed as part
of the PMCS. These tasks should be performed when they are needed.
Determining PMCS Intervals
PMCS is performed on a weekly, monthly, semi-annually or annually basis as indicated in (WP 0004 and
PMCS for Units in Continuous Operation
The running time meter is used to determine SATS operating time. For PMCS performed on an operating time
basis, perform PMCS as close as possible to the time intervals indicated. For units in continuous operation,
perform PMCS before starting operation (WP 0019). If continuous operation extends service past that which is
shown, perform PMCS or scheduled service upon completion of mission or before next operation.
Defects
Deiciencies that cannot be corrected must be reported on DA Form 2404 or DA Form 5988-E to maintenance
personnel. Records and reports of preventive maintenance must be iled and maintained IAW DA PAM 750-8.
