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
f. Normally there will be no deviation from the
assigned level of maintenance. In cases of operational
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
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.
