designates overall responsibility for the performance of maintenance functions on the identified end item
or component. Also included is a list of tools and test equipment required to do each maintenance
function (section 3).
MAINTENANCE FUNCTIONS

Service. Operations required periodically to keep an item in proper operating condition, i.e., to
clean (includes decontaminate when required), to preserve, to drain, to paint, or to replenish fuel,
lubricants, chemical fluids, or gases.
c.
Test. To verify serviceability by measuring the mechanical and electrical characteristics of an
item and comparing those characteristics with described standards.
d.
Adjust. To maintain, within prescribed limits, by bringing into proper or exact position, or by
setting the operating characteristics to specified parameters.
Replace. The act of substituting a serviceable like type part, subassembly, or module (component
e.
or assembly) for an unserviceable counterpart.

Repair. The application of maintenance services or other maintenance actions to restore
serviceability to an item by correcting specific damage, fault, malfunction, or failure in a part,
