May perform all maintenance functions authorized to be done at AVUM. Repair of equipment for return to
user will emphasize support of operational readiness requirements. Authorized maintenance includes
replacement and repair of modules/components and end items that can be accomplished efficiently with
available skills, tools, and equipment.
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.
Inspects, troubleshoots, performs diagnostic tests, repairs, adjusts, calibrates, and aligns aircraft system
modules/components. AVIM units will have the 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. Airframe
repair and fabrication of parts will be limited to those maintenance tasks that can be performed with
available tools and test equipment. Unserviceable reparable modules/components and end items that
are beyond the capability of AVIM to repair will be evacuated to depot maintenance.
Performs aircraft weight and balance inspections and other special inspections that exceed AVUM
Provides quick response maintenance support, including aircraft recovery and air evacuation, on-the-job

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 non-divisional AVIM unit.
Depot - The printed wiring assemblies (PWAs) are sent back to the depot/factory for repairs.
The Tools and Test Equipment Requirements work package (immediately following the MAC) lists the tools and test

This MAC assigns maintenance functions to the lowest level of maintenance, based on past experience and the
Work time required
Tools and test equipment required and/or available
Only the lowest level of maintenance authorized to perform a maintenance function is indicated. If the lowest
maintenance level 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.
