MAINTENANCE ALLOCATION CHART (MAC) INTRODUCTION
Aviation Maintenance Allocation Chart
The MAC (immediately following the introduction) designates overall authority and responsibility for the performance
of maintenance functions on the identified end item or component. The application of the maintenance functions to
the end item or component shall be consistent with the capacities and capabilities of the designated maintenance level
which are shown on the MAC as:
Field - includes two columns, "O" which corresponds to Aviation Maintenance Company (AMC) and "F" which
corresponds to Aviation Support Battalion (ASB)
Sustainment - includes two columns, "L" which corresponds to Theater Aviation Sustainment Maintenance

Aviation Maintenance Company (AMC). The primary purpose of the aviation maintenance company is to
1.
support the momentum of offensive operations. Composition of the AMC will be based on type of operations
being supported, nature of the battlefield, and the need for flexibility. AMCs will provide forward positioning
of essential maintenance repair parts and supplies, maximum use of support teams, use of airlift/air drops
for resupply, for maintenance that does not interfere with the tactical plans and operations. AMCs are agile,
mobile, and well equipped. They will carry limited stockpiles of demand supported, essential parts and sup-
plies. The AMC performs battle damage assessment and repair (BDAR) and unit level repairs on Aviation Life
Support Systems (ALSS). The AMC performs production control, quality control, and Maintenance Manage-
ment/Maintenance Test Pilot functions. AMCs will rig aircraft for recovery operations. The AMC manages
the battalion maintenance program and operates a central tool room. The AMC conducts forward arming and
refueling. AMCs will be comprised of 3 to 4 modular platoons, which are configured to maintain unit level op-
erational readiness and aircraft availability:
Headquarters Platoon - Establishes standard operating procedures, receives and processes work
requests, schedules maintenance, maintains status of aircraft, coordinates inspections and test flights
and return of repaired aircraft, enforces quality standards, responsible for safety. Also, obtains, stores,

power tools, test, measurement, and diagnostic equipment, welding and cutting equipment, and an air
compressor. The SECM truck is highly mobile.
