(b) Less than Company Size Aviation Units:
Aviation elements organic to brigade, group, battalion
headquarters, and detachment size units are normally small and have less than 10 aircraft assigned. Maintenance
tasks performed by these units will be those which can be accomplished by the aircraft crew chief or assigned
aircraft repairman and will normally be limited to preventive maintenance, inspections, servicing, spot painting,
module/component fault diagnosis, and replacement of selected modules/components. Repair functions will normal-
ly be accomplished by the support AVIM unit.
(2) Aviation Intermediate Maintenance (AVIM).
(a) Provides mobile, responsive “One Stop” maintenance support. (Maintenance functions which are not
conducive to sustaining air mobility will be assigned to depot maintenance.)
(b) 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 replace-
ment and repair of modules/components and end items which can be accomplished efficiently with available skills,
tools, and equipment.
(c) 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.
(d) 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
replacement of seals, fittings, and items of common hardware. Airframe repair and fabrication of parts will be limited
to those maintenance tasks which can be performed 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.
(e) Performs aircraft weight and balance inspections and other special inspections which exceed AVUM
capability.
(f) 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.
(g) Maintains authorized operational readiness float aircraft.
(h) Provides collection and classification services for serviceable/unserviceable material.
(i) Operates a cannibalization activity in accordance with AR 750-1. (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.)
