(d) The hydraulic system is inspected, serviced, and checked for operation, capacity, and pressure
(e) The manufacture of parts is limited to those items which can be fabricated with tools and equipment
found in current air mobile tool and shop sets.
(f) Unserviceable modules/components, and end items beyond the repair capability of AVUM, are sent
to the support AVIM.
(4) Tasks Assigned to 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.
(a) Maintenance tasks performed by these units will be those which can be accomplished by the
aircraft crew chief or assigned aircraft repairman.
(b) Tasks will normally be limited to preventive maintenance, inspections, servicing, spot painting,
module/component fault diagnosis, and replacement of selected modules/components.
(c) Repair tasks will normally be accomplished by the support AVIM unit.
b. Aviation Intermediate Maintenance (AVIM). The AVIM activities are staffed and equipped to perform mobile,
responsive "One-Stop" maintenance support. The AVIM activities may perform all maintenance functions authorized at
the AVUM level. Authorized maintenance includes replacement and repair of components or end items, which can be
accomplished efficiently with available skills, tools, and equipment. Maintenance functions which are not conducive to
sustaining air mobility will be assigned to depot maintenance. Repair of equipment for return to user will emphasize
support or operational readiness requirements.
(1) Maintenance Capability. The maintenance capability of the AVIM is governed by the Maintenance
Allocation Chart (MAC) and limited by the amount and complexity of ground support equipment (GSE), facilities required,
authorized manning strength, and critical skills available.
(2) Authorized Spares. The range and quantity of authorized spare components will be consistent with the
mobility requirements dictated by the air mobility concept.
(3) Direct Exchange. Repairs selected items for return to stock and establishes the Direct Exchange (DX)
program for AVUM units, when such repairs cannot be accomplished at the AVUM level.
(4) Serviceability. The AVIM units will have capability to determine the serviceability of specified
components removed prior to the expiration of the Time Between Overhaul (TBO) or finite life. The AVIM inspects,
troubleshoots, performs diagnostic tests, repairs, adjusts, calibrates, and aligns aircraft support system components.
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. Unserviceable repairable components and end
items, which are beyond the capability of AVIM to repair, will be evacuated to Depot Maintenance.
(5) Weight and Balance. Performs aircraft weight and balance inspections and other special inspections
which exceed AVUM capability.
(6) Quick Response. 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.
(7) Operational Readiness. Maintains authorized operational readiness float aircraft.
