CHECKS AND SERVICES (PMCS)
Preventive Maintenance Checks and Services (PMCS) will ensure that the Aviation Mission Planning System
(AMPS) equipment will be ready for operation at all times. Preventive maintenance checks consist of performing
a systematic inspection to discover defects before they result in operational failure of the equipment. Defects or
malfunctions discovered by the crew during use of the AMPS equipment, or as a result of performing
maintenance checks and services, will be reported using the proper maintenance reporting procedures IAW DA
PAM 738-751, Functional Users Guide for the Army Maintenance Management System Aviation (TAMMS-A).
