Aviation Maintenance Allocation Chart
This MAC (immediately following the introduction) designates overall authority and responsibility for the perfor-
mance of maintenance functions on the identiied 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 Mainte-
nance Group (TASMG) and other organizations that have National Maintenance Program Certiication

The maintenance to be performed below depot and in the ield is described as follows:
Aviation Maintenance Company (AMC). The primary purpose of the Aviation Maintenance Company
is to support the momentum of offensive operations. Composition of the AMC will be based on type of op-
erations being supported, nature of the battleield, and the need for lexibility. 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, es-
sential parts, and supplies. 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 Management/Maintenance Test Pilot functions. AMCs will rig aircraft for re-
covery 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 pla-
toons, which are conigured to maintain unit level operational 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 lights and return of repaired aircraft, enforces quality standards, responsible for safety. Also,
