TM55-1680-358-12&P
category of maintenance based on past experience and the following considerations:
(1)
Skills available
(2)
Work time required.
(3)
Tools and test equipment required and/or available.
b.
Only the lowest category of maintenance authorized to perform a maintenance function is indicated. If the lowest
maintenance category cannot perform all tasks of any single maintenance function (e.g., test repair), then the higher
maintenance level(s) that can accomplish additional tasks will also be indicated.
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.
