c.
A
maintenance
function
assigned
to
a
maintenance category will automatically be authorized to
be performed at any higher maintenance category.
d. A maintenance function that cannot be performed
at the assigned category of maintenance for any reason
may be evacuated to the next higher maintenance
category. Higher maintenance categories will perform the
maintenance functions of lower maintenance categories
when required or directed by the commander that has the
authority to direct such tasking.
e. The assignment of a maintenance function will
not be construed as authorization to carry the related
repair parts or spares in stock. Information to requisition
or otherwise secure the necessary repair parts will be as
specified in the associated repair parts and special tools
list (RPSTL).
f. Normally there will be no deviation from the
assigned level of maintenance. In cases of operational
necessity,
maintenance
functions
assigned
to
a
maintenance level may, on a one-time basis and at the
request of the lower maintenance level, be specifically
authorized by the maintenance officer of the level of
maintenance to which the function is assigned. The
special tools, equipment, etc. , required by the lower
level of maintenance to perform this function will be
furnished by the maintenance level to which the function
is assigned. This transfer of a maintenance function to a
lower maintenance level does not relieve the higher
maintenance level of the responsibility for the function.
The higher level of maintenance will provide technical
supervision
and
inspection
of
the
function
being
performed at the lower level.
g. Changes to the maintenance allocation chart will
be based on continuing evaluation and analysis by
responsible technical personnel and on reports received
from field activities.
B-3. 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 (e. g. , by sight, sound, or feel).
b. Test. To verify serviceability by measuring the
mechanical,
pneumatic
hydraulic,
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
(includes decontaminate when required), to preserve, to
drain, to paint, or to replenish fuel, lubricants, chemical
fluids, or gases.
d. Adjust. To maintain or regulate 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 equipments 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. Remove/Install. To remove and install the same
item when required to perform service or other
maintenance functions. Install may be the act of
emplacing, seating, or fixing into position a spare, repair
part, or module (component or assembly) in a manner to
