APPENDIX B
MAINTENANCE ALLOCATION
Section I INTRODUCTION
B-1. GENERAL.
This appendix provides a summary of maintenance operations for the radar signal detecting set.
It authorizes categories of maintenance for specific maintenance functions on repairable items
and components and the tools and equipment required to perform each function. This appendix may
be used as an aid in planning maintenance operations.
B-2. MAINTENANCE FUNCTIONS.
Maintenance functions will be limited to and defined as follows:
a. Inspect. To determine the serviceability of an item by comparing its physical, mechanical,
and/or electrical characteristics with established standards through examination.
b. Test. To verify serviceability and to detect incipient failure by measuring the
mechanical, or electrical characteristics of an item and comparing those characteristics with
prescribed standards.
c. Service. Operations required periodically to keep an item in proper operating condition,
i.e., to clean (decontaminate), to preserve, to drain, to paint, or to replenish fuel,
lubricants, chemical fluids, or compressed air supplies.
d. Adjust. To maintain, within prescribed limits, by bringing into proper or exact position,
or by setting the operating characteristics to specified parameters.
e. Aline. To adjust specified variable elements of an item to bring about optimum or desired
performance.
f. Calibrate. To determine and cause corrections to be made or to be adjusted on instruments
or test measuring and diagnostic equipment used in precision measurement. Consists of
comparisons of two instruments, one of which is a certified standard of known accuracy, to detect
and adjust any discrepancy in the accuracy of the instrument being compared.
g. Install. The act of emplacing, seating, or fixing into position an item, part, or module
(component or assembly) in a manner to allow the proper functioning of the equipment or system.
h. Replace. The act of substituting a serviceable like type part, subassembly, or module
(component or assembly) for an unserviceable counterpart.
i. Repair. The application of maintenance services (inspect, test, service, adjust, aline,
calibrate, replace) or other maintenance actions (welding, grinding, riveting, straightening,
facing, remachining, or resurfacing) to restore serviceability to an item by correcting specific
damage, fault, malfunction, or failure in a part, subassembly, module (component or assembly),
end item, or system.
