APPENDIX B
MAINTENANCE ALLOCATION
Section I INTRODUCTION
B-1.
MAINTENANCE ALLOCATION CHART.
a. This Maintenance Allocation Chart (MAC) assigns maintenance functions in accordance with
the Three Levels of Maintenance concept for Army Aviation. These maintenance levels (categories) -
Aviation Unit Maintenance (AVUM), Aviation Intermediate Maintenance (AVIM), and Depot
Maintenance are depicted on the MAC as:
AVUM, which corresponds to an O Code in the Repair Parts and Special Tools List (RPSTL);
AVIM, which corresponds to an F Code in the Repair Parts and Special Tools List (RPSTL); DEPOT,
which corresponds to a D Code in the Repair Parts and Special Tools List (RPSTL).
b. The maintenance to be performed below depot and in the field is described as follows:
(1) Aviation Unit Maintenance (AVUM) activities will be staffed and equipped to perform high
frequency on-aircraft maintenance tasks required to retain or return aircraft systems to a serviceable
condition. The maintenance capability of the AVUM will be 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. The range and quantity of
authorized spare modules/components will be consistent with the mobility requirements dictated by
the air mobility concept. (Assignments of maintenance tasks to divisional company size aviation units
will consider the overall maintenance capability of the division, the requirement to conserve personnel
and equipment resources, and air mobility requirements.)
(a) Company Size Aviation Units: Perform those tasks which consist primarily of preventive
maintenance and maintenance repair and replacement functions associated with sustaining a high
level of aircraft operational readiness. Perform maintenance inspections and servicing to include
preflight, daily, intermediate, periodic (or phased), and special inspections as authorized by the
MAC or higher headquarters. Identify the cause of equipment/system malfunctions using applicable
technical manual troubleshooting instructions, built-in-test equipment (BITE), installed aircraft
instruments, or test, measurement, and diagnostic equipment (TM DE). Replace worn or damaged
modules/components that do not require complex adjustments or system alinement and which can be
removed/installed with available skills, tools, and ground support equipment. Perform operational
and continuity checks and make minor repairs to the electrical system. Inspect, service and make
operational, capacity, and pressure checks to hydraulic systems. Perform servicing, functional
adjustments, and minor repair/replacement to the flight control, propulsion, power train, and fuel
systems. Accomplish air frame repair that does not require extensive disassembly, jigging. or
alinement. The manufacture of air frame parts will be limited to those items which can be fabricated
with tools and equipment found in current air mobile tool and shop sets. Evacuate unserviceable
modules/components and end items beyond the repair capability of AVUM to the supporting AVIM.
(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 repair person and will normally be limited to preventive
maintenance, inspections, servicing, spot painting, stop drilling, application of nonstress patches,
minor adjustments, module/component fault diagnosis, and replacement of selected
modules/components. Repair functions will normally be accomplished by the supporting AVIM unit.
