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 main-
tenance includes replacement and repair or 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 troubleshoots performs diagnostic tests, repairs, adjusts, calibrates, and
aligns 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 repalcement 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 item 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. 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. Maintains authorized operational readiness float aircraft. Provides
collection and classification services for serviceable/unserviceable material. 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 the air mobility requirements and conservation of personnel and
equipment resources. Additional intermediate maintenance support will be provided by the supporting nondi-
visional AVIM unit.
(2) Aviation Intermediate Maintenance (AVIM) provides mobile, responsive “One-Stop” mainte-
nance 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
