B1. GENERAL. Continued
(2) Aviation Intermediate Maintenance (AVIM) provides mobile, responsive One-Stop maintenance support.
(Maintenance functions which are not conducive to sustaining air mobility will be assigned to depot maintenance). AVIM
may perform all maintenance functions authorized to be done at AVUM. Repair of equipment for retum to user will empha-
size support or operational readiness requirements. Authorized maintenance includes replacement and repair of modules/
components and end items which can be accomplished efficiently with available skills, tools, and equipment. AVIM esta-
blishes the Direct Exchange (DX) program for AVUM units by repairing selected items for return to stock when such
repairs cannot be accomplished at the AVUM level. The AVIM level inspects, troubleshoots, performs diagnostic tests,
repairs, adjusts, calibrates, and alines aircraft system modules/components. AVIM units will have capability to determine
the serviceability of specified modules/components removed prior to the expiration of the Time Between Overhaul (TBO)
or finite life. Module/component disassembly and repair will support the DX program and will normally be limited to tasks
requiring cleaning and the fabrication of seals, fittings, and items of common manufacture. Airframe repair and fabrication
of parts will be limited to those maintenance tasks which can be performed with available tools and test equipment. Unser-
viceable repairable modules/components and end items which are beyond the capability of AVIM to repair will be eva-
cuated to Depot Maintenance. AVIM will perform aircraft weight and balance inspections and other special instructions
which exceed AVUM capability. Provides quick response maintenance support, including aircraft recovery and air evacua-
tion, on-the-job training, and technical assistance through the use of mobile maintenance contact teams. Maintains autho-
rized operational readiness float aircraft. Provides collection and classification services for serviceable/unserviceable ma-
terial, Operates a cannibalization activity in accordance with AR 750-50. (The aircraft maintenance company within the
maintenance battalion of a division will perform AVIM functions consistent with air mobility requirements and conserva-
tion of personnel and equipment resources. Additional intermediate maintenance support will be provided by the support-
ing nondivisional AVIM unit.)
B-2. USE OF THE MAINTENANCE ALLOCATION CHART
a. The Maintenance Allocation Chart assigns maintenance functions to the lowest 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 main-
tenance 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 parts or spares
in stock. Information to requisition or otherwise secure the necessary repair parts will be as specified in the associated Re-
pair Parts and Special Tools List (RPSTL).
f. Normally there will be no deviation from the assigned level of maintenance. In cases of operational necessity, main-
tenance 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.
