B-1.

(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 return to user will emphasize 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

establishes 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, trouble-

shoots, 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 replacement of seals, fittings, and items of common hardware. Air-

frame repair and fabrication of parts will be limited to those maintenance tasks which can be per-

formed with available tools and test equipment. Unserviceable reparable modules/components and

end items which are beyond the capability of AVIM to repair will be evacuated to Depot Maintenance.

AVIM will perform aircraft weight and balance inspections and other special inspections which exceed

AVUM capability, AVIM provides quick response maintenance support, including aircraft recovery and

air evacuation, on-the-job training, and technical assistance through the use of mobile maintenance

contact teams. AVIM maintains authorized operational readiness float aircraft and provides collection

and classification services for serviceable/unserviceable material. (The aircraft maintenance

company within the maintenance battalion of a division will perform AVIM functions consistent with air

mobility requirements and conservation of personnel and equipment resources. Additional

intermediate maintenance support will be provided by the supporting nondivisional AVIM unit.)

B-2. USE OF MAINTENANCE ALLOCATION CHART (SEC II).

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) Worktime 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 (eg, 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).
