APPENDIX B

MAINTENANCE ALLOCATION

Section I INTRODUCTION

B-1. GENERAL.

This appendix provides a summary of maintenance operations for the test 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, ie, to

clean (decontaminate), to preserve, to drain, to paint, or to replenish fuel, lubricants, chemical

fluids, or compressed air suppiles.

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 or adjustments to be made on instruments or

test, measurement, and diagnostic equipment used in precision measurement. Consists of compari-

sons 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, cali-

brate, 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 part, subassembly, module (component or assembly), end item, or

system.
