Section II. OPERATOR AND CREW PREVENTIVE MAINTENANCE
48. General
To insure that the equipment is ready for operation at all times, it must be inspected systematically before
operation, during operation, at halt, and after operation, so that defects may be discovered and corrected
before they result in serious damage or failure. The necessary preventive maintenance services will be
performed before operation. Defects discovered during operation of the unit will be noted for further correction,
to be made as soon as operation has ceased. Stop operation immediately if a deficiency is noted during
operation which would damage the equipment if operation were continued. After-operation services will be
performed by the operator after every operating period. After-operation services will be performed at intervals
based on the normal operations of the equipment. Reduce intervals to compensate for abnormal conditions.
Defects or unsatisfactory operating characteristics beyond the scope of the operator to correct must be reported
at the earliest opportunity to organizational maintenance. The responsibility for performance of preventive
maintenance services rests not only with the operator, but with the entire chain of command from section chief
to commanding officer. (AR750-5).
