PREVENTIVE MAINTENANCE CHECKS AND SERVICES (PMCS) INTRODUCTION
GENERAL (PMCS), REPORTING ERRORS, AND GENERAL SERVICE AND INSPECTION PROCEDURES
GENERAL (PMCS)
The best way to maintain boats covered by this manual is to inspect them on a regular basis so minor
faults can be discovered and corrected. This will help prevent serious damage or failure of the boat and
equipment, or injury to personnel. WP 0011 00 contains systematic instructions for inspection, adjustment,
and correction of boat components to avoid costly repairs or major breakdowns. This is referred to as
Preventive Maintenance Checks and Services (PMCS).
REPORTING REPAIRS
Uncorrected defects will be recorded on the Equipment Inspection and Maintenance Worksheet, DA Form
2404 or DA Form 5988-E (automated), in accordance with DA Pam 750-8.
GENERAL SERVICE AND INSPECTION PROCEDURES
Definitions of class I, II, and III leaks and their effect on boat operation are listed in
TM 5-1940-322-10.
While performing specific PMCS procedures, verify items are correctly assembled, secure, serviceable, not
worn, not leaking, and adequately lubricated as defined below:
1.
An item is CORRECTLY ASSEMBLED when all parts are present and in proper position.
2.
When wires, nuts, washers, hoses, or attaching hardware cannot be moved by hand, wrench, or prybar,
they are SECURE.
3.
An item is UNSERVICEABLE if worn beyond established wear limits or likely to fail before the next
scheduled inspection.
4.
An item is WORN if there is play between joining parts, or warning and caution plates are not
